Chesterfield Community Centre – Bespoke Entrance Canopy

At Clovis Canopies we use polycarbonate roofing as although slightly more expensive, we find it has a better combination of strength, impact resistance, sheet size and colour, fire / flame resistance and longevity of life than any of the other above mentioned cheaper materials.

We use a two part glazing bar on our canopies with rubber gasket or cushions to attach the roof polycarbonate sheets as this allows for the expansion of the sheets as the weather heats up or cools down. The rubber gaskets as well as creating a watertight seal greatly reduce noise levels as the sheets expand and contract. We do not screw sheets directly to the framework as this can lead to the roofing sheets buckling and potentially causing leaks due to the possibility of screw heads popping off. In addition to this we never lap one sheet over the other as this can result in an algae build-up resulting in unsightly discoloured patches in the roof.

In relation to our canopies Building Regulations specify the standard to which they should be built i.e. strength, fire rating of materials etc. Again it is advisable to contact your local Building Control officer(s), as a rule of thumb any canopy over 30m2 will require conformity to building regulations and an application will need to be made although this figure can be lower. Most of our structures are supplied conforming to the requirements for these regulations as standard and generic sets of structural calculations can be supplied free of charge to demonstrate to Building Control the integrity of the proposed structure and foundations.
