Glass wool is made from silica sand, an inorganic raw material. It is produced through heating silica sand at 1200˚C – 1250˚C and transforming it into fibres. It can be manufactured in the forms of blanket, board, pipe or loose in different size and with different technical properties, with different facing materials according to the intended use and the place of use. It is used for thermal insulation, sound insulation, acoustic comfort as well as fire safety.

Depending on the product type, the temperature of use is between -50/+250°C. This temperature reach 500°C for loose glass wool products. It is lightweight and commonly rot proof, resistant to aging and does not corrode, decompose or allow mold formation. They are typically resistant against insects and microorganisms
