Any comment?

I live in Canada and bought mine at Home Depot! According to their webpage they sell in many country's. I would assume the HD in the US would likely have it!

Their residential products aren't available in the U.S., just the commercial and industrial.

That's interesting! The US is usually the first place Canadians look to send their products! After using this insulation, I never consider using anything else. Its nice to work with, doesn't give off particles like f/g. It doesn't melt in a fire, so forms a fire barrier. I once seen a demo, where a block of f/g and a block of Roxul were floated in a bucket of water, for a period of time. The f/g sunk quickly, whereas the Roxul was still floating like a cork, the next day! As Home Depot sells this in Canada, I would think that HD in the US would be willing to order it in for you! Is it possible that the national building code doesn't allow this? That's the only reason that I can imagine, that its not sold in the states!

I'm not sure of their reason. Here is the response I got from them in an email:

Quote:
Thank you for your inquiry. With regards to your e-mail, our residential products are not available in the USA - only our commercial and industrial products. The one batt insulation we do offer to the US is Roxul AFB® (Acoustical Fire Batt). This is a commercial product designed for acoustical performance for interior partitions. The sizing of this product is for steel stud which means the batts will be exactly 16" and 24" wide. If you intend to use AFB® for your home in a wood stud application, you may have to cut off a small amount from each batt. AFB® thickness ranges from 1" to 4" in 0.5 increments, then 5", and 6". We do track the R-value of this product, which comes to R 4.1/inch, not 4.3/inch. For example, if you have a 3.5" product, you will have an R-value slightly above R14.
I'm on my way to Home Depot right now, I'm going to ask the store manager if he knows the reason or if he can special-order some. When I asked about it at Lowe's, the employee in the insulation dept. didn't know what I was talking about. He called his boss and he didn't know either. I only know about it from watching Holmes on Homes. They say the same kind of things about it on the show as you said in your post. I'm going to be in Detroit in March and I thought about going over to Windsor to buy some, but I'm not sure they'd let me bring it back into the U.S.

I can't imagine why they would prevent you from bringing it back with you! After all, we do have free trade! I know that there are limits on food stuff, mainly on tropical foods such as oranges and grapefruit. And some kinds of meat! When I used to go to Texas, I was able to look at a website operated by the US government, that listing prohibited goods. If I can find it again, I'll post it here!

daveyd, I think you can also add insulation between the 2x4's after using foamboard on the block walls. As far as whether to use faced or unfaced fiberglass, it probably depends on whether or not the foamboard you put up will qualify as a vapor barrier and how well you seal it between, above and below each piece. I don't think you will have too much insulation, it will just give you a higher R value. Here is a website that gives a lot of information about insulating a basement:

It was a no-go at Home Depot. The guy behind the contractor's desk didn't know what Roxul was. But he said he could try to special order it when I need some. When I told him about the Safe & Sound, he said that fiberglass insulation has some sound deadening qualities . Sound deadening qualities? There is ceiling insulation in the finished half of our basement and insulation in the ceiling of our main floor. Where were those 'sound deadening qualities' when I was working up in the attic, singing quietly, thinking nobody in the basement could hear me? They told me I should stick to singing when I'm alone in the car with the windows up.

Daveyd do you have a Home Builders Association anywhere in your area? The last I knew, the one near me has a sale once or twice a year and they sell all the leftover building materials their members couldn't return to the store. They might have some kind of sound proofing materials from building home theaters or home music studios. Also, contact a few electronics stores and ask to talk to their guy that designs home theaters. He might be able to tell you where to buy or get some.

Found this info, about importing goods into the US! Personal Exemption for U.S. Visitors Returning from Canada: 1. Less than 48 hours stay - You may anytime bring back $200 (U.S.) worth of personal merchandise. Remember, if you exceed the $200 exemption, all your items become dutiable. 2. Over 48 hours stay - Every 30 days you are allowed to bring back free of tax and duty $800.00 (U.S.) worth of personal merchandise. You may include 100 cigars (non-Cuban), 200 cigarettes and 1 litre (34 oz.) of alcoholic beverage as part of your exemption. Articles in excess of the personal exemption up to $1,000 will be assessed a duty. Members of families traveling together are permitted to combine their exemptions. Unsolicited gifts worth up to $50.00 (U.S.) may be sent by mail into the U.S. Hope this helps!

Wow, that's good to know. Thanks for finding that and posting it. Maybe I'll just scoot over into Windsor every time I go to Detroit and buy a little less than $200 worth until I have what I need. I probably won't be able to carry even that much at one time. Thanks again.

Do they keep track of the time and name of every person going over the border?

I imagine that they would! Keep in mind that you will require a passport to get back into the US. Its not required to come to Canada, but you'll need it to get back!
If you bring a friend, then you could bring back $400 worth!

What about using the insulation between the joist and then putting up some 3/4 or 1" foam board. It would give you more sound proofing and keep the insulation in the ceiling and not on your laundry. Wouldn't cost that much more to do, the foam board is pretty cheap

The foam board must be covered by drywall, as its flammable.
