Structural Member Comprising Sound Insulating Layer

Abstract

The present invention provides a structural member comprising a beam and, attached thereto, a sound insulating layer comprising a non-foamed, polymeric material. A method of obtaining such members is also provided.

1 . A structural member comprising a beam and, attached thereto, a sound insulating layer comprising a non-foamed, polymeric material. 
   
   
       2 . A member according to  claim 1 , wherein the member comprises a wooden beam. 
   
   
       3 . A member according to  claim 1 , wherein the member comprises a metal beam. 
   
   
       4 . A member according to  claim 1 , wherein the polymeric material comprises a mineral filler. 
   
   
       5 . A member according to  claim 1 , wherein the polymeric material is an elastomeric material. 
   
   
       6 . A member according to  claim 1 , wherein the polymeric material comprises rubber or PVC. 
   
   
       7 . A member according to  claim 1 , wherein the sound insulating layer is attached to a face of the beam. 
   
   
       8 . A member according to  claim 1 , wherein the sound insulating layer is attached to opposed faces of the beam. 
   
   
       9 . A member according to  claim 1 , wherein the sound insulating layer is attached directly to the beam. 
   
   
       10 . A member according to  claim 1 , wherein the sound insulating layer is attached indirectly to the beam. 
   
   
       11 . A method of producing a structural member of  claim 1 , which comprises attaching a sound insulating layer comprising a non-foamed, polymeric material to a beam. 
   
   
       12 . A method according to  claim 11 , wherein the beam is selected from a wooden beam and a metal beam. 
   
   
       13 . A structure comprising a structural member including a beam and, attached thereto, a sound insulating layer comprising a non-foamed, polymeric material. 
   
   
       14 . A structure according to  claim 13 , which is a wall or floor structure. 
   
   
       15 . A structure according to  claim 14 , which is a partition wall structure. 
   
   
       16 . A structure according to  claim 13 , which comprises plasterboard. 
   
   
       17 . A method according to  claim 11 , wherein the material is selected from the group consisting of a mineral filler, an elastomeric material and a material comprising rubber or PVC.
