## Abstract

A high elongation ridge ventilation sheet for a sloping roof, having a coated composite aluminum membrane with multiple circular holes, each side of the coated composite aluminum membrane being bonded respectively with a folded composite aluminum membrane via a butyl adhesive tape for central linking, on a side of each folded composite aluminum membrane adjacent the coated composite aluminum membrane is arranged with a hot melt adhesive for connecting a polyester nonwoven fabric with each folded composite aluminum membrane, with the polyester nonwoven fabric covering the whole coated composite aluminum membrane. Further, a fabricating method therefor that realizes wholly dry construction; ridge ventilation sheets adopted on ridge locations not only make the whole roof prettier, but more importantly, enable air convection under the roof in a true sense, taking out extra dampness and heat, resulting in better energy saving effects, and extending life span for the roof.
