As the market becomes increasingly aware of the implications of Window Energy Ratings (WER), so the level of confusion and need for precise explanatory information has risen.

Conscious of the need for clarity of understanding WER, and to ensure fabricators are as well informed as possible, WHS Halo has prepared a WER ‘Ready Reckoner’ as part of its In Business Together business and technical support programme.

The Reckoner provides a simple schematic overview of the elements that need to be taken into consideration and the practical steps required to actually prepare for WER submission. These are supported by detailed yet straightforward, guidance notes on a host of relevant topics from Quality Management Systems and frame and glass specifications to air leakage testing and certified simulation agencies.

WHS Halo is a Certified Simulator in its own right and members of its In Business Together programme receive WER calculations free of charge – a saving of up to £800 per window compared to those from independent consultants.
