I want my basement (suit) bedroom to be really soundproof. Right now it has only false ceiling of foam tiles. What are my options and what would be the cost associated with that?

Thank you in advance.

You have to use sound proof insulation . For cost it depend on the size. You could also try to get a cost estimate sheet with a materials list from an experienced Rep at a local building centre. They'll list everything and ask the right questions so you'll have a much clearer picture of how much it'll cost you.

When you've got a materials list, you might want to price this stuff out online at Home Depot.

BTW if you're intending to use fibreglass insulation as a sound proofing material, I'd highly recommend you look at Roxul insulation. It doesn't have a high insulation value (R14) but it is very, very dense and works extremely well.

Thank you Chad for the response.

The Bedroom is around 10 by 17 feet and I am kind of interested in roxul because of the online reviews and articles about it.

Thank you so much and I will go to the HD to get the approx quote.

No problem, each bag should cover around 59.8 sq ft. So u will need 3 bags.

Hope this helps.

I would first start with resilient sound channeling, the green insulation soundboard then use two layers of drywall plus the insulation in the joist space. That will do a good job.

ROXUL SAFE'n'SOUND' is a stone wool insulation product for use in interior wall partitions of residential wood and steel stud construction where superior fire resistance and acoustical performance are required. This non-combustible, lightweight product has excellent acoustical dampening properties and it is dimensionally stable which makes it ideal for friction fit into walls, ceiling and floor applications. The product is chemically inert, therefore it will not promote corrosion.

Remove the foam tiles and install the Roxul in between the floor joists and cover with a vapour barrier using 6 mil poly. The material cost is roughly $2.00 sqft if you use two layers of R23 Roxul to fill the cavity. If you double the material price that will give you a rough price for labour and material, so $4.00 sqft.

There are many option for sound proofing a room. It comes down to how well you want the room sound proofed and how much you want to spend.

Good System:

1 Insulated ceiling joists, and wall stud cavities around the room with a Roxul

2. Drywall Ceiling 1/2, 1 coat tape and mud

3. Sound Bars

4. 2nd layer drywall 1/2

If you have hardwood on floor above, consider changing to carpet with good underlay.

Good Luck
