For many years, wood has been the most ecological raw material with many advantages.
It is a renewable raw material, stores CO2 and much more.
Unfortunately, product developers keep coming up against its biggest Achilles' heel, its flammability.
Although there are ways to treat wood with a fire retardant, we did not believe in this ourselves and decided to only work with the untreated natural product.
After years of scientific development process of trial and error, the Forestlines® façade system was developed.
A revolutionary, circular system that is the very first in the world to bring untreated wood as the most ecological raw material to fire reaction class B in END-USE in accordance with EN 13501:1-2018.
If you take into account that the average calorific value of one kilogram of wood is 15.5 MJ (houtinfo.nl), this means that to achieve fire reaction class B, you can burn a maximum of +- 500 grams of wood after ten minutes in a fire of 800 degrees Celsius.
Although the letters are right next to each other in the alphabet, there is a world of difference!
Whereas with B you burn a maximum of 500 grams of wood after 10 minutes, with a fire reaction class D there is not much left of the test set-up.
Our system optimizes each type of wood to its maximum potential.
How high it can end up depends of course on how low it starts.
We will also improve cardboard, but of course we cannot achieve reaction to fire class B with this.
In general, untreated wood is usually equated with fire reaction class D.
Some combinations of profiles and types of wood may be able to achieve a fire reaction class C, but these are rather rare.
There are also several combinations that themselves do not reach the (very) low-threshold fire reaction class D.
