Claim 1
Independent Claim
133 words
An outer heat-insulating structure on a building roof, comprising heat-insulating boards arranged longitudinally and laterally on the upper surface of a building body, and hold panels arranged longitudinally and laterally over the heat-insulating boards while a spacing is provided therebetween, said adjacent hold panels being joined together by means of support legs, fixing caps at the corner portions of the hold panels, and means connected at a peripheral portion of the outer heat-insulating structure provided with openings to establish communication between said spacing and outside said structure; whereby during a condition of strong winds above the hold panels, a difference in pressure beween above and below the hold panels is mitigated due to the openings establishing communication between said spacing and outside said structure thereby preventing the peeling off of the hold panels.
