Energy efficient ‘A’ Rated Windows

A high-quality uPVC frame will help to drastically lower heating bills and increase the overall value of your home. We work to deliver a truly groundbreaking uPVC profile.

Triple Glazing

Most UK window systems are not designed for triple glazing. Consequently, installers are forced to fit a much thicker triple glazed unit into a profile designed to take a 28mm unit! The result is that fitters struggle to bead windows, with the units being forced under such pressure they fail, with expensive service calls virtually guaranteed.

Did you know that over 20% of all heat loss escapes through your windows, even if they are double glazed? You can now make significant savings by switching to our innovative C2C insulating glass.

We offer quick and easy installation, as an entire window replacement is not required. By just replacing the glass, you can benefit from a warmer house, as well as the added benefit of cheaper gas or electricity bills.

Over 20% of all heat loss escapes through your window

What is insulating glass?

Our C2C insulating glass considerably reduces the heat lost through your window space, making it three times more efficient than ordinary window panes and over twice the efficiency of normal double glazing.

Many of the major energy companies have announced that prices will continue to rise for both electricity and gas throughout the coming years, with some, even showing increases of 28 %, as tariffs change. We think it’s important to provide a small solution for our customers to aid with their energy bills and the rises.

Even with loft and cavity wall insulation, you could still be losing over 20% of your heat through your glass.

Insulating glass not only helps with reducing your heat loss but also with issues such as conservatories overheating in the summer or being too cold in the winter. Our insulating glass can help regulate temperatures, allowing you to enjoy your conservatory to the fullest.

100% Recyclable

Our uPVC windows hold fantastic energy saving values, without the use of harmful materials such as lead and steel. This makes our uPVC frames kinder to the environment, as well as being 100% recyclable.

Tough wearing

As a material, uPVC is an incredibly energy efficient, exceptionally workable and tough! Our patented design comes complete with glazing flippers and thermal dams to help minimise cold air ingress and prevent water leaking through.

Multi Chambered

The intelligent frame is constructed from a series of size optimised chambers. These chambers trap pockets of warm air, creating a thermal barrier within the frame. This prevents the cold air from transferring into the property.
