US Patent:

Filed:

Feb 18, 1992

Appl. No.:

7/837266

Inventors:

Brian S. Alexander - Westfield IN
Daniel L. Barksdale - Brownsburg IN

Assignee:

Bridgestone/Firestone, Inc. - Akron OH

International Classification:

A61F 1302

US Classification:

428 40

Abstract:

A laminate cover for sealing an opening in a weatherproof roofing membrane includes a top sheet of a weather resistant material, preferably an uncured butyl rubber EPDM material, and a complementary shaped and sized lower sheet of a lightly cured butyl rubber having opposed tacky surfaces. A layer of a flowable sealing material such as an uncured butyl rubber sealing compound having a smaller dimension than that of the lower sheet, is trapped between the lower sheet and a bottom release coated carrier. Upon removal of the carrier, the cover is pressed over the opening to be sealed and an exposed peripheral tacky area of the lower sheet secures the cover to the membrane and traps the sealing compound therein. Applied or ambient heat will cause the sealing compound to flow into the opening to effectively seal the same, and will vulcanize the top sheet to provide abrasion and weather resistance for the cover.
