After cork bark, the wood used to make wine bottle corks, is plugged, it may be fashioned into a durable, high-density slab called Suberra by the Eco Supply Center in Richmond, Virginia. This company has compress post-industrial recycled cork grain with a polyurethane binder to create 1-1/4 inch composite slabs, 25-1/2 inches wide by 36-1/2 inches long.
Cork is made from Cork Oak bark which regenerates hastily. It is composed of suberin, a water-repelling and waxy substance. Suberra gets its name from this substance.
The material may be installed using woodworking tools and standard adhesives, according to the Eco Supply Center. Suberra may also contribute to LEED in the renewable, recycled content and no-added urea formaldehyde provisions.
According to lab tests, Suberra has a fire rating of Class B and a good resistance to stain and abrasion (except for mustard, ammonia and black shoe polish in raw, unfinished samples). Each slab weighs about 31 pounds and may be used to make vanities, tables, desks, kitchen islands, countertops, and other surfaces.
Suberra usually goes for about $250-$300 per slab.
