Circular insulation product made from waste. The innovative EverUse insulation material is upcycled from waste paper and cardboard. A woolly material is created by shredding these natural cellulose fibres. Because the circular product is upcycled from waste instead of virgin raw materials, it has a negative CO2 footprint and stores CO2 in the construction in which it is incorporated. The natural cellulose fibres are gentle on the skin and not harmful to the respiratory system. It contains no harmful fibres or toxic substances such as formaldehyde and ink. This makes it possible to create healthy acoustic furniture applications that contribute to a healthy and responsible working environment. EverUse is the world's first circular insulation material with Cradle to Cradle certification.
