Acoustical building panel and surface covering systems utilizing the same
Described herein are building panels and surface covering systems useful for spaces requiring acoustic control and design flexibility, and methods to prepare the same. Such building panels and surface covering systems comprise an building panel having a first major surface opposite a second major surface and a side surface extending there-between, the acoustic building panel comprising a body having an upper surface opposite a lower surface and side surfaces extending there-between; backing having a first side opposite a second side and comprising denim web and a low-melt polyester bicomponent fiber; wherein the first side of the denim web backing is in contact with the upper surface of the body; and wherein the denim web backing has a web basis weight from about 1150 to about 1350 g/m 2 . In certain embodiments, building panels and surface covering systems have superior fire resistant qualities.

a body comprising an upper surface opposite a lower surface and a side surface extending there-between;
a backing having a first side opposite a second side and comprising denim web and a low-melt polyester bicomponent fiber;
wherein the first side of the denim web backing is in contact with the upper surface of the body;
wherein the denim web backing has a web basis weight from about 1150 to about 1350 g/m 2 ;
wherein the denim web is present from about 65% to about 75%, by weight of the backing; and
wherein the low-melt polyester bicomponent fiber is present from about 10% to about 35%, by weight of the backing.
2 . The acoustic building panel of claim 1 , wherein the body comprises a nonwoven material.
3 . The acoustic building panel of claim 1 , wherein the body comprises aspen wood, non-woven perforated metal, or wood.
4 . The acoustic building panel of claim 1 , wherein the body comprises aspen wood excelsior.
5 . The acoustic building panel of claim 1 , wherein the distance between the upper surface and lower surface is about 0.8 inches to about 2.5 inches.
6 . The acoustic building panel of claim 1 , wherein the low-melt polyester bicomponent fiber comprises copolyester polyethylene terephthalate/polyethylene terephthalate (coPET/PET).
7 . The acoustic building panel of claim 1 , wherein the low-melt polyester bicomponent fiber is present from about 28% to about 33%, by weight of the backing.
8 . The acoustic building panel of claim 1 , wherein the acoustic building panel further comprises a fire retardant.
9 . The acoustic building panel according to claim 1 , further comprising magnesium oxide, sodium silicate, magnesium sulfate, and calcium carbonate.
10 . An acoustic building panel having a first major surface opposite a second major surface and a side surface extending there-between, the acoustic building panel comprising:
a body having an upper surface opposite a lower surface and a side surface extending there-between;
a backing having a first side opposite a second side and comprising denim web and a low-melt polyester bicomponent fiber;
wherein the first side of the denim web backing is in contact with the upper surface of the body;
ammonium sulfate;
wherein the denim web backing has a web basis weight from about 1150 to about 1350 g/m 2 ;
wherein the denim web is present from about 65% to about 75%, by weight of the backing; and
wherein the low-melt polyester bicomponent fiber is present from about 10% to about 35%, by weight of the backing.
11 . The acoustic building panel of claim 10 , wherein the body comprises a nonwoven material.
12 . The acoustic building panel of claim 10 , wherein the body comprises aspen wood, non-woven perforated metal, or wood.
13 . The acoustic building panel of claim 10 , wherein the body comprises aspen wood excelsior.
14 . The acoustic building panel of claim 10 , wherein the distance between the upper surface and lower surface is about 0.8 inches to about 2.5 inches.
15 . The acoustic building panel of claim 10 , wherein the low-melt polyester bicomponent fiber comprises copolyester polyethylene terephthalate/polyethylene terephthalate (coPET/PET).
16 . The acoustic building panel of claim 15 , wherein the low-melt polyester bicomponent fiber is present from about 28% to about 33%, by weight.
17 . The acoustic building panel according to claim 10 , further comprising magnesium oxide, sodium silicate, magnesium sulfate, and calcium carbonate.
18 . An acoustic building panel having a first major surface opposite a second major surface and a side surface extending there-between, the acoustic building panel comprising:
