Abstract: A roofing membrane suitable for use as an underlayment comprising a flexible, non-woven mat of polymeric fibers which are substantially uniformly dispersed throughout the non-woven mat and thermally bonded together at the points of intersection by the polymeric materials of the fibers, the mat having a top side and a bottom side, a layer of an asphaltic material being disposed on the bottom side of the mat to provide a coated mat and a liquid parting agent applied to the top side of the mat.

Abstract: A self-adhesive ventilating modified bituminous roofing composite in which the release liner is printed with a transfer chemical such that upon removal of the release liner, the adhesive portion of the membrane is rendered non-adhesive in a pattern that provides ventilation pathways that allow for the lateral escape of pressure or latent moisture once the substrate is affixed to the roofing surface, thereby extending the life of the roofing system.

Abstract: Arrangement (1) for the permanent partial coverage of adhesive webs (7), particularly the coverage of self-adhesive webs (7), where a substance for covering the adhesive web is provided. The substance can take the form of a transfer substance, a covering lacquer (4), a covering film (4) or a similar material and can be provided on a substrate web (2).

Abstract: A roofing material having release tape having a substrate with adhesive capable of transfer from the substrate to the roofing material, and a method of producing same.

Abstract: A self-adhering modified bituminous roofing tile underlayment material for tile roof assemblies that comprises an APP modified bitumen compound on the front side, and a factory-applied self-adhesive compound on the back side of a reinforcement carrier sheet, and granules embedded on the APP modified bitumen compound to provide a non-skid surface.

Abstract: A self-adhering modified bituminous underlayment for metal roof assemblies that comprises an APP modified bitumen compound on the front side, and a factory-applied self-adhesive compound on the back side of a reinforcement carrier sheet, and a fabric at least partially embedded in the APP modified bitumen compound to provide a non-skid surface.

Abstract: A self-adhesive ventilating modified bituminous composite that comprises an unmodified bituminous or a polymer modified bituminous compound on the front side and a self-adhesive bituminous compound on the backside of a reinforcement carrier sheet is provided. A transfer lacquer printed release liner is applied to the tacky self-adhesive layer during manufacture. The transfer lacquer printed release liner is removed from the membrane just prior to use, such that the exposed surface of the membrane is placed directly onto the upper surface of the roof deck, base sheet or underlayment; force is applied directly to the sheet to enhance the adhesive bond between the tacky self-adhesive compound and the underlying substrate at approximately 50% of the area of contact in order to achieve a ‘partially-adhering’ membrane.

Abstract: A self-adhering modified bituminous roof covering composite that comprises a thermoplastic (APP), elastomeric (SBS) or TPO modified bitumen compound on the front side, and a factory-applied self-adhesive compound on the back side of a reinforcement carrier sheet, with factory-applied tracts of adhesive on the side lap and end lap sections of each roll to enhance adhesion.

Abstract: A self-adhering modified bituminous roofing tile underlayment material for tile roof assemblies that comprises an APP modified bitumen compound on the front side, and a factory-applied self-adhesive compound on the back side of a reinforcement carrier sheet, and granules embedded on the APP modified bitumen compound to provide a non-skid surface.

Abstract: A high strength polymeric composite laminate that has enhanced design features to perform as a roofing underlayment material for use in conjunction with modified bituminous materials such as APP or SBS membranes, as well as shingles, tiles, metal and other roof coverings.

Abstract: A self-adhering modified bituminous roof covering composite that comprises an APP modified bitumen compound on the front side, and a factory-applied self-adhesive compound on the back side of a reinforcement carrier sheet. A method of manufacturing such composite comprising coating an APP compound on the top surface and affixing a self-adhesive compound to the bottom surface of a reinforcement carrier support sheet, and applying a release liner to the tacky self-adhesive layer during manufacture, stripping the release liner, selvage release film and end lap film from the membrane immediately prior to use, subsequently placing the exposed surface of the membrane directly on to the upper surface of the roof deck, base sheet or underlayment, and applying force directly to the sheet to enhance the bond between the composite and the underlying surface that is created by the tacky self-adhesive compound. The present invention relates generally to residential and commercial roofing membranes and shingles.

Abstract: A reflective and emissive surface film laminate specially designed to form a top surface of modified bituminous roof covering composite such as membranes, underlayments and shingles to constitute a roof with thermal characteristics with substantially reduced amount of radiant energy entering a structure with such a covering.

Abstract: A modified bituminous roof covering composite such as membranes and underlayments that comprise a thermoplastic (atactic polypropylene), elastomeric (styrene-butadiene-styrene) or thermoplastic polyolefin (TPO) modified bituminous roofing material with a reflective and emissive surface laminate forming a top surface of the composite to constitute a roof with thermal characteristics which substantially reduced the amount of radiant energy entering a structure with such a covering.
