The BBA has awarded more than 200 BBA Certificates for PVCu Windows and lists all of the UK's extruders of profiles for these products among its clients. The door market is more fragmented but here again the BBA ticks all the right boxes for approvals. 'We can justifiably claim to be No 1 in approvals in this sector' says Chief Executive Greg Cooper 'and we have made clear our commitment to retain this position by a substantial investment in equipment to test profiles and finished windows and doors to the new European Standards now coming through (EN 12608 for profiles and prEN 14351-1 for window and doorsets)'.

'This is not simply an intention to invest, we have spent the money and now have the equipment in position and ready to go' Included in the array of test equipment is the Atlas Xenon Tester, for accelerated weathering testing - unique to the UK in the field of fenestration - as well as a suite of equipment to test thermal and other properties.

The BBA also expects increased interest in its services related to British Fenestration Ratings Council gradings.

The BBA holds both BFRC gongs - Approved Simulators and Approved Independent Agency - and is the agency of choice for 80% of the window firm ratings currently listed on the BFRC website.
