After some advice regarding insulation between floors in a full refurb of our recently purchased house.
Under the floors upstairs would it be suitable to lay 100mm of rockwool between joists? Or is it recommended to use an insulation with acoustic properties too?
Downstairs is a mixture of solid and suspended floors. There is good ventilation under the suspended floors, is it recommended to have any sort of insulation under the floorboards to stop drafts etc coming up?
We also have a single story kitchen extension with a pitched roof. Everything is stripped currently, with only a newly screeded floor in place and ceiling joists exposed. I would obviously like to insulate the ceiling to stop the heat going in to the ceiling void, but I also want to board out some of the area too. Would 100mm rockwool between joists with chipboard flooring above be sufficient?
Thanks in advance.
