For conservatory companies seeking new avenues for their business, larger and commercial projects could open doors to different and potentially lucrative markets.  Here, several fabricators share their experiences with Conservatory Magazine and describe a few different and more challenging applications for conservatory roofs.

Conservatories are getting bigger.  Of course there is still a market for small domestic, usually white PVC-U conservatories, but the demand for individually designed structures is certainly growing, and conservatories continue to feature in the top three on homeowners’ home improvement wish lists. 

Traditional style orangeries, impressive swimming pool covers or spacious additions to hotels, schools or offices could all prove to be lucrative projects for fabricators.  However, there are a few important considerations to be made before venturing into this marketplace.

Fabrication and installation of large conservatories is very specialised, and it is vital that the undertaking is properly managed and appropriate expertise is available to see it through to completion.  One roof could take up the entire space in a factory, as well as requiring extra manpower and time, and will take several installation teams.  A word to the wise here: a sizable proportion of cash could be tied up in just one project.  But if all these issues can be addressed, there are significant rewards to be reaped.

A bigger construction needs a substantial supporting sub-structure to carry the weight of the glazed roof.  On small conservatories this weight is, in the main, carried by the side frames, but this would not be feasible for larger roofs. 

A structural engineer must be consulted at the start of the project.  He will produce a full report based on the locality and intended use of the proposed conservatory, and calculate the dimensions for a portal frame which can then be constructed from steel or aluminium.

Aluminium is lighter and easier to handle, but the beams may need to be thicker to incorporate enough strength. Steel is much heavier and stronger, and could require lifting with a crane, but the beams needn’t be as thick. Either material can either be powder-coated before installation, painted or clad with PVC-U when construction is complete.

David Franklin of Franklin Conservatories, based at Yeadon near Leeds, describes how his company prefers working with a portal frame.  “We have developed an efficient way of working when a portal is required,” he says. 

“We put down the concrete pads that the framework stands on even before the footings are excavated, then erect the portal and put on the roof.  This means that then we can dig the footings and build the brickwork, keeping everything dry – which is a real consideration in this country!

“The bricks can be laid to exact dimensions and the window frames installed easily.  This whole system of working gives a very tidy structure which has exceptional integrity.”

Sturdy ‘Wide-span’ glazing bars enable lean-to conservatories with a span of up to 4.2m, fully glazed with either glass sealed units or polycarbonate, to be built without the need for portal frames, purlins or tie bars. 

An excellent example of this method of construction is a stunning silver wrap-round lean-to conservatory which was incorporated into the plans for a new NHS administrative building in Yeovil, Somerset.

“The conservatory is used as a common room, and was built as part of a multi-million pound development by the NHS in this area” explains Andrew Genko, Managing Director of Regent RS, who fabricated and installed the eye catching structure.  “It measures ten metres by nine metres and was constructed using Quantal ‘Wide-span’ glazing bars, which enabled it to be built without a portal frame.

“The roof was sprayed silver both internally and externally in Quantal’s in-house paint shop to match the windows, and the overall appearance is very high-tech and modern to compliment the brand new building.

“The roof is glazed with 24 mm polycarbonate, and features automatic roof vents to keep the temperature in the extra space comfortable, even on the warmest days,” adds Andrew.

Devon based roof fabricator AGS Home Improvements has worked closely with a Kingsbridge firm of architects on a number of hotel-based installations.  Paul Symons, Contracts Manager at AGS, explains that the architect specifies the Quantal roof because of its inherent strength, versatility and authentic good looks.

“At the Langstone Cliff Hotel in Dawlish, extensive expansion work could have meant that large areas would never benefit from natural light.  However, clever use of glass roof lights allows daylight into otherwise dark corners.

“Four small roofs have been incorporated into the ballroom extension, whilst another lightens the entrance to the snooker room.  A strategically placed roof above a newly built stair well allows natural light into an area that would otherwise need to be lit 24 hours a day.  Panelling and chandelier make a stylish feature of the extension.”

The same architect has worked with AGS on the luxurious Thurlestone Hotel near Kingsbridge in Devon.  Following a refurbishment of the swimming pool at the site, AGS installed glass roofs in the changing rooms.

“The roofs are extremely practical for this application, because they have roof vents to disperse the inevitable build-up of steam and condensation from the showers,” says Paul.  “In addition, the hotel insisted that they should look attractive when hotel guests looked down onto the pool from upper floor rooms, so a special stone surface was applied to the flat roof and elegant solid cast aluminium cresting and finial finished the roof perfectly.

“In order to ensure the absolute safety of the public, these commercial installations have to be glazed with special reinforced toughened glass which is much heavier than the glass used in standard installations.  The Quantal roof is strong enough to easily accept the extra weight, and the versatility of the system makes it perfect for this kind of application.”

