Putting fiberglass batts in attic.

Lay the batts across the ceiling joists covering the existing insulation. To install fiberglass batts over existing insulation lay the batts perpendicular to the joists so they do not compress the insulation below. Insulation should be rolled out perpendicular to the joists and unfaced rolls should be used. Batts are easier to handle than the type that consists of thousands of tiny chunks.

You may need to make two or three passes to cut all the way through. Air migrates from warmer spaces toward colder spaces and insulation is designed to help prevent or at least slow that migration. Kneel on one end of the straightedge and press down on the opposite end with your hand. Continue laying down the insulation making sure the batts are pressed tightly together at all edge and end joints.

Any existing batt or roll insulation in the attic should have the facing against the attic drywall floor or no facing at all. Measure and cut your own batts from rolls of fiberglass insulation. The best part is the savings comes without compromise and without losing any of the benefits your customers were looking for by requesting spray foam.

Blown in insulation consists of bags of fiberglass or cellulose that are chopped up and blown in to the attic or wall from a machine. Because of this this method will normally require you to hire a professional. Anytime you can decrease the amount of spf and use more fiberglass there will be a cost savings.

Begin laying in the insulation starting at an area farthest from the attic access image 1. When you reach the end of a line pull the insulation back slightly then place it on a joist so there is a solid surface to cut on.
