In this project superior cellulose based insulation materials are developed. The insulation properties are enhanced by creating air pockets to the cellulose material matrix by foam or foam-like structures. The target is that the performance of the novel cellulosic insulation materials is at comparable level with the materials made of polyurethane foams.

Fibreglass is the most widely used insulation material worldwide and growing. A steady growth is expected as well in the foamed plastic insulation segment because of their high insulation values. From environmental and sustainability point of view this trend is very worrying. Foamed plastic insulation materials are oil-based and therefore not ecologically sustainable materials. In addition, the used spraying chemicals for foamed polyisocyanurate and polyurethane are hazardous for health before curing has occurred.

Cellulose has the highest recycled content of any insulation material and also has less embodied energy than furnace produced mineral insulation materials. According to the evaluation of Thermal Insulation Manufacturers and Suppliers Association (TIMSA), polyurethane foams had the highest and cellulose insulation materials the lowest environmental impact of different insulation materials.
