This product is a non-toxic, non-irritant, flexible water based sealant to ensure a fire resistant seal on gaps around any wall boxes, cables, conduit, busways and ducts which penetrate walls, floors and ceilings. It can also be used to replace any intumescent material inadvertently removed during wall box installation.

Supplied in 300ml cartridges, The Voltex AG Fire Rated Intumescent Sealant expands when heat is applied, filling the penetration.
