Cellulose fibre wool has been used as an insulating material for more than 70 years. It was first used in North-America. In recent decades it has gained large popularity also in Europe. In Finland it is the most popular blown loose wool.

The good thermal insulating properties of cellulose fibre wool are due to the fact that it is made of waste paper, the basic raw material of which is wood fibres. Wood fibres have suitable porosity and a high percentage of static air present between them.
