Energy Saving Windows and Doors - A Better Choice for Your Home

Modern double glazing doesn’t just look good. It can save you money too. From styling to performance to saving energy, our advanced glazing technologies are engineered to give you a comfortable, secure, quiet, energy efficient home.

Reduce wasted energy and cut bills

Choosing energy efficient windows, doors and conservatories to replace single glazed or older double glazed units saves energy from day one. In fact, replacing the windows alone could reduce your heating costs by up to 20% - perhaps worth up to £321 a year*.

Choose better looking frames

Clear, uncluttered sightlines ensure windows look well proportioned, elegant and attractive. Features like our low sightline Q-Lon weatherseal ensure performance and style with savings.

Reduce condensation and noise

Lowering heat loss at glass edges can cut window, external door and conservatory condensation by up to 80%. Glass units and our high performance Q-Lon gasket helps reduce noise pollution over a wider temperature range, too.

Using less energy means less CO2

Science suggests man-made emissions play a major role in global warming and, in turn, influence climate change. Home energy use alone accounts for 27% of UK carbon dioxide (CO2) emissions which contribute to climate change.

The Glass and Glazing Federation calculates that if all UK replacement windows installed were B and C rated instead of the minimum building regulation specification, each household could save the energy equivalent to making 34,000 cups of tea!

Our windows make more of ambient heat

In winter, the energy efficient coated glass used in our windows retains warmth within the home. It’s also designed to exploit radiant heat energy from the sun. These properties result in significant fuel savings compared to a single glazed dwelling.

Above: The images show just how effective fitting energy efficient windows to your property can be. The right hand side of the property still has the original windows – the reds and pinks show heat escaping. However, the new extension on the left is fitted with energy efficient windows, the lack of reds and pinks proving they help dramatically reduce heat loss.
