Abstract

Insulated buildings are described. The building include: (a) a sloped roof that is a prefabricated insulated roof assembly; (b) a generally horizontally arranged flooring assembly having an end that is arranged over a wall structure and under the sloped roof assembly; (c) a sloped member that is arranged over the end of the flooring assembly that is over the wall structure, and (d) a rigid foam insulation member arranged in the cavity of the roof assembly so as to bridge a lower surface of a rigid foam insulation board in the roof assembly to the sloped member.

First claim

What is claimed is:

1. A building comprising:
(a) a sloped roof comprising an insulated roof assembly;
(b) a generally horizontally arranged flooring assembly comprising an end thereof that is arranged over a wall structure and under the sloped roof assembly;
(c) a sloped member that is arranged over the end of the flooring assembly that is over the wall structure, and
(d) a rigid foam insulation member arranged in a cavity of the roof assembly so as to bridge a lower surface of a rigid foam insulation board in the roof assembly to the sloped member,
wherein the insulated roof assembly comprises:
(1) a sheathing panel comprising an upper surface and a lower surface;
(2) a plurality of I-joists positioned in a generally parallel relationship to each other, the I-joists comprising:
(i) an upper flange,
(ii) a lower flange, and
(iii) a web extending between the upper flange and the lower flange,

wherein the lower surface of the sheathing panel faces an upper surface of the upper flange of the I-joists so that the sheathing panel and the I-joists define the cavity;
(3) a generally planar first rigid foam insulation board comprising:
(i) an upper surface,
(ii) a lower surface,
(iii) a first side, and
(iv) a second side that is opposite of the first side,

wherein the first rigid foam insulation board is positioned in the cavity such that:
(i) the upper surface of the first side of the first rigid foam insulation board faces the lower surface of the upper flange of a first I-joist,
(ii) the upper surface of the second side of the first rigid foam insulation board faces the lower surface of the upper flange of a second I-joist,
(iii) an edge of the first side of the first rigid foam insulation board faces the web of the first I-joist, and
(vi) an edge of the second side of the first rigid foam insulation board faces the web of the second I-joist.

2. The building of claim 1 , wherein the insulated roof assembly comprises a generally planar second rigid foam insulation board comprising:
(i) an upper surface,
(ii) a lower surface,
(iii) a first side, and
(iv) a second side that is opposite of the first side,
wherein the second rigid foam insulation board is positioned in the cavity such that:
(i) the upper surface of the second rigid foam insulation board faces the lower surface of the first rigid foam insulation board,
(ii) the lower surface of the second rigid foam insulation board faces the upper surface of the lower flange of a first I-joist in a spaced-apart relationship at the first side of the second rigid foam insulation board,
(iii) the lower surface of the second rigid foam insulation board faces the upper surface of the lower flange of a second I-joist in a spaced-apart relationship at the second side of the second rigid foam insulation board,
(iv) an outer edge of the first side of the second rigid foam insulation board faces the web of the first I-joist, and
(v) an outer edge of the second side of the second rigid foam insulation board faces the web of the second I-joist.

3. The building of claim 1 , wherein the first rigid foam insulation board and the rigid foam insulation member each comprise a polyisocyanurate foam board, an expanded polystyrene foam board, or an extruded polystyrene foam board.

4. The building of claim 2 , wherein the first rigid foam insulation board and the second rigid foam insulation board each comprise a facer material on an upper face and/or a lower face of a foam layer.

5. The building of claim 4 , wherein the first rigid foam insulation board has a thickness of 2½ to 4 inches and comprises a polyisocyanurate foam layer and an aluminum foil facer or coated glass facer adhered to each side of the polyisocyanurate foam layer and the second rigid foam insulation board has a thickness of 1½ to 2 inches and comprises a polyisocyanurate foam layer and a glass fiber reinforced foil facer material adhered to each side of the polyisocyanurate foam layer.

6. The building of claim 1 , wherein an outer edge of the first side of the first rigid foam insulation board abuts the web of the first I-joist and an outer edge of the second side of the first rigid foam insulation board abuts the web of the second I-joist, so that the outer edges are not in a spaced-apart relationship relative to web of the first I-joist and the web of the second I-joist.

7. The building of claim 2 , wherein the upper surface of the second rigid foam insulation board abuts the lower surface of the first rigid foam insulation board so that first rigid foam insulation board and second rigid foam insulation board are not in a spaced-apart relationship relative to each other.

8. The building of claim 2 , wherein the upper surface of the second rigid foam insulation board faces the lower surface of the first rigid foam insulation board such that first rigid foam insulation board and second rigid foam insulation board are in a spaced-apart relationship.

9. The building of claim 2 , wherein:
(i) the lower surface of the second rigid foam insulation board faces the upper surface of the lower flange of a first I-joist at the first side of the second rigid foam insulation board in a spaced-apart relationship, and
(ii) the lower surface of the second rigid foam insulation board faces the upper surface of the lower flange of a second I-joist at the second side of the second rigid insulation board in a spaced-apart relationship,
such that a gap is formed between the lower surface of the second rigid foam insulation board and the lower surface of the lower flanges of the first I-joist and the second I-joist, the gap having a height of 1¼ to 7 inches.

10. The building of claim 9 , wherein the outer edge of the first side of the second rigid foam insulation board abuts the web of the first I-joist and the outer edge of the second side of the second rigid foam insulation board abuts the web of the second I-joist so that the outer edges are not in a spaced-apart relationship relative to web of the first I-joist and the web of the second I-joist.

11. The building of claim 2 , wherein the second rigid foam insulation board is designed such that according to the 2018 International Residential Code® (“IRC”) Section 2603.9, compliance with the requirements of IRC Sections 2603.4 through 2603.7 is not required.

12. The building of claim 2 , wherein the combined thermal insulating value of the first rigid foam insulation board and the second rigid foam insulation board is at least R-30 determined per ASTM C 518-17 in accordance with ASTM C-1289-18.
