The Forestlines facade system combines untreated wood with an intelligent aluminum profile. This combination ensures an extreme optimization of flammability. Untreated wood is the raw material of the past, but above all of the future. Untreated wood unfortunately has one major drawback, which is its flammability. Solving this issue was a grueling task with a wonderful result. The European test method (SBI test) indicates that this is the very first facade cladding with untreated wood, which can achieve fire reaction class B. A fire reaction class that was impossible until Forestlines.
