Cost-effective method to estimate fire protection treatment status on existing facades
Wood is a climate-smart building material that can reduce carbon emissions, but it is also flammable and therefore requires special fire safety. Fire protection treatment can reduce the risk of fire spreading and make it possible to have more visible wood in buildings. The problem is that we know too little about how well these treatments last over time, especially outdoors. Tests show large differences between different systems and laboratory tests do not always match reality. In addition, there is no good way to check whether the fire protection works after the facade is built – often it is necessary to destroy parts of the building to test.
