Geolam is a sustainable wood-plastic composite used primarily for decking and cladding. Made of 90 percent recycled materials and 100 percent recyclable, Geolam is an ecofriendly wood alternative and a sophisticated choice. Geolam technology reduces moisture content of wood fibers to 0 percent, producing a durable, slip-resistant compound protected from warping, mold, and color fading.
Thanks to its quality and exceptional lifespan, Geolam has become the leading global brand in the field of wood-plastic products and offers the most durable, aesthetically pleasing and eco-friendly building material available. The need for sustainable building materials continues to grow and after thirty years of success in Asia, Geolam is finally available in the United States and Canada.
Geolam is gaining recognition as one of the success stories of the Green Revolution: a sustainable material for the future of construction.
