Product Description

Low Thermal Conductivity Polyurethane Foam Insulation Board Closed Cell Waterproof Panel

Product Description

Low Thermal Conductivity Polyurethane Foam Insulation Board is a rigid PUR / PIR panel built to squeeze the most thermal resistance out of every millimetre, with thermal conductivity as low as 0.021–0.025 W/(m·K).

Few common insulation materials insulate as well per unit thickness as rigid polyurethane foam, and for the PIR grade the value can fall to about 0.022 W/(m·K) at 25 °C, so a thinner board achieves the same R-value as a much thicker alternative.

That efficiency directly saves space: roofs, walls, floors and cold rooms can be insulated to target without sacrificing internal headroom or usable floor area.

The low lambda is backed by a closed-cell structure above 93% (PUR) / 95% (PIR), which is what keeps the value stable over time — open-cell or moisture-logged insulation loses its performance, while a dry closed-cell core holds its rating.

A core density of 40–60 kg/m³ gives a compressive strength at 10% deformation of at least 180 kPa (PUR) or 220 kPa (PIR), and water absorption stays at or below 5% (PUR) / 4% (PIR).

Water vapour permeability of about 6.0 × 10⁻⁹ g/(Pa·m·s) or lower keeps the core dry, so the low conductivity is preserved in humid conditions rather than degrading.

Typical uses include energy-efficient roofs, walls and floors, cold store and freezer panels, HVAC equipment, tanks and vessels, and any project with a tight energy target.

The board is faced with aluminum foil or glass fleece and cut to size on site; the vapour barrier should be continuous and the joints staggered to protect the low lambda value.

PUR serves general duty from –50 °C to +100 °C, while PIR extends the range to deep cold and adds a higher B1 fire rating with low smoke.

Product Features

Low Thermal Conductivity – As low as 0.021–0.025 W/(m·K) for maximum R-value per mm.

Closed-Cell Waterproof – Closed cells above 93% keep the low lambda stable over time.

Excellent Thermal Insulation – Thinner boards reach the same R-value as bulkier materials.

High Compressive Strength – 180–220 kPa at 10% deformation.

PUR / PIR Available – PUR for general duty, PIR for cold and fire duty.
