Foamglas (Cellular Glass)
−200°C to 430°C
Main applications
- completely non-combustible
- zero water absorption
- vapour tight
- covering −260°C to +430°C
- ideal for LNG tanks
- cryogenic piping and cold stores
Key Features
Completely non-combustible foam insulation
Cellular glass — unlike organic foam insulation it does not burn at all
Fully waterproof and vapour tight
A closed-cell glass structure absorbs no water or water vapour — fully waterproof insulation from cryogenic to hot service
An extraordinary range: −200°C to 430°C
From cryogenic (LNG, liquid nitrogen) to 430°C — one material covering the entire range
High compressive strength for loaded service
The compressive strength characteristic of cellular glass allows safe use in loaded floor and basement insulation
Chemical and corrosion resistance
As a glass material it resists strong acids, alkalis and organic solvents — ideal for chemical plant and corrosive environments
