Y-wall is a flexible cement/calcium building board, for applications that require a slightly lighter board with improved fire properties.
As a sheathing board, it can be used behind rain screen cladding, insulated facades, cedar cladding to name but a few applications. In this application, we would recommend the use of a water resistant/ breathable membrane such as Tyvek, on to the face of the board, in line with good building practises for external cladding.
The product offers very similar properties to that of cement particle board, but due to the calcium additives, it has much greater fire resistance properties. This is to meet the ever more stringent demand from specifiers, clients and insurers in the market place.
