Hi,
I'm currently doing a cavity build and I'm not sure if to use cavity closers or not. My cavity insulation is Celotex 75mm and was wondering if I could just cut a 100mm slab, my cavity is 100mm, and use that to close the cavity around the door and window.
Having a search on here, there were some old posts where some people do that and some swear by cavity closers but there was no definitive answer.
Would I be fine closing the cavity with a 100mm cut insulation board? The inside of the build is going to be plasterboarded if that decides anything and I have brick on the outside leaf but only on one side, the other 3 walls are block on the outside leaf and will be painted to seal them.
Thank you
