Dougy Posted July 16, 2018 Report Share Posted July 16, 2018 Not an expert so just ignore the post lol but i cant see the point, your creating a cavity anyway with the shiplap no doubt being fixed to battons. Im boarding mine from the inside with celotex and MDF this year hopefully. Quote Link to comment Share on other sites More sharing options...
haynes Posted July 16, 2018 Report Share Posted July 16, 2018 Id probably say dont bother. But i would use a breathable membrane on the top and bottom. To stop birds and insects nesting between the gap Quote Link to comment Share on other sites More sharing options...
Rob525 Posted July 16, 2018 Report Share Posted July 16, 2018 (edited) Personally i would put a damp course in the block and use pressure treated tile batton to make a square/rectangle on the wall (going no lower than the dampcourse) then fix your horizontal or vertical batton in the middle of the square to essentialy make a kind of ladder. When you clad it, it will be sealed all the way arround to stop birds nesting and because its above the dpc the batton can go straight to the brickwork Just what i would do but there are other ways and probably better!

scotslad Posted August 12, 2018 Report Share Posted August 12, 2018 Would he not need a DPM behind the battens he fixes on to the wall? So dampness couldn't transfer throu the batten into the wall behind Quote Link to comment Share on other sites More sharing options...

So dampness couldn't transfer throu the batten into the wall behind It wouldn't be a bad idea on a single skin masonry wall, especially a 4" one. If it was a cavity wall then no need for a breather membrane Quote Link to comment Share on other sites More sharing options...
