Abstract

A method for using a support backer board system and siding. The support backer board system comprises at least a first layer. The first layer is made from a material selected from the group consisting of alkenyl aromatic polymers, polyolefins, polyethylene terephthalate, polyesters, and combinations thereof. The board system is thermoformed into a desired shape with the desired shape being generally contour to the selected siding. The siding is attached to the board system so as to provide support thereto. In one process, the siding may be vinyl.

Claims

1. A method for using a support backer board system and siding, said support backer board system comprising at least a first layer, the method comprising the steps of:

providing siding;

extruding a first layer to form said board system, said first layer being made from a material selected from the group consisting of alkenyl aromatic polymers, polyolefins, polyethylene terephthalate, polyesters, and combinations thereof;

thermoforming said board system into a desired shape, said desired shape being generally contour to said sliding, said board system being adapted unfold at hinges therein; and

attaching said siding to said board system so as to provide support to said siding.

2. The method of claim 1, wherein said siding is made from vinyl or polymer materials.

3. The method of claim 1, wherein said thermoforming step is performed as an in-line process.

4. The method of claim 1, wherein said thermoforming step comprises placing the extrudated board system in a mold and forming the board system into the desired shape under pressure.

5. The method of claim 1, wherein said thermoforming step is performed as an off-line process.

6. The method of claim 5, wherein said thermoforming step comprises heating the extrudated board system, placing the heated extrudated board system in a mold, and forming the board system into the desired shape under pressure.

7. The method of claim 1, wherein the first layer is an alkenyl aromatic polymer.

8. The method of claim 7, wherein the alkenyl aromatic polymer is polystyrene.

9. The method of claim 1, wherein said board system further comprises a second layer, said second layer being made from a material selected from the group consisting of alkenyl aromatic polymers, polyolefins, polyethylene terephthalate, polyesters, and combinations thereof.

10. The method of claim 9, wherein said board system further comprises a third layer, said third layer being made from a material selected from the group consisting of alkenyl aromatic polymers, polyolefins, polyethylene terephthalate, polyesters, adhesives, and combinations thereof.

11. The method of claim 10, wherein said second and third layers are made of high impact polystyrene.

12. The method of claim 1, wherein said board system comprises a first layer, a second layer, a third layer, and a fourth layer, said first layer being comprised of a polystyrene, said second layer being comprised of a polystyrene or a polyolefin, said third layer being comprised of an adhesive, and said fourth layer being comprised of a polystyrene or a polyolefin.

13. The method of claim 1, wherein the step of attaching includes using nails, screws, staples, or a combination thereof.

14. The method of claim 1, wherein said board system has a thickness from about 125 to about 500 mils.

15. The method of claim 1, further comprising the steps of providing a material selected from plywood, orientated strand board, foamed sheathings, beadboard, hardboard, blackboard, fiberboard, and existing siding, and attaching said board system and said material.

16. A method for using a support backer board system and siding, said support backer board system comprising at least three layers, the method comprising the steps of:

providing siding;

extruding a first layer to form said board system, said first layer being made from at least one foamed alkenyl aromatic polymer;

adding a second layer and a third layer to said first layer so as to form said board system, said second layer and third layers being film layers made from independently selected resin;

said first layer being located in between the second layer and said third layer;

thermoforming said board system into a desired shape, said desired shape being generally contour to said siding; and

attaching said siding to said board system so as to provide support to said siding.

17. The method of claim 16, wherein said alkenyl aromatic polymer is polystyrene.

18. The method of claim 16, wherein said siding is made from vinyl or polymer materials.

19. The method of claim 16, wherein said thermoforming step comprises placing the extrudated board system in a mold and forming the board system into a desired shape under pressure.

20. The method of claim 16, wherein said board system is adapted to unfold at hinges therein.

21. The method of claim 16, wherein said second and third layers are made from materials selected from the group consisting of alkenyl aromatic polymers, polyolefins, polyethylene terephthalate, polyesters, adhesives, and combinations thereof.

22. The method of claim 21, wherein said second and third layers are made from high impact polystyrenes.

23. The method of claim 16, wherein said thermoforming step comprises placing the extrudated board system in a mold and forming the board system into a desired shape under pressure.

24. The method of claim 16, wherein said thermoforming step comprises heating the extrudated board system, placing the heated extrudated board system in a mold, and forming the board system into a desired shape under pressure.

25. The method of claim 16, wherein the step of attaching includes using nails, screws, staples, or a combination thereof.

26. The method of claim 16, wherein said board system has a thickness from about 125 to about 500 mils.

27. The method of claim 16, further comprising the steps of providing a material selected from plywood, orientated strand board, foamed sheathings, beadboard, hardboard, blackboard, fiberboard, and existing siding, and attaching said board system and said material.

28. The method of claim 16, wherein said board system is in the form of a sheet.
