How is the Winnebago Revel 4×4 Insulated?

Winnebago Industries partnered with a supplier of Automotive Grade foam for insulation on the New Winnebago Revel. Considered “best practice” in automotive, trucking, and other vehicle industries this insulation is used by Chrysler, Ford, GM, and Mercedes Benz. The material has R-value of 4.4 per inch of thickness which the foam will provide this value for the lifetime of the Revel under all environmental conditions. Engineered to reduce noise and thermal insulation, meets automotive fire and safety standards.  A healthier insulation is not susceptible to moisture retention or mold and does not block drain holes like spray foam which could cause unwanted odors.

The wall construction of the Revel has 37mm foam that is CNC (computer numerical control) cut by water jet to precisely form to the openings in the body of the base vehicle. The interior walls have ABS plastic panels spaced 19mm from the inner surface of the van walls. These panels have 19mm of insulation bonded to them. The inner wall panels form a vapor barrier to prevent drafts from the outer skin of the Revel from reaching the occupants.

Engineered in Europe the dual pane acrylic awning windows are for hot and cold RV weather use. The Revel aluminum frame system includes a frost break and top-hinge design allows usage in light rain.  Integrated reflective shade system with fly screen provides additional insulation value.  Winnebago Revel floor construction consists of plywood and expanded polystyrene foam laminate. Solid floor, good screw retention provides a thermal break between the interior and floor of the Revel.

The Revel uses a double-wall roto-molded water tank system. The void between the inner and outer walls is filled with 19mm automotive grade insulation. Glycol lines returning from the interior coach heat exchangers are routed through the fresh water tank enclosure and then around the gray tank dump area on their way back to the heating unit.
