untitledSheerframe, part of the Litchfield Group, has just announced that its cavity closer profile has received BBA accreditation. Gary Doxey, Marketing Manager, said, “The cavity closer profile is an innovative, high quality solution, so we are delighted that it has received the stamp of approval from the British Board of Agrément.”

The cavity closer profile was launched last year and is the perfect example of Sheerframe’s sustainable ethos in action. It’s an innovative, insulation-free profile that is made out of recycled PVC-U. It uses a unique, high performance multi-chambered air pocket solution that means it can meet the Accredited Construction Detail (ACD) minimum thermal resistance path of 0.45m2K/W without the need for additional insulation or polystyrene inserts. The solution ensures optimal thermal performance between the window and the PVC-U closer, preventing cold bridging and condensation issues. The closer acts as a template for the bricklayer and a simple fixing solution for Sheerframe glazed windows, as well as sealing and insulating the cavity opening, providing a damp proof course around the window reveal.

BBA Approval is recognised by building control, government departments, architects, local authorities, specifiers and industry insurers like the NHBC, providing a valuable seal of approval for everyone from specifier to end user, so Gary is right to be proud of the accreditation.

Sheerframe’s products are suitable for every application including trade, retail, social housing, private housebuilding, commercial buildings, schools and hospitals. The company has been renowned for its innovative approach to product design ever since it became the first UK company to extrude PVC-U windows back in the 1980s. Today, as the cavity closer profile demonstrates, it’s blazing a trail for the vital part that PVC-U can play in sustainable building practices.
