Product Description

Self Extinguishing Polyurethane Foam Board B1 Fire Retardant Vapor Tight Insulation Panel

Product Description

Self Extinguishing Polyurethane Foam Board is a rigid PUR / PIR closed-cell panel formulated to reach a B1 fire rating, so it stops burning once the flame source is removed.

The panel uses an oxygen index of 30% or higher and forms a protective char layer instead of spreading flame, giving self-extinguishing, low-smoke behaviour, while a B2 grade remains available where B1 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.

A core density of 40–60 kg/m³ gives compressive strength at 10% deformation of at least 180 kPa (PUR) or 220 kPa (PIR), covering normal handling and service loads.

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

It is a general fire-rated panel rather than one fixed duty and is used wherever low flame spread and thermal insulation are needed together — walls, facades, roofs, ceilings, ducts and general fire-sensitive insulation.

Panels are installed with continuous sealed joints and a properly detailed vapor barrier, and are kept within the rated service temperature range in normal use.

Product Features

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

Vapor-Tight Moisture Proof – Foil or fleece facing makes the panel vapor-tight and moisture proof.

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

Char-Forming – Forms a protective char layer to slow fire spread.

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