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.

Intertek Testing Services NA Ltd. (Intertek) has conducted testing for Can-Cell Industries, Inc., on a sample of HIBAR spray-applied fire-resistive barrier, to evaluate the thermal protection properties. Testing was conducted in accordance with CAN/ULC S124-06, Standard Method of Test for the Evaluation of Protective Coverings for Foamed Plastic.




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 HiBARTM.


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