Hi mike,Edit: When we have our roof replaced I am seriously considering using superquilt over rafters.
absolutely agree Kev, I do exactly that on roof insulation with PIR plasterboard over it to prevent bridging. I haven't used superquilt over the rafters yet though. You can lay it under or over rafters.Hi mike,
A properly done celotex job inbetween the rafters, with expanding foam to any gaps, even small ones, then foil tape across all timber joints and butt joints will work wonders.... but the key is to take the time to make sure its dont properly. Some people undercut the edges to get it in easier, but basically reduce the insulation value by doing so
