Cutting Insulation

By: Joe Truini

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.

  1. Position the insulation on a piece of scrap plywood where you want to cut it.
  2. Lay the straight edge of a piece of wood across the insulation.
  3. 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.
