Electromagnetically shielding an enclosable structure having a floor, walls, a ceiling, and at least one closeable opening by applying a shielding wallcovering to at least a portion of one of the walls and applying a second type of shielding material to at least a portion of the enclosable structure, wherein the second type of shielding material differs from the shielding wallcovering. The shielding wall covering is wallpaper comprising a metal-coated broad good and a resin. Other types of shielding material may include a transparent, shielding window covering such as NiCVD coated screen of woven silk fibers; shielded flooring such as a layered combinations of Kevlar non-woven as a base layer, nickel-coated non-woven layers, and a PCF toughened polymer; and a transition shielding strip made of a base layer of the shielding wallpaper with a PCF toughened polymer coating over a portion of the strip.

A composite siding panel mountable on an exterior wall of a building includes a backing member and a siding member attached to the backing member, wherein the first side edge of the siding member overhangs the first side edge of the backing member, and the second side edge of the siding member also overhangs the second front side edge of the backing member. An adhesive coating joins the front face of the backing member to the rear face of the siding member. The adhesive coating runs substantially from the first side edge of the backing member to the second side edge thereof. In the field, the overhang on one side can be trimmed or removed as desired to make a siding assembly with the overhangs organized as desired for aesthetic purposes. A siding assembly including a plurality of composite siding panels adjacently mountable on an exterior wall of a building is also disclosed.

A thermoplastic composite sheet for exterior cladding applications includes an outer layer with a thermoplastic resin composition reinforced with a high aspect ratio filler such that the outer layer has a coefficient of linear thermal expansion of no more than approximately 2.3310.sup.5 in/in/deg F., and a backing layer bonded to the outer layer, the backing layer defined by a foam material. The outer layer and the backing later define a body having a substantially planar outer surface.
