ABSTRACT:

FIELD OF THE INVENTION
This invention relates to thermally efficient construction. More particularly this invention relates to a method of construction which produces an air tight structure which is capable of being insulated to high R values.
BACKGROUND OF THE INVENTION
Conventional residential construction uses framed exterior walls which comprise a single row of 2×4 or 2×6 studs. The insulation which can be stuffed into the wall is limited by the width of the studs. Above door and window openings headers are required for structural strength and there is no room for insulation. The exterior walls also contain electrical outlet and switch boxes which are interconnected with wire cables. When the wall is covered with an air impervious sheeting it cannot be made air tight because of the openings in its face which must be made for the electrical outlet and switch boxes. Sometimes the exterior wall contains water lines, Because of the inadequate insulation between the walls exterior side and the water lines, freezing of the water lines may be a problem.
As a result of both environmental concerns and reducing heating and cooling costs many individuals have demanded more energy efficient construction methods. The typical house has a total recirculation of air through its exterior a multiple number of times per day. In addition to using more insulation, reducing the total recirculation of air through the closed home is a major focus of concern.
One method of making a house more air tight comprises enclosing the electrical outlet and switch boxes with an air tight shroud. However the problem with this approach is that the shroud must be penetrated by interconnecting electrical cables.
What is needed is a simpler and more effective method of sealing the home. A method which will facilitate better insulation of the house particularly in the critical heat loss areas above doors and windows. And a method which will eliminate exterior air seepage through electrical switch and outlet boxes.
OBJECTS OF THE INVENTION
It is an object of this invention to disclose a method of framing construction which results in a substantially more air tight structure. It is an object of this invention to disclose a method of framing which facilitates more adequately insulating walls. It is an overall objective of this invention to disclose a method of construction which will culminate in a substantially more thermally efficient structure which will have substantially reduced heating and cooling costs. It is yet a further object of this invention to disclose a simple and effective method of framing which uses standard materials in standard and familiar ways. A method which framers will be able to readily adapt to with minimal learning time and with minimal investment in inventory.
One aspect of this invention provides for 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. 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.
Various other objects, advantages and features of this invention will become apparent to those skilled in the art from the following description in conjunction with the accompanying drawings.
