Our Stunning uPVC Windows
Sometimes you just have to say enough is enough with your old wooden or dated uPVC windows.
It’s like saying goodbye to your clothes from 10 or 20 years ago. You wouldn’t dress yourself in 20 year old clothes, so why keep your home dressed in 20 year old windows? It’s time to freshen up, and there’s never been a better time to do it.

- A-Rated levels of energy efficiency, with triple glazing potential
- Certified to BS7412, BS7413, PAS023, PAS024, and BS7950 (Rehau only have the latter two)
- Engineered using O70 Gold, a uPVC system that’s highly recyclable
- Slimline sculptured frames for a superior finish
In addition, all our windows are expertly fit using our trademarked SmartFit™ method, which means they are fully air-sealed during installation to ensure they are able to protect your home against draughts and water leakage, boasting impressive storm proof capabilities.
We’re also proud to boast that all our uPVC windows exceed the government security standards, so you can have complete peace of mind in their performance.
