Brief discussion on the merits of both types of insulation.

Canadian price at home depot is (2x4 walls) Pink=$53.50 for 97.9 Sq Ft and Roxul is $56.69 for 59.7 Sq Ft so that's roughly twice as much cost or 1/2 as much product. The bags are a similar size but Roxul won't compress as much as Fiberglass so the bags have roughly 1/2 as much product inside.
