All,

I just got off the phone with a local SPI in Chicago area. They quoted me to following prices:

3" OC 703 (Plain) - $1.50/sqft
3" Roxul Rockwool - $0.95/sqft

I thought these prices were really high compared to what I have been reading here. What do you guys think? Can anyone give me a better place to get the insulation from in the Chicago area?

Do I really need 3" or is 2" good enough?

I would say if you're putting it in the walls, go for the mineral fiber (Roxul).

If you're using it for absorbers and covering it in cloth, go w/ the 703, it's more rigid.

The last bag of Roxul I bought (3" x 16" x 48") (64 square feet coverage) I paid about $17 a bag. The average is about $20 a bag. My supplier is giving me a good price.

Yes, this is for inside the walls.

Even at $20 per bag, it's about $0.31/sqft. I was quoted $0.95/sqft! Either they are trying to rip me off or the guy didn't know what he was talking about.

Call Roxul directly and see if you can find another distributor locally...

800-265-6878


Also, I was getting it for .24 a square foot until about a month ago.

OK, I called Roxul, they found only one distributor in the entire Chicagoland area. Called the number they gave me and guess what? The guy on the other end answered "Hello, this is McDonald's ..."

I'll call them again and see if the lady gave me the wrong number, I did verify the number twice though... I can't believe there is no one else that carries their products in my area.

Hmm I have a buddy n chi-town that bought the stuff. I am checking with hinm so i'll be back. with his info.

he had to go to a Company in indy for it. He listed/posted their info in the building products section.

Thanks! I will check it out.

Companies with similar products:

Thermafiber
Fibrex
something like "American Rockwool"

OK, I finally found a distributor that carries Roxul in Chicago. Here is the info, their prices are very reasonable too.

A&I Supply
630-629-3009

They quoted me $20.29 for a bundle (64 sqft). (3" 3PCF stuff, 16" wide)

Resilient channel is available at Home Depot in Bartlett area (Don't have their phone # but do a search at their site)

Now the search begins for acoustic caulk, window glass and wall plates I think I have an idea where to get these, I'll post a list in the products section for everyone in Chi Town

Thanks all for your help, this forum is awesome!!

Did you ask A&I if they carried acoustical sealant? If they don't, try your local supply houses for drywall (and I don't mean HD or Lowes).

Cool! A&I carries the caulk, I had to ask for "Sound Caulk", they did'nt understand "Acoustic Caulk". It's $4.28/29oz tube.

Anyway, the construction on my studio starts next week. I had to hire a new contractor, the other guy never showed up.

All I need to decide now is the CR window, I might have to built one myself.

See if they'll give you a price break by buying it by the case. (usually 12 tubes per case).

You'll go through several cases by the time your done. I've already gone through 4 cases of the stuff, and nowhere close to finished...

Doh!! are you serious! My contractor said three to four tubes, but I was planning to buy 10

I'll see what they can offer, I might start with two cases. I need to caulk at the top and bottom of drywall and room corners right? What else needs caulking?

Every crack between every layer. All corners, bottom of drywall at floor, top at ceiling, windows, doors, etc.

If you're doing multiple layers of drywall, you want to caulk each layer before doing the next.
