Is exterior siding applied directly to the panel skin?
Most type of type of cladding can be applied to the panel (acrylic stucco, vinyl and metal are applied directly to the panel). As an alternative, the panel’s outer skin can be supplied in weather resistant surface. In that case surface finishing resembles wooden siding and it does not require any additional siding. Felt paper and other moisture barriers need not be used between the panels and siding.
