Project: Wood-based thermal insulation mate

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, because of fibreglass materials have high embodied energy amount and foamed plastic insulation materials are oil-based. In addition, fiberglass fibres can be harmful when they are inhaled and the used spraying chemicals for foamed polyisocyanurate and polyurethane are hazardous for health before curing has occurred. Cellulose is the oldest building insulation material. In the history of buildings many types of cellulosic materials have been used, including newspaper, cardboard, cotton, straw, sawdust, hemp and corncob. Recently cellulose insulation has again increased in use. Part of the reason for this growth is related to increased interest in green building. Cellulose has lower environmental impact and higher recycled content compared to mineral and synthetic polymer based materials. 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-like structures. Foam forming technology adapted from other industries will be used for manufacturing high performance cellulosic thermal insulation panels. WotIM aims to develop cellulose based spray foam material which is as easy to be sprayed in-situ at construction site as polyurethane spray foam.
