Hi all, I've got loads of thick sheets of cork insulation left from various limecrete slab floor jobs and wanted to put them up in my utility room loft area. It butts up against the valted ceiling of my kitchen so it'll definitely help to have some insulation on the cold side. Has anyone used cork boards before? If so, what did you use to fix them up with? They are pretty delicate so I was thinking about screwing them loosely with some large penny washers to pull them in. Bare in mind I need to get rid of the boards and they are all free so it makes sense to use them. Thanks!
