Also, do I need to include any sort of membrane before I batten and fix my timber cladding? Is so, what would be best? I have a large roll of Visqueen but would I be better with something breathable?]]> External insulation of block wall https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=483&Focus=4772#Comment_4772 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=483&Focus=4772#Comment_4772 Mon, 16 Jul 2007 21:56:45 +0100 Mike George External insulation of block wall https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=483&Focus=4773#Comment_4773 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=483&Focus=4773#Comment_4773 Mon, 16 Jul 2007 22:04:56 +0100 nigel
I would use a breather paper between the insulation and the cladding. Any air movement will reduce the effectiveness of the insulation.
You could alternatively fill any voids with foam filler.]]> External insulation of block wall https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=483&Focus=4775#Comment_4775 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=483&Focus=4775#Comment_4775 Mon, 16 Jul 2007 22:36:19 +0100 Mike George ]]> External insulation of block wall https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=483&Focus=4779#Comment_4779 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=483&Focus=4779#Comment_4779 Mon, 16 Jul 2007 22:59:33 +0100 Chris Wardle
