A plastic double wall panel is presented as a multi-functional purpose panel that can be laminated to any rigid or semi-rigid substrate to provide protection! waterproofing, bugproofing, drainage, solar heating, and/or an air transfer system, as well as offer a smooth surface for finishing or signage. The invention provides a component comprising of a plastic double wall sheeting that is an extrusion of 2 parallel walls which are connected by numerous flutes or channels, along its length, in a perpendicular or triangular pattern to form a rigid single panel. One side of the double wall panel may be slotted or perforated to create a drainage system. This allows liquid to pass through the perforated wall and drain along the flutes. The other side that is not perforated acts as a waterproof barrier or membrane. Also a cloth or material which allows liquid to pass through but not particles, may be attached to the perforated side to form a filter system. The plastic double wall panel can be laminated to any type of rigid or semi-rigid foam, such as extruded, expanded, polyurethane, or rigid polyisocyanurate foam (which is bonded directly during manufacture of the foam), to form an insulated protected panel, and/or part of an insulating concrete system. The length, width and thickness of the laminated foam panels can be varied to conform to different size specifications. The foam side of the concrete forming panels, facing the concrete, can be grooved along its length (vertical). This allows the cement to bond completely to the foam, eliminating the need for fasteners and creating an effective moisture barrier. the edges of the foam may have an interlocking design so as to form a continuous wall. The plastic double wall acts as a crush zone to protect the foam during backfill of a below ground wall as well as seals, waterproofs, and bugproofs the wall along with providing drainage, a solar heating, and/or an air transfer system. The plastic double wall panel also uses the inner airspace for added insulation affect.
