Wall Vent

Abstract

The present invention is concerned with a wall vent for particular use in a cavity wall of a timber frame building, the vent comprising a tubular body having a circumferential flange at one end and a vented or meshed cover across said end, the flange being disposed at an angle to the body such that when the flange is seated flush against the outer surface of the cavity wall the tubular body slopes upwardly into the cavity to prevent the migration of rain or the like through the vent into the cavity.

1 . A wall vent comprising a tubular sidewall defining first and second ends; and a radially outwardly extending flange surrounding the first end. 
   
   
       2 . A wall vent according to  claim 1  in which the first end is provided with an apertured cover across the first end. 
   
   
       3 . A wall vent according to  claim 1  comprising one or more ribs on an exterior of the sidewall. 
   
   
       4 . A wall vent according to  claim 3  in which the one or more ribs are circumferentially disposed on the sidewall. 
   
   
       5 . A wall vent according to  claim 1  in which the flange is disposed in a plane disposed at an obtuse angle to a longitudinal axis of the sidewall. 
   
   
       6 . A wall vent according to  claim 1  in which the flange is disposed at an angle in the range of between 70° and 90°, more preferably in the range of 85° and 90°, and most preferably at 87.5°. 
   
   
       7 . A wall vent according to  claim 1  in which the apertured cover comprises an array of vents. 
   
   
       8 . A wall vent according to  claim 1  in which the apertured cover comprises a mesh adapted to prevent insects entering the vent. 
   
   
       9 . A wall vent according to  claim 1  comprising indicia on the flange to indicate the intended working orientation of the vent. 
   
   
       10 . A wall vent according to  claim 1  in which the second end of the sidewall comprises a radially inwardly extended circumferential lip. 
   
   
       11 . A wall vent according to  claim 1  in which the sidewall comprises one or more frangible portions.
