Environmentally friendly intumescent flame-retardant solutions for exposed wooden façades and other exterior components in building construction

FR-Holz – Project start /

Wood is constantly gaining in importance as a natural and sustainable construction material for buildings. As yet, however, no satisfactory fire-protection solution exists for wood in exterior applications. A lack of flame retardancy is an exclusion criterion for wooden components in tall or large-scale buildings (building classes 4 and 5), unless an expensive and time-consuming approval is applied for in individual cases. In collaboration with our project partner, we are developing an environmentally friendly flame-retardant coating for wood which is exposed to the elements. This should not require an additional top coat and should be transparent when applied. As a result, we are helping to increase the utilization of wooden façades and other exterior components made from wood in the construction industry - for example in high-rise buildings, schools and hospitals.