A conservatory built for a customer in America by Nailsworth based Trade Plas gave a whole new meaning to ‘bespoke’, pushing the boundaries of design, fabrication and installation to their very limits.

The stunning structure, built to take full advantage of magnificent views over a nearby lake, was designed to replace the wooden gable roof over the kitchen with glass, and to provide a dining room and smoking area.

Although the conservatory was treated as three separate installations, the entire construction was supported by a complicated steel portal frame manufactured by a Stroud engineer.

The original timber roof was removed from the kitchen area of the house and replaced with the first of the three conservatory roofs.  Valleys were installed on the existing timber frame.  The roof is six and a half metres in length, and overhangs the second roof by 300mm to mirror the overhang of the roof on the rest of the property.  The second roof has four thermostatically controlled electric roof vents, is six and a half metres in length and again overhangs the third roof by 300mm.

For the third roof, the homeowner wanted a Victorian style conservatory with a gable front.  The innovative design features an aluminium sunburst across the gable, which is supported by the Quantal structural gable lintel, is three and a half metres in length with a 300mm overhang at the front.

The installation impressed the judges at the recent Glassex Conservatory Design Competition, where it won a bronze medal.  Rob Williams, sales manager at Trade Plas, sums up the installation.  “We are very proud to have been recognised for the innovative design, manufacture and installation of this unique structure.  A project of this magnitude takes an incredible amount of management, especially when it is taking place thousands of miles away.”

Nailsworth based Quantal Approved Installer Trade Plas has won an award in the prestigious Glassex Conservatory Design Competition for the third successive year.

Rob Williams, Sales Manager, was presented with the Bronze award in the Innovative Design category by Vanda Murray OBE, MD of Ultraframe, who sponsored the awards for the competition.

The stunning structure was built for a Trade Plas customer in America, to take full advantage of surrounding magnificent views.  The conservatory was designed to replace the gable over the kitchen with glass, and to provide a dining room and smoking area stretching out towards a nearby lake.

The conservatory was treated as three separate installations.  The entire construction was supported by a complicated portal frame manufactured by a Stroud engineer and shipped over to West Coast USA along with the Quantal roofs, windows, doors and glazing units from the factory in Nailsworth, Gloucestershire, to be installed by Trade Plas’ own fitters, Ashley Roache and James Tearle.

The original timber roof was removed from the kitchen area of the house and replaced with the first of the three conservatory roofs.  Valleys were installed on the existing timber frame.  The roof is 6 ½ metres in length, and overhangs the second roof by 300mm.  The second roof has four thermostatically controlled electric roof vents, is 6 ½ metres in length and again overhangs the third roof by 300mm.

For the third roof, the homeowner wanted a Victorian style conservatory with a gable front.  The innovative design features an aluminium sunburst across the gable, which is supported by the Quantal structural gable lintel, is 3 ½ metres in length with a 300mm overhang at the front.

Rob sums up the installation:  “This conservatory gives a whole new meaning to ‘bespoke’, pushing the boundaries of design, fabrication and installation to their very limits.  The strength and versatility of the Quantal roof helped to make this possible.

“We are very proud to have been recognised for the innovative design, manufacture and installation of this unique structure, and equally delighted to be here for the third time running.”

Franklin Conservatories has been voted ‘Supreme Winner’ in the Glassex 2006 Conservatory Design Competition.

Following their success in last year’s competition, Quantal Approved Installer Franklin won Gold and Silver in the ‘Large Conventional’ category this year. 

As overall winner, Franklin received £5,000 of IT equipment, which included a laptop and RoofWright configuration software, sponsored by Ultraframe.

Design Competition judge Barry Dunlop, MD of ebuilders, explained that the judges were unanimous in selecting Franklin’s gold winner as ‘best in show’.  He said: “This is an outstanding conservatory that is a true luxury room.  The care and attention to detail is evident everywhere.”

David Franklin said that the client had spent over 12 years researching conservatories and orangeries, before making the final decisions on finer details like pillars, cornice details etc.

“The flat leaded roof area provided an interesting feature and helped to maintain the view of the garden from the upstairs window, while the narrow spacing on the roof bars gave a traditional look.

“The lead grey Quantal roof with its pleasing aesthetics perfectly complimented the real rolltop leaded box gutter. 

“The roof is glazed with highest performance Derby glass, and features four automatic roof vents, whilst water-filled under-floor heating ensures a comfortable living environment all year.

“The frames were all hardwood with surface mounted Georgian bars, hand painted in Farrow and Ball French Grey.  As a final touch, the existing house doors were removed to make the conservatory part of the house. 

“By working closely with the clients, listening to their ideas and requirements, we have achieved this unique and beautiful structure.

“We are very proud to have been awarded this prestigious accolade,” concludes David.

