Orangery Roof Construction

Orangeries in a few simple steps

At Quantal we have redesigned the traditional timber orangery flat roof system in a simple modular form to make on-site assembly quick and easy.


3 Stages of Construction

Step 1 1. The 4 modular cassettes are manufactured to your bespoke requirements and delivered complete and ready to install
Step 2 2. The modular design allows quick and easy on site construction
Step 3 3. Once installation is complete any suitable waterproof covering material can be applied to weatherproof the complete roof system
