Composite board containing glass fiber mat

Abstract

A composite board including: at least one glass fiber mat having an upper surface and a lower surface; a foam layer attached to the glass fiber mat; and a first binding composition applied to the upper surface of the at least one glass fiber mat and a second binding composition applied to the lower surface of the at least one glass fiber mat, the first and second binding compositions being the same or different compositions.

1 . A composite board comprising:
 at least one glass fiber mat having an upper surface and a lower surface;   a foam layer attached to the glass fiber mat; and   a first binding composition applied to the upper surface of the at least one glass fiber mat and a second binding composition applied to the lower surface of the at least one glass fiber mat, the first and second binding compositions being the same or different compositions.   
     
     
         2 . The composite board according to  claim 1 , wherein the first binding composition penetrates into the glass fiber mat beyond the upper surface, and the second binding composition penetrates into the glass fiber mat beyond the lower surface. 
     
     
         3 . The composite board according to  claim 1 , wherein the air permeability of the at least one glass fiber mat on which the first and second compositions have been applied, is such that it takes at least 300 seconds for 300 cubic centimeters of air to pass through 1 square inch of the glass fiber mat. 
     
     
         4 . A method of making a composite board comprising:
 applying a first binding composition to an upper surface of at least one glass fiber mat;   applying a second binding composition to a lower surface of the at least one glass fiber mat, wherein the first and second binding compositions are the same or different compositions; and   attaching a foam layer to the at least one glass fiber mat.   
     
     
         5 . The method of making a composite board according to  claim 4 , further comprising applying the first and second binding compositions with first and second applicator roll. 
     
     
         6 . The method of making a composite board according to  claim 4 , further comprising applying the first and second binding compositions to the at least one glass fiber mat with a plurality of spray nozzles. 
     
     
         7 . The method of making a composite board according to  claim 4 , further comprising:
 feeding the at least one glass fiber mat along a process line;   injecting a thermosetting polymer foam on the upper surface of the glass fiber mat;   applying heat to the thermosetting polymer foam until the thermosetting polymer foam rises, cures, and attaches to the upper surface of the glass fiber mat.
