Product Description

Rigid Polyurethane Foam Board Floor Underfloor Heating Insulation High Compressive for Concrete Slab

Product Description

Rigid Polyurethane Foam Board for floors is a high-compressive PUR and PIR closed-cell insulation panel that supports floor loads while cutting downward heat loss.

Its closed-cell structure gives a thermal conductivity near 0.024 W/(m·K) for PUR (about 0.022 W/(m·K) for PIR), so floors and underfloor heating systems keep heat in the room instead of losing it to the slab below.

A core density of 40–60 kg/m³ and compressive strength of 180 kPa (PUR) to 220 kPa (PIR) or more let the board carry screeds, tiles and normal floor traffic without crushing.

Water absorption at or below 5% (PUR) to 4% (PIR) and low vapour permeability keep the board dry in ground-contact and under-screed assemblies.

The board is light and easy to cut, so it fits quickly between floor joists or under underfloor heating pipes and set-out battens.

Typical applications include ground floors, underfloor heating, basements, mezzanine decks and refurbishment floors where both load and thermal performance matter.

Product Features

High Compressive Strength – 180 kPa (PUR) to 220 kPa (PIR) carries screeds and floor traffic.

Low Thermal Conductivity – 0.022 (PIR) to 0.024 W/(m·K) (PUR) cuts downward heat loss.

Excellent Thermal Insulation – Keeps underfloor heating heat inside the room, not the slab.

Closed-Cell Waterproof – Low water uptake keeps the board dry in ground-contact builds.

PUR / PIR Available – PUR for general floors, PIR for higher load and heat duty.