Quantal Approved Installer CTG used its local knowledge to design and build this stunning conservatory in St Ives.  The homeowners can enjoy the beauty of the Cornish countryside safe in the knowledge that their conservatory can withstand the worst of the Atlantic coast’s weather conditions.

Ian Deacon, General Manager of CTG, explains:  “Because we are based in this area we know about the extremes in climate that our customers are exposed to, so when the homeowners approached us to build them a conservatory that they could use all year round we knew we would have to design a high performance structure with a ‘most severe weather rating’.” 

The integral strength and aluminium top caps of the Quantal roof gives it an enormous advantage over similar plastic capped roofs, which are susceptible to problems caused by storm damage.  And the tough polyester powder coating on all visible surfaces is extremely durable and easy to keep clean.

“In addition they of course wanted their conservatory to look stylish and enhance their home, so are delighted with the finished product that features a superior high gloss finish and distinctive aesthetics, as well as the very latest high quality security hardware and solar control glass,” concludes Ian.

The benefits of adding a conservatory during the construction of new houses are many for both the builder and the occupier.  Ian Cocken, National Sales Manager for Quantal Conservatory Roofing Systems advises how fabricators and installers can make their conservatory offer attractive to builders and developers.

For the homeowner, completion at the same time as the property means no VAT, no mess and disruption during installation, building materials can be matched perfectly and planning permission and building regulations are dealt with by the builder.  When the property is finished the conservatory is immediately ready to enjoy as an integral part of the new home.  It is a way to personalise their home, to stamp their individuality on a new home, distinguishing it from that of their neighbours,

According to Approved Document L1A (Work in new dwellings, 2006 edition) concerning energy efficiency which comes into effect in April, conservatories with a floor space not exceeding 30m2 are currently exempt from Building Regulations.  For those that exceed 30m2 ‘The performance of the dwelling should be assessed as if the conservatory was not there, which means that the thermal separation between dwelling and conservatory must be constructed to a standard comparable to the rest of the external envelope of the dwelling.’  However if the space is integral with the dwelling then it should be included as part of the new dwelling and should comply with criteria of Part L.

However, it is important to remember that state of the art glazing and ventilation features incorporated into the design, even for small conservatories, will make savings on the homeowner’s fuel bills, and this is a very good selling point.  Choosing the correct roof glazing for the aspect of the building can make a huge difference.  Both glass and polycarbonate are available in a combination of different thicknesses and finishes that have specific light and heat control benefits, and when used in conjunction with a suitable ventilation system, create pleasant surroundings. 

David Franklin of Franklin Conservatories describes the high specification ventilation and glazing incorporated into the design of a large conservatory built on luxury new homes in the grounds of a listed building.

“The roof of this large lean-to is glazed with Darby solar control bronze glass and incorporates Airscape thermostatically controlled roof vents with integral fly screens.  We have linked these, through a wall mounted control panel, to work in conjunction with Siegenia Aeropac air replacement units.  These work silently to provide fresh, active carbon filtered air and reduce humidity.  This set-up produces an efficient, cost-effective air conditioning system.    

“Under floor heating in each unit, run off newly installed boilers which are separate to those servicing the houses, ensures that the conservatory is an all-weather, high performance building.  To make sure we have built it to the optimum specification, we employed a heating consultant who has placed data capsules in each house to assess the energy saving benefits of the conservatory over a period of time.”

From the developer’s point of view, offering the choice of a conservatory to the buyer gives him the opportunity to differentiate his business and increase the desirability of his developments.  New homes complete with a conservatory have an air of exclusivity about them.

Palmer Market Research predicts a healthy development in conservatories supplied to the newbuild market after an initial dip in 2006.  Between 2004 and 2009 growth of 60.9% is forecast.  So how can fabricators take advantage of this potentially lucrative opportunity? 

The first step is to recognize the capabilities of the factory and workforce.  If your factory is already running at full capacity, you probably couldn’t handle the extra orders that a partnership with a builder would produce.  But if you have a skilled workforce that you employ elsewhere until a conservatory needs to be built, and have both floor space and machinery lying idle, then maybe now is the time to explore the prospect of joining forces.

Start by seeking out small and medium sized local developers and introducing your company to them.  Your roofing system supplier should be able to help you identify a list of prospects and target them with a direct mail campaign and follow-up phone calls to generate appointments.

Maybe they had never considered adding conservatories to their buildings because it all seemed so complicated, or perhaps a previous bad experience has left them feeling cautious.  This is your opportunity to build a relationship, to explain your offer and the market trends, and to reinforce the benefits to the builder of having a local, friendly and prompt supplier.  Being local, you are a person they can relate to rather than just a distant voice on the telephone, someone they can depend on for service and support.

