    Default Fiberglass vs cellulose

    Can someone please tell which one is better and why?
    I want to put more insulation in my attic and am debating between fiberglass and cellulose. Some people said fiberglass is better while others said cellulose; I am very confused!
    I live in Denver Colorado.

    Default Re: Fiberglass vs cellulose

    I prefer fiberglass properly installed with bats between the joists and another layer running across the joists. Cellulose, while it does do a great job filling voids, settles over time. You can blow in 6" of cellulose and in just a few years it settles and you end up with about " plus it's a nightmare if you ever get a roof leak. By far the best choice would be closed cell foam. It has a greater R value per inch, fills all voids, seals along joists, and is almost structural.
