Johns Manville R20 Fibreglass Batt Insulation 120.11-Sq. Ft. Attics and Floors is rated 4.8 out of 5 by 6.
Rated 5 out of 5 by from John Manville insulation vs Dow Corning. I found the John Manville insulation net superior to the Dow Corning one. First, the fiber is much thinner leading to much smaller pores in the bat and better insulation due to constricted movement of the air. Second, being finer, the affection on the skin is incomparable less. Third, is not combustible, unlike Dow Corning. It shrinks but does not combust in fire. Fourth, is heavier and more compact than the regular Dow Corning fibre glass boards, rivaling their double weight compacted fiberglass boards.

Rated 5 out of 5 by from insulation for attic The insulation is to finish the attic. No issues with the product.

Rated 5 out of 5 by from Great insulation. Good insulation for garage walls and/or attic space. After insulating I noticed the difference the next day, temperature outside was 30+, but inside it didn't go above 20-22 Celsius. Will see how it performs in winter.
