Title: Housing panels, encapsulated, steel framed

Abstract: A New Useful Improvement. An encapsulation method for producing highquality low cost housing panels, which uses commercially fabricatedpre-assembled light gage steel framed structures, with superior insulationmaterial. The encapsulation process uses a Clamshell Jig Fixture designedspecifically for this process. The pre-assembled steel housing frames areplaced in the Jig Fixture and sealed. Thereafter the insulation materialis injected into the steel framework via openings in the jig fixture. Theinsulation material is a high density Class 1 Isofoam Polyisocyanate,known as Polyurethane. It is free of Formaldehyde and CFC's or HCFCS. Itsinsulation "R" factor is 7.69 per inch of thickness. Finished panelsresult in "R" factors to 40.37, with vertical, horrizontal, wind andseismic 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.
