Doors and Windows

BBA Test Services has tested doors, windows and rooflights for many years in support of BBA Certification and now offer this service directly to manufacturers as a precursor to application for a Certificate, or as part of their own research and development programmes.

We are experienced in performing a wide range of tests on windows, doors, rooflights, profiles and hardware.

Our tests ensure that products are thermally efficient, secure, weathertight and durable.
