Acoustic building panels
Described herein is an acoustic building panel having a first major exposed surface opposite a second major exposed surface and a side exposed surface extending there between, the acoustic ceiling panel comprising: a body comprising a first major surface opposite a second major surface and a side surface extending between the first and second major surfaces, the body being air-permeable; and an attenuation coating applied to the first major surface of the body; wherein a first portion of the second major exposed surface of the acoustic building panel is formed by the first major surface of the body and a second portion of the second major exposed surface of the acoustic building panel is formed by the attenuation coating.
1. An acoustic building panel having a first major exposed surface opposite a second major exposed surface and a side exposed surface extending there between, the acoustic ceiling panel comprising:
a body that is air-permeable, the body comprising a first major surface opposite a second major surface and a side surface extending there between, the side surface comprising:
a lower edge portion adjacent to the first major surface; and
an upper edge portion adjacent to the second major surface;
an attenuation coating applied to the first major surface, the attenuation coating applied in a plurality of discrete attenuation regions, each discrete attenuation region separated from adjacent attenuation regions by at least a portion of the body;
wherein each discrete attenuation region is separated from the side surface such that a perimeter on the first major surface is free from the attenuation coating and is defined around the plurality of discrete attenuation regions; and
wherein a first portion of the side exposed surface of the acoustic building panel is formed by the upper edge portion of the side surface of the body, and a second portion of the side exposed surface of the acoustic building panel is formed by the lower edge portion.
2. The acoustic building panel according to claim 1 , wherein the side exposed surface has an overall height, the first portion has a first height, and the second portion has a second height, wherein the summation of the first height and the second height is substantially equal to the overall height of the side exposed surface.
3. The acoustic building panel according to claim 2 , wherein a ratio of the second height to the first height ranges from about 1:1 to about 10:1.
4. The acoustic building panel according to claim 1 , wherein the side surface comprises a bevel that is adjacent to the second major surface of the body.
5. The acoustic building panel according to claim 4 , wherein the bevel overlaps with the first portion of the side exposed surface of the acoustic building panel and the second portion of the side exposed surface of the acoustic building panel.
6. The acoustic building panel according to claim 5 , wherein the bevel fully overlaps with the first portion of the side exposed surface of the acoustic building panel and partially overlaps with the second portion of the side exposed surface of the acoustic building panel.
7. The acoustic building panel according to claim 1 , wherein the body is formed of a fibrous material.
8. The acoustic building panel according to claim 7 , wherein the fibrous material comprises an inorganic fiber selected from one or more of fiberglass, mineral wool, rock wool, and stone wool.
9. The acoustic building panel according to claim 1 , wherein the body exhibits an NRC value of at least 0.7.
10. The acoustic building panel according to claim 1 , wherein the attenuation coating comprises a polymer binder and a filler.
11. The acoustic building panel according to claim 2 , wherein the upper edge portion of the body has a third height and the lower edge portion has a fourth height, and wherein the first height and third height are not equal and wherein the second height and the fourth height are not equal.
12. A ceiling system comprising:
a ceiling grid comprising a plurality of first members and a plurality of second members, the first and second members intersecting one another to define a plurality of grid openings;
a plenary space above the ceiling grid;
a room environment below the ceiling grid; and
the acoustical building panel according to claim 1 mounted to the ceiling grid and positioned within the grid opening;
wherein the second major exposed surface of the acoustical building panel faces the plenary space.
13. The ceiling system according to claim 12 , wherein the side exposed surface of the acoustic building panel at least partially overlaps with the ceiling grid in a horizontal direction.
