Watford Grammar School for Boys – Entrance Canopy
This modern Keston Cantilever entrance canopy was procured by the school as a replacement for an existing canopy that had become a little ‘tired’. One key reason the school chose this style was because of the cantilever design which removed the need for two support posts on the existing canopy that were placed in the middle of a circulation area.
The new canopy measures 3.5m deep x 3.8m long and is clad with opal multiwall polycarbonate laid into glazing bars, which looks similar to, and has the same effect as ‘frosted’ glass. The structure and RWGs were polyester powder coated to the required RAL colour. Reinstatement around the support posts was completed by others.
This new Keston looks impressive with its size and will serve the newly refurbished school building for many years to come.

Frequently Asked Questions
- Will I require planning permission?
We always advise that you call your local planning authority as there are no hard and fast rules. They will advise on whether you require planning permission for your proposed canopy. Although it differs from region to region canopies under 30m2 may not require permission but this can be affected by situations such as proximity to neighbours, listed building status, conservation areas etc. so it always best to check. We are happy to provide free of charge, scaled drawings etc. of the proposed canopy structure to assist your application should you require.
- Will there be any additional hidden charges to the quotation?
No, our prices are all inclusive.
- How is the polycarbonate sheeting attached to the framework?
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.
- What are Building Regulations and will they affect me?
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.
