SEALz® Flex Seals are suitable for sealing gaps in elements of construction between fire resisting doors, frames, windows, and adjoining walls or around services where they penetrate fire compartments. The seal produces a voluminous intumescent foam in the event of a fire, sealing the air-gap between the door leaves and frames of a fire resisting doorset.
SEALz® Flex Seals are highly flexible, allowing them to be used for many applications where standard rigid intumescent strips would be impractical.
