Triple glazing: the way forward

21° has recently made the decision to switch over to triple glazing for all its standard window specifications.  With the prices of our triple glazed timber windows at only around 10% more than the double glazed alternative, triple glazing is becoming more affordable than ever.  For a small additional extra investment it is possible to radically improve the comfort and energy efficiency of homes and buildings. If you are going to the hassle of installing new windows and doors, we would strongly recommend that you take advantage of the extra benefits that triple glazing offers.

According to the Energy Saving Trust, windows contribute to 26% of domestic heat loss. Triple glazing can be up to 50% more thermally efficient than double glazing, saving energy and reducing CO2 emissions.  Triple glazing increases the comfort of buildings by raising the surface temperature on the inner pane of glass, eliminating cold spots and draughts near windows,. Triple glazed windows are already commonplace in countries such as Germany and Austria where low energy buildings and Passivhaus design are encouraged. As homes get more insulated and airtight the performance of windows and doors becomes even more critical.

21° believes that triple glazing should become the standard choice for windows and doors in the UK, as part of urgent action to reduce CO2 emissions from buildings and to help combat climate change. Windows and doors installed in 2015 could still be around long after 2050, so it is important that they are as thermally efficient as possible. In order to fight climate change we need to radically improve energy efficiency standards in UK buildings. Triple glazed windows and doors will be the only correct specification to complement these necessary super insulation measures.

21°’s window ranges offer whole window U values as low as 0.68 W/m2/K, far in advance of current building regulations
