Overview
FOAMGLAS® is classified as a non-combustible material (ISO 1182 and other tests) which is a highly competitive advantage in all fire risk applications. The main criteria for fire safety are: the non-combustibility and the non-absorptivity of a material. Cellular glass is non combustible and non absorbent and will offer the best fire protection to the insulated structure. Insulants that are non-combustible but absorb combustible liquids or combustible gases will increase the combustibility of the system. FOAMGLAS® neither absorbs oils, other fluids or highly flammable hydrocarbons, unlike other insulants made of mineral fibres or plastic foams. Cellular glass can be used in the temperature range -260°C to + 430°C. The closed cell structure of FOAMGLAS® guarantees that no wick effect will lead to spontaneous ignition. No smoke or toxic gases can develop from FOAMGLAS® due to its chemical composition made from pure glass.
FOAMGLAS®, being chemically resistant and free from corrosive agents, helps protect pipes and equipment for their life-time. FOAMGLAS® is resistant to salt water, acids, petrol and organic solvents.
Impervious to water and water vapour, FOAMGLAS® protects totally against corrosion, avoids ice formation and offers excellent thermal control in the long term. No vapour-barrier or gas-impermeable membrane is needed.
The laboratory controlled high compressive strength of FOAMGLAS®, ranging from 0.5 to 1.7 N/mm², can support permanent loads from tank bottoms etc., without cracking. Mechanical fixings using stainless steel straps do not compress this rigid insulation material to which metal cladding or jacketing can be easily fitted. Personnel walking on insulated pipework will not cause any damage to the insulation.
The perfect dimensional stability of cellular glass has proved to be advantageous under exposure to major temperature and/or moisture variations.
When pipes or reservoirs are installed under ground or at ground level, it is most important that the installation is both vermin and rotproof.
