I used Roxul to insulate a small cabin. It was the first time I used Roxul and I was amazed at how easy it was to use. Cuts with minimal effort and it fits like a glove. The real test was when we arrived mid February to - 15 Celcius and our cabin took no time to warm up and stay warm.

COMFORBATT R24 16", installed under floor at a cottage sitting on pylons. One man job, the blocks fit the space between joists to perfection -16 centre in this case- when framing is done to code.

Excellent product, I would always choose to use

Would Recommend

This product was great to fully insulate my husband's outdoor cookhouse for fall and winter use. The cedar cabin was not fully water tight but is now and if this material gets a bit wet it doesn't affect it.
