Fireshield is a vapour permeable walling underlay with an intumescent coated surface. Fireshield is suitable for all walling applications including those in multiple storey buildings. The intumescent coating helps protect the substrate by reducing the risk of fire taking hold and significantly reduces the formation of droplets and smoke. It is installed and fixed to the substrate in the same manner as standard breather membranes using mechanical fixings.
Key points :
The unique intumescent coating helps protect the substrate
Vapour permeable walling underlay for use either directly onto sheathing or insulation
Class B, s1-d0 but performs differently to other similar class products
Complies with BS5250, BS4016 & NHBC requirements for vapour permeable walling underlays
Ideal for use in rainscreen / façade construction
Robust & durable
Suitable for applications over 18m high (11m in Scotland)
