Life cycle of glass wool

Isover glass wool is a product made in France made from 80% cullet (recycled glass), sand and the rest made from natural materials. These elements are grouped on three production sites (Chemillé, Chalon-sur-Saône and Orange) where they are transformed before leaving in rolls of glass wool, packed in hyper-compressed volumes in order to further reduce the costs of transport and the environmental impact.

Cullet, sand and natural additives are passed through furnaces that bring the glass into fusion, to which a binder and fibers are added.
At this point, the product is parboiled and, cut to size, it passes to the winder where it is highly compressed and packaged. It is then put on pallet for storage and transport.
The Isover production sites are ISO14001 certified (environmental certification). Glass wool has a longevity estimated at about fifty years. It is 100% recyclable.
100 000 craftsmen put it at the length of construction site where it allows to save energy 200 times higher than that spent to manufacture it.
