A membrane composite comprising a membrane panel having opposed first and second planar surfaces and a fabric backing secured to a first planar surface through a UV-cured adhesive disposed on said planar surface of said membrane.

Fabric-backed roofing membrane composite

A method of reroofing, the method comprising of applying to an existing roof surface a membrane composite including a pre-applied adhesive layer by mating the adhesive layer to the existing membrane.

Method of reroofing

A roof system comprising a roof substrate, a first membrane including first and second opposed planar surfaces, and a second membrane including opposed first and second planar surfaces, where said second membrane is adhered to said roof substrate through an adhesive disposed on said roof-substrate contacting portion of the first membrane, and where said second membrane is adhered to said first membrane through said adhesive disposed on a lap portion of said second membrane.

Fully-adhered roof system adhered and seamed with a common adhesive

An apparatus and related methods for constructing articles with cured pressure-sensitive adhesives comprising (i) a coater that applies a curable adhesive to a membrane; (ii) a cross-linking apparatus adapted to receive said membrane with said curable adhesive, said cross-linking apparatus comprising a light source positioned a first predetermined height above an aperture plate having an aperture therethrough, wherein said aperture plate is positioned a second predetermined height, said first predetermined height and said second predetermined height selected to define an exposure area of light emitted from said light source on to said curable adhesive to form a composite product; and (iii) a roll adapted to receive said composite product, said roll adapted to control a speed at which said membrane with said curable adhesive is exposed to light from said light source.

Process for preparing construction articles with cured pressure-sensitive adhesives

A roof system comprising a substrate and thermoplastic membrane adhered to the substrate, where the thermoplastic membrane is characterized, prior to being adhered to the substrate, by a stiffness represented by a flexural modulus of less than 90 MPa, or by a Taber stiffness of less than 15, or by a Shore D hardness of less than 40, or by a combination of a flexural modulus of less than 90 MPa, a Taber stiffness of less than 15, and a Shore D hardness of less than 40.

Thermoplastic roofing membranes for fully-adhered roofing systems

A method of installing a roofing membrane includes providing a membrane including a polymeric body having first and second opposed planar surfaces and a lap edge, a pressure-sensitive adhesive layer disposed on the first planar surface, and a release member removably affixed to the adhesive layer. Then, cutting the release liner while simultaneously scoring the adhesive layer along a line substantially parallel to the lap edge by use of a cutting and scoring tool and said step of cutting and scoring includes contacting the tool to the release liner. Finally, removing the release liner to expose the adhesive layer in the lap area; then applying a high-tensile member to the exposed adhesive layer in the lap area and forcibly removing the high-tensile member to thereby remove the adhesive layer within the lap area; and seaming the membrane composite to an adjacent membrane.

Roofing composite scoring tool and methods of use

A membrane composite comprising a polymeric membrane panel, an adhesive layer, and a release liner, where the adhesive layer is a pressure-sensitive adhesive that is at least partially cured, and includes at least two distinct regions with the at least two regions having distinct states of cure.

Roofing membranes with pre-applied, cured, pressure-sensitive seam adhesives

A walkway pad is provided for placement on a flat roof to protect the roof from foot traffic, tools, and/or equipment. The walkway pad includes a body and at least one expansion joint that absorbs thermal movement of the body. A method of manufacturing the walkway pad is also provided.
