Now I am not sure how to insulate/ detail this. Above the door there is a flitch plate beam door, thus no stud void for PIR like the rest of the timber frame. For this reason, I am particularly concerned with condensation risk in this area. Even though we don’t have the heating on yet there was already condensation on the back of the multi-foil (lucky the VCL seemed to be doing its job and the timber was dry.)

There is only about 25mm depth in the reveals, so I am considering 12mm PIR, then 12mm plasterboard. I am also considering removing the multi-foil from the wall above the door and replacing this with 50mm insulation-backed plaster board, and a new VCL?

Does anyone have any advice on how to insulate door reveals/ heads when there is little space?

Many Thanks]]>

it's a bugger to cut though - it blunts blades quickly, you need plenty of jigsaw blades so you can change the blade after a couple of cuts.]]>

Do you have multi foil insulation?]]>

Could you describe what it's really like? Perhaps it's the board facing that kills blades?]]> Detailing Bifold door reveal insulation to avoid condensation http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17947&Focus=303361#Comment_303361 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17947&Focus=303361#Comment_303361 Mon, 18 Sep 2023 11:56:05 +0100 Dominic Cooney http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17357

It could be the board that blunts the blade. I have offcuts and am happy to send you a piece for your interest. I gave a piece to my mate Gaz, who works on a building site, to show his colleagues - he said they passed it around at brew time like a piece of moon rock.]]>

It's basically aerated sand dust, so perhaps it's quite abrasive.]]>