You are experienced in all aspects of supplying the right conservatory for the job, so your strength in this partnership is that you can take care of everything from design to fabricating a high quality product.  Because you are local, you can deliver directly to site, just in time to suit the builder.  And you can offer installation training if required, as well as advice on glazing, ventilation and security options.

Remember – you are the conservatory expert and have a unique facility to offer.  So go on and sell yourself!

Based at Bagillt in North Wales, Quantal approved fabricator Ad Hoc has developed a thriving commercial and newbuild side to the business.  Director Ainsley Moorst explains how this has been achieved: “We have doubled the size of our roof build floor to cope with increased demand and offer a free conservatory design and consultation service.  All styles and finishes are purpose built to suit the individual needs of our customers. 

“Being local, we understand the specific requirements for conservatories in this area – our close proximity to the sea and our extreme weather conditions call for a product with superior strength and integrity.

“We enjoy great partnerships with a number of housebuilders, who really like the unique aesthetics and increased strength that the Quantal roof offers.  More frequently they are offering conservatories as an optional extra on exclusive newbuild developments and we can supply a high quality, stylish roof that keeps its good looks with minimum maintenance.  Everyone wins!”

When developers bought historic Moor Park near Harrogate for converting into luxury homes, they required a very special conservatory company to match their exacting standards.  David Franklin of Approved Quantal Installer Franklin Conservatories explains how the company undertook this unique installation.

Moor Park was based on Queen Victoria’s favourite residence, Osborne House on the Isle of Wight, which had been designed by her husband Albert in the style of an Italianate villa.  When it was acquired by developers for conversion into luxury apartments, stringent building and planning controls meant that any work carried out at the site had to match the quality of the existing buildings.  The work was completed to a very high standard by a specialist historic restoration company, including the construction of a terrace of three brand new properties adjacent to the original walled garden.   

The families that occupied these three houses approached Franklins with the idea of installing a single lean-to conservatory across the length of all the properties.  Initially we were concerned about taking on a project of this nature and size.  Each of the three families had different requirements, and we were concerned that if we upset one customer the danger would be that we upset them all!

The 45 metre long cream lean-to conservatory has a projection of four metres, made possible without a portal frame by using Quantal ‘Widespan’ glazing bars.  Proper walls, with heat insulation and sound proofing, have been constructed between each unit.  The windows were specially made using Franklin’s own unique system, which combines cream aluminium externally with ash on the inside.

Therefore the Quantal roof perfectly compliments our window system, with its strong external aluminium construction and elegant lines.  To match the cream windows, all the visible parts of the roof were spray baked in Quantal’s in-house paint shop using the latest, high-grade acrylic formulation and technology employed on modern car body work.  ‘Natural’ real timber finish internal cladding on the roof matches that inside the windows.

To maintain a comfortable temperature at all times, the roof is glazed with Darby solar control bronze glass.  Each unit has four BBA accredited Quantal thermostatically controlled roof vents with integral fly screens.  We have linked these, through a wall mounted control panel, to work in conjunction with Siegenia Aeropac air replacement units.  These work silently to provide fresh, active carbon filtered air and reduce humidity.  This set-up produces an efficient, cost-effective air conditioning system.     

Under floor heating in each unit, run off newly installed boilers which are separate to those servicing the houses, ensures that the conservatory is an all-weather, high performance building.  To make sure we have built it to the optimum specification, we employed a heating consultant who has placed data capsules in each house to assess the energy saving benefits of the conservatory over a period of time.

The 12-week build plan went without a hitch, helped by excellent regular communications between ourselves and the clients.  New software installed in the office enables us to record everything we discuss with the customers, and everyone here has access to that information.  The customers were pleased to receive regular emails informing them of our progress, and they, in return, could advise us of their concerns.  For example, it became apparent early on that they were very worried about having the lawns churned up by cement being delivered, so we hired a machine that pumped it to site and didn’t need to drive over the grass.  In fact, they were all so happy with the service they received from us that each has ordered a porch from us for the front of their buildings!

Originally a joinery company, Franklin was set up by my father Bob 30 years ago and is a real family business.  The unique window system, fabricated in our 10,000 sq ft factory in Yeadon near Leeds combines the best of both worlds with strong, high performance aluminium externally and the beauty of real timber internally.  Using with the Quantal roof, we produce very high specification, bespsoke conservatories and orangeries, and are particularly experienced in designing appropriate structures to enhance period and character houses.  We employ our own teams of professional craftsmen so that we can control every stage of installation and ensure the highest quality and instils total customer confidence.

On a trip to the UK, the production manager of rock giants Bon Jovi and Prince was very taken with the British idea of building a conservatory to bring the garden into the heart of the home, and thought that it would be a perfect addition to his house in Wisconsin.  While on tour in Minneapolis, he visited Approved Quantal Fabricator Trade Plas’ American showroom, ‘English Heritage’, and set about planning and designing an innovative conservatory to complement his country home.

