sjp Posted May 3, 2010 Share Posted May 3, 2010 I'm about to build a new hen house I've ripped the studs to size for the walls I'm going to use UPVC shiplap for the outer wall and upvc flatboard for the inner wall that will give me a 30mm cavity should I insulate the cavity or not? I'll allow for ventilation through the walls either way and one face will have ply wood under the upvc all timber and upvc are off cuts from work that just happen to end up in the garage instead of the skip Quote Link to comment Share on other sites More sharing options...
