Thermally Efficient Designs

The bow & bay windows we supply to tradesmen and homeowners come with a multi chambered profile as standard. This will hugely improve the insulation that these windows offer and improve the general thermal efficiency of any building. When partnered with our double glazing, homes will feel naturally warmer and retain more heating during the colder winter months.

Over time this will help homeowners save money on their energy bills and keep their property comfortable all year round. We also offer double and triple glazing replacement services, if the bow and bay window framework is still up to scratch.

Other thermally efficient features within these bow & bay windows include a weather seal flipper and glazing pad for an improved seal. The wide drainage channel reduces water ingress residue, helping minimise leaks and damp. Our bow & bay windows are made from uPVC, which is a hard wearing and extremely durable material. The weatherproof profile used in your installation will also prevent wind and rain entering, so any home will be warm and condensation free.
