Cutting Insulation

Attics and Basements, Heating and Cooling, Insulation, Interior, Video by Danny Lipford

To cut insulation squarely and accurately use a utility knife with snap off blade. Extend the blade all the way out and lock it. The resulting 3″-4″ blade will make it easier to cut through thick batts of insulation. Use the straight edge of a piece of wood, lay it across the insulation, then kneel on one end of the insulation to compress it and run the blade down the edge of the wood for a nice square cut. Remember, to keep the fibers from irritating your skin wear a long sleeved shirt, pants, gloves, dust mask and safety glasses.

    cutting fiberglass insulation is easy but
    it can be uncomfortable due to the small
    glass fibers i would use corn starch before
    laying it out on the floor.
