Glass Wool Insulation
Glasswool is the most common type of insulation used in residential homes and commercial buildings across the world. It is a type of insulation that is made of glass fibres and is also referred to as fiberglass insulation or earthwool insulation. The glass fibres in glasswool insulation create millions of tiny air-pockets inside the insulation which traps air between the fine fibers and prevents heat from passing through it. In addition, glasswool insulation is not a great conductor of heat preventing heat from transferring through the material. This gives glasswool its insulating properties and allows it to maintain stable temperatures within your home, keeping your home warm in winter and cool in summer.
How Is Glasswool Insulation Made?
Glasswool is made from up to 80% recycled glass material as well as sand, soda ash, borax, and dolomite. There are two types of recycled glass material used; plate glass (which comes from windows and car windscreens) and container glass (which comes from bottles and jars). These ingredients are mixed together and sent to a furnace tank which is gas oxygen fired with an electric boost (environmentally friendly process) and set at a temperature of around 1400oC. A binder is then added which acts as a glue so that it can be formed into rolls or slabs of insulation. The binder used in Knauf Earthwool is an innovative ECOSE ® Technology binder which is a bio-based organic formula that has no formaldehyde, colours or dyes added to the process.
