A separation sheet includes a polymeric carrier layer, a first adhesive layer, a second adhesive layer, and optionally a first and a second release liner. A method for producing a separation sheet, a method for waterproofing a substrate, a waterproofed substrate, and a use of the separation sheet for bonding of roof membranes to roof substrates.

A system includes a plurality of roofing modules and a plurality of photovoltaic modules. The roofing modules include a first layer and a second layer. The first layer has a first surface that is textured. The roofing modules are configured to be installed on the roof deck of a structure proximate to the photovoltaic modules. An appearance of the roofing modules aesthetically matches an appearance of the photovoltaic modules when viewed from a vantage point located at a ground level of the structure.

A membrane roofing system that includes a waterproof layer that protects an insulation layer and a granule coupled to the waterproof layer. The granule has a 60% or greater reflectivity that reduces transmission of ultraviolet light to the waterproof layer. The granule is coated in a fluorinated acrylic copolymer that resists adsorption and absorption of asphaltic chemicals by the granule from the waterproof layer.

Systems and methods are described herein for manufacturing and using roofing membranes that are faster and easier to install than conventional adhesive-only membrane materials. In some embodiments, membrane materials are surface treated using a plasma flow, e.g., a blown-arc plasma flow, atmospheric plasma, corona plasma, or from portable plasma units, generated by passing a compressed plasma-generating gas through an electrical current to form the plasma-treated roofing membrane. The plasma treatments described herein may be applied as part of the manufacturing process, or in-situ at the site of roof installation. In some embodiments, membrane materials have surface chemistries, roughnesses and other surface characteristics that yield desired adhesion properties.

A method for producing an asphaltic sheet, the method comprising of providing an asphaltic sheet; and applying expandable graphite particles to the asphaltic sheet.

According to one embodiment, a halogen free roof system is described. The roof system includes a structural deck that is positioned above joists or other support members. Polyisocyanurate foam insulation is positioned atop the structural deck. The polyisocyanurate foam insulation has an isocyanate index greater than 200 and includes a polyisocyanurate core having a halogen free fire retardant. A water proof membrane is positioned atop the polyisocyanurate foam insulation. The polyisocyanurate core is able to form a sufficiently stable char when exposed to flame conditions such that the polyisocyanurate core is able to pass the ASTM E-84 test.

A process for in-line extrusion of polymeric coatings onto roofing shingles during manufacturing includes moving a web of shingle substrate material in a downstream direction and extruding a liquefied coating of polymeric material onto at least one surface of the moving web to form a thin film. The liquefied coating may be a molten polymeric material that forms a thin film on a back surface of the shingle material to prevent sticking and eliminate the need for a traditional back dusting with material such as powdered stone. The polymeric film further may be applied to the substrate material in lieu of a saturation coating of asphalt, thus reducing cost and weight while providing a comparable moisture barrier and a lighter more flexible shingle.

The present invention relates generally to an improved below grade, blind side, dual waterproofing membrane assembly incorporating a sheet membrane with adhesive to fully bond to concrete/shotcrete, and a method of making and using same. More particularly, the invention encompasses a dual membrane system that acts as a barrier, and prevents, and blocks water and moisture, from passing from one side of the structure to the other side. The innovative barrier layer system can be used along a wall, a floor, a ceiling, or along any structure which requires water or moisture proofing. The invention can be most effectively used between a concrete or shotcrete layer and the surrounding earth, such as, along an area that has a high water table or ground moisture or hydrostatic pressure that may creep into a foundation or a wall. The inventive system comprises two different waterproofing layers, and materials.

A house sealing method is herein provided. The method involves using a tacky on both sides detail membrane having a reinforced inner core to seal various areas of a building envelope.

The invention includes a microbe-mitigating architectural barrier that includes a barrier forming material, and at least one biocide. The barrier forming material may be a bitumen product, an elastomeric polymer and combinations thereof. The microbe-mitigating architectural barrier may be formed by applying an emulsion composition directly to an architectural surface, or may be pre-formed and adhered or otherwise secured to the architectural surface in the form of a sheet or film. The invention also includes architectural assemblies and/or building envelopes that include the microbe-mitigating barrier. Related methods encompassed within the invention include a method of preparing an architectural barrier that includes: (a) preparing an emulsion that comprises a barrier forming material chosen from a bitumen product, an elastomeric polymer and combinations thereof, and at least one biocide, (b) applying the emulsion to at least one architectural surface, and (c) drying and/and or curing the emulsion to form a barrier.
