BBA Agrément Certificate
Certificate type
A vapour permeable walling underlay.
Application
Suitable for use in rainscreen / facade construction. Fireshield is suitable for all walling applications including those in multiple storey buildings.
Description
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.
Features and benefits:
- 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 BS 5250, BS 4016 and NHBC requirements for vapour permeable walling underlays.
- Suitable for use in rainscreen / façade construction.
- Robust and durable.
- Suitable for applications over 18 m high (11 m in Scotland).
- BBA certified.
