Wall soundproofing Help Needed

Dear Sirs,

I live in a semi detached bungalow built circa 1963, the adjoining bedroom wall of which consists of a single non cavity wall made of breeze blocks laid on their side.. The width of the wall is therefore approx 30mm wide. Unfortunately this provides seemingly zero suppression to the noise made my neighbors. I generally hear talking, and doors slamming, however of late added to this is the noise of two barking dogs. I really need to cure this problem.

Previously in the living room, either side of a chimney breast I was advised to stick two layers of 14mm sound proof plaster board on both walls. I did exactly what I was told and glued one board directly to the wall and the other directly on top of that. This solution has proved totally ineffective. Your comments would be appreciated.

If you could advise me as to a suitable solution to by current bedroom wall problem, I would be grateful.

Please understand that I would like to cure this problem in “one hit” I do not want to end up with a ineffective solution as in my living room having gone to an enormous effort to fit a system which does not work, I mean no offence by this remark.

I will endeavor to take the necessary wall measurements this evening in order to provide you with further information.

I look forward to your response.

    Thank you for your enquiry and we can appreciate the problem you are having with noise through a single skin, lightweight party wall. It is most unlikely you will be able to eliminate the noise problem completely due to the following reasons.

    1. Flanking noise will be a problem skirting round the outside structural walls that will have a cavity with the inside skin most likely low density blocks.
    2. There is a fireplace with a chimney breast within the room. Unless the front of the fireplace is bricked up, noise will still come through.

    Assuming the fireplace is bricked up, quite good results can be achieved by installing our Studio Wall System on either side of the chimney breast. Ptior to this and in addition, if the floor is timber suspended, a couple of layers of 2mm SBM5 Soundproofing Mat should be laid over the floor to help block flanking noise through the floor. Finally, it is assumed that normal fibreglass loft insulation is already installed between the joists in the loft but if not, would help if it was. The ceiling itself is probably just one layer of thin plasterboard. This should be upgraded by adding another layer of 15mm high density Acoustic Plasterboard with our SoundBlocker Membrane sandwiched between the two layers.

    It was not us that would have advised you to install the plasterboard so far but it will be better to leave it in place now that it is there.

    This system will take up about 5.5 inches of space. Anything less will not be as effective. If you think this system will suit you, get back to us with the dimensions of the walls and floor/ceiling and we will be pleased to give you our best price to supply and deliver your requirements.
