1973 - 1st generation
Composite wood was invented in 1973 by Nishibori Sadao, an importer in tropical timber. Over 43 years ago he found his inspiration on a trip through the forests of Indonesia, where he had seen at first hand the consequences of widespread and uncontrolled deforestation. For a cultured and educated Japanese gentleman, who was raised in the Shinto tradition with a profound respect for nature, it was a shock. Nishibori Sadao then totally dedicated himself to the invention of a tropical wood substitute, more respectful of the environment: the wood composite.
First generation Geolam products were heavy, solid decking products. But in 1992 a production method developed by Japanese engineers led to the manufacture of the world’s first hollow cell profiles and their typical honeycomb structure. Hollow cell boards are lighter, more efficient and absorb much less water than solid decking products used before 1992. Their cross sections can be selected to permit substantially larger spacing between joists in the substructure. The stability and ease of assembly provides, for this second generation, profiles which enable fast installation in larger properties and public sector construction projects.
Geolam outclass this old generation compact technology with its revolutionary micropore technology. Combining the polymer with the micropore technology led to the creation of the unique patented building material, the Premium Micropore WPC. The patented co-extrusion production process enables micro cells to fuse with coatings. This brings completely new properties to the profiles. The new micropore technology decreased the density of the profiles from 1270 kg/m³ (first generation WPC) to 750 kg/m³.
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.
