What Is Cork Spray?


After it’s harvested from the outer bark of the cork oak tree, cork can be processed into all sorts of useful products. This includes cork spray. Homeowners and business owners throughout the U.S. are increasingly using sprayed cork coatings because they offer energy efficiency, acoustic insulation, and many other functional benefits. Cork spray products manufactured by ThermaShield in Texas are designed specifically to reduce the carbon footprint of a building while enhancing its aesthetic appeal.
