Adding Blown-in Fiberglass Insulation

Increasing the R-value of your attic insulationLess dusty than cellulose, blown-in fiberglass increases R-value and installs quickly.

Watch Fine Homebuilding contributing editor Mike Guertin increase the R-value in an attic from R-15 to R-40 with blown-in fiberglass insulation. Mike uses Owens Corning’s AttiCat system to add approximately 9 in. of insulation between the attic ceiling joists. This short video includes tips on everything from safety gear to achieving an even distribution of fiberglass throughout the space.

To learn how Mike further sealed his attic, read Attic Insulation Upgrade.

    I'll take your money instead
    Loose fill blown in fiberglass is a waste of time/money in most northern heating climates. It looses R value as temperatures drop. It is not dense enough to impede air flow. So instead of wasting your money blowing fiberglass in your attic, send your money to me I will spend it on something much more fun like a new sportscar. You can live vicariously though me and I'll even send you pics.
