Product Description

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

Product Description

Fire Retardant B1 Polyurethane Foam Board is a rigid PUR / PIR closed-cell panel formulated to reach a B1 fire rating, for insulation work where low flame spread is important.

The panel uses an oxygen index of 30% or higher so it self-extinguishes once the flame source is removed and forms a protective char layer instead of spreading fire, while a B2 grade remains available where a B1 rating is not required.

Its thermal conductivity of 0.021–0.025 W/(m·K) keeps heat loss low, and the closed-cell structure of 93% (PUR) to 95% (PIR) or more resists moisture so fire and thermal performance stay stable over the service life.

The panel is faced with aluminum foil or glass fleece, which makes it vapor-tight and moisture proof and also gives a clean, flat surface for neat installations.

Volume water absorption stays at or below 5% (PUR) / 4% (PIR) and vapor permeability is about 6.0×10⁻⁹ g/(Pa·m·s) or lower, protecting the core from condensation in humid or ventilated build-ups.

It is not tied to one application and is used wherever a low flame spread rating and thermal insulation are both needed — walls, facades, roofs, ceilings, ducts and general fire-sensitive insulation in buildings and industry.

The panel is installed with continuous sealed joints and a properly detailed vapor barrier, and is kept within its rated service temperature range in normal use.

Product Features

Fire Retardant B1 Grade – Oxygen index ≥ 30% with a self-extinguishing, low-smoke B1 fire rating.

Vapor-Tight Moisture Proof – Aluminum foil facing makes the panel vapor-tight and moisture proof.

Excellent Thermal Insulation – Thermal conductivity 0.021–0.025 W/(m·K) reduces heat loss.

Closed-Cell Waterproof – Closed cells above 93% keep the core dry in humid service.

PUR / PIR Available – B1 grade plus a B2 option cover a range of fire requirements.
