Abstract

Provided are wallboard panels that include a foam material layer and a core material, with one or more sheets of facer material and/or one or more sheets of backing material. The foam material layer may include one or more pores having an open pore geometry. Additionally, provided are methods of manufacturing such wallboard panels.

First claim

1 . A wallboard panel, comprising:
a core, comprising a foam material layer comprising one or more pores having an open pore geometry, wherein the foam material layer comprises a first side and a second side, wherein the first side and second side of the foam material layer have been treated with a cementitious core material; a facer, comprising one or more sheets of facing material; and a backer, comprising one or more sheets of backing material, wherein the core is sandwiched between the facer and the backer.

2 . The wallboard panel of claim 1 , wherein at least 0.01% to about 100% of the one or more pores comprises an open pore geometry.

3 . The wallboard panel of claim 1 , wherein the foam material layer has a thickness ranging from about 6 mm to about 10 mm.

4 . The wallboard panel of claim 1 , wherein the cementitious core material penetrates the one or more pores of the foam material layer thereby securing the cementitious core material to the foam material layer.

5 . The wallboard panel of claim 1 , wherein the cementitious core material does not penetrate through the full thickness of the foam material layer.

6 . The wallboard panel of claim 1 , wherein the foam material layer comprises polyurethane, polyester, polyethene, ethylenevinylacetate, polypropylene, polyvinylchloride, polysiloxane, polystyrene, polyisocyanurate, nitrile, vinyl nitrile, ethylene propylene diene monomer, neoprene, styrene butadiene rubber, phenolic foam, and combinations thereof.

7 . The wallboard panel of claim 6 , wherein the foam material layer comprises a reticulated ester-based polyurethane.

8 . The wallboard panel of claim 6 , wherein the foam material layer comprises an ether-based polyurethane.

9 . The wallboard panel of claim 6 , wherein the foam material layer comprises a reticulated polyester.

10 . The wallboard panel of claim 6 , wherein the foam material layer comprise an impregnated polyurethane.

11 . The wallboard panel of claim 1 , wherein the foam material layer comprises melamine.

12 . The wallboard panel of claim 1 , wherein the wallboard has a thickness of about ⅝″.

13 . The wallboard panel of claim 1 , wherein the foam material layer has a thickness ranging from about 0.01 mm to about 50 mm.

14 . The wallboard panel of claim 1 , wherein the cementitious core material comprises gypsum.

15 . The wallboard panel of claim 1 , wherein the cementitious core material primarily contains gypsum.

16 . The wallboard panel of claim 1 , wherein the cementitious core material does not penetrate through the full thickness of the foam material layer.

17 . The wallboard panel of claim 1 , wherein the wallboard panel has a thermal conductivity of from 0.03 W/m*K to 0.5 W/m*K, a thermal resistance of from 0.03 K*m 2 /W to 0.3 K*m 2 /W, and/or an R-value of from 0.4 to 5.

18 . A method of making a wallboard panel, the method comprising:
formulating a gypsum slurry; dispensing the gypsum slurry on a first side of a facing material sheet, dispensing a foam material layer on the gypsum slurry; dispensing the gypsum slurry on a second side of the foam material layer; and rolling one or more backing material sheets over the gypsum slurry, wherein the one or more facing material sheets comprise a backer.

19 . The method of claim 18 , wherein the facing material sheet comprises paper, paperboard, glass mat, or glass mesh.

20 . The method of claim 18 , wherein the one or more backing material sheets comprises paper, paperboard, glass mat, or glass mesh.
