casement window design is a traditional window pattern where both casement and
frame sit flush with each other. Our high performance casement window
incorporates the latest advances in glazing, hardware, and draught seals. It still however
retains a traditional appearance, making it ideally suited to conservation
areas, listed buildings and new build properties.
Night vent opening
This is a feature of our casement windows which allows them to be secured in a slightly open ‘vented’ position. This offers obvious security benefits, and also in some cases it can be acceptable as an alternative to trickle vents in providing background ventilation to the room.
Our standard double glazed specification is a 24mm thick unit (Centre pane Ug Value 1.2) which achieves a ‘whole window’ U(w) value of 1.5. The unit comprises of: Low E Soft coat inner glass: 16mm cavity, Argon gas filled and warmedge spacer bars. Low iron glass outer leaf. Our standard triple glazed specification is a 36mm thick unit (Centre pane Ug Value 0.7) which achieves a ‘whole window’ U(w) value of 0.95. The unit comprises of: Low E soft coat glass for the 2x inner leaves. 2 x 12mm cavities, Argon gas filled and warmedge spacer bars. Low iron glass outer leaf. We use toughened safety glass as a standard for all windows which offers added security. For particularly noisy environments, we use an acoustic laminated glass for the outer leaf to provide improved sound insulation. In certain historic or listed building applications we use slimlight double glazing as thin as 11mm thick.
