Product Description

Rigid Polyurethane Foam Board PUR PIR Excellent Thermal Insulation Closed Cell Panel

Product Description

Rigid Polyurethane Foam Board is a high-performance thermal insulation panel produced from rigid polyurethane foam in both PUR and PIR (polyisocyanurate) closed-cell grades, and it delivers one of the lowest thermal conductivity values among common insulation materials, typically 0.021–0.025 W/(m·K).

Because the rigid closed-cell core insulates so well per millimetre, a thin panel still reaches a high R-value and leaves more usable space inside any build-up — a real advantage where wall, roof or floor thickness is limited.

Each board is made on a continuous foaming line that bonds the rigid foam core to a facing such as aluminum foil or glass fleece, giving consistent thickness, a flat surface and long-term dimensional stability over the service life.

A core density of 40–48 kg/m³ (PUR) to 48–60 kg/m³ (PIR) gives a compressive strength at 10% deformation of at least 180 kPa (PUR) or 220 kPa (PIR), so panels resist normal handling, foot traffic loads and service pressure.

Volume water absorption stays at or below 5% (PUR) / 4% (PIR) and water vapour permeability is about 6.0 × 10⁻⁹ g/(Pa·m·s) or lower, keeping the foam dry and thermally stable even in humid or condensing conditions.

The closed-cell content above 93% (PUR) / 95% (PIR) is what locks out water vapour; once moisture enters the foam the thermal performance falls sharply, so a continuous, sealed build-up is essential on site.

Rather than being tied to one duty, the board suits a broad range of insulation work — roofs, walls, floors, ceilings, cold rooms, ducts, tanks, pipework and general building or industrial envelopes — so the same panel can be specified across a whole project.

PUR covers general building and HVAC duty from –50 °C to +100 °C, while PIR extends service down to –196 °C and up to +120 °C with a higher B1 fire rating, so a single board family fits both warm and cold applications.

On site the vapour barrier should be kept continuous and the panel joints staggered so water vapour cannot bypass the insulation; cut edges should be sealed and the facing protected so the core stays vapour tight.

Product Features

Excellent Thermal Insulation – Thermal conductivity 0.021–0.025 W/(m·K) cuts heat loss across many build-ups.

Closed-Cell Waterproof – Closed cells above 93% block water uptake and keep performance stable.

Lightweight Space-Saving – High R-value per thickness saves space in wall, roof and floor assemblies.

High Compressive Strength – 180–220 kPa at 10% deformation suits normal handling and service loads.

PUR / PIR Available – PUR for general duty, PIR for cold insulation and a higher fire rating.
