The (BBA) is the UK’s major authority offering approval and certification services to manufacturers and installers alike. They make sure we do as we claim, so you can rest assured knowing the windows have come through the most rigorous testing and that someone else is looking out for your interests, making sure we make quality sash windows.The BBA was set up on behalf of the Department for Communities and Local Government to provide independent testing. This validates claims made by manufacturers that their products conform to regulations and perform as expected. NHBC generally requires BBA certification for new buildings. BBA Certificates have been providing authoritative and independent information on the performance of building products for over 35 years. Every Agrément Certificate contains important data on durability, installation and compliance with Building Regulations.BBA Approval is recognised by building control, government departments, architects, local authorities, specifiers and industry insurers like the NHBC. Because our manufacturing facility is BBA certified, you can be confident that every window we make, meets the highest standard.
Our product range is fully BBA approved. That means we’ve asked that every component is tested, including the balances, even the unique hardware; additionally, and unlike any other company, our method of plant on Georgian bars also gets their approval for the next ten years.20,000-cycle endurance testing is to simulate a “whole of life” test, it is an onerous test designed to recreate a 20-year lifetime of a product.
