Product Description

Waterproof Polyurethane Foam Board Closed Cell Vapor Tight High Compressive Strength for Roof Foundation

Product Description

Waterproof Polyurethane Foam Board is a rigid PUR insulation panel built for damp, wet and ground-contact applications where moisture resistance is critical.

With a closed-cell content above 94% and water absorption below 2%, the board resists liquid water and vapour, protecting both the insulation and the structure.

A compressive strength of 220 kPa or more lets the board carry overburden and roof traffic without crushing, so it suits inverted roofs and foundation walls.

Its low thermal conductivity of about 0.024 W/(m·K) keeps heat loss low even after long exposure to moisture, maintaining stable performance over time.

Typical applications include inverted roofs, foundation and basement walls, below-grade retaining walls, plaza decks and wet industrial areas.

Product Features

Closed-Cell Waterproof – Above 94% closed cells give water absorption below 2% by volume.

Vapor-Tight Moisture Proof – Low vapour permeability keeps the board dry in ground contact.

High Compressive Strength – Above 220 kPa carries overburden and roof traffic without crushing.

Stable Wet Performance – Low conductivity near 0.024 W/(m·K) holds up under moisture.

Long Service Life – Resists rot and biological attack for durable below-grade use.
