Timber Housing Construction Quality Mark

The Timber Housing Construction quality mark (RAL-GZ 422) is based on the construction product certification of wooden panel elements. These are produced off-site in the production facilities of the member companies and are sheathed on one or both sides. The quality of the individual elements of the walls, ceilings and roofs of off-site manufactured houses is improved by the companies’ factory production control and the external monitoring by the BMF. In addition to the factory monitoring, the erection or assembly of the building is also monitored randomly during the building shell construction stage on site.
