Heard Group Expansion Joint Fire Seal

PROMASEAL® FyreStrip is a highly compressible, flexible, fire resistant expansion strip seal which is used where movement joints are formed in the structure of a building.

It consists of layers of PROMASEAL® Grafitex intumescent material bonded to a special foam and it has been successfully tested for up to 240 minute fire resistance for movement joint seals within concrete/masonry compartment floors and walls (with an equal or greater fire resistance level).

The flexibility of PROMASEAL® FyreStrip is suitable for use in a variety of configurations. The fire resistance performance of PROMASEAL® FyreStrip will vary depending on applications and types of the penetrating elements. The gap width for which the FyreStrip will be inserted and the orientation of the insertion will affect the level of its fire resistance performance.
