Wall size and acoustic plaster board sizes

Anonymous user 23/02/2024 - 3.12 PM

I need a wall that's 11ft 5ins long and 8ft high sound proofed, the acoustic plaster boards I'm looking at are: 2400mm x1200mmx12.5mm 2400mm x1200mmx15mm 2700mm x1200mmx12.5mm What it be better/ which is easiest/best way of doing it with regards to cutting the boards to fit length wise being as their all the same width ? The 2700mm long of which if I'm correct I will need 4 panels and their just over 8ft so need to be cut down to size. Or 5 of the 2400 which are just over 7ft at 7ft.874016 and one's going to have to be cut to make up the correct length of the other 4?' And would the 12.5mm or the 15mm be better 0r is 12.5mm pretty good at cutting noise through an adjoining wall with my neighbours, The internal wall I need sound proofing is concrete so do I also need a timber frame as well to attach the boards to ? And is it classed as as 'secondary wall? If I need a timber frame built, which I think is correct? what type of timber and sizes lengths/widths etc, and how much timber would it require to do the job of hanging the plaster board over that area? I'm going need plasterer to do the job as I can't do it myself NOT because I'm a female, :-D I could have done it in the past, I loved doing all types of DIY but due to health problems that I now have that stop me being able to even try :( Also need advice on what else I may need like how many bags/what size of plaster and tape or whatever so I can price that up too. Thanks

Are you a tradesperson and able to answer this question?

Acoustic Plasterboard is an acoustic alternative to standard plasterboard. The density of the boards is higher than that of standard plasterboard. 12.5mm. acoustic plasterboard can be used to reduce noise transmission through walls and ceilings. We would advise that this board should be used in combination with other products to achieve the maximum levels of soundproofing
