20100173110 | Skid Resistant Membrane - Described is a skid-resistant roofing underlayment that, in its most basic form, includes three layers—a flexible substrate layer, an adhesive layer and a release liner layer. The flexible substrate comprises a woven polyolefin mesh that includes a first plurality of polyolefin tapes extending in a major direction interwoven with a second plurality of polyolefin tapes extending in a cross direction. The adhesive layer includes a modified bitumen pressure sensitive adhesive with a sufficient cohesive strength to prevent exudation of the adhesive through the flexible substrate at elevated temperatures. | 07-08-2010 |
20100196647 | SHINGLE SEALANT AND ADHESIVE - Disclosed roofing shingles and related methods of manufacturing provide a reinforced material that strengthens the bond between shingles by reducing the affect of heat on the sealant/adhesive between shingles in one or more areas where sealant/adhesive is applied or where it contacts other shingles once installed on a roof deck. The reinforcement material acts as fiber reinforcement to the sealant/adhesive. The reinforcement material intertwines with the sealant/adhesive, and thereby helps the shingles resist delaminating or slipping or blow-off when subjected to high heat conditions or on very steep sloped roofs. The reinforcement material helps retain the strength of the adhesive bond between shingles in these conditions by providing fiber reinforcement to the adhesive bond. Thus, as the adhesive turns from a solid state to a more liquefied state in hot temperatures, the totality of the reinforcement material does not so transform, and thus retains more strength in the adhesive bond between the two shingles than mere adhesive/sealant alone. | 08-05-2010 |
20100196648 | Waterproofing Membrane - Disclosed is a waterproofing membrane that performs well at both high and low temperatures. The waterproofing membrane comprises a carrier support layer and an adhesive layer, wherein the adhesive layer comprises a pressure sensitive bitumen composition comprising bitumen (asphalt), synthetic rubber, high density polyethylene, ground vulcanized crumb rubber and, optionally, a plasticizer. The waterproofing membrane also may optionally include a removable release sheet on the adhesive layer. | 08-05-2010 |
20100233408 | WEATHERPROOF UNDERLAYMENT WITH HIGH FILLER CONTENT POLYMER ASPHALT LAYER - A roofing membrane underlayment material includes a fibrous mat generally encapsulated within a non-adhesive asphalt coating, the resulting encapsulated mat having an adhesive asphalt layer applied to one surface thereof, typically the bottom surface. An acrylic, talc or granular coating is applied to the surface of the encapsulated mat that is not in contact with the adhesive asphalt layer. The non-adhesive asphalt coating is characterized in that it includes a high filler content made possible by the use of non-oxidized flux asphalt to which has been added a small percentage of an asphalt additive such as radial or linear polymer or other elastomer. 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 and is flexible in both hot and cold environments. | 09-16-2010 |
20110052852 | Waterproofing Membrane - Disclosed is a waterproofing membrane that performs well at both high and low temperatures. The waterproofing membrane comprises a carrier support layer and an adhesive layer, wherein the adhesive layer comprises a pressure sensitive bitumen composition comprising bitumen (asphalt), synthetic rubber, high density polyethylene, amorphous polyolefin, ground vulcanized crumb rubber and, optionally, a plasticizer. The waterproofing membrane also may optionally include a removable release sheet on the adhesive layer. | 03-03-2011 |
20110091675 | FLASHING AND WATERPROOFING MEMBRANE - A laminate tape that has a bottom layer of aggressive adhesive formulated to have sufficient adhesion to construction materials to as low as 20 degrees F. The adhesive is applied in a layer of about 2 to 5 mils. A second layer that is about 10 to 60 mils thick is made of rubberized asphalt, which provides self-sealing capabilities. In one embodiment, the first layer has strips of adhesive and sections of rubberized asphalt. The third layer is a film, which can be a thin, contiguous polymer, fabric or particulate. The laminate can be used where a strong adhesive is needed that will adhere to construction materials at or near 20 degrees Fahrenheit, while still retaining self-sealing characteristics. | 04-21-2011 |
20130122232 | EXPANDABLE FLASHING MEMBRANE - Disclosed herein are various membranes that may be applied to an opening in a building structure to seal around and/or waterproof the opening. To provide improved conformance of the membrane to underlying surfaces the membrane utilizes a facer film that permits permanent stretching without the application of little or any elastic/retractive forces by the facer film. In one embodiment, the length of the facer film is in excess of the length of an adhesive substrate of the membrane to allow stretching of the substrate without stretching the facer film. In another embodiment, the facer film has low elastic memory such that it plastically detail is as the underlying adhesive substrate stretches. | 05-16-2013 |
20130243991 | INTERMEDIATE COMPOSITE PANEL FOR ROOFING AND WALLS - A composite intermediate panel comprises a structural layer providing the structural integrity of the composite intermediate panel. Pressure-sensitive adhesive layers are on opposite main surfaces of the structural panel, the pressure-sensitive adhesive layers applied in plant. A backing sheet layer is provided for each adhesive layer, the backing sheet layer adhered to the pressure-sensitive adhesive layer, and being peelable off the pressure-sensitive adhesive layer to expose the pressure-sensitive layer. Attachment units of rigid material are on one of the main surfaces of the building panel, the attachment units being positioned at a location where mechanical fasteners secure the building panel to a structure. | 09-19-2013 |
20130316113 | RELEASE FILM HAVING A ROUGH SURFACE STRUCTURE - Release film having at least one layer based on at least one thermoplastic polymer as matrix polymer, in which solid microparticles having a melting point which is at least 10° C. higher than that of the matrix polymer are dispersed therein and surfaces of which at least one is provided with a release layer as outer layer based on at least one cured polysiloxane. | 11-28-2013 |
