Project: Fire protection of wood with bio-based wood modification

The aim of the project is to evaluate bio-based alternatives for fire protection of wooden facades and wood-based board materials. It is also to investigate how the fire retardants can be bound to the wood through modification and thus prevent leaching.

More about the project

Wood products without improved fire properties can be used as façade materials up to two floors and, to some extent, indoors. However, there are indications that the ongoing revision of the fire protection regulations will lead to stricter requirements, which will make it difficult to have large, visible, unprotected wooden surfaces indoors where the fire properties have not been improved.

When a higher level of fire performance is needed, it can be achieved by treating or modifying the wood. Conventional fire retardants for wood are problematic for several reasons. First, many fire retardants, such as boric acid and bromine and chlorine-based systems, have negative impacts on human health or the environment. In addition, many fire retardants are water soluble, which can cause problems with leaching when the material is exposed to high moisture levels and the fire protection decreases over time.

This project will develop new environmentally and health-friendly methods for fire protection of wood, based on bio-based molecules that are bound to the wood to prevent leaching.

The project is part of the research in the Forest Products research group and the Linnaeus Knowledge Environments Advanced Materials and Green Sustainable Development.
