These are the thickest raw natural cork bark tiles that are available. They are approximately 1.4 inches thick. These tiles are attached under high pressure to a flat and smooth cork panel allowing easy mounting on the wall. They can be glued or nailed to the wall. They are easy to cut as they are made from cork. I work directly with cork farmers in Portugal. Portugal produces the best cork in the world. These tiles are individually hand crafted from cork bark, the first stripping of the cork oak trees. These 3D cork bark tiles are naturally dramatic, rich in texture, warm and as durable as Mother Nature meant bark to be. As with all cork coverings, virgin cork tiles also provide good insulation and improve acoustical values. They are available in the following approximate sizes: 300mm x 300mm x 35mm in size (approximately 12" x 12" x 1.4"), 600mm x 300mm x 35mm in size (approximately 24" x 12" x 1.4"), 900mm x 600mm x 35mm in size (approximately 36" x 24" x 1.4").

It is light weight, rot resistant, non-toxic, good compression and expansion, fire resistant, impermeable, soft, and buoyant. Cork bark is "stripped" off the cork oak trees at appropriate intervals without damage to the trees and allows new bark to grow in its place so there is no harm to nature, no trees are cut or destroyed, no disturbance of flora and fauna. I can also cut them into any size you would like.
