SFRM (Sprayed Fire-Resistant Material)

Sprayed Fire-Resistive Material (SFRM) is the technical term used for Spray Applied Fireproofing. It is a type of passive fireproofing used in buildings to delay or prevent steel and concrete structures from failing due to exposure to high temperatures during a fire. The primary function of SFRM is to insulate steel and metal decking from the high temperatures generated during a fire, but it also has thermal and acoustical properties and controls condensation.

SFRM is composed of cement or gypsum and may contain other materials such as mineral wool, quartz, perlite, or vermiculite to help lighten the solution or to add air as an insulator. Chemical hardeners may be used to speed up hardening or make the final fireproofing harder than normal. It is available as a wet or dry spray formula and can be troweled on. Modern formulas are asbestos-free and do not contain free crystalline silica.

Key attributes

• Meet the requirements of various building codes and standards, including BS 476, AS 1530.4, ASTM E119, and UL 263.
• Provide up to 240mins FRR Fire Protection on a range of substrates.
• Isolatek Type 400 and MII are highly durable and can withstand exposure to the elements, making it a long-lasting fire protection solution for buildings.
• Can be easily sprayed onto building components, making it a convenient and efficient fire protection solution.
