Method for improving the thermic insulation of a building with a rigid frame structure

Claim 1

The improved method for thermally insulating a building having a rigid metallic frame comprised of columns, beams, braces and rafters rigidly fixed to each other and designed to support sheet metal roof and wall panels which are bolted or similarly secured thereto, said method comprising the steps of: placing a thick layer of insulating material onto the inner surfaces of the roof and wall panels before they are secured to the metallic frame, and then securing said panels to said frame, said layer of insulating material being compressed and pinched between the roof and wall panels and the parts of said rigid metallic frame to which they are fastened; and subsequently completing the insulating of said building by gluing rigid coverings made of insulating material onto every column, beam, brace and rafter of said rigid frame, said rigid coverings being previously cut and shaped so as to completely cover the visible portions of said rigid frame appearing within said building under the layer of insulating material pinched between said frame and said roof and wall panels when the building is assembled, and said rigid coverings being in engagement with and being glued to said layer of insulating material whereby an essentially integral insulating layer is provided within the building.
