| With extensive areas of glazing,
conservatories attract large amounts of the suns radiation,
which can create internal heat build-up, often with
high humidity levels on warm days and may result in
condensation on cooler days. Ventilation is therefore
absolutely vital in any conservatory to ensure a comfortable
environment.
This leaflet describes some of the most popular options
currently available. Your installer will be able to
answer any queries and provide costs for any of the
options.
Your primary decision will be whether to opt for Roof
Vents, Fans, Extraction or Air Exchange. |

The simplest and most economic method
of ventilation is the opening roof vent; a rectangular, top
hinged glazed unit, fitted within a roof panel. These attractive
and proven units are water and draught proof and may be operated
manually or electrically.
Uses a lightweight pole with a manual
crank handle at the lower end and a hook at the top which opens
or closes the vent. Stored away when not required, it avoids
the need for a fixed operating mechanism.
A traditional fixed manual mechanism,
comprising a winding handle control box linked by flexible rod
to an opening device mounted on the vent.
An electric motor unit is attached to
the vent, controlled by either; a wall-mounted switch, or an
infra-red remote control unit. Multi-vent, rain sensor and thermostatic
versions are available.

Although not strictly ventilation,
a stylish, quiet running ceiling fan is a valuable asset
to a conservatory environment. In summer it provides an
excellent down-draught cooling effect which can reduce
the temperature by up to 5° and reduce air conditioning
costs by up to 40%. In winter, by reversing the fan direction,
warmer air trapped in the roof can be re-circulated to
reduce heating costs by up to 10%. There is a wide range
of designs available; including combined light fitments,
multiple speed and infra-red remote control. |

The Siegenia ‘AEROSTAR Classic’
is an example of a popular ventilation extractor unit. It rapidly
reduces temperature and humidity levels by extracting up to
280 cubic metres of air per hour. Quiet in operation and unobtrusive
in appearance, this powerful unit is externally mounted in a
roof panel. Control is via a basic switch panel, or a combined
electronic humidity and temperature control unit. It can also
be linked to a rain-sensor allowing automatic shut-down and
sealing of the exit louvers.
Combitronic - Combined
electronic, humidity and Temperature control unit
An efficient ventilation system that simultaneously
removes stale air and replaces it with fresh; The Segenia
AEROPLUS provides ventilation and humidity control with heat
recovery. It is an energy saving method that recovers and
re circulates up to 60% of the heat from the extracted air,
while replacing it with up to 30 cubic metres of fresh air
an hour.
This environmentally friendly unit can also remove nearly
6 litres of water per day. Particularly beneficial in a conservatory
with high humidity, it is mounted on an external wall and
controlled manually or automatically.

IMPORTANT:-
To ensure the efficiency of any ventilation system, there must
be a constant source through which fresh air can be drawn into
the building, either from a door, side window or air brick etc.
