uPVC windows exceed expectations with a light yet sturdy frame, used in conjunction with various locking combinations. Installed alongside double or triple glazed panes of glass, these profiles adhere to PAS24 regulations.

Low Maintenance

uPVC windows need very little upkeep to stay looking their best. They retain their shape in all weather conditions without the need to excessively maintain them. Simply use a cloth to clean the components and keep them dust free.


uPVC is an incredibly tough material and can cope against the most extreme elements, including rot and corrosion. Our windows are coated to ensure they are protected against UV rays, stopping the material fading in prolonged sun exposure.

Thermally Efficient uPVC Windows

We work with Profile 22 to supply high quality uPVC window profiles to tradesmen and homeowners. These windows are some of the most thermally efficient on the market, giving homeowners a comfortable home all year round no matter the weather.

They achieve this thanks to a five chamber sash and six chamber outer frame. The slim profile of the uPVC windows we supply allows for a larger glazing area. This will help improve thermal efficiency and offer panoramic views outside of the property, letting more natural light enter the building.

Not just thermally efficient, our uPVC windows come with seals and gaskets to keep out draughts and stop rainwater from seeping into the home. The deeper channels within the frame help with drainage, leaving the window and the building free from mould. Keep any building warm and dry when using the windows we supply, plus help lower maintenance and energy costs.
