Abstract: The system is for covering an existing building to finish particularly the exterior face of the building. Pre-fabricated panels with windows previously installed are secured within an existing window opening with the primary attachment for each panel being only at the window opening. Each panel comprises interconnected studs and bridging forming a frame having supported therein fiberglass insulation. Adjacent panels are sealed therebetween by a caulking bead. The panel is supported from the existing window opening by bracing at the top and sides.

Abstract: A building wall panel includes vertical studs welded to top and bottom channels to provide a rigid framework the maximum width of which is such that the panels may be transported over highways and the length of which is determined by the wanted wall height. Finish sheet material is secured to the inner or rear surfaces of the framework to provide an inner wall. Sections of insulating material are lodged in the rectangular spaces of the framework against a vapor barrier backed by the inner wall and dimensioned to be spaced from the outer surfaces of the framework. A vertically spaced, series of horizontal sub-girts has one secured to each channel and others secured to the studs and the sub-girts secured and the channels may be used to secure flashing. Metal panelling is secured to the sub-girts to provide an outer wall thus providing the panel with a dead air space. The framework is modified to meet door and window requirements.
