Cutting InsulationPlay | Download (Right Click, Save As...)
Adding insulation is a very do-it-yourself friendly project that pays big dividends, so it just makes sense to take on the task yourself. If you do, remember these tips, and you’ll save a few hassles.
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″ to 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 you need to wear a long sleeved shirt, pants, gloves, dust mask, and safety glasses.
