Insulation

[axeman_ukl]

i am moving rooms in my house and have got the front attic 15" x 11" now i want to sound proof this room by puting some insulation into the walls ,now is there any type you should use or is it just a case of going down to b&q and getting 200mm thick insulation in 4meter lenghts,or does it have to be a certain quality ?

Hiya axeman

If you have the ability to strip the walls and replaster, I'd recommend using R2.0 rockwool (the builder I used brought in Bradford batts) between the studs and replastering with soundcheck board (dense plasterboard with good sound baffling properties)
If you're in an attic, you might have trouble with environmental noise coming in from the ceiling as well. If you are able to, I'd suggest packing dense insulation (R3.0 rockwool maybe?) into the ceiling and replastering with soundcheck also.

The other consideration will be any windows in the room letting in noise. Consider double glazing with two different thicknesses of glass to prevent sympathetic vibration between the sheets. If the windows don't need to open
for ventilation, then you'll have more success than I have at stopping noise from coming into the room

While any type of insulation will help (to some degree) remember that it is mass, not bulk, that provides the most soundproofing. The more dense the materal, the better it will work. Insulation will help keep you warm/cool but a double thickness of wall board will do a lot more to stop sound transmission.

Yup, what he said, then, decouple. Can you hear me now?

related insulation question

I work for an online school. We record voiceovers for Flash training movies. Our recording hardware is nothing special (PC not Mac). We just moved to a new space and the room they designated as the "studio" is not ideal. It's about 7' by 10.' It's basically your typical inner office in a typical office building: three drywall walls and one glass wall with a door that opens to the hall way. The glass wall is basically a lattice of metal with large glass tiles. The room dampens sound fairly well. But the glass wall is a major problem. It basically transmits most of the sound that hits it--from both sides. The company is leasing the building so making alterations to the walls/ceiling is not an option. We can add insulation and do anything else.

Any suggestions?

Construct a wall like structure that can actually be in contact with the windows to help damp it's movements. That will make the room sound better if it's absorbtive and also reduce sound transmission. Think of grabbing onto a bell that's ringing.
