New Black & White Guides to U-Values for England, Scotland, and Wales

October 21, 2022

After the success of our Black & White guide to window U-Values launched at this year’s FIT Show, we have created a version for Scotland and Wales to prepare for the imminent Building Regulation changes expected to take place later this year. The original guide, created in response to changes to the regulations in England, has also been revised to ensure that all our customers have the most up to date information at their fingertips. 

An industry first, our first guide was launched at this year’s FIT Show and gave clear and concise information on how all VEKA’s window systems can meet a U-value of 1.2 W/m2K. This was in response to updated Building Regulations that came into force in June.   

The new regulations in Scotland that come into force in December will also require a 1.2 U-Value, whilst in Wales it will be 1.3 from November.   

Differing calculation methods across the 3 countries are causing confusion for fabricators, but we are committed to supporting our customers in navigating these.   

The specifications in the new suite of guides are country specific, fully reinforced, and realistic to fabricate. There are no grey areas or hidden small print and they apply to both light and dark colours. 

Both guides include detailed drawings of chambers and reinforcements and are available to be downloaded from our website below, please find the links below:
