Our bow and bay windows require very little upkeep to look their best. With this, you won’t be spending excess periods of time wiping your windows clean for them to look their best. Despite this, they’ll remain secure and fully weatherproof for the years to come.
uPVC, which is used for the framework, is famed for its lifespan and low maintenance. It only needs an occasional wipe down, with particular attention on the moving components. Fade proof technology means you’ll never need to varnish your chosen coloured foil.
A multi chambered profile and modern double glazing allow our bow and bay windows to offer excellent thermal efficiency. They’ll retain the maximum amount of heat within your Newbury or Berkshire home, allowing for year round comfort and modestly priced energy bills.
With bow and bay profiles often being wider and consisting of multiple window profiles, it’s imperative that they are achieving such excellent thermal retention. They’ll prevent the ingress of cold air, keeping your home at the optimal temperature, even during winter.
Our bow and bay windows offer a reassuring level of home security. We go above and beyond to ensure that all our windows keep you and your family safe at night. You’re protected by some of the industry’s leading multipoint locking systems.
There is also a range of security upgrades available with our bow and bay windows. Among these are the options for SAC security shootbolts and security dog bolts. With certain upgrades, our bow and bay windows can reach Secured by Design certification.
