Keston Dual Pitch Canopy
The Keston is a polycarbonate dual -pitched canopy purpose designed for the public market, this is not a lightweight domestic canopy designed for the patio. Using structural steel sections large uninterrupted spans can safely be achieved.
The Keston is a polycarbonate mono-pitched canopy purpose designed for the public market, this is not a lightweight domestic canopy designed for the patio. Using structural steel sections large uninterrupted spans can safely be achieved. The lean-to format can be used to butt up to existing walls or over sail existing roofs and gutters without creating an additional roof valley.

Frequently Asked Questions
- Do you fix your canopies directly onto tarmac?
No, all canopies are fixed on to concrete pads or bases as the structures can lift out from the ground if not fixed into a suitable concrete base due to the uplift created by wind acting on the roof area.
- Do you use Polycarbonate, PETG, GRP or Acrylic for non fabric cladding?
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.
- How are the fabric sheets attached to the framework?
Fabric sheets are securely attached all round using an aluminium cladding rail system, which has been tried, tested and proven for over 30 years.
- 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.
