Hi All



I all already have a room where we have our set up but are looking to kit it out a bit and get it to the next step. As This room is already built is there any way of soundproofing this room without ripping out the old plaster boards and fitting in new one's?

I Have heard of this new plaster that just goes over the old stuff and the will soundproof the room!

And what will be the best way to soundproof the ceiling/bedroom floor??

Hi Jay,

If you need to leave the walls and ceilings alone, and can only add, then you'll want to damp the surfaces and add mass. Please don't consider adding furring strips to the existing plasterboard. This will create a triple leaf and potentially cause additional problems.

Search the forum for green glue, this can be used to attach a second layer of plasterboard, the glue being the "damper" to give you better results than a second layer of board alone.

Thanks guys

Is green glue the best way to go about this ? or should i consider just re plastering the room for scratch

[mattym]

there is no plaster that will soundproof, or at least not that ive heard of

[JayMann]

What would you recommend i do if i was to start fresh ??

[mattym]

i would go with the green glue option, but research more before you make the choice

[JayMann]

Still have no idea how to do this! So i lay a layer of green glue on top of the old plaster bored and then a new layer of plaster bored on top of that is this right ??


Sorry for being so dumb but this is all new to me if i was starting from fresh then i guess it would be much easier


Next thing what bored do i go for ????

yes thats right, make sure you sell the edges and thats it, use the same board as you already have, which will be standard plasterboard i would think, screw the board in place as normal and then finish as desired

[JayMann]

Thanks mate


One more thing How do i sell the edges what do i use ? and when you say edges is that the edges of where the boards meet or in the corners of the room ??

Will Acoustic Plasterboard be better of the job then standard plasterboard?

if so do i go for 12/15mm borad


Can anyone recommend a good place to buy from i just found this site http://www.soundstop.co.uk/store/products.php


Thanks Jay

I used decorators caulk, it is available from B&Q etc for about £1.20 per tube

[JayMann]

So you use decorators caulk for the corners i'm guessing ???

Yes, I then used plastertape on top of all the joints before they were skimmed

[JayMann]

cool cool where can i get green glue from just googled it but all i get is the USA site

[Londondecca]

The distributors are http://www.rpg-europe.co.uk/, helpful and friendly people

Acoustic Plasterboard or standard plasterboard ??


and what size ??

[Londondecca]

I used standard 12.5mm plasterboard. I understand the acoustic boards are slightly better but they are more expensive so it will depend on your budget.

However dont let this sound like normal plasterboard is somehow poor or less than satisfactory, it is a perfectly good product. From memory there are some tests on the Green Glue site which compare the normal stuff with the expensive boards and the differences are not huge

[Ted White]

With respect to plasterboard, go with the mass. Whatever's heavier.
