I am renovating a loft into a bedroom, and will share a common wall with next door neighbor, nice people who also may see movies or TV. How do I best insure that there will be no noise. At present - there is only a cinderblock wall between us. What do I have to add and how? They would also be willing to add on their side also. thanks

    There is what you call a sound board. it will stop the noise coming in to your side of the apartment completely

    Soundboard will not work. It has one use only and that is as flooring underlayment. What you need is a so-called furring wall that is framed in front of the demising wall without attaching to it. Stuff the cavity with fiberglass batt insulation.

    Hi David, I also have such problem. I have brick/cemented wall attached to the same of my neighbours left and right. So the problem walls must be insulated. I will have to cut down part of the walls to make a space for the new insulation addition. So I am looking for something ( preferably) thin but effective material. I hate to cut a lot off my walls, you can imagine the mass. On the other hand, I do not want "just to attach" the insulation, because I can do not want to loose space of my rooms.It is not too large. I would be so grateful if you could advice me on this? Thank you so much for your kind attention to my problem, Denise , Indonesia ( denise9id@gmail.com)

    Hi Denise, do not modify a brick wall without having a written opinion from an engineer or architect. You will lose some space by building a furring wall that is unattached. About 11 centimeters at least. Stuff the cavity with fiberglass wool. Good luck with your project. --david

    Hi David, thanks so much for your kind advice. One more thing : what material for the finishing is the best?
    And what is the "RC channel". Is it usable for my case?
    I will try to consult with somebody, but it is not so easy to fine an experienced one . So your info will make me more confident to discuss. With many thanks again..Denise

    I would use gypsum drywall for finishing. RC channels only work where there is a min. 9 cm cavity behind it, walls or ceilings. best, --david
