Phase Changing Materials (PCM): Risks and Opportunities.
There are different types of phase changing materials and it is mainly the organic materials that constitute a challenge from a fire safety perspective. Organic phase changing materials, paraffin being a commonly used material, are in general combustible. Swedish building regulations are material neutral and takes into account the possibility for combustible building material and there is therefore no immediate need for revisions of the regulations due to these materials. However, the building process will be more vulnerable to mistakes and errors if new combustible materials are introduced into buildings.
