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.

Dependent claims

A high elongation ridge ventilation sheet for a sloping roof, comprising

two folded composite aluminum membranes, each of the folded composite aluminum membranes comprising three layers in a bottom up sequence of a PET polyester membrane, an aluminum foil, and a polyurethane layer,
a coated composite aluminum membrane, the coated composite aluminum membrane having multiple circular holes and comprising in a bottom up sequence of a polyurethane layer, an aluminum foil, and a PET polyester membrane,
a butyl adhesive tape for central linking being coated on a curved line of a side of the polyurethane layer of the coated composite aluminum membrane, the butyl adhesive tape being bonded with the PET polyester membrane of the folded composite aluminum membranes,
a polyester nonwoven fabric covering the whole coated composite aluminum membrane, and
a hot melt adhesive being arranged on a surface of the polyurethane layer of each of the folded composite aluminum membrane adjacent to the coated composite aluminum membrane for connecting the polyester nonwoven fabric with each of the folded composite aluminum membranes.
