New generation glass wool from ISOVER

With a 100% bio-sourced binder, this new patented material is soft to touch, light to handle, and easy to cut. The glass wool combines high acoustic and thermal performance, while also improving interior air quality and generating considerable energy savings.

The new ISOVER glass wool is manufactured using mineral materials – recycled glass accounts for a minimum of 40% – and 100% bio-sourced binder. It is infinitely recyclable. What’s more, when used to insulate the walls and roof of a house, it can reduce carbon emissions from heating by 40%, that is 150 metric tons of carbon over the lifespan of a building or the equivalent of one million kilometres travelled by car.
