Who sells mineral wool board near Boston?

I was just told by a large north-of-Boston lumberyard that stocks Roxul products that they can't get any of the Comfortboard IS products in less than half-truckload amounts.

Who is stocking this stuff near Boston? I am hoping to use mineral wool instead of foam on a project this spring, but I'll need 200 sheets max, not 1000.

I had the same problem in the Green Bay, WI area until I walked into a Home Depot (which I usually won't do). They looked up the Comfortboard IS for me and said "how much you need?" I'm going with two 3" layers on a 1,200 sq. Ft. house and they had no problem. Not sure if that is a half truck load or not. It's now made in MS and they can get it with a 10 day lead time. They had the price to me in two days. I was impressed.

Paul,

Interesting. Here in the Denver area, you still can't easily get ComfortBoard IS. PrimeSource (North American Distributor) sells it via Home Depot (you go through the pro desk) but getting pricing is tough. You don't have to order a full truck but you'll need to wait until you complete a truckload. FYI, a truckload of 3" board is ~13000 sf. It's taken me a few tries to break through the 'we don't sell it. oh we do but you need to order a full truck. oh we do and can work with smaller quantities but on our schedule'.

Good luck Eric. I'm guessing it's easier near the board

I had exactly the same problem so I ended up ordering from Roxul Rockboard 80 from ATS Acoustics http://www.atsacoustics.com/ because they could get me the product in about 4 days. Yes, shipping was very expensive. I did get a volume discount for the amount I ordered. I don't know if it would apply to the amount you are ordering.

I have been assured that the density of Roxul Rockboard 80 is same density so it sounds like it is essentially same product. See the links below:

Eric, you could consider switching to wood fiberboard insulation. This product is a WRB and insulation in one, with T&G edges. It is also very vapor open so just like mineral wool let's walls breath outwards in NE winter. We sell it by the pallet or board on 475 - see GUTEX Multitherm. Currently in stock in 1-9/16" thicknesses.

So I found retailer, Sterling, in Waltham, MA. Sounds promising, knows the product, can get whatever quantity I need and the price is reasonable too. If you are in the Boston area check them out at http://sterlingbm.com/

Gutex looks interesting, How do you install siding over it? Can rain screen battens or siding be fastened directly to it, or must they penetrate the studs?

The cost looks pretty prohibitive, $1055 for 18 boards that cover 486 sq. ft.....

Eric, since the board is insulation, albeit a dense one - it doesn't hold screws (nor does mineral wool). so indeed you would want to hit studs or other load bearing elements.

Per board foot it is about $1.40 - when you factor in the savings of not having to install a WRB (cost + labor). the difference with mineral wool shrinks.
