Insulating internal floor of 1978 house.
Posted: Sun Dec 03, 2023 9:01 am
I want to insulate between the chipboard bedroom floors and ceilings. I've been told that a roll of Knauf loft insulation should do the trick. The other product I was considering (seems better for sound) is Knauf Rocksilk flexible slabs. My question is whether I need to net either product or whether I can get away with just laying the material in between the joists. I don't know how heavy either material is. I also don't know how thick the layer needs to be. The loft above is insulated, so this is just an extra layer of insulation between floors. Any advice, must appreciated!
