Energy Efficient & Thermally Insulated Windows

Our UPVC and aluminium windows are specifically engineered to keep your home warm in the winter and cool in the summer.

Energy efficiency - built in...

Our windows are specifically designed for the inclement British weather. Our UPVC windows feature 14 built in chambers to provide supreme thermal performance. They also feature dual density weather seals for long lasting airtight protection and added noise protection.

Our modern aluminium window ranges feature thick polyamide thermal barriers, keeping the cold out and heat in. These built in warm barriers allow us to keep frame width to a minimum, allowing more light into your home without compromising the energy efficiency of the windows.

Saving you money…

It goes without saying that the more heat you stop escaping from your home, the less it will cost you to heat it. Our energy efficient windows actually reflect heat back into the room by using clever ‘soft coat’ glass as standard. Gone are the days of your windows creating cold spots in the room. The glass we use stops the warmth bridging the gap between the panes, keeping the inside glass pane far warmer than ever before.

With rising energy costs one of the most difficult challenges facing us and our families today, one of the first things you should do is make your home more efficient by upgrading to Joedan windows.

Warm in the winter, cool in the summer

Windows only 15 years old are now far less efficient than today’s systems. Through changes in building regulations, modern windows feature warm frame technology. The glass panes are separated by warm-edge spacer bars to stop thermal transfer. The upvc windows have many more chambers built in to stop cold bridging. And our aluminium features the highest performing thermal barriers ever seen.

All of these technologies ensure your home remains cosy whatever the weather. Our windows will reduce cold zones and condensation, whilst regulating solar gain for your comfort throughout the seasons.

Low U-Values

U-values measure how effective a material is as an insulator and our replacement windows have incredibly low U-values – the lower the U-value, the greater the level of thermal insulation offered. They hold in heat tight to stop rooms going cold and you having to compensate by cranking up your thermostat, costing you in energy.

Our UPVC Portofino and Aluminium Lusso window profiles have the finest insulation properties and are a protective barrier against the weather that you can depend on whatever the external temperature is.