The Quantal roof and aluminium windows where fabricated at Trade Plas’ Nailsworth factory, and transported with all the sealed units in a container to site in Wisconsin.  Once there, even though temperatures dropped to minus 30oC, work started immediately.

Measuring 4.9 m x 4.9 m, the conservatory is a conventional five-facet Victorian.  However, it is unusual because it has been constructed with a basement underneath.  The superb aesthetics of the polyester powder coated Quantal roof perfectly complement the attractive styling of the house, and it is glazed with self-cleaning, laminated glass.  The base of the conservatory was finished in stone cladding to match the house.

Richard Phelps, Production Manager for Trade Plas, explains: “The main concern with this installation was the extremes of weather it would endure.  Because the Quantal roof is all externally aluminium, it is strong enough to withstand the harsh conditions and it complies with strict local building regulations.

“The customer and his wife are delighted with the addition to what they call their ‘Gingerbread House’.”

Trade Plas operates a thriving business from its superb indoor showroom in Minneapolis.  The roof and windows for each conservatory are fabricated in its factory at Nailsworth by local craftsmen and shipped out, along with furniture, blinds and flooring if required, to the United States.  There they are installed by Trade Plas’ own fitting teams to ensure that the highest quality is maintained. 

As part of the flourishing Quantal Fabricator Network, Trade Plas enjoys the many benefits on offer to members, including technical and marketing support.  For further information visit www.quantal.co.uk or telephone 08700 110195.

Cheltenham based Approved Quantal Fabricator, Regent RS, fabricated and installed this stunning silver wrap-round lean-to conservatory on a new NHS administrative building in Yeovil, Somerset.

“The conservatory is used as a common room, and was built as part of a multi-million pound development by the NHS in this area” explains Andrew Genko, Managing Director of Regent.  “It measures 10 m by 9 m and was constructed using Quantal ‘Wide-span’ glazing bars, which enable lean-to conservatories of this size to be built without the need for portal frames.

“The roof was sprayed silver both internally and externally in Quantal’s in-house paint shop to match the windows, and the overall appearance of the installation is very high-tech and modern.

“The roof is glazed with 24 mm polycarbonate, and features automatic roof vents to keep the temperature in the extra space comfortable, even on the warmest days,” adds Andrew.

Sturdy ‘Wide-span’ glazing bars enable lean-to conservatories with a span of up to 4.2m to be built without the need for portal frames, purlins or tie bars.  Available in white, brown or oak as standard, ‘Wide-span’ can accept 24mm glass, 25 and 32 mm polycarbonate glazing.

Quantal fabricator Regent RS Group stepped into the breach when another company failed to deliver the goods during the enterprising conversion of a Georgian House to luxury retirement apartments.

The Cheltenham based firm was recommended to the site manager, who had already been waiting for six months. Regent fabricated and installed the two variable pitch lean-to roofs within days.

The traditional styling of the Quantal roofs, which feature a durable polyester powder coated aluminium external finish, complement the elegant building perfectly. The two conservatories have been installed on the first floor of the building, and open out onto patio areas, making them fantastic living areas for all seasons.

The oldest company in the Regent RS Group was established in 1984,and together they offer a wealth of industry experience. The group has recently invested £200,000 in the very latest machinery, plant and vehicles for its factory. The second phase of the development programme, a further investment of £50,000 is planned for next March.

Andrew Genko, Managing Director, comments, “By growing the business at a steady rate, we are ensuring its future. Through listening to, and communicating with, our customers we give quality service on a personal basis, to meet their individual needs.

“We offer a complete package from design to installation, including a full after-care service. Most of our work comes from the recommendation of satisfied customers. We have even fabricated the Quantal roof for clients over in Germany.”

This fabulous pool house belongs to a millionaire businessman in New Jersey, USA, and features a Quantal roof fabricated and installed by Nailsworth based company, Trade Plas.

The roof, 14.5 metres long and 8.5 metres wide, is glazed in bronze polycarbonate, while the lantern is in glass and features a different bespoke leaded design on each panel.

The Quantal conservatory roofing system was perfectly suited for this impressive project because of the strength of its aluminium construction, and its superior aesthetics.

The Quantal technical team calculated the measurements and design of the steel portal frame, which was fabricated in New Jersey. Then the entire roof and glazing were shipped to out to America from Trade Plas’ factory in Gloucestershire.

Trade Plas, part of the successful Quantal Approved Fabricator Network, have recently opened an impressive indoor conservatory showroom called ‘English Heritage’, in Minneapolis, USA.

The new structural lintel from Quantal Conservatory Roofing Systems proved indispensable when Bristol based Quantal approved fabricator, City Glass, installed a stunning, triple-aspect gable conservatory.

