Gypsum Fire Stopping for Walls and Floors (GFS 1000)
Gypsum Fire Stopping for Walls and Floors, GFS 1000, is a single pack factory controlled premix, based on gypsum plaster and vermiculite. GFS 1000 is designed specifically to stop the spread of smoke and fire through openings created in fire rated walls and floors.
Advantages of using GFS 1000
- Easy to install; traditional skills are all that are required on site.
- Seals apertures around penetrating services, irrespective of the degree of complexity within the opening, including: pipe work, cable trays, electrical and fibre optic cables, and ducting.
- Openings to be fire stopped may be of any irregular shape and GFS 1000 easily facilitates localised removal and reinstatement where subsequent additional penetrations are required.
- Suitable for use in return air plenums as, on completion of the fire stop, the surface may be trowelled smooth using conventional plastering techniques.
- Suitable for sealing penetrations through a wide range of structures, such as concrete, brick and block work walls, and concrete floors.
- Affords up to 4 hours fire resistance.
