1 put on work gloves safety glasses and a dust mask before entering the attic. You can even peel off the paper face it s not a pretty job but it ll work and then lay those batts back down as unfaced.
My attic used to have blown in insulation with plywood sheets and planks here and there for access and storing junk atop 2×4 ceiling joists holding up a plaster and lathe ceiling.
Install attic floor over blown insulation. Laying foil on top of insulation on the attic floor this is probably the easiest method to install radiant barrier atticfoil is to lay the foil out over the existing insulation on the attic floor. To install blown in insulation in existing walls holes are drilled at the top of each stud space usually on the exterior and material is blown in. Build up the height of the joists prior to installing flooring when the insulation reaches the tops of the joists.
Lay the batts perpendicular to the joists so they do not compress the insulation below. Then you ll be good to go. Make sure you use an unfaced batt one without a paper or foil layer so the insulation does not trap moisture in the ceiling.
Insulation should be rolled out perpendicular to the joists and unfaced rolls should be used. It s possible that there s wiring running under the insulation and over the joists so you need to watch out for that as well. Any existing batt or roll insulation in the attic should have the facing against the attic drywall floor or no facing at all.
Batt or rolled insulation or blown loose fill insulation fiberglass or cellulose can be installed on top of old insulation. This method can be used in any climate though it historically has been most popular in colder climates. Wear a long sleeve shirt gloves eye protection and a dust mask.
If blown in insulation is used control the height or thickness of the layers so boards can by laid over top without having to compact the filler. This means of insulation has its disadvantages. Place flooring over insulation to make your attic space functional.
Attics are generally covered in batting or blown insulation. Connect the hose to the blown in insulation machine. You can install fiberglass batts yourself right over existing insulation but follow these precautions.
It was like that for decades. Connect the hose to the insulation machine. You need about 22 inches of blown in or about 19 inches of unfaced insulation in that attic space to give you the maximum amount of warmth.
Then feed 1 2 a bag of fill into the machine and turn on the hose to start blowing the insulation.
