Hi, anyone recommend suitable sound insulation to go in Ist floor
6inch joist void - kitchen below, w/proof plasterboard onto bottom of joists and w/resist chipfloorboarding on top. Bathroom above so looking for something w/proof and 2inchs thick, also I heard there is a product to lay between joist top and floorboard which cuts down mechanical noise transfer. Any info would be great.- posted
