Abstract
Abstract A modular structure for constructing building walls for domestic and commercial housing including inner and outer panels interlocked at the edges by dovetail grooves and retained in spaced relation by wire grills engaged with the edges of the panels. An insulation block is provided, to span a single panel or multiple panels, and positioned against the inside surface of an inner or outer panel. This block is located by individual rods of the wire grills and retained in position by said rods. Multiple blocks, face to face, can be utilized to increase the insulation factor as desired.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
107 words
In combination, a modular structure composed of spaced parallel panels which are assembled in situ with rigid rod grids spanning the space between said panels interlocked with the edges of the panels and recessed and lying within the planar geometric confines of said panels, and preformed insulation lodging against an inner surface of a least one of said panels in said space comprising a form sustaining block of insulation dimensioned and conforming to the planar dimensions of said panels and having edge grooves transverse to the planes of said panels and receiving portions of said rigid rod grids and positioning block against said one of said panels.
Claim 2
Dependent Claim
