Bay & bow windows will add space and depth to your Wiltshire or Oxfordshire home.

Bay and bow windows have so much character to them and that character will massively enhance the personality of your house once they’re fitted. Because of how they almost reach outwards, they’ll be more fully exposed to the sun, making them incredibly energy efficient.

Whether you have a traditional aesthetic or a modern style we can create the right bay & bow windows for your home using our remarkable replacement windows. If you’re currently living with draughty windows, you’ll be amazed at the difference when you upgrade.

Grey UPVC Bay & Bow Windows

We have the capability to fashion bay and bow windows in all manner of shapes and there’s all sorts of colours that can be assimilated into the frames. A bay window is on a par with a casement window when it comes to thermal efficiency, so expect it to keep the inside of your house well insulated day in, day out.

These heavy duty and highly engineered hinges offer increased load bearing. Featuring anti-crowbar technology, they promise a lifetime of performance.

Extreme Locking

With up to 9 locking points and two high compression hinge bolts, you get 360-degree solidity. Upgrade to Secured by Design if you want the lock to meet the Police-approved standard and be further assured of safety.

Extreme Frame

An EXTREME frame is made up of a total of 14 chambers (combined sash and frame) to deliver exceptional thermal performance. This also makes it twist and age-resistant, stopping your windows from ever losing their appearance.

Extreme Handles

Make your energy costs so much cheaper...

The worldwide energy crisis is hitting homeowners the hardest and it makes it crucial that your property is energy efficient. It will be once you have your old windows removed and exchanged for our EXTREME UPVC windows.

Far less heat will escape from the place and you won’t feel the draughts that previously filled it. They will make it warmer and at the same time, let you reduce your energy usage.
