HiBAR Spray-Applied Fire-Resistive
Material (SFRM)
HiBARTM is a ULC listed,
spray applied semi cementitious mineral fibre insulation, for fire
rating structural steel. HiBARTM also has thermal and
acoustical properties. It can be spray applied over rigid
structural substrates and exterior or partition walls. It provides
acoustical treatment for ceilings and walls in noisy production
areas or large rooms such as gymnasiums or swimming pools where
both sound absorption and aesthetic enhancement is desired.
Condensation control is also provided on exposed structural
components that are in contact with cold exterior surfaces.

Basic Uses
Spray-applied fireproofing for use over
rigid structural substrates such as
open web steel joists, beams, columns,
floor/ceiling assemblies and exterior or
partition wall units.
Thermal insulation for prefabricated
metal buildings, corrugated metal
roof assemblies, underside of
concrete slabs and masonry or
metal wall assemblies.
Spray-applied acoustical treatment
for ceilings and upper walls in noisy
production areas or in large rooms
such as gymnasiums or swimming
pools where both sound absorption
and aesthetic enhancement is desired.
Spray-applied treatment to provide
condensation control on exposed
structural components that are in
contact with cold exterior surfaces.

Limitations
- HiBARTM is not suitable for exterior surfaces that might be exposed to moisture infiltration or to interior areas subjected to high humidity unless adequate ventilation is provided.
- Maximum thickness on rigid overhead areas without mechanical support is 75 mm. Thickness of over 38 mm generally require treatment with primary adhesive.
- Wood surfaces or substrates covered with high-gloss or water emulsion paints may require treatment with primary adhesive.
- Substrates covered with dirt, loose scale, oil, peeling paint or other substances that would impair bonding must be cleaned or sand blasted, and checked for acceptable bonding properties before application of HiBAR. Consult with a HiBAR representative.

Composition
HiBARTM is a blend of
specially manufactured inorganic mineral fibres and proprietary
binders. The composite contains no asbestos or free crystalline
silica.
