About Non Ventilated Sponge Cavity Wall Barrier
The fire proof sponge ensures optimum durability and moisture protection as well as offering continued thermal insulation within the cavity section.The barriers can be fitted horizontally or vertically between brick or block walls, resisting fire and smoke.
It operates as a powerful intumescent seal that in the event of a fire will expand, filling the cavity and stopping the spread of fire and smoke.
Sponge cavity barriers provide their own thermal insulation and also allow for insulation material to be installed above and below the barrier