The conservatory, built on the side of a hill overlooking the Frome Valley, has added an elegant and spacious living area to the home, and has made the very best use of the space available.

The technical department at Quantal has developed the innovative profile, which enables adaptation of the strong existing box section eaves beam for use as a structural lintel. This greatly improves the integrity of the building, particularly where central doors are fitted.

Kevin Cole of City Glass explains, “The newly designed component from Quantal ensured we had a firm, level platform to fix the valleys into, and gave the entire structure great lateral rigidity.

“The position of existing doors and windows also meant that we had restricted working space. We overcame this problem by installing an intricate valley intersection making clever use of two wall plates against the house, enabling the conservatory windows and valleys to fit snugly right up to the house wall.

“Before commencing the actual installation, we carefully test built the roof raised off the ground at our factory to ensure that everything fitted exactly before moving it to site. This also meant that we could check it for water-tightness at this stage, too.

“The result is a delightful conservatory that the homeowners are thrilled with. They chose to have the roof glazed with glass so that they can enjoy panoramic views across the valley all day long, all the year round.”

City Glass was established in 1965, and has a huge client base in and around Bristol. The majority of their business comes from referrals and recommendations from satisfied customers, and they often now work for the third generations of original customers.

As members of the Approved Quantal Fabricator Network, City Glass can enjoy all the benefits that are on offer, including training, full technical backup and a comprehensive marketing package.

The BBA approved Quantal roofing system has a durable polyester powder-coated aluminium external finish, internally clad with PVC-U for thermal efficiency, and includes solid cast decorative cresting and finial. It is available in a choice of colours, with different glazing and ventilation options, and is low-maintenance for good looks that last.

Quantal fabricator, Trade Plas, installed this unique conservatory, perched high on the Cotswold Hills with beautiful, far-reaching views that can be enjoyed all year round, whatever the weather.

Richard Phelps, Production Manager at Trade Plas, explains, “The customer had a very clear vision of what he wanted when he visited our showroom in Nailsworth. We carried out his wishes down to the finest detail, and the result is this stunning and very unusual conservatory.

“The superior aesthetics of the cream powder-coated aluminium Quantal roof perfectly compliments the Roman-style Cotswold stone pillars, which were crafted locally to his exact specification. To further emphasise this feature, a light is sunk into the floor at the base of each pillar giving a spectacular display at night.

“The roof is glazed with Antisun and K-glass, to reduce glare on the brightest days. A high-efficiency air conditioning unit maintains a comfortable temperature in the conservatory during the summer, and under-floor heating keeps it cosy when it’s cold outside.

“As well as the conservatory, we also installed all the windows and doors, wardrobes, flooring, skirting and a staircase,” adds Richard.

The stylish good looks of the BBA approved Quantal system sets the roof far apart from any other system in the market. For more information on products or the fast-growing Quantal Approved Fabricator Network visit www.quantal.co.uk

Salisbury based Quantal Approved Installer Castlegate Windows has installed a fabulous conservatory for soccer hero, Nick Holmes, who played for Southampton Football Club when they won the FA Cup in 1976.

The externally powder coated aluminium roof of the 5-bay Victorian style conservatory is glazed with 25 mm heatguard polycarbonate, to ensure a comfortable living environment all year round.

Established four years ago by Managing Director Neville Beal, Castlegate is very much a family business, installing windows, doors and conservatories to trade customers right across central southern England.

The company recently moved to larger premises to cope with an increased volume of work. Neville explains, “I put the success of our business down to the fact that we always put our customers first, offering a complete turnkey conservatory package, from the initial plans right through to completion of the project.

“We offer top quality materials and ensure excellent workmanship by using our own teams of installers. Our customers prefer the unique Quantal roof for its pleasing traditional styling, its strength and its durability.”

Nick, who made over 500 professional appearances for the Saints, is now manager of Salisbury City Football Club, that plays in the Dr Martins Southern League. Neville is also a director of the Wiltshire team.

Large commercial conservatory installations could open up profitable opportunities for fabricators with sufficient resources. Steve Whistler, Technical Services Manager at Quantal Conservatory Roofing Systems, offers some pointers to look out for when considering a move into this lucrative area.

Hotels, schools, offices – all kinds of commercial concerns grow out of their premises, or just require extra, quality space for entertaining, working or relaxing. A conservatory can be the ideal solution, providing a new and different dimension to the existing premises, a light and airy haven away from the hustle and bustle of the main building.

Causing less disruption than conventional construction, a conservatory can be added to compliment and enhance the existing building and make the best possible use of available space. For example, a classic style can be added to an elegant hotel, affording a spacious extension to a dining room or lounge. But the clean lines would look equally good as the reception area or canteen of modern offices.

