What insulation can we have between bedroom and Kitchen below it? Can we put rockwool in Ceiling?

Hi all
We are having a new kitchen. Initially, it was just going to be the kitchen and new downlights in the kitchen ceiling but we have discovered that there is no insulation in the kitchen ceiling (see photo)
which explains why when we are in bed we can hear a pin drop in the kitchen below. So, we are ripping the kitchen ceiling down soon and obviously replacing it. What insulation is best to use? We cant use slabs etc because its a big kitchen and there's loads of Water pipes, central heating pipes, wires etc. I assume there will be some fire regulations on what can/cannot be used etc and I also assume there are products that are designed for this type of project.
Thanks in advance.

One doesn't usually put insulation between the ceiling & floor unless it is an acoustic batt to limit noise transmission. Acoustic insulation is a complex subject, often with some very expensive & technical solutions. But the basics is to add mass and avoid using large spans of thin materials that could act like a drum skin.That said, when I replaced my kitchen ceiling, I filled the void with fibreglass loft insulation. Primarily to reduce any cold draughts in the void, but also in an attempt to reduce noise. Debatable as to whether it made any difference to heat loss in the room above, although it did reduce the perceived noise in the room a little. In conjunction with a fire resistant plasterboard, the insulation will provide a little bit more protection in the event of the unthinkable.Her courage will change the world.

If you do not mind doing the work from above, once you have kitchen ceiling in place and downlighters have protector hoods in place you could lift some floorboards above and put loose fill insulation in. Loose fill cellulose claims to be green and fire retardant, with this type of product you should be able to get it into all the nooks and crannies which will cut down on noise from below.1

Also just be aware that cables running in insulation normally need to be thicker diameter cable than those in free air due to the heat build up, and it might be worth asking a sparky if any need changing whilst the ceiling is down.
(Particularly the case if there are any 6mm cables to cookers or power showers or 2.5mm cables to sockets).1
