Patent number: 6531200Abstract: A roofing membrane material is disclosed. The material is characterized in that it includes a woven or non-woven fibrous mat encapsulated within a non-adhesive asphalt coating, the resulting encapsulated mat having an adhesive asphalt layer applied to one surface thereof. An acrylic coating is applied to the surface of the encapsulated mat that is not in contact with the adhesive asphalt layer. The resulting membrane, when applied to a roofing deck, provides a high traction surface that will not adhere to shingles and provides an effective waterproofing seal on the roofing deck.Type: GrantFiled: May 20, 1999Date of Patent: March 11, 2003Assignee: Northern Elastomeric, Inc.Inventors: Thomas Zickell, James Karlis, Charles Diamon
