Abstract

A reinforced tape strip for securing a membrane roof to a roof deck or a parapet wall of a roof deck. The reinforced tape strip includes a layer of a single ply reinforcement material, at least one adhesive layer of a uniform thickness bonded to the single ply reinforcement material, and a protective layer covering the adhesive layer.

Claims

1. A reinforced tape strip composite for securing a membrane roof to a roof deck or a parapet wall of a roof deck, the reinforced tape strip composite consisting essentially of:

a reinforcement layer consisting essentially of a single ply fabric reinforcement material;

at least one adhesive layer of a uniform thickness prebonded to said single ply fabric reinforcement material before the reinforced tape strip is fastened to the roof deck or the parapet wall, said at least one adhesive layer capable of being adhered to the membrane roof; and

a protective layer covering said adhesive layer.

2. The reinforced tape strip of claim 1 wherein said single ply reinforcement material is selected from the group consisting of polyester, nylon, polypropylene and fiberglass.

3. The reinforced tape strip of claim 1 wherein said adhesive layer is selected from the group consisting of EPDM based polymer adhesive, butyl based polymer adhesive or a blend thereof.

4. The reinforced tape strip of claim 3 wherein said adhesive layer is of a thickness from 0.015 inches to 0.060 inches.

5. The reinforced tape strip of claim 3 wherein said adhesive layer is approximately 0.030 inches thick.

6. The reinforced tape strip of claim 3 wherein said reinforcement layer is of a woven fabric material.

7. The reinforced tape strip of claim 3 wherein said reinforcement layer is of a non-woven fabric material.

8. The reinforced tape strip of claim 3 wherein said reinforcement layer is of a composite formed of a non-woven fabric material and a woven fabric material.

9. The reinforced tape strip of claim 3 wherein said reinforcement layer has thickness ranging from about 0.006 to 0.026 inches.

10. The reinforced tape strip of claim 6 wherein said reinforcement layer is a woven fabric material having a thread count ranging from approximately 5-30 threads per inch and a thread thickness between 100 and 3000 denure.

11. The reinforced tape strip of claim 6 wherein said reinforcement layer is a woven polyester material having a thread thickness of 1000 denure and having a thread count of 10 threads per inch.

12. The reinforced tape strip of claim 10 wherein said reinforcement layer is positioned between two layers of adhesive.

13. The reinforced tape strip of claim 10 wherein said protective layer includes a release liner, said release liner comprising a release paper faced with polyethylene and having a silicone release coating.

14. The reinforced tape strip of claim 10 wherein said protective layer includes a release liner, said release liner comprising a release paper faced with polypropylene and having a silicone release coating.

15. The reinforced tape strip of claim 13 wherein said release liner comprises a release paper having a thickness ranging from about 0.004 to about 0.011 inches.

16. The reinforced tape strip of claim 13 wherein said release paper is about 0.007 inches thick.
