Abstract

A high density construction board includes a cellular body having a first planar surface and a second planar surface. A first glass facer is positioned adjacent the first planar surface and a second glass facer is positioned adjacent the second planar surface. The cellular body of the construction board includes a polyurethane, a polyisocyanurate, or a mix of polyurethane and polyisocyanurate and has a density greater than about 2.5 pounds per cubic foot and less than 6 pounds per cubic foot.

Claims (37)

1 . A high density construction board comprising:

a cellular body having a first planar surface and a second planar surface,

a first facer adjacent said first planar surface and a second facer adjacent said second planar surface,

wherein said cellular body includes a polyurethane, a polyisocyanurate, or a mix of polyurethane and polyisocyanurate and has a density greater than about 2.5 pounds per cubic foot and less than 6 pounds per cubic foot, and

wherein said first facer and said second facer are formed from materials selected from the group consisting of coated glass fiber mats, uncoated glass fiber mats, chopped glass, and combinations thereof.

2 . The construction board of claim 1 , wherein said density of said cellular body is greater than about 3 pounds per cubic foot.

3 . The construction board of claim 2 , wherein said density of said cellular body is greater than about 3.5 pounds per cubic foot.

4 . The construction board of claim 3 , wherein said density of said cellular body is between about 4 and about 5 pounds per cubic foot.

5 . The construction board of claim 1 , wherein said cellular body includes a thickness greater than about 0.5 inches.

6 . The construction board of claim 5 , wherein said thickness is from about 0.5 to about 4.5 inches.

7 . The construction board of claim 6 , wherein said thickness is from about 1.0 to about 4.0 inches.

8 . The construction board of claim 1 having an iso index of at least 175.

9 . A covered roof comprising:

a roof deck; and

a high density construction board comprising a cellular body having a first planar surface and a second planar surface, a first facer adjacent said first planar surface and a second facer adjacent said second planar surface,

wherein said cellular body includes a polyurethane, a polyisocyanurate, or a mix of polyurethane and polyisocyanurate and has a density greater than about 2.5 pounds per cubic foot and less than 6 pounds per cubic foot, and

wherein said first facer and said second facer are formed from materials selected from the group consisting of coated glass fiber mats, uncoated glass fiber mats, chopped glass, and combinations thereof.

10 . The covered roof of claim 9 , wherein said density of said cellular body is greater than about 3 pounds per cubic foot.

11 . The covered roof of claim 10 , wherein said density of said cellular body is greater than about 3.5 pounds per cubic foot.

12 . The covered roof of claim 11 , wherein said density of said cellular body is between about 4 and about 5 pounds per cubic foot.

13 . The covered roof of claim 9 , wherein said cellular body includes a thickness greater than about 0.5 inches.

14 . The covered roof of claim 9 , wherein said construction board has an iso index of at least 175.

15 . The covered roof of claim 9 further comprising a protective membrane, wherein said construction board is between said roof deck and said protective membrane

16 . The covered roof of claim 15 , wherein said protective membrane includes a polymeric membrane.

17 . The covered roof of claim 15 , wherein said protective membrane includes a bituminous or asphalt membrane.

18 . The covered roof of claim 15 , wherein said protective membrane derives from the application of hot asphalt to the roof.

19 . A method of covering a roof comprising:

applying a high density construction board to the roof, the high density construction board comprising a cellular body having a first planar surface and a second planar surface, a first facer adjacent said first planar surface and a second facer adjacent said second planar surface, wherein said cellular body includes a polyurethane, a polyisocyanurate, or a mix of polyurethane and polyisocyanurate and has a density greater than about 2.5 pounds per cubic foot and less than 6 pounds per cubic foot, and wherein said first facer and said second facer are formed from materials selected from the group consisting of coated glass fiber mats, uncoated glass fiber mats, chopped glass, and combinations thereof.

20 . The method of claim 19 , wherein said density of said cellular body is greater than about 3 pounds per cubic foot.

21 . The method of claim 20 , wherein said density of said cellular body is greater than about 3.5 pounds per cubic foot.

22 . The method of claim 21 , wherein said density of said cellular body is between about 4 and about 5 pounds per cubic foot.

23 . The method of claim 19 , wherein said cellular body includes a thickness greater than about 0.5 inches.

24 . The method of claim 19 , wherein said high density construction board has an iso index of at least 175.

25 . The method of claim 20 , further comprising the step of applying a protective membrane to the roof subsequent to the step of applying a high density construction board.

26 . The method of claim 25 , wherein said protective membrane includes a polymeric membrane.

27 . The method of claim 25 , wherein said protective membrane includes a bituminous or asphalt membrane.

28 . The method of claim 25 , wherein said protective membrane derives from the application of hot asphalt to the roof.
