Product Description

Cellular Glass Insulation Board Green Roof Drainage Closed Cell Waterproof Foam Glass

Product Description

Made from recycled glass fired with a foaming agent, Cellular Glass Insulation (Foam Glass) is a rigid, non-combustible insulation whose 100% closed-cell body is waterproof, vapor-tight and load-bearing, keeping its thermal value for the life of the structure.

On green roofs, foam glass insulation board sits beneath the growing medium, where it drains freely, resists root and water pressure, and holds its thermal value in permanently damp conditions.

Its closed-cell, waterproof structure means the board never absorbs irrigation or storm water, so it keeps insulating even after years of saturation, unlike open-cell or fibrous insulation.

Lightweight yet load-bearing and non-combustible, the board supports the roof build-up and adds a Class A1 fire barrier beneath the planting layer.

Product Features

Closed Cell Waterproof – Never absorbs irrigation or storm water, so it keeps insulating when permanently damp.

Green Roof Drainage Board – Drains freely beneath the growing medium and resists root and water pressure.

Lightweight – Low density reduces structural load on green roof build-ups.

Class A1 Non-Combustible – Inorganic glass body adds a fire barrier beneath the planting layer.

Permanent Dimensional Stability – Holds shape and thermal value through wet-dry and freeze-thaw cycles.
