Building Wall Assembly

Abstract

A building wall assembly includes a panel of foamed polymeric material and studs received in channels at the inner side of the panel such that only an outer portion of the stud fits in the channel and an inner portion of the stud projects from the panel to define a utility space at the inside of the panel. Wooden structural sheathing material is joined across an upper portion of the studs at the inner side. Auxiliary sheathing material, for example concrete board, spans the outside of the panel in connection with strapping members recessed into strapping channels at the outside of the panel in which each strapping member is fastened through the panel to a respective stud. The studs may be wooden. Alternatively metals studs are used with utilities apertures therein so that spray foamed material can be connected between opposing sides of the stud channel through the utility apertures.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a wall assembly for use as an insulated wall in a building, and more particular the present invention relates to a wall assembly including studs which are recessed into rigid panels of foamed polymeric insulating material.BACKGROUND[0002]Various examples of wall assemblies for buildings are known in the prior art for being easy to assemble and for providing optimal insulation to the completed building. One common form of insulation is the use of a polymeric foamed panel. As described in U.S. Pat. No. 6,421,972 by Dalphond et al, insulating panels of this type may be used to form a continuous outer layer along an outer side of studs used in a structural wall to provide a thermal break on one side of the studs. No means are provided on conventional polymeric foamed panels for improving the insulation in the space between adjacent ones of the studs.[0003]U.S. Pat. No. 5,265,389 by Mazzone et al and U.S. Pat. No. 5,943,775 by ...

AI Technical Summary

Benefits of technology

[0014]In some embodiments, each stud comprises a wooden stud abutting the structural sheathing material. The combination of wooden studs which are only partially embedded into foamed polymeric panels results in a simple low cost construction which is easy to manufacture and install.

[0015]The simple profile of any rectangular studs in particular allows the studs to be readily slid into the respective channels in a direction perpendicular to the plane of the panel instead of the more awkward vertical sliding of metal channels into a foamed pa

Problems solved by technology

No means are provided on conventional polymeric foamed panels for improving the insulation in the space between adjacent ones of the studs.

Due to the complex cross section of the studs however, the construction of the panels to surround the studs is complex and expensive.

Furthermore, the space between the studs is typically filled with material when the studs are imbedded into the foamed material such that there is little or no access for running utilities such as electrical or water lines in the spaces between the studs as desired in conventional construction techniques.

In one embodiment of U.S. Pat. No. 5,943,775, the studs are
