As the first and only provider, Geolam started offering under the name of Wood Hybrid Systems (WHS) its exclusive range of profiles for façades, decks and roofs to the global marketplace in 2012. These WHS profiles are the result of an innovative hybrid technology, which enables heterogeneous materials to be successfully extruded together under heat. Three layers of different materials undergo our patented triple extrusion process. Light, stable aluminum (aluminum 6063T5) makes up the core.
