Knauff Earthwool Glass Mineral Wool Insulation

Glass mineral wool is, quite simply, the most efficient, flexible, economical and environmentally friendly insulation product you can choose.

Thermal performance
Heating costs in a building insulated throughout with glass mineral wool can be reduced by up to 60%.

Acoustic performance
Noise and noise pollution are areas in which regulations are becoming increasingly strict, with demand for improved levels of acoustic insulation for floors and party walls to increase comfort and quality of life for occupants.

Environmental performance

Glass mineral wool is one of the most environmentally friendly, stable and sustainable insulants available. 

Knauff and the environment.
The Glass Mineral Wool is available in the form of rolls. The density for glass mineral wool ranges from 10 to 85 kg/m³. In general, glass mineral wool consists of at least 92.5% inert material. The inert part is made of recycled glass (external cullet, up to 80% of the composition) and mainly sand and dolomite. The remaining fraction (less than or equal to 7.5%) is made of bio-based binder components. At Knauf Insulation, the binder used for the GMW products is the ECOSE binder whose origin is plant starch.

Infinitely recyclable

After a long, long useful life, Knauff insulation creates no handling or containment problems for contractors when it comes to demolishing a building.
