Energy Efficiency

Energy Saving Trust

The Energy Saving Trust is an organisation dedicated to the promotion of energy efficiency. Our industry leading uPVC windows are certified by the Energy Saving Trust and every Duraflex product we install proudly displays the Energy Saving Trust recommended logo.


Our Duraflex products are endorsed by leading energy specialists, the BFRC who measure all components of a window for energy efficiency. Our A+ energy rated windows proudly carry the BFRC seal of approval, giving you incredible energy performance.

Window Energy Ratings

Energy ratings provide you with an indication to a product's overall energy performance. The higher the energy rating, the more energy efficient the window is. Now you can see just how impressive our A+ energy rated windows really are.

Thermal Efficiency

All of our uPVC Duraflex windows and doors contain innovative technology which allows you to gain free solar heat energy. Offering superior thermal efficiency, our Duraflex double glazing combines a revolutionary multi-chambered profile with market leading glazing.

How green is your home? Is your property efficient? Your home’s efficiency is important, especially in these eco-conscious times.  Maintaining a high level of efficiency is an effective way to reduce your monthly outgoings too. Energy efficient windows and doors can help you save precious and valuable energy. When was the last time you checked your current windows for draughts?

Save Energy. Save On Bills.

When it comes to conserving energy it's simple. Save on energy and save on money. Maintaining a good level of home efficiency will really help you to save on those pennies and pounds. A well-insulated home will not only contribute towards a greener environment but has the added benefit of protecting your wallet too.

Our energy efficient Duraflex windows will help save you money on your heating bills by retaining warmth and reducing the amount of energy needed to heat your home. A glass metallic coating successfully works to reflect heat back inside your property. How clever is that?
