PROMASEAL® FyreStrip

PROMASEAL® FyreStripis 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).

PROMASEAL® FyreStripis ideal for sealing high movement joints at junctions between compartment walls and floors. Its flexibility makes them suitable for use in a variety of configurations. The fire performance of PROMASEAL® FyreStripwill vary according to the particular application. The width of the gap into which the strip will be inserted as well as the orientation of the strip affect the level of fire resistance provided.

The thickness of PROMASEAL® FyreStripis determined by the minimum and maximum width of the gap expected during the lifetime of the building. For 240 minute fire resistance, insulation and integrity performance, PROMASEAL® FyreStripis supplied in the following dimensions:

  1. 1000mm (L) x 28mm (W) x 90mm (D), FS20
