What are intumescent batts?
Intumescent batts are specifically designed for sealing around service breaches in walls and floors. Both sides of the intumescent batt are coated with a fire-resistant ablative that will deter flames and smoke in the event of a fire and can do so for up to four hours. When they come into contact with fire or the heat of steel, a chemical reaction will cause the batt to expand and swell, forming a protective layer.
Intumescent batts are extremely lightweight and can be applied to walls, floors, and ceilings as well as flexible walls and concrete floors. These stop a building’s steelwork, pipework, and other structural components from collapsing in the event of a fire.
Fire ratings and compliance
Our intumescent batts meet the requirements of BS476, with the rock mineral wool that makes up a high majority of the slab possessing an extremely high melting point, providing ample and extensive protection against fire.
Benefiting from being odourless, rot-proof, non-hygroscopic, effective against the growth of mould, fungi, and bacteria, as well as not attracting vermin, our batts will comply with all building regulations and comply with fire safety regulations.
An added benefit, we use rock mineral wool in our intumescent batts which can result in lower building insurance premiums compared to plastic foam insulants.
Installation and maintenance
Installation of our slab/batts is simple. Cut the slab/batt to fit the opening of the wall adhering with the adhesive supplied, and fit the batts around any PVC, copper or steel pipes. Holes for pipes should be cut to allow them to fit through, with our approved sealant applied around the external edges, guaranteeing a tight seal.
