Abstract

The present application is generally directed to multifunctional flashing devices suitable for installation of lap siding. Flashing devices include a flashing section, a removable supporting section, and one or more alignment features configured to facilitate positioning of the flashing devices adjacent to an installed course of lap siding. The flashing devices may be fastened to a building substrate adjacent to an installed course of lap siding, at locations corresponding to butt joints of an additional course of lap siding. The supporting sections of the flashing devices are configured to retain and support additional cladding elements in position for installation. When the additional cladding elements have been fastened to the building substrate, the supporting section may be removed from the flashing section.

First claim

What is claimed is:

1. An integrally formed multifunctional flashing device comprising:
a flashing section comprising:
a substantially planar portion having a first end and a second end opposite the first end; and
a cladding engagement surface extending from the second end of the substantially planar portion, the cladding engagement surface having a first end adjacent to the second end of the substantially planar portion and a second end opposite the first end of the cladding engagement surface; and

a supporting section comprising:
a first side member extending from the second end of the cladding engagement surface away from the substantially planar portion, the first side member having a first end adjacent to the second end of the cladding engagement surface and a second end opposite the first end of the first side member;
a base member extending from the second end of the first side member away from the cladding engagement surface; and
a second side member extending from an end of the base member opposite the first side member such that the first side member, the base member, and the second side member define a u-shaped channel sized and shaped to receive a cladding element therein;

the first side member including a breakaway section spaced apart from the second end of the first side member, the breakaway section comprising a locally thin or perforated region of the first side member disposed between the cladding engagement surface and the base member.

2. The integrally formed multifunctional flashing device of claim 1 , wherein the integrally formed multifunctional flashing device comprises 24-ga sheet aluminum.

3. The integrally formed multifunctional flashing device of claim 1 , wherein the integrally formed multifunctional flashing device comprises a polymeric material having a thickness of approximately 0.1 cm (approximately 0.04 inches).

4. The integrally formed multifunctional flashing device of claim 1 , wherein the breakaway section comprises two opposing notches having a depth of approximately 0.025 cm (approximately 0.01 inches).

5. The integrally formed multifunctional flashing device of claim 1 , wherein the integrally formed multifunctional flashing device comprises extruded polyvinyl chloride (PVC).

6. The integrally formed multifunctional flashing device of claim 1 , wherein the integrally formed multifunctional flashing device comprises extruded polyvinyl chloride (PVC) including an ultraviolet (UV) inhibitor.

7. The integrally formed multifunctional flashing device of claim 1 , wherein the breakaway section is spaced between approximately 0.45 cm and approximately 0.5 cm (between approximately 0.18 inches and approximately 0.24 inches) from the second end of the first side member.

8. The integrally formed multifunctional flashing device of claim 1 , wherein the cladding engagement surface is disposed at an angle of between 100° and 110° relative to the substantially planar portion.

9. The integrally formed multifunctional flashing device of claim 1 , wherein the second side member is disposed at an angle of between 100° and 110° relative to the base member.

10. The integrally formed multifunctional flashing device of claim 1 , further comprising one or more flashing fastening apertures extending through the substantially planar portion.

11. A cladding system comprising:
a first course of lap siding comprising at least a first cladding element affixed to a building substrate by a plurality of first mechanical fasteners;
the integrally formed multifunctional flashing device of claim 6 affixed to the building substrate by at least one second mechanical fastener such that the cladding engagement surface lies adjacent to an upper edge of the first cladding element and the first side member lies adjacent to an exterior face of the first cladding element; and
a second course of lap siding comprising a second cladding element and a third cladding element, the second cladding element and the third cladding element affixed to the building substrate by a plurality of third mechanical fasteners, the second cladding element and the third cladding element each being partially disposed within the u-shaped channel to form a cladding joint between the second cladding element and the third cladding element.

12. A cladding system comprising:
a first course of lap siding comprising at least a first cladding element affixed to a building substrate by a plurality of first mechanical fasteners;
a multifunctional flashing device affixed to the building substrate by at least one second mechanical fastener, the multifunctional flashing device comprising:
a substantially planar portion parallel to the first cladding element, the substantially planar portion having a top end and a bottom end opposite the top end, the at least one second mechanical fastener passing through the substantially planar portion;
a cladding engagement surface extending in an exterior direction from the bottom end of the substantially planar portion such that the cladding engagement surface lies adjacent to an upper edge of the first cladding element, the cladding engagement surface having an interior end adjacent to the bottom end of the substantially planar portion and an exterior end opposite the first end;
a first side member extending in a downward direction from the exterior end of the cladding engagement surface parallel to the substantially planar portion such that the first side member lies adjacent to an exterior face of the first cladding element; and
a u-shaped channel defined by the first side member, a base member extending from a bottom end of the first side member, and a second side member extending upward from an exterior end of the base member; and

a second course of lap siding comprising a second cladding element and a third cladding element, the second cladding element and the third cladding element affixed to the building substrate by a plurality of third mechanical fasteners, the second cladding element and the third cladding element each being partially disposed within the u-shaped channel to form a cladding joint between the second cladding element and the third cladding element;
wherein the first side member further includes a breakaway section comprising one or more notches or grooves located therein, the breakaway section disposed between the cladding engagement surface and the base member, the multifunctional flashing device configured to be separated along the breakaway section to form a permanent flashing for the cladding joint.

13. The cladding system of claim 12 , wherein the one or more notches or grooves have a depth of approximately 0.025 cm (approximately 0.01 inches).

14. The cladding system of claim 12 , wherein the multifunctional flashing device comprises formed 24-ga sheet aluminum or a polymeric material.

15. The cladding system of claim 12 , wherein the multifunctional flashing device comprises extruded polyvinyl chloride (PVC) including an ultraviolet (UV) inhibitor.

16. A cladding system comprising:
a first course of lap siding comprising at least a first cladding element affixed to a building substrate by a plurality of first mechanical fasteners;
a multifunctional flashing device affixed to the building substrate by at least one second mechanical fastener, the multifunctional flashing device comprising:
a substantially planar portion parallel to the first cladding element, the substantially planar portion having a top end and a bottom end opposite the top end, the at least one second mechanical fastener passing through the substantially planar portion;
a cladding e
