A. Proctor Group is introducing a fibre cement sheathing board to its range of facade solutions. Used in conjunction with the highly regarded and well-established Wraptite® external air barrier, the A1 Cement 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 A1 Cement Board means it can be used with Wraptite® to support compliance with fire safety requirements for relevant buildings.
“As a cementitious product, A1 Cement Board is automatically classified as non-combustible,” said Will Jones, Head of Business Development at the A. Proctor Group. “The fire performance data we have gathered from through-wall testing ensures compatibility of the sheathing board and our Wraptite® membrane. Customers can therefore feel assured when choosing a fully-adhered external air barrier and vapour permeable membrane.”
Key to the development of 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). “A1 Cement Board is a lightweight board for easier handling, and it is score and snap to make cutting and installation easier.”
As a cementitious board, cladding rails and brackets can be fixed directly to A1 Cement Board. Specialised fasteners designed for fixing through to the frame behind are therefore unnecessary. And thanks to the compatibility with Wraptite®, which offers a W1 classification for water hold out, there is no need to use tapes and sealants on the sheathing board to provide airtightness and temporary weather protection.
As with all products offered by the A. Proctor Group, 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 www.proctorgroup.com
