EXTERNAL HEAT INSULATING STRUCTURE OF BUILDING

PROBLEM TO BE SOLVED: To provide an external heat insulating structure easily and inexpensively constructible on the roof of a concrete building. SOLUTION: A waterproof material is applied onto the surface of a roof skeleton 1 of the concrete building to form waterproof layers 2, 3, and a protective material for protecting the waterproof layers 2, 3 is laid on the upper face of the waterproof material to form a protective layer 4. Further, granular foam glass materials 5 of predetermined size are laid as a heat insulating material on the upper face of the protective material to form a heat insulating layer 6. The foam glass materials 5 spread all over the roof are covered with a scatter preventing member 7. COPYRIGHT: (C)2005,JPO&NCIPI
