    Hi all

    Would really appreciate any advice from people with experience in the above. I bought a 1940’s 1st floor maisonette a year ago and the soundproofing is terrible, can hear the family below cough, talk, laugh etc and when there’s music on forget about it! It’s really distressing now. Initially we refurbished and we placed some high density 2mm soundproofing matting down over the floorboards (1 layer in most rooms, 2 layers in the bedroom) but it hasn’t worked too well! It has come to the stage where where the only option is sell or lift up all the floorboards, new floors, skirting doors etc and fill in between the joists. Has anybody got good advice as there is so much on the internet mostly from people selling their own products. Is acoustic quilt better for airborne noise than mineral wool? Any advice would be appreciated, I have good tradesmen to do the work but soundproofing is not their speciality

    Did a job converting upper floor of a woodworking workshop to residential area. Regs. stated 4" polystyrene sound & 1/2 hour fire. Its maybe impracticable for you, but it works.

    Airbourne sounds can be a problem from a flats below, can't see how a 2mm product will reduce the noise
    There are products like Knauf Earthwool Acoustic Roll, which are denser than ordinary mineral insulation & will seriously reduce the noise, but you have you lift the floor to install, you could then lay an acoustic subfloor like DECKfon which is Tongue & Groove chipboard with a layer of acoustic resilient layer, various thicknesses available,when laying it you also use perimeter edging strip edge of room,like Yelofon FS Strip it eliminates the transfer of sound between walls and the new acoustic flooring being laid,before laying your finish flooring like laminate, carpert,etc.

    Sell.

    You would ideally want to do works in your floor AND treatments to the ceiling below.

    You could ask if they want to share the cost for the solution because if you can hear them below, they cam hear YOUR steps, creaking doors, kitchen cupboards slamming etc...

    Can't do work from below,as you need to isolate your floors from the noise, I suppose you could overboard your neighbour ceiling,(highly unlikely your neighbour would allow this) but it won't stop or completely reduce all the noise.
    The work isn't going to be cheap, so I agree sell the place.
