Thermoplastic flashing laminate
View Patent ↗A flashing laminate includes a non-reinforced thermoplastic sheet having a bottom surface, a first longitudinal edge, and a second longitudinal edge. The flashing laminate also includes an adhesive layer on a longitudinally extending portion of the bottom surface adjacent to one of the longitudinal edges. In one or more embodiments, the laminate also includes a release liner positioned over the adhesive tape.
1. A method of installing flashing laminate between a thermoplastic roofing membrane and a non-heat-weldable surface of a roof, the method comprising:
providing a flashing laminate including
(i) a non-reinforced thermoplastic sheet with a bottom surface, a first longitudinal edge and a second longitudinal edge,
(ii) an adhesive tape adhered to a longitudinally extending portion of said bottom surface of said sheet adjacent said second longitudinal edge, and
(iii) a release liner positioned over said adhesive tape opposite said sheet;
wherein said adhesive tape is adhered to only a portion of said bottom surface of said sheet, leaving the remaining portion of said bottom surface of said sheet exposed;
heat welding said exposed portion of said bottom surface of said thermoplastic sheet to the thermoplastic roofing membrane along said first longitudinal edge;
applying a primer to the non-heat-weldable surface and allowing the primer to dry;
removing said release liner from said adhesive tape; and
contacting said adhesive tape to said non-heat-weldable surface.
2. The method of claim 1 , where non-heat-weldable surface extends along an edge of the roof.
3. The method of claim 2 , where the non-heat-weldable surface is an edge metal flashing.
4. The method of claim 1 , wherein a portion of the adhesive tape extends beyond said second longitudinal edge.
