The British Woodworking Federation (BWF) has re-launched its basic U-value calculation service to bring it in line with the Construction Products Regulation (CPR).
Under the CPR, which was introduced in July last year, all businesses with a staff or ten or more or with a turnover of €2m or more have to have their U-value calculations validated by a notified body.
The BWF has teamed up with a notified body, the British Board of Agrément (BBA), to ensure that all the calculations it supplies can be validated for such SMEs.
Businesses that are too small to make the threshold still have to provide a U-value for building control approval – and the BWF’s basic U-value calculation service is also designed to help them.
BWF technical officer Chris Addison, who runs the BWF’s basic U-value calculation service, said: “Approval of our U-value calculations by the BBA means that joinery firms can be confident that their windows comply with the building regulations, can secure compliance in a cost effective manner and of course can be used for CE marking purposes.”
More information about the service is available on the BWF’s website.
