Building with nature
GFM (Glue Free Massive) is a 30mm thick, mechanically connected, solid wooden board used for the panelling of wooden frame constructions.
The glue- and toxin-free GFM panels are suited perfectly for an ecologically oriented construction. The airtight quality of the GFM system is one of its special features. For the first time, you can build without using plastic sheets and adhesive tapes.
