The basis for a new generation of innovative wood products has been developed in the InnoFireWood project. The main characteristics of such products are substantial improvements in fire performance with maintained eco-efficiency, durability, and other properties of the original wood product. Industrial relevance, sustainable production, and end-use applications were in main focus. This type of products will increase the competitiveness of wood products in relation to other building products. A new Nordic system with classes for the Durability of the Reaction to Fire performance (DRF classes) at interior and exterior building applications has been implemented in order to assess the overall sustainable performance of the new products. The project was conducted in close co-operation between Sweden and Finland. In addition to research institutes, industry was represented by several companies producing wood products or fire retardants.
