SinoCore® is a composite panel made by laminating either textured or smooth prefinished aluminum skins to a core of high density polypropylene.A second aluminum skin is added as a backer and provides panel balance. Panels are furnished with a strippable film (or interleafed microfoam) on the painted surfaces to protect the finish during shipment and installation. SinoCore® is attached to the substrate using either mechanical fasteners or construction adhesive, depending upon the method selected. Joints are finished using one piece or two piece extruded aluminum trim moldings.
