Product properties
Waterproof
FOAMGLAS® is water- and vapour proof. As an all-glass, 100% closed cell material it retains all the water-resistant properties of glass. Benefit: No moisture absorption, no condensation, no swelling of FOAMGLAS® : prevents corrosion under insulation.
Impervious to water vapour
Each glass cell is hermetically sealed during the manufacturing process ensuring that FOAMGLAS® is totally impervious to water vapour and to all other gases. Benefit: FOAMGLAS® does not require the use of a vapour barrier and the insulated pipe or vessel remains dry to prevent corrosion under insulation. Its thermal insulation value remains constant indefinitely
Non-combustible
FOAMGLAS® made of pure glass, non-combustible and also non-absorbent.
Benefit: Safe storage and a safe installation. As an inorganic material FOAMGLAS® will not burn or support combustion. It ensures fire protection; inflammable liquids and gases cannot pass through FOAMGLAS® (no wicking effect).
Resistant to attack
FOAMGLAS® is inorganic, it will not be damaged by birds or vermin and will not rot in the long term. Benefit: Safe insulation of underground constructions, as FOAMGLAS® provides no food nor nesting source for birds or vermin and does not support the growth of micro-organisms and bacteria.
High compressive strength
FOAMGLAS® gives exceptionally high compressive strength without deformation under permanent load. Benefit: FOAMGLAS® will not compress or settle and provides full support to tank bases and pipe supports, without thermal bridges.
Dimensionally stable
FOAMGLAS® is dimensionally stable, as glass does not shrink or swell. Benefit: No warping or buckling with FOAMGLAS®. It remains stable since it has a similar expansion/contraction coefficient to steel piping and equipment. This gives a minimum of stress to the insulation system, joints and coverings as temperature changes. Preventing excessive expansion/contraction of insulation materials is the best way to ensure that the system remains sealed against moisture.
Acid resistant / chemical resistant
FOAMGLAS® is resistant to organic solvents and nearly all acids, since it is made of pure glass. Benefit: No destruction of the insulation by sour gas or other corrosive media and aggressive plant conditions. The chemical resistance of glass has been universally recognized.
Easily cut to shape
FOAMGLAS® can be easily cut and installed on site or is available prefabricated. Depending on project requirements, FOAMGLAS® can be easily cut on site using a hard-point saw and other simple tools.
