I'm in the process of re-decorating a small back bedroom and am replacing some damaged floorboards in the process, prior to having a carpet put in
The thing is that below this bedroom is the bathroom - it's a Victorian house with downstairs bathroom - so I'm wondering about putting some insulation underneath the floorboards.
I've read that if I want to use fibre insulation it should be suspended in netting that is attached to the joists. Why is this? Does it need netting or can I just push it along between the joists? There's board nailed to the underside of the joists so the insulation would just rest on this. Would that be OK?
