Product Description

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


 

Product Description

 

Fire Retardant B1 Polyurethane Foam Board is a rigid PIR panel formulated to meet a B1 fire rating, so it self-extinguishes, produces low smoke and keeps the closed-cell insulation performance that polyurethane foam is known for.
 
The core reaches an oxygen index of 30% or more, which is what allows the board to pass a B1 classification and stay self-extinguishing away from a flame source — a key requirement in public buildings, transport and industrial plants.
 
Alongside the fire performance, thermal conductivity stays as low as 0.022 W/(m·K), so the board insulates as effectively as a standard rigid PU panel while offering a better reaction to fire.
 
The closed-cell content above 95% makes the PIR core vapour tight and waterproof, so it resists moisture ingress and keeps its insulation value and fire performance over the service life.
 
A core density of 48–60 kg/m³ gives a compressive strength at 10% deformation of at least 220 kPa, and the board holds its dimensions from –50 °C to +120 °C with short excursions to +150 °C.
 
Where a project must also control moisture, the vapour-tight face and low water absorption (≤ 4.0% by volume) work together with a continuous vapour barrier to keep the core dry.
 
Typical uses include fire-sensitive wall and roof linings, duct insulation, modular buildings, transport interiors, cold rooms and industrial enclosures where a B1 rating is specified.
 
The board is cut to size on site and fitted with tightly butted, staggered joints; cut edges are sealed and the aluminium foil facing is kept intact so the fire and vapour performance is not interrupted.
 
For higher-risk areas the PIR grade should be selected over standard PUR so the B1 rating and low smoke behaviour are maintained throughout the build-up.
