How Green Is Denim Insulation?

Yesterday, I wrote about the green merits of cellulose insulation, and today I’ll uncover the benefits of recycled denim insulation. It comes in easy-to-handle batts sized to fit snugly into the framing of standard walls and ceilings.
Denim insulation batts have extremely effective sound absorption and thermal performance. The R-value is 3.4-3.7 per inch. In 2×4 framing, it rates R-13. In 2×6 framing, a R-19 value is present. It gives a better performance than fiberglass at low temperatures and windy conditions.
Made up of 90% recycled natural denim and cotton fibers, denim insulation is also 100% recyclable. 10% consists of a boron-based fire retardant which impedes growth of fungus, mold, and resists pests. Boron is a low-toxic, naturally-occurring mineral that is mined in the deserts of California and elsewhere. The remaining 5% is polyolefin fibers that are used as the glue that holds the batts together.
It takes less energy to manufacture than other types of traditional insulation, contains no chemical irritants, and is easy to install by homeowners.

I have the same questions as Chris can we find denim insulation in Canada. We are preparing to build a totally green home in northern BC and are looking for great products. We are also wanting our house to look like it has been on our property for a hundred years and are having a hard time finding recycled moldings and fittings and such and are now starting to look at new do you have any sugggestions.
You can find Bonded Logic’s Ultra Touch denim insulation distributors in Canada through this company: http://www.twinmaplemarketing.com/ultratouch/
My daughter and her friend are working on a Science Fair Project (Friendly Environmental Insulation vs Non-Friendly) and we are searching for this type of insulation here in Sudbury, Ontario. Is it available in Canada?
