New Build. At basement level.

unclebill98

Hi all.

1st post regarding my new build. I've done tons of searches here about lots of things from ground work to Basement Tanking. So thanks for the help.

It brings me onto a few things that are kind of specific to my build.

The house is a Dormer Bungalow with a basement. Its standing at 5k square feet at the moment.

The basement is going to be used as a Recording Studio. I have the ceilings at 10 feet. I am looking to insulate them to avoid as much sound spilling into the living areas of the house. I can easily drop the ceiling by a foot to leave the space to be filed my the insulation and still be left with 9 ft ceilings. What sort of insulation should i be thinking of? Is there a combo of insulation that will work?

Also, I need to have windows installed between rooms as to see clients etc. Is there any company that can design such windows for this use? Someone had mention just putting 2 double glazed windows and that'll do. I am sure there is a better option than that.

Is it safe to leave a gap between the rooms, say one block as to feed cables between rooms?


Thanks in advance for any help/feedback.

I am pretty sure I'll have more questions..... A house built with the help of boards.ie!!!

As you probably already know sound proofing a ceiling is a very difficult thing to do but it can be done. what you need for this is two 12.5mm plasterboards or even bigger, 100mm insulation, acoustic membrane and resillient bar which is super for sound proofing in ceilings.

There are two ways of doing this
a) You can strip out existing ceiling. and fill the cavity space with 100mm acoustic insulation, then fix the resillient bar perpendicular to your ceiling joists at 400mm centres, Fix the 1st plasterboard screwed to the resillient bar and then stick a layer of the acoustic membrane to plasterboard, when this is done fix your 2nd plasterboard to the ceiling.
Make sure to keep the plasteboard 5mm away from the perimeter walls and fill the gaps then with loads of acoustic sealant in order to seal the gap airtight to allow the floating in your new system.
i feel this is a very good way of doing the soundproofing.

b) You can also work from existing ceiling and batten it out with 50mm * 50mm battens perpendicular to other battens via 5mm neoprene isolation strips then between the studs fill with 100mm acoustic insulation and then follow the same steps as above.

You can also improve the job too by stapling acoustic membrane to your battens/studs before you fit resillient bar and then put another layer of membrane between plasterboards.

And in relation to your studios with glass between them i feel that two layers of 10mm laminated glass would be a good product to use and it is good for sound proofing too.

I hope all this information is of good help to you and if you require any more help dont hesitate to ask as i specialise in the area of dry lining

Read the OP again, there is not existing ceiling. Its a new build house that is yet to be built.



UncleBill, I have to head now, but i'll stick up a decent reply later. By the way, I have removed the section of woodpellets. They belong on the DIY forum. Feel free to repost them there. Forum rules.

Hi Uncle

I don't think you find a better guide than this

http://www.bbc.co.uk/rd/pubs/archive/pdffiles/architectural-acoustics/bbc_guideacousticpractice.pdf

look around pages 73- 78 for details on vision panels and internal doors . Also how to detail around vents into the studio .

For sound separation to above you really need to be thinking concrete floor overhead .

IF you need to improve the Internal sound quality of the studio by installing wall mounted box / drums REMEMBER - they must be fire resistant . Use Class O medite and fire resistant fabrics over

And think about your internal planning - you wont want your washer dryer rumbling in a utility overhead

I wrote this the other night, but forget to post it.

pretty big project you have there, is it self build. Who else is involved, (architect, engineer, QS, contractor etc)

Firstly a concrete flor will do alot, possibly a solid precast floor over a hollowcore precast floor. After that, i'd be looking at (semi)profesional acoustic linings.

Also, I need to have windows installed between rooms as to see clients etc. Is there any company that can design such windows for this use? Someone had mention just putting 2 double glazed windows and that'll do. I am sure there is a better option than that.

Why two double glazed units? And not one? Do they need to be sound proof?
This windows would be quite simple and any joinery would be able do it.

Is it safe to leave a gap between the rooms, say one block as to feed cables between rooms?

Is it safe, yes. Practical, i'm not sure. There are likely to be better options. Service cavites etc, where it would be possible for access if needed

I am pretty sure I'll have more questions..... A house built with the help of boards.ie!!!

It probably isn't the first
