Section 6 for Scotland

The Scottish Government has released new versions of the domestic and non-domestic Technical Handbooks in support of the Building (Scotland) Amendments Regulations 2010, coming into force on 1st October 2010.  New buildings will have to be at least 30% more efficient than current new buildings.

For replacement windows, the requirements for Window Energy Ratings and window U values have been tightened.  Severe restrictions are placed on the centre pane U value compliance route. The benefit of supplementing existing single glazing with secondary glazing has also been recognised.  Energy efficient glazing such as Pilkington K Glass™ and Pilkington energiKare™ are well placed to satisfy these requirements.

For non-dwellings, there is a greater focus on limiting solar gains in the summer, increasing opportunities for high performance solar control glass such as Pilkington Suncool™, Pilkington Eclipse Advantage™ and Pilkington Solar E™.

Bulletin 11 summarises the changes which are relevant to glazing and come into force on 1st October 2010.
