Product Description

Cellular Glass Insulation Board Flat Roof High Compressive Strength Closed Cell Foam Glass

Product Description

Cellular Glass Insulation, also known as Foam Glass, is a rigid, non-combustible thermal insulation made of millions of sealed glass cells. Its 100% closed-cell structure makes it waterproof, vapor-tight and highly compressive, ensuring permanent thermal performance without moisture absorption.

In flat roof systems, the closed-cell foam glass board is laid directly beneath the waterproof membrane as a load-bearing thermal layer. Its high compressive strength carries rooftop equipment, foot traffic and wind uplift without crushing or settling.

Because the board is 100% closed-cell and vapor-tight, it does not absorb water or lose thermal value after leaks or ponding. Unlike fibrous insulation it can be dried and reinstalled instead of being torn out and replaced.

Non-combustible to Class A1 and dimensionally stable, the board adds fire protection and a flat, dependable substrate for the whole roof build-up.

Product Features

High Compressive Strength – Carries rooftop equipment, foot traffic and wind uplift without crushing or settling.

Closed Cell Waterproof – Sealed glass cells resist water uptake, so thermal value stays stable after leaks or ponding.

Flat Roof Insulation – Laid beneath the waterproof membrane as a load-bearing thermal layer.

Class A1 Non-Combustible – Inorganic glass body will not burn or smoke, adding fire protection to the roof.

Permanent Dimensional Stability – No aging, shrinking or warping, keeping the roof build-up flat and dependable.
