Glass wool is an inorganic insulating material made of artificial mineral fibres (mineral wool) and is made from the fibres of molten glass, which are bonded with synthetic resin and to which small amounts of mineral oil are added. The insulating effect is created by the air pockets between the fibres. Glass wool is resistant to rotting, vermin and fungal infestation, is open to diffusion and easy to process. It loses its good insulating effect when it is soaked through. The production of glass wool is very energy-intensive. Due to organic additives, it is only recyclable to a limited extent. Glass wool is available in the form of dimensionally stable, elastic insulation boards or roll goods in thicknesses of 100 - 260 mm.
