Hello, I need some advice.
I'm converting a small study into a bedroom for my grandson.
It's separated from the living room by a stud partition wall which permits passage of TV and radio noise.
I've filled the cavaties of the wall with an expanding foam, but the soundproofing is still not adequate.
Would application of your Acoustic Foam to the bedroom wall significantly improve soundproofing?
From reading the description on your website, the product seems to be designed to prevent emission of noise from a small space rather than prevent its penetration into a small space.
Can this work in reverse?-
Also, would the 12 mm thickness be adequate, or would I do much better to use the 25 mm version?
It's a rather small space and I would like to encroach on it as little as possible, hence the unsuitability of your other wall products requiring two layers of plasterboard etc.
Thank you.
Kind regards
Will expanding foam soundproof a wall?

Expanding foam within the cavities of the stud wall may have made the sound insulation worse because it stiffens up the structure. For best results you should use AMW Acoustic Mineral Wool or the superior SoundBlocker Quilt that we can supply. As you mention that space is at a premium, the best you can do now is to add a 2mm layer of SBM5 Soundproofing Mat to both sides of the stud wall with a 15mm layer of high density Acoustic Plasterboard screwed over the top. The installation of foam or any other sound absorbing material onto the outside of the wall will not improve the soundproofing of the wall but will reduce reveberation within the room in which it is applied.
