Abstract

The present disclosure is directed to a soffit assembly made of inside and outside soffit boards, each comprising two or more serially arranged boards. When assembled, the inside and outside soffit boards define a central gap closed by a vent strip having perforations there along to enable breathing through said vent strip; the vent strip also icludes left and right U-shaped receptacles to enable the vent strip to snap to the adjacent soffit boards. A cross strip is also set forth which has a H-shape in profile to enable the adjacent boards to be abutted against each other and thereby joined with said cross strip at the joint between the boards.

Claims

1. A soffit assembly under an eave of a roof overhang on a building comprising:

(a) an elongate inside soffit board formed of two or more boards serially affixed along an outside wall of the building;

(b) an outside soffit board parallel to the inside soffit board and comprised of two or more boards parallel to and spaced from the inside board;

(c) wherein said inside and outside soffit boards define a gap therebetween having a specified length corresponding to the length of the outside wall; and

(d) a vent strip extending the full length of said inside and outside soffit boards wherein said vent strip

(i) has board engaging means along parallel edges of said vent strip enabling engagement with said inside and outside soffit boards,

(ii) enables air circulation therethrough into a space above said vent strip, and

(iii) is temporarily bowed for engagement with said inside and outside soffit boards.

2. The apparatus of claim 1 wherein said vent strip is constructed with a board engaging means comprising an edge located U-shaped receptacle.

3. The apparatus of claim 2 wherein said U-shaped receptacle has a length equal to that of said vent strip.

4. The apparatus of claim 3 wherein each of said parallel edges supports receptacles therealong to enable releasable engagement with said inside and outside soffit boards.

5. The apparatus of claim 4 wherein said vent strip has a uniform cross-sectional profile along the length thereof and is formed of an extruded vinyl material.

6. The apparatus of claim 4 wherein said vent strip has symmetrical left and right receptacles therealong said parallel edges and said receptacles have U-shaped openings therein to releasably engage the edges of said inside and outside soffit boards.

7. The apparatus of claim 1 wherein said inside soffit board is formed of two or more joints which form a butt joint and said butt joint supports an H-shaped cross strip having left and right receptacles therein engaging the boards of said inside soffit board.

8. The apparatus of claim 7 wherein said outside soffit board is formed of two or more joints which form a butt joint and said butt joint supports an H-shaped cross strip having left and right receptacles therein engaging the boards of said outside soffit board.

9. The apparatus of claim 8 wherein said cross strip has receptacles having a thickness sized to accommodate the thickness of boards comprising said inside soffit board.

10. The apparatus of claim 9 wherein said cross strip has receptacles having a thickness sized to accommodate the thickness of boards comprising said outside soffit board.

11. A soffit assembly under an eave of a roof overhang on a building comprising:

(a) an elongate inside soffit board formed of two or more boards serially affixed along an outside wall of the building;

(b) an outside soffit board parallel to the inside soffit board and comprised of two or more boards parallel to and spaced from the inside board;

(c) wherein said inside and outside soffit boards define a gap therebetween having a length up to the length of the outside wall and a continuous vent strip is located between said inside and outside soffit boards wherein said vent strip

(i) enables air circulation therethrough into a space above said vent strip,

(ii) has board engaging means along parallel edges of said vent strip enabling engagement with said inside and outside soffit boards, and is cut to the gap length, and

(iii) is temporarily bowed for engagement with said inside and outside soffit boards; and

(d) a cross strip positively engaging first and second boards comprising said inside soffit board.

12. The apparatus of claim 11 wherein said board engaging means of said vent strip is constructed with an edge located U-shaped receptacle for positioning said vent strip.

13. The apparatus of claim 12 wherein said U-shaped receptacle has a length equal to that of said vent strip.

14. The apparatus of claim 13 wherein each of said edges supports receptacles therealong to enable releasable engagement with said inside and outside soffit boards.

15. The apparatus of claim 14 wherein said vent strip has a uniform cross-sectional profile along the length thereof and is formed of an extruded vinyl material.

16. The apparatus of claim 14 wherein said vent strip has symmetrical left and right receptacles therealong said parallel edges and said receptacles have U-shaped openings therein to releasably engage the edges of said inside and outside soffit boards.

17. The apparatus of claim 11 wherein said inside soffit board is formed of two or more joints which form a butt joint and said butt joint is engaged with a H-shaped cross strip having left and right receptacles therein engaging the boards of said inside soffit board.

18. The apparatus of claim 12 wherein said outside soffit board is formed of two or more joints which form a butt joint and said butt joint supports an H-shaped cross strip having left and right receptacles therein engaging the boards of said outside soffit board.

19. The apparatus of claim 18 wherein said cross strip has receptacles having a thickness sized to accommodate the thickness of boards comprising said inside soffit board.

20. The apparatus of claim 19 wherein said cross strip has receptacles having a thickness sized to accommodate the thickness of boards comprising said outside soffit board.

21. A method of constructing a soffit to provide ventilation through the soffit into the attic space thereabove wherein the soffit is constructed beneath an overhanging eave and comprises the steps of:

(a) placing a soffit board under an eave extending along a vertical wall, wherein the soffit board has a first exposed edge;

(b) positioning a second soffit board parallel to the first board wherein said first and second boards define a space therebetween at the edges of said boards;

(c) closing the space between the first and second boards with a perforated sheet defining, in the aggregate, an air flow space through perforations in said sheet into the attic area above said first and second boards; and

(d) wherein said sheet incorporates first and second board edge engaging channels overlapping said first and second boards to hold said sheet in place and to cover the edges of said boards and said sheet is cut to length to cover the length of said space.

22. The method of claim 21 wherein said step of defining the edges of said sheet with U-shaped board engaging receptacles.

23. The method of claim 21 wherein said receptacles have a throat with depth sufficient to grasp the edges of said first and second boards.

24. The method of claim 21 wherein the boards are cut by a saw to define said board edges and said board edges are irregular dependent on the saw cutting operation, and wherein said receptacles have a defined width sufficient to cover the saw cut edges.
