Delegated Act “Reaction to fire Paneling and Cladding” approved

The European Parliament recently approved the Delagated Act regarding the fire safety of wooden cladding. The most important change is that it is expressly stated that the CWFT table only applies to untreated wood. The CWFT table is a standardized solution (EN 14915) to declare wood under certain conditions in accordance with the accessible fire reaction class D for closed facade cladding. The CWFT table means a closed facade system (made of untreated wood) with a minimum thickness of 18mm and minimum density of 390kg/m3.

Fire classification

On November 10, 2023, the European Commission (EC) adopted a Delegated Act that no longer makes it possible to declare (closed) facade cladding made of modified wood, preserved wood or that has been provided with a coating as fire class D without testing. Only ''untreated'' wood and applied in accordance with the End-use application in the NEN-EN 14915 standard can be ''declared'' in the declaration of performance (Dop) that must be made without testing in the context of CE marking. The profiling must always be in accordance with table 1 below (based on NEN-EN 14915 table 1). The starting point is that the substrate behind the cavity has a minimum fire class A2-s1, d0 (the background on which the framework and facade cladding are attached).

NB! As of August 20, 2024, you will need proof of the performance that you declare in your Declaration of Performance (Dop) (such as fire class) for all facade cladding products, which is part of the CE marking.
