I'm looking at installing insulation under my suspended floor. The joists are 120mm deep. My plan is to use loft insulation held in place by netting.
Loft insulation isn't readily available in 120mm thickness though, so I'm looking at 100mm or 150mm. Which is best? 100mm will leave a gap immediately under the flooring, but if I pack in 150mm it'll be quite dense so I'm wondering if it might trap moisture?
