Hi
The loft in my house has been boarded out for storage.
- Mineral wool insulation (200mm) in joists, boarded over with floor boards.
- Mineral wool between rafters (and pressing against felt membrane) and boarded over with plasterboard.
First of all, should the insulation from the rafters be removed due to potential condensation issues? Second is there any point to it to start with? The 200mm in the joists is keeping most if the heat in the house below and the loft space is only boarded for storage it's not lived in or heated.
I was thinking remove plasterboard & rafter insulation, replace with 25mm polystyrene board insulation between rafters, maybe another 50mm over rafters, re-plasterboard.
