European Aluminium, based in Brussels, was founded in 1981 and is the voice for the aluminium industry in Europe.
This association has developed an excellent short video, How to assess the thermal performance of windows, which can be seen below:
The BBSA is pleased to see European Aluminium make a strong case for considering summer solar gains as well as winter heat loss in any building evaluation – what’s known as energy balance. This is important, given that many modern homes are prone to overheating.
We note with interest the statement in the video:
“…for optimal energy balances all year round, openable windows with adaptable shades, are a must.”
