Product Description

Fire Retardant B1 Polyurethane Foam Board Vapor Tight Moisture Proof Excellent Thermal Insulation Panel

Product Description

Fire Retardant B1 Polyurethane Foam Board is a rigid PUR insulation panel formulated with flame retardants to meet the B1 difficult-to-ignite classification.

Its oxygen index of 30% or higher makes the foam self-extinguishing, so it stops burning once the flame source is removed and forms a protective char layer.

The panel reaches a thermal conductivity of about 0.024 W/(m·K), combining fire safety with strong thermal performance in a single layer.

A vapor-tight foil facing and a closed-cell core resist moisture movement, keeping the insulation dry and its thermal value stable in humid service.

Typical applications include high-rise exterior walls, public buildings, fire compartment walls, ceilings and any assembly that must meet strict fire-safety rules.

Product Features

Fire Retardant B1 Grade – Oxygen index ≥ 30 makes the foam self-extinguishing and B1 rated.

Vapor-Tight Moisture Proof – Foil facing and closed cells block vapour and keep the core dry.

Excellent Thermal Insulation – About 0.024 W/(m·K) delivers strong energy-saving performance.

Self-Extinguishing Foam – Char layer slows flame spread to improve building safety.

Low Smoke Release – B1 formulation limits smoke emission for safer egress.
