Gaps of every type within the building envelope require a fire stopping solution. For all linear movement and building gap seals, Nullifire include a range of fire-rated foams, compressible fibre strips as well as acrylic and silicone sealants.

Nullifire FF197 Gun Grade Fire Rated PU Foam

Nullifire FF197 is an exceptional FR rated Foam with unique technology and is used to seal door frames, window frames and linear gaps throughout the fire rated areas of a building.

Nullifire FJ200 Flexible Intumescent Gap Seal

Nullifire FJ200 is elastomeric foam laminated with a graphite based intumescent compound on both sides. It is designed to perform as a 2 hour barrier in construction movement joints, when tested to EN 1366-4 and BS476. Designed for long linear installations in horizontal and vertical applications which when exposed to fire expands protecting penetrations including cables, cable bunches, cable trays, plastic and metallic pipes. FJ200 maintains the integrity and insulation performance of the seal through masonry/blockwork walls.

Nullifire 703 Neutral Cure Fire Rated Silicone

Nullifire FS703 Silicone Sealant is a single-part alkoxy-based fire resistant, elastomeric, neutral cure silicone sealant. Provides up to 4 hours fire protection at internal and external building gaps and movement joints.

Nullifire FS700 Dynamic Acrylic Sealer

Nullifire FS700 is a waterborne, single pack acrylic based sealer used to form linear gap seals where gaps are present in floor and wall constructions.  The product is designed to be used in conjunction with a light-weight mineral fibre material to form a fire seal at the junction between floor slab and head of wall. The intended use of system FS700 is to reinstate the fire resistance performance of gaps in and joints between joints in rigid floor and wall constructions.
