A. Proctor Group launches A1-rated, Wraptite® -compatible sheathing board

The A. Proctor Group is introducing a score and snap sheathing board to its range of facade solutions.

Used in conjunction with the highly regarded and well established Wraptite® external air barrier, the Proctor A1Cement Board can help specifiers and contractors move more towards a system solution.

While suitable for all buildings, the through-wall fire testing carried out featuring Proctor A1 Cement Board means it can be used with Wraptite to support compliance with fire safety requirements for relevant buildings.

“As a cementitious product, Proctor A1 Cement Board is automatically classified as non-combustible,” said Will Jones, Head of Business Development at the A. Proctor Group. “Through-wall testing has confirmed the sheathing board’s compatibility with our Wraptite membrane, delivering a result of 120 minutes without integrity failure. Customers can therefore feel assured when choosing a fully-adhered external air barrier and vapour permeable membrane.”

There are further benefits from the compatibility with Wraptite. As the membrane offers a W1 classification for water hold out, there is no need to use tapes and sealants on the Proctor A1 Cement Board to provide airtightness and temporary weather protection.

Key to the development of Proctor A1 Cement Board was the desire to offer the best possible all-round solution. As a result, it combines the benefits of traditional fibre cement boards with desirable qualities of newer gypsum sheathing boards that have gained acceptance in the marketplace.

“Fibre cement boards tend to be heavy and difficult to cut on site,” explained Lewis Stanley, Business Development Manager (High Rise & Facades). “Proctor A1 Cement Board is a lightweight board for easier handling, and it is score and snap to make cutting and installation easier.”

As with all products offered by the A. Proctor Group, Proctor A1 Cement Board is backed up by comprehensive technical support, plus on-site support including all complementary fixings and accessories. To find out more visit
