Acoustical ceiling tile

Abstract

A ceiling tile includes a first layer and a second layer. The first layer includes first and second planar surfaces. The second layer is comprised of at least ten (10) percent fiberglass by weight and is joined adjacent to the first planar surface.

1 . A ceiling tile comprising: 
 a first layer having first and second planar surfaces;    a second layer comprised of at least ten (10) percent fiberglass by weight joined adjacent the first planar surface.    
     
     
         2 . The ceiling tile of  claim 1 , further including a third layer comprised of at least ten (10) percent fiberglass by weight joined adjacent the second planar surface.  
     
     
         3 . The ceiling tile of  claim 2 , further including a first adhesive layer between the second layer and the first planar surface and a second adhesive layer between the third layer and the second planar surface.  
     
     
         4 . The ceiling tile of  claim 3 , wherein the adhesive is a thermoplastic bonding agent.  
     
     
         5 . The ceiling tile of  claim 3 , wherein the adhesive is a hot melt adhesive.  
     
     
         6 . The ceiling tile of  claim 1 , wherein the first layer comprises a foam core.  
     
     
         7 . The ceiling tile of  claim 1 , wherein the ceiling tile is less than 0.6 inches thick.  
     
     
         8 . The ceiling tile of  claim 1 , wherein the ceiling tile has a first axis and a second axis, wherein the first axis is between five (5) and eight (8) feet long and the second axis is between three (3) and four (4) feet long.  
     
     
         9 . The ceiling tile of  claim 1 , wherein the ceiling tile has a first axis and a second axis, wherein the first axis is about eight (8) feet long and the second axis is about four (4) feet long.  
     
     
         10 . An acoustical ceiling tile comprising: 
 a foam panel having first and second surfaces, the foam panel comprised of an open-cell melamine foam; and    a first laminated layer impregnated with fiberglass and joined to the first surface of the foam panel.    
     
     
         11 . The acoustical ceiling tile of  claim 10 , further including a second laminated layer impregnated with fiberglass and joined to the second surface of the foam panel.  
     
     
         12 . The acoustical ceiling tile of  claim 10 , wherein the first laminated layer is joined to the first surface by an adhesive therebetween.  
     
     
         13 . The acoustical tile of  claim 11 , wherein the second laminated layer is joined to the second surface by an adhesive therebetween.  
     
     
         14 . The acoustical tile of  claim 13 , wherein the adhesive is a hot melt or a pressure sensitive adhesive.  
     
     
         15 . The ceiling tile of  claim 10 , wherein the foam panel is less than 0.6 inches thick.  
     
     
         16 . The ceiling tile of  claim 10 , wherein the foam panel is about 0.4 inches thick.  
     
     
         17 . The ceiling tile of  claim 10 , wherein the foam panel has a first axis and a second axis, wherein the first axis is between five (5) and eight (8) feet long and the second axis is between three (3) and four (4) feet long.  
     
     
         18 . The ceiling tile of  claim 10 , wherein the foam panel has a first axis and a second axis, wherein the first axis is about (eight) 8 feet long and the second axis is about four (4) feet long.  
     
     
         19 . A ceiling tile comprising: 
 two opposed layers surrounding a foam core made from an open-cell melamine foam, the two opposed layers comprised of a material having at least ten (10) percent fiberglass by weight.    
     
     
         20 . The ceiling tile of  claim 19 , wherein the two layers are joined to the foam core with an adhesive layer therebetween.
