BUILDING MATERIALS COMPRISING NON-WOVEN WEBS Abstract A mixture of binder and fibrous material is introduced into the upper regions of a mat-forming zone. The mixture is intersected by a horizontally or upwardly directed air stream and entrained therein, then layered onto at least one foraminous wire by exhausting the entraining air through said foraminous wire or wires. By reducing turbulence and by controlling the manner in which the particulate matter is deposited upon the foraminous wires, uniform non-woven webs can be obtained which may be used in a variety of ways to form versatile building products.
