Product Description

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

Product Description

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

Because a thin board reaches the same R-value as a thicker conventional insulation, designers can keep walls, roofs and floors slim while maximizing the usable space inside a building.

The 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, flatness and long-term dimensional stability.

PUR rigid foam for heating and HVAC service uses a core density of 40–48 kg/m³ (commonly 45) and a thermal conductivity at 23 °C of ≤ 0.024 W/(m·K), with a compressive strength at 10% deformation of at least 180 kPa.

PIR rigid foam for industrial cold insulation uses a core density of 48–60 kg/m³ (commonly 50 ± 5) and a thermal conductivity at 25 °C of ≤ 0.022 W/(m·K), reaching about 0.017–0.019 W/(m·K) at –100 °C, with a compressive strength of at least 220 kPa.

Closed-cell content is 93% or more for PUR and 95% or more for PIR, and volume water absorption stays at ≤ 5% (PUR) / ≤ 4% (PIR), so the foam resists moisture and keeps its insulation value in service.

Water vapor permeability is ≤ 6.0 × 10⁻⁹ g/(Pa·m·s) for PUR and ≤ 5.8 × 10⁻⁹ g/(Pa·m·s) for PIR; cold insulation must always sit behind a continuous vapor barrier such as mastic or an aluminum foil composite membrane.

Rated service spans –50 °C to +100 °C for PUR (short time +120 °C) and –196 °C to +120 °C for PIR (short time +150 °C), and the foam must not run above +120 °C for long periods or it can age, shrink and powder.

Typical applications include walls, roofs, floors, ceilings, cold rooms, ducts, tanks and pipework; panels are cut to size on site with staggered joints and a continuous vapor barrier so the closed-cell core stays dry.

Product Features

Excellent Thermal Insulation – 0.021–0.025 W/(m·K) keeps heat loss low in slim build-ups.

Closed-Cell Waterproof – Closed cells ≥ 93% (PUR) / ≥ 95% (PIR) block water uptake.

Lightweight Space-Saving – High R-value per thickness saves space in walls and roofs.

PUR / PIR Available – PUR for heating and HVAC, PIR for industrial cold insulation.

Easy Installation – Light panels cut and fit quickly with staggered, sealed joints.
