NovaCork panels are ultra-tackable interior panels that are completely finished and require no surface treatment. The top layer is a sheet of cork "planks refuses" laminated to 440 Homasote®.

NovaCork is perfect for homes, schools, offices, and hospitals, wherever large tackable bulletin-board areas are needed.

Energy-saving, NovaCork panels are noise-deadening, while providing extra insulation when used to panel peripheral walls or ceilings. These large, structural sheets are available in Class B 4' x 8' square edged panels.

NovaCork panels may be installed directly to framing with nails or APA-approved paneling adhesive by glue-nailing. For a professional finish apply high-quality millwork or extruded aluminum trim and joint molding.

Material Composition

NovaCork paneling is composed of three basic elements: a cork veneer surface, bonded to a substrate of Homasote® structural building board, with a non-toxic, non-VOC adhesive. Homasote is uniformly manufactured to with protection against termites and resistance to mold, mildew and moisture.
