I just wondered what the black cardboard was & why it was there? My gut feeling is to hack it all off, leave it for a couple of months to dry out (hey, brick feature wall, anyone?;-), and internally insulate. I've only got room for 25mm of insulation, but it'll prob be better than cardboard (although I did wonder about the airspaces?)

Thoughts on black stuff & putative plan much appreciated :-)

Ps anyone who replied to my posts on mould; thanks :-) I'm ventilating, heating more & dehumidifying .]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140595#Comment_140595 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140595#Comment_140595 Sat, 24 Mar 2012 22:05:18 +0000 nbishara http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140596#Comment_140596 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140596#Comment_140596 Sat, 24 Mar 2012 22:10:01 +0000 tony http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140600#Comment_140600 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140600#Comment_140600 Sat, 24 Mar 2012 22:21:47 +0000 fostertom http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140608#Comment_140608 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140608#Comment_140608 Sun, 25 Mar 2012 00:53:23 +0000 Nick Parsons http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140612#Comment_140612 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140612#Comment_140612 Sun, 25 Mar 2012 07:22:14 +0100 Joiner http://newton-membranes.co.uk/damp-proofing/

The ridges are a key for plaster. There's another similar product out there, too.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140613#Comment_140613 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140613#Comment_140613 Sun, 25 Mar 2012 07:36:59 +0100 Cav8andrew
and to provide channels for air movement/water drainage behind the finished plaster

As already said it's main use was for tanking of basements, many early conversions /renovations in Bath used this method.

My Dad covered a garden shed in it, it survives to this day, just.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140614#Comment_140614 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140614#Comment_140614 Sun, 25 Mar 2012 07:51:57 +0100 Beau

If it's a single brick wall in an exposed location companies like Celotex/Kingspan typically recommend installing a membrane before insulation. See their sdvice on garage conversions.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140634#Comment_140634 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140634#Comment_140634 Sun, 25 Mar 2012 16:17:24 +0100 nbishara

I may have discovered at least one reason why the walls is damp. The render on the other side has been cracked for a while & I was assured that it was fine. However, it looks like its now cracked along the "score lines" (it has a mock block effect), to the point where there a thin line of moss growing out. That's not good, is it?!

Not sure that sticking polystrene on the outside is the best thing to do here at this stage as you are talking about a lot of work which then needs undone at a later date, the water at this stage will be getting in along the render cracks (especially if the cracks are big enough to be growing moss) and tracking down and soaking the inside of the wall. One way or another the render needs to come off where it has cracked and be re-rendered.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140671#Comment_140671 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=8856&Focus=140671#Comment_140671 Mon, 26 Mar 2012 15:27:29 +0100 nbishara hoping to build an extension over it - & then itll be an internal wall. Anyone got any dofer (do for now) suggestions that would keep the internal wall dry & insulated. Will cracked render damage the structural integrity of the wall at all?

Thanks,
