A composition including a melt blend of at least one thermoplastic elastomer (TPE) and at least one non-crosslinked elastomer and optionally at least one catalyst for catalyzing chain extension and/or crosslinking and/or coupling reactions of the at least one non-crosslinked elastomer. Further, a method for producing a polymer composition, to a shaped article including a substrate layer composed of the composition, to a method producing a shaped article, and to a method for covering a roof using the shaped articles.

A method of fixing a membrane to a surface is disclosed. The method includes affixing a metallic washer having a heat-activated adhesive layer on a surface; arranging a membrane on top of the surface and the heat-activated adhesive layer of the metallic washer; heating the metallic washer to activate the heat-activated adhesive layer such that the membrane is fixable to the metallic washer; positioning a magnetic clamping heat sink assembly on the membrane; magnetically clamping the magnetic clamping heat sink assembly to the metallic washer causing the magnetic clamping heat sink assembly to apply a force against the membrane when the magnetic clamping heat sink assembly sufficiently overlaps the metallic washer to form a secure bond; and cooling the metallic washer, the heat-activated adhesive layer, and the membrane by removing heat through the magnetic clamping heat sink assembly.

A roof assembly comprising: a roof deck; a thermoplastic membrane covering the deck; and a fabric having disposed thereon expandable graphite.

A roof assembly comprising: a roof deck; a thermoplastic membrane covering the deck; and a fabric having disposed thereon expandable graphite.

A dual strip protective edge film system for a roofing membrane having a first protective edge film strip covering a top edge portion of the roofing membrane and a second protective edge film strip covering a top portion of the roofing membrane, wherein the second protective edge film strip is positioned in parallel next to the first protective edge film strip, and wherein both of the edge strips have a combined width approximately equal to the width of the overlap between two overlapping roofing membranes that are adhesively secured or thermally welded together.

A roofing membrane composite includes a roofing membrane and a protective film removable affixed to a top major surface of the roofing membrane without an adhesive layer between the protective film and the roofing membrane, wherein the protective film includes at least one layer with at least one polyolefin. A method for producing a roofing membrane composite and a method for waterproofing a roof substrate.

An electric roofing torch comprising a tubular body having an upstream end and a downstream end, a fan unit mounted in the tubular body to drive a flow of air through the tubular body and a heater tube comprising a heater matrix, the heater tube being mounted in the tubular body to heat the flow of air as it passes through the tubular body. The fan unit comprises an electric vaneaxial fan which is mounted upstream of the heater tube. The fan unit is mounted in the tubular body to drive a flow of air through the tubular body at velocity, pressure and volume that is sufficient for roofing operations such as laying roofing membranes, with zero carbon emissions. There is also provided a method of providing a working flow of hot air from the electric roofing torch for such a roofing operation.

A thermochromic indicator and its use for visually determining whether adjacent surfaces of overlapping edge portions of side-by-side roofing membrane segments have been sufficiently heated to a preselected temperature threshold to achieve a desired weld therebetween to correspondingly seal the roofing membrane seam.

A membrane including a top waterproofing layer and optionally a layer of fiber material, wherein the top waterproofing layer includes at least one thermoplastic polymer P, at least one thermochromic pigment TP, and at least one UV-light absorber A. Such membranes are able to change their color as a response to a change in temperature, which enables controlling the amount of heat energy absorbed into the membrane and transmitted to a building structure. Further, a method for producing a membrane and to a method for covering a substrate using the membranes of the invention.

A thermal welding marking system for attachment to a thermal welding machine including: a hammer arm rotatably connected to a mounting bracket attached to the thermal welding machine, wherein a distal end of the hammer arm is shaped to receive a marker or pen therein; a cable or spring connected to the distal end of the hammer arm; a cable connecting the hammer arm to a hand lever mounted adjacent to hand controls on the thermal welding machine, wherein movement of the hand lever raises or lowers the distal end of the hammer arm and thereby raises or lowers the marker or pen therein. In operation, the thermal welding machine is advanced across the edges of overlapping building roofing material and the marker or pen is intermittently lowered/raised to mark locations along a seam of the edges of overlapping building roofing material where the seam is either open or closed.
