What fire rating does Evostik Fire Retardant Foam achieve?

This foam achieves a 4-hour fire rating when tested to BS476 Part 20. It forms an airtight seal that prevents the transmission of smoke through joints and penetrations, making it suitable for fire-rated wall and floor assemblies.

Where do you use fire retardant expanding foam?

Fire retardant foam is used for filling and sealing joints, gaps and penetrations that require fire resistant properties. Common applications include pipe and cable penetrations through fire walls, service risers, gaps around fire doors and anywhere building regulations require fire-rated sealing.

How does fire retardant foam differ from standard expanding foam?

Standard expanding foam has no fire resistance rating and will burn. Fire retardant foam is a modified polyurethane formulation that resists fire and prevents smoke transmission for the rated period. It still expands and insulates like standard foam but meets BS476 Part 20 requirements.

What size is the Evostik Fire Retardant Foam canister?

The canister is 700ml, which is the standard pressurised aerosol size compatible with most foam gun applicators. It uses atmospheric moisture to cure, expanding rapidly after dispensing into a fine honeycomb structure with excellent thermal and acoustic insulation properties.

Is fire retardant foam suitable for exterior use?

The foam is primarily designed for interior fire-rated applications. While the cured foam bonds to most construction materials and has good moisture resistance, its primary purpose is fire compartmentation. For exterior weatherproofing without fire requirements, standard or gun-grade PU foam may be more cost effective.
