got to insulate bedroom floor which has kitchen diner below. Joist depth is a good 7 inches. Only ever used 100mm rockwool slabs for this, anyone got any better options? Can’t find the same slabs any thicker like 150mm. Cheers.
Why not get some 50mm slabs and double deck them with your 100mm ones?got to insulate bedroom floor which has kitchen diner below. Joist depth is a good 7 inches. Only ever used 100mm rockwool slabs for this, anyone got any better options? Can’t find the same slabs any thicker like 150mm. Cheers.
Adding mass to any space is going to reduce noise travel (sound-proof booths are lined with lead). Double boarding will help quite a lot. The thicker and heavier the better.Also, double boarding it - worth the effort? (Not soundbloc just normal board)

So you are replacing the downstairs ceiling?
The Rockwool slabs I linked to above are the sound insulation variety.You can get Acoustic Rockwool slabs which are denser than regular rockwool. I’m not sure what sizes are available but you can obviously stack them. A bit harder from below i guess. Beware of burying cables if you try to squeeze in too much.
Of course double plasterboard, or using soundblock plasterboard, will also help.
If there is currently nothing there at all then I think 100m of acoustic wool will make a huge improvement.
