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

Patent number: 6134856Abstract: An improved roll roof membrane for use in commercial applications, i.e., flat and low pitch roof structures, and a method for the preparation thereof. The roof membrane comprises a support sheet, and top and bottom layers comprising APP modified bitumen, the top APP modified bitumen layer having a selvage edge disposed along one side of the membrane and the bottom APP modified bitumen layer having a second selvage edge disposed along the opposite side of the membrane. Each of the selvage edges have a series of embossed ridges and valleys adapted to accept adhesives, the valleys extending substantially through the APP modified bitumen layer to the support sheet. The membrane exhibits excellent peel strength with an adhesive, thereby eliminating the need to use a torch during installation in commercial roofing applications.Type: GrantFiled: February 5, 1999Date of Patent: October 24, 2000Assignee: Building Materials Corporation of AmericaInventors: Amir G. Khan, Joseph R. Bruns, Richard Darrell Rains, Michael Di Stefano

Patent number: 5848510Abstract: An improved base sheet for a roofing assembly wherein the base sheet is perforated with a plurality of apertures characterized by non-cylindrical cutouts in the shape of a closed figure or a polygon having at least two sides or boundaries of unequal length which aperture configuration permits strong attachment of the sheet to a substrate without the aid of auxiliary attachment means and without weakening of the base sheet structure.Type: GrantFiled: February 4, 1997Date of Patent: December 15, 1998Assignee: Building Materials Corporation of AmericaInventors: Brent L. Grazman, William J. Woodring

Patent number: 5657602Abstract: An exterior wall system for a side of a building includes a plurality of prefabricated composite panels which are positioned in courses above an elongated support bracket attached to a support structure of the building, the composite panels being connected to the building support structure by fasteners which extend through washers that each extend in part into grooved channels in the sides of abutting panels from adjacent courses. The courses of panels are covered by a seamless layer of a hardened mixture of binder and aggregate material such as marble.Type: GrantFiled: February 6, 1996Date of Patent: August 19, 1997Inventor: Leif H. B. Hellander

Patent number: 4680907Abstract: A building material for cement based facing such as stucco and brick facing. A thin layer of water impervious epoxy is applied to one side of a wallboard or plywood sheeting. Sand is imbedded in the epoxy in a manner to fully cover the epoxy. The sand surface provides a compatible bonding surface for stucco and mortar which are then applied in a conventional manner.Type: GrantFiled: October 28, 1985Date of Patent: July 21, 1987Inventor: Richard D. Williams

Patent number: 4425746Abstract: A roof structure wherein a water impermeable membrane is fabricated upon a roof deck and a thermal insulation layer affixed upon the membrane. The insulation layer is thereafter coated with a suitable adhesive material and particles of inorganic particulate attached thereto, whereby a toothing surface is formed upon which is applied a mortar based insulative-protective layer. Alternatively, and in lieu of said mortar based layer, a first water impermeable layer formed of bituminous material may be disposed upon said toothing surface, followed by disposition upon said first layer of a second water impermeable layer formed of elastomeric material having radiant energy reflective material admixed therewith. Optionally, said first layer may be omitted from the roof structure and said second layer placed directly on the toothing surface.Type: GrantFiled: June 15, 1981Date of Patent: January 17, 1984Inventor: Orland H. Bonaguidi
