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 closed-cell panel engineered to reach the lowest thermal conductivity in its class, with values down to about 0.021 W/(m·K).

That low conductivity means a thinner panel reaches the same R-value, so more usable space is kept inside walls, roofs, floors and ceilings.

The closed-cell structure of 93% (PUR) to 95% (PIR) or more keeps the core waterproof and dimensionally stable, so the low conductivity is held over the whole service life.

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), covering normal handling and light service loads.

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

It is a general high-efficiency insulation panel and is used wherever heat loss must be minimised — roofs, walls, floors, ceilings, ducts, cold stores, tanks and general envelopes.

For best results the panel is fitted with tightly butted, staggered joints and a continuous vapor barrier, since moisture in the core would raise the conductivity.

Product Features

Low Thermal Conductivity – Thermal conductivity down to about 0.021 W/(m·K), among the lowest available.

Excellent Thermal Insulation – High R-value per thickness keeps more usable space in the build-up.

Closed-Cell Waterproof – Closed cells above 93% keep the core waterproof and stable.

High Compressive Strength – Compressive strength of 180–220 kPa covers normal handling loads.

PUR / PIR Available – PUR and PIR grades cover a wide range of insulation duties.
