Method of insulation and framing

A method of framing and seating an exterior double wall on a supporting structure comprising the following steps:

• erecting an inner wall having a footer, a top plate, and spaced upright studs, along an inner edge portion of the supporting structure;
• covering the exterior side portion of the inner wall with a vapor barrier so that electrical wiring and plumbing may be run within the interior wall without penetrating the vapor barrier;
• erecting an outer wall having a footer, a top plate, and spaced upright studs along an outer edge portion of the supporting structure parallel to and spaced from the inner wall, said outer wall used to carry an exterior building wall covering after insulation which is positioned between the walls and between the studs of the outer wall;
• and,
• erecting a supported structure on top of the top side portion of the walls;
• and if that supported structure includes trusses then the vapor barrier is extended over the top portion of the inner wall before the supported structure is erected thereon, so that the vapor barrier may be subsequently tied into a vapor barrier on a lower side portion of the truss;
• and if the supported structure is an upper platform for an upper floor, then the vapor barrier is extended over the top portion of the outer wall before the upper platform is supported thereon so that the vapor barrier may be subsequently extended around an edge portion of the upper platform and tied into a vapor barrier on an exterior side of an inner wall carried on the upper platform.