A conservatory is different from any other extension because of the nature of its roof. It is therefore essential that this crucial part of the building is robust enough to withstand the worst extremes of weather, year after year, whilst maintaining its good looks, and strong enough for these commercial projects, which tend to be much larger than domestic installations.

There are a few important considerations to be made before embarking on a large project. Fabrication and installation of large conservatories is very specialised, and it is vital that the venture is managed properly, and that the appropriate know-how is available to see it through to completion. One roof could take up the entire space in a factory, as well as requiring extra manpower and time, and it may take several installation teams. A word to the wise here: a substantial proportion of cash could be tied up in just one venture. But if all these issues can be addressed there are significant opportunities for forward-thinking fabricators.

Roofing systems and Portals
For optimum long-term performance, an external aluminium roofing system will best fulfil all these criteria. Box section aluminium eaves beams and box gutters will allow for larger roofs without the need for tie bars. However, the use of a portal frame system enables very large conservatories to be built, offering countless design possibilities.

In these cases, a structural engineer must be consulted at the start of a project, and he will make a full report based on the locality and intended use of the proposed conservatory. By understanding the needs and aesthetics required, calculations are made which will determine the size and material of the components of the portal. Aluminium is lighter and easier to handle, but the beams may need to be thicker to incorporate enough strength. Steel is much heavier and stronger, and could require lifting with a crane, but the beams needn’t be as thick. Either material can either be powder-coated before installation, or painted or clad with PVC-U when construction is complete.

Ventilation and Glazing
Adequate ventilation and appropriate glazing are just as important in a large commercial conservatory as in a small domestic one. For simple ventilation, manual or electric roof vents are available, and can also be supplied with thermostatic and rain sensor options. More active ventilation can be facilitated with the installation of an electric extraction, air conditioning or air exchange unit to prevent heat build up and refresh the air.

Many glazing options are available for the roof, and the most suitable choice depends on the aspect of the conservatory and how it is to be used, as does the need for blinds. Glass must be either 4 mm toughened, which is lighter and therefore easier to handle, or 6.4 mm laminated, ideal for bigger spans, but heavier. Polycarbonate sheets are lightweight and therefore more manageable, and come in a variety of finishes, including clear, bronze and opal, which can offer excellent insulation and reduce glare and heat build up in the conservatory. For installations that may be difficult to reach, self-cleaning glass could be the perfect solution.

Finishing touches
And to look good on the outside, polyester powder coating is hard to beat. Used on most modern shops and offices, this highly durable finish is resistant to grime and can be restored to its original sheen with just a quick hose down. Another advantage is that it ensures visually consistent colour over the whole of the roof.

An Edwardian Conservatory measuring 30 metres by 12 metres was installed at Tameside College. It was built for use as an extension to the college’s canteen, and offers a light and spacious area for students to relax between lectures.

The caramel coloured Quantal roof is supported by a steel portal frame, and glazed with 25 mm bronze polycarbonate. Siegenia Aerostar Classic ventilation units have been installed in the roof to ensure that comfortable conditions are maintained in the room below.

The roof and light oak foiled Profile 22 windows for the conservatory were fabricated by a local Approved Quantal fabricator.

Managing Director of the company explains, “We secured this contract on the recommendation of a satisfied customer. It is by far the largest project we have undertaken, but we are very pleased with the result – and so is the college.”

A Devonshire public house chose blue Anti-Sun glass for the glazing in the roof of its restaurant conservatory extension. The aluminium Quantal roof was strong enough to need just tie-bars rather than a portal structure. The result feels spacious and airy, like a continental bistro, even during typical British weather.

The technical team at Quantal Conservatory Roofing Systems has many years’ experience producing calculations and working with structural engineers and a specialist portal frame company. By working closely with fabricators, advice can be offered on both construction and project management of commercial conservatories.

The Quantal system is polyester powder coated aluminium, internally clad with PVC-U for thermal efficiency. It’s strength and durability makes it ideal for commercial installations and it has good looks that will last.

This conservatory was designed and built by Nailsworth based Quantal Approved Fabricator Trade Plas, and won the Conventional Domestic category of the Glassex 2004 Conservatory Design Competition

The bespoke-built Cotswold stone house on a private estate in Gloucestershire had an enclosed space between the kitchen and a garden wall ideal for a conservatory.

Richard Phelps, Production Manager at Trade Plas, explains, “The homeowners had approached many conservatory companies who had suggested Victorian or Edwardian PVC-U styles, which would have looked out of place in this situation. The couple wanted a conservatory to compliment and enhance their home and make the best possible use of the space available.

“We showed them a selection of pictures of bespoke installations in various styles and finishes that our company had completed, and from these they were able to form an idea for a design of their own.”

