Product Description

Fire Retardant B1 Polyurethane Foam Board High Temperature Resistant Vapor Tight Insulation Panel

Product Description

Fire Retardant B1 Polyurethane Foam Board is a rigid PIR (polyisocyanurate) panel formulated to meet a B1 fire rating, so it self-extinguishes, produces low smoke and still 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 for public buildings, transport and industrial plants.

PIR is more heat stable than standard PUR, so the board holds a long term service temperature up to +120 °C with short excursions to +150 °C, and resists thermal ageing, shrinkage and powdering far better in hot pipelines and equipment insulation.

Thermal conductivity stays low at about 0.022 W/(m·K), so the board insulates as effectively as a standard rigid PU panel while offering a better reaction to fire and a higher service temperature.

Closed-cell content above 95% makes the PIR core vapor tight and waterproof, and volume water absorption stays at ≤ 4.0%, so the board resists moisture and keeps both its insulation value and its 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 dimensional stability at –50 °C for 48 h stays within 1.0%, so the panel holds its shape through thermal cycling.

Where a project must also control moisture, the vapor-tight face and low water absorption work together with a continuous vapor barrier; cold insulation must always sit behind a membrane such as mastic or an aluminum foil composite film.

The board is cut to size on site and fitted with tightly butted, staggered joints; cut edges are sealed, the aluminum foil facing is kept intact, and the panel must not run above +120 °C for long periods or the foam can age and powder.

Typical uses include fire-sensitive wall and roof linings, duct insulation, hot water and steam-adjacent pipework, heat exchangers, ovens, drying equipment and industrial enclosures where both a B1 rating and high temperature resistance are specified.
