A New Useful Improvement. An encapsulation method for producing high quality low cost housing panels, which uses commercially fabricated pre-assembled light gage steel framed structures, with superior insulation material. The encapsulation process uses a Clamshell Jig Fixture designed specifically for this process. The pre-assembled steel housing frames are placed in the Jig Fixture and sealed. Thereafter the insulation material is injected into the steel framework via openings in the jig fixture. The insulation material is a high density Class 1 Isofoam Polyisocyanate, known as Polyurethane. It is free of Formaldehyde and CFC's or HCFCS. Its insulation "R" factor is 7.69 per inch of thickness. Finished panels result in "R" factors to 40.37, with vertical, horrizontal, wind and seismic strengths greater than building code requirements for housing. Panel attaching methods are simpler and stronger using smaller, short, light 16 to 12 gage studs, bolts, nuts and anchor plates.

[ What is claimed and desired to be secured by letters of Patent is as follows:] [1.]1. A method of encapsulating single open frame light gage steel panels, which comprise the following steps:(a) Taking a pre-fabricated, pre-assembled, light gage steel framework panel, that meets applicable structural building codes, with pre-installed electrical components, raceway and outlet boxes, and basic plumbing requirements;(b) Placing the pre-fabricated steel framework into a predesigned Clamshell Jig Fixture;(c) Positioning the framework in such a way as to allow for a 5/8 inch gap on one side of the panel and 1.00 inch gap on the other side of the panel, using selected spacers;(d) Installing into the jig fixture a door or window filler if required in the panel design;(e) Installing teflon attaching hardware fillers;(f) Closing the Clamshell which is self sealing;(g) Inserting a polyurethane injection wand from a injection machine, into the closed Clamshell in the required injection hole openings;(h) Turning on the injection machine and injecting the two part foam into the Clamshell, filling all the vacant or open internal areas with the foam;(i) After the polyurethane foam is cured, approximately 3 to 5 minutes, remove the encapsulated panel from the Clamshell;(j) Last, trimming off any amounts of excess foam from the panel, which is a finished polyurethane foam panel.
