Abstract: The present invention is an insulated modular wall system for quickly and efficiently constructing buildings of one or more stories. Included in this modular wall system is a plurality of building pans, each having a pair of flanges for interlocking adjacent building pans. Some of these flanges are configured to compensate for dimensional variations that are inherent in each of the building pans. If not compensated for, these dimensional variations can result in excessive stress when a plurality of adjacent building pans are interlocked. Included in the invention is a unique method for supporting convention floor boards, and a unique arrangement for creating a gap for electrical wires and the like.

Abstract: A double-glazed window frame comprising two parallel glass panes has an internal blind disposed between the glass panes in parallel therewith. The internal blind comprises a succession of collapsible elongated tubular volumes formed from a plurality of plastic strips; each plastic strip having a center section, an upper face, a lower face, an edge adjacent one of said glass panes and another edge adjacent the other of said glass panes; with the plastic strips alternately bonded to one another through the center section and through the two edges. Each plastic strip has a metallic layer deposited on each face thereof, and each metallic layer has a break in continuity between the edge adjacent one of the glass panes and the edge adjacent the other of the glass panes, whereby the coefficient of thermal insulation of the blind is improved.

Abstract: A multi-use metal building comprises a skeleton composed of vertical posts connected to upper and lower horizontal longitudinal girders, thus forming a frame ensuring transverse and longitudinal stability.In the horizontal plane, the skeleton comprises self-supporting metal trough elements modulated to the same width as the posts, with corrugated cross section, these trough elements resting on the upper longitudinal girders of the frame and serving on the one hand as floor support and on the other hand as roof.The vertical walls (posts, upper and lower longitudinal girders, outer skin made of asbestos and inner insulating partition) ensure the vertical stability in both directions.
