Abstract

Embodiments herein include extruded articles, building components and methods of making the same. In an embodiment, an extruded article is included. The extruded article can include a body member including a first portion comprising a first composition, the first composition comprising a polymer resin. The extruded body member can also include a second portion comprising a second composition different than the first composition. The second composition can include a polymer resin, fibers, and at least one component selected from the group consisting of at least 1% by weight particles and at least 5 phr impact modifier. Other embodiments are also included herein.

First claim

The invention claimed is:

1. An extruded article for a building component comprising:
a body member comprising
a wall surrounding at least one interior channel in cross-section, the wall comprising
a first extruded portion defining a first segment of a perimeter of the at least one interior channel, the first extruded portion comprising a first composition, the first composition comprising:
a polymer resin; and
at least 20 wt. % wood particles;

a second extruded portion defining a second segment of the perimeter of the at least one interior channel, the second extruded portion contacting the first extruded portion, the second extruded portion comprising a second composition different than the first composition, the second composition comprising:
a polymer resin; and
from 20 to 50 wt. % glass fibers;

a third extruded portion comprising a third composition, the third composition different than the first composition and the second composition.

2. The extruded article of claim 1 , the third extruded portion disposed over the first and second extruded portions as a capstock layer.

3. The extruded article of claim 1 , the second composition comprising at least 8 phr impact modifier.

4. The extruded article of claim 1 , wherein the first composition comprises less than 5 phr impact modifier.

5. The extruded article of claim 1 , the glass fibers having an average length after extrusion of 0.2 mm to 10 mm and an average diameter of about 2 microns to about 50 microns.

6. The extruded article of claim 1 , the first extruded portion further comprising a first lateral wall.

7. The extruded article of claim 1 , the second portion disposed within a wall, the second portion exhibiting thermal properties different than other portions of the wall such that it serves as a thermal break in the wall.

8. The extruded article of claim 1 , the body member comprising
an outer radius curved wall; and
an inner radius curved wall;
wherein the second extruded portion forms at least part of the outer radius curved wall.

9. The extruded article of claim 8 , the outer radius curved wall having a radius of curvature of 6 inches to 72 inches.

10. The extruded article of claim 1 , wherein the second portion further defines a fastener port.

11. The extruded article of claim 10 , the fastener port comprising two opposed walls.

12. The extruded article of claim 1 , the second portion further defining a flange.

13. The extruded article of claim 12 , the flange comprising a nailing flange.

14. An extruded article for a building component comprising:
a body member comprising
a wall surrounding at least one interior channel in cross-section, the wall comprising
a first extruded portion defining a first segment of a perimeter of the at least one interior channel, the first extruded portion comprising a first composition, the first composition comprising:
a polymer resin; and
at least 20 wt. % wood particles;

a second extruded portion defining a second segment of the perimeter of the at least one interior channel, the second extruded portion contacting the first extruded portion, the second extruded portion comprising a second composition different than the first composition, the second composition comprising:
a polymer resin; and

from 20 to 50 wt. % glass fibers;
wherein at least one of the first extruded portion and the second extruded portion within the wall exhibit thermal properties different than other portions of the wall such that it serves as a thermal break in the wall.

15. An extruded article for a building component comprising:
a body member comprising
a first extruded portion defining a first segment of a perimeter of the at least one interior channel, the first extruded portion comprising a first composition, the first composition comprising:
a polymer resin; and
at least 20 wt. % wood particles;

a second extruded portion defining a second segment of the perimeter of the at least one interior channel, the second extruded portion contacting the first extruded portion, the second extruded portion comprising a second composition different than the first composition, the second composition comprising:
a polymer resin; and

from 20 to 50 wt. % glass fibers;
the body member comprising
an outer radius curved wall; and
an inner radius curved wall;

wherein one of the first and second extruded portions forms at least part of the outer radius curved wall and the other of the first and second extruded portions forms at least part of the inner radius curved wall.

16. An extruded article for a building component comprising:
a body member comprising
a wall surrounding at least one interior channel in cross-section, the wall comprising
a first extruded portion defining a first segment of a perimeter of the at least one interior channel, the first extruded portion comprising a first composition, the first composition comprising:
a polymer resin; and
at least 20 wt. % wood particles;

a second extruded portion defining a second segment of the perimeter of the at least one interior channel, the second extruded portion contacting the first extruded portion, the second extruded portion comprising a second composition different than the first composition, the second composition comprising:
a polymer resin; and
from 20 to 50 wt. % glass fibers;

the second extruded portion defining at least one of a fastener port and a nailing flange.