The double aspect gable roof is fabricated from the Quantal roofing system, and has a dual colour polyester powder coated aluminium finish, charcoal grey externally and cream internally. ‘Sunburst’ Georgian Bar designs feature on each gable. Solid cast aluminium cresting and finials give an authentic and aesthetically pleasing appearance to the roof.

The roof features two BBA approved Quantal roof vents, and is glazed grey anti-sun self-cleaning glass. The conservatory also has an air conditioning unit, to maintain a comfortable living environment all year round.

To really give the feeling of bringing the garden into the heart of the home, the front has a generous 3.1 metre opening with bi-folding doors. This is made possible by the use of the innovative Quantal structural gable lintel, which gives the entire conservatory great lateral rigidity.

Matching dual colour, square leaded, aluminium windows complement the Quantal roof perfectly, and the result is a fabulous conservatory, completely in keeping with the character of the house, which the homeowners are truly delighted with.

The stylish good looks of the BBA approved Quantal system sets the roof far apart from any other system in the market. For more information on products or the fast-growing Quantal Approved Fabricator Network visit www.quantal.co.uk or telephone 01626 836403.

This attractive Edwardian conservatory was fitted by Leicester based Quantal Approved Installer Magna Windows.

Managing Director of Magna, Brian Cheshire, explains, “The homeowner was keen to replace the existing old wooden lean-to with a structure that would be in keeping with the traditional appearance of the property whilst offering all the benefits of modern materials.

“The external aluminium Quantal roof is ideal for this project because it is so strong and the polyester powder coated finish will keep its brilliant white appearance for many years with minimal maintenance.

“The conservatory is south facing, so the roof is glazed with 24 mm heat reflecting glass, which will help to maintain a comfortable environment even on the brightest days.

“In addition to the conservatory, Magna Windows has replaced all the windows and roofline on this property with high specification, low-maintenance products. The homeowner is delighted with the results,” concludes Brian.

Magna Windows is part of the flourishing Approved Quantal Retail Network. For further information on products and services visit www.quantal.co.uk or telephone 01626 832355.

Diners at an exclusive hotel on the English Riviera can now enjoy panoramic sea views thanks to the addition of a new conservatory featuring a roof from Quantal Conservatory Roofing Systems.

The lean-to conservatory on the Redcliffe Hotel, Paignton, extends along the length of the dining room. It measures 18.5 metres by 3 metres, and features Profile 22 windows and two sets of double French doors, which also serve as fire escape doors. A leaded design in the fan lights complements the windows in the rest of the hotel, and was a planning requirement.

The roof is glazed with 24mm Argon filled, toughened glass units, to improve the thermal efficiency of the conservatory. In addition, a new air conditioning unit situated in the adjoining dining room will help to maintain a comfortable environment for guests.

To comply with local building regulations, a portal frame was incorporated in the construction of the structure. Special reinforced concrete pads were made to transfer the load from the portal to the footings.

Hotel Manager, Stephen Twigger, explains, “Not only have we considerably increased the capacity of our dining room by installing this conservatory, we have also created a stylish area with fabulous views along the entire Torbay coastline that opens directly onto our waterfront gardens.

“Window seats in the restaurant are going to be even more in demand,” adds Stephen.

Quantal Approved Installer Castlegate Windows had to overcome 20 inch thick wattle and daub walls and the inclement British weather when they installed a conservatory on a 200-year-old cottage.

“It had always been the homeowner’s dream to extend her home to provide much needed room for entertaining,” explains Castlegate’s Sales Director, Craig McIndoe. “We were recommended to her by another satisfied customer, and we were pleased to accept the challenge of providing her with a conservatory that would compliment the character of the building, whilst fulfilling her criteria.

“The traditional styling of the Quantal roof fitted the bill perfectly and our customer is thrilled with the result.

“However, the job was not straightforward. We had to cut through the thick wattle and daub cottage walls, taking great care not to allow them to get wet – a real dilemma during one of the wettest summers on record!

“And so the upper windows can be reached, we incorporated a manual Quantal roof vent, which is BBA approved and can be unhinged from inside to provide access for cleaning and maintenance.

“Now the delighted homeowner has the space she wanted, bringing her garden right into the heart of her home to enjoy with her friends throughout the year, whatever the weather,” continues Craig.

Castlegate Windows is very much a family business, installing windows, doors and conservatories to customers right across central southern England. Established five years ago, the company has gone from strength to strength, and recently moved to larger premises to cope with an increased volume of work.

“I put the success of our business down to the fact that we always put our customers first, and offer a complete turnkey conservatory package,” adds Craig.

As part of the flourishing Quantal Retail Network, Castlegate enjoys the many benefits on offer to members, including comprehensive operational, sales and marketing support using Quantal’s tried and tested expertise and a variety of initiatives to help them sell the Quantal difference and convert more leads into sales.
