BBA Agrément Certificate
Certificate type
A flexible cement/ calcium building board, for applications that require a slightly lighter board with improved fire properties.
Flexible cement/ calcium building board, for applications that require a slightly lighter board with improved fire properties. Product offers very similar properties to cement particle board, however due to the calcium additives it offers a greater fire resistance. Fully tested to achieve a one hour through wall solution with external sheathing board properties.
As a sheathing board, it can be used behind rain screen cladding, insulated facades and cedar cladding (in this application, the use of a water resistant/ breathable membrane such as Tyvek, on to the face of the board, is recommended in line with good building practises for external cladding). CE marked and conforms to BS EN 12467.
Key applications:
- Sheathing board on metal and timber frame.
- OEM Application where improved strengths and density are required.
- Fire rated flooring and roofing.
- Fire rated walling.
