Why Passive?

There is increasing regulatory pressure on architects, builders, contractors and developers to improve the thermal efficiency of buildings, culminating in the Government’s target of Zero Carbon for new dwellings by 2016. Installing passive windows and doors is a major factor in improving energy efficiency.

In line with the performance requirements set down by the PassivHaus Institute in Germany and the upper levels of the Code for Sustainable Homes, Passive Windows’ products provide U-values of 0.8W/m2K for the glass and frame combined (not just the centre pane), with solar heat gains of over 50%. 

Further underlining Passive Windows’ environmentally sound credentials, all timber used in production is from sustainable sources, independently certified by BM TRADA to FSC or PEFC chain of custody standards.
