Abstract
A heat insulating structure comprising a vacuum insulator fixed to a surface on which the vacuum insulator is to be applied is provided for the purpose of improving the workability in fixing the vacuum insulator to the surface to be applied. A thermally adherable layer comprising a thermally adherable material is made between the vacuum insulator and the surface to be applied, and the thermally adherable layer is heated and melted whereby the vacuum insulator is fixed to the surface to be applied.
Claims6
A heat insulating structure having an outer wall with an internal surface, said insulating structure further comprising a vacuum insulator and a fixing device having an adhesive strip thereon,
- said vacuum insulator comprising polyurethane insulation material inside thermally sealed gas barrier films of polyethylene or polypropylene;
- said fixing device being separate and distinct from said outer wall of said heat insulating structure before said fixing device is fixedly secured to the internal surface of said outer wall of said heat insulating structure by said adhesive strip, said fixing device being rigid and having side walls forming a cavity into which peripheral parts of said vacuum insulator are retained.
