Abstract

An improved butt jointed siding system.

First claim

What is claimed is:

1. A siding system comprising:
(a) composite a siding member comprising a thermoplastic polymer and glass fiber composite, the composite siding member composite having a COTE less than 2.0×10° in/in/° F.; and
(b) a tape adhered to the composite siding member comprising a tape film and an adhesive layer, the tape having a portion thereof adhered to the composite siding member and a remaining portion thereof having the adhesive layer covered by a release liner;
(i) the tape having a tensile modulus greater than about 50,000 psi and polymer memory;
(ii) the adhesive layer having a peel strength of greater than 5 lb./lineal inch and comprising at least 10 wt. % of a polymer with a Tg less than −10° C.; wherein the composite siding member comprises greater than 5 vol. % glass fiber and less than 95 vol. % polymer.

2. The siding system of claim 1 wherein the composite siding member has a COTE of less than 1×10° in/in/° F.

3. The siding system of claim 1 wherein the thermoplastic polymer comprises PVC and the glass fiber; wherein the glass fiber 1s coated with an interfacial modifier.

4. An environmentally stable siding system comprising:
(a) a composite siding member comprising a thermoplastic polymer, the composite siding member having a COTE less than 2×10° in/in/° F.; and
(b) adhered to the composite siding member is a tape comprising a tape film and an adhesive, the tape having a portion of the tape thereof adhered to the composite siding member and a remaining portion thereof having an adhesive layer covered by a release liner;
(i) the tape having a tensile modulus greater than about 50,000 psi and polymer memory;
(ii) the adhesive layer having a peel strength of greater than 5 lb./lineal inch and comprising at least 10 wt. % of a polymer with a Tg less than −10° C.; wherein the composite siding member comprises greater than 5 vol. % glass fiber and less than 95 vol. % polymer.

5. The environmentally stable siding system of claim 4 further comprising a reinforcing fiber mixed with the thermoplastic polymer to form a composite.

6. The environmentally stable siding system of claim 5 wherein the composite siding member has a COTE of less than 1×10° in/in/° F.

7. The environmentally stable siding system of claim 5 , wherein the thermoplastic polymer comprises PVC and the glass fiber; wherein the glass fiber is coated with an interfacial modifier.

8. A siding comprising:
at least a first siding member and a second siding member in a butt joint relationship;
the first and second siding members installed on a vertical rough construction surface;
the first and second siding members comprising a thermoplastic polymer and a glass fiber composite, the first and second siding member each having a COTE less than 2×10 −5 in/in/° F.;
adhered to a reverse side of each of the first and second siding members spanning the butt joint, a tape having an adhesive layer between a tape film and the first and second siding members;
wherein the tape has a tensile modulus greater than about 0.8 GPa and polymer memory; the adhesive layer has a peel strength of greater than 5 lb./lineal inch and comprising at least a 10 wt. % of a polymer with a Tg less than less than −10° C.; and wherein the composite of the first and second siding members comprises greater than about 5 vol. % glass fiber and less than about 95 vol. % of polymer.

9. The siding of claim 8 further comprising a space of less than 0.5 mm between the first siding member and the second siding member.

10. The siding of claim 8 further comprising the glass fiber; wherein the glass fiber has a coating of an interfacial modifier.

11. The siding of claim 10 further comprising an organometallic interfacial modifier.

12. The siding of claim 8 wherein there is no gap at the butt joint.

13. The siding of claim 11 wherein the first and second siding members have a COTE of less than 1×10 −6 in/in/° F.

14. The siding of claim 12 wherein a fish mouth is not formed at the butt joint when subjected to an environmental stress.

15. The siding of claim 11 wherein the thermoplastic polymer comprises PVC.
