How Do You Install A Floor Over Attic Insulation?
Laying a floor over insulation isn’t that much different than laying one over a non-insulated floor. Many attics have multiple layers of rolled insulation or mounds or snow-like blown-in fiberglass covering the joists where the floor will be put down. It is necessary to remove excess and level out the insulation to make room for the boards to lay flat to the joists. Insulation is both dangerous to breathe for long periods and irritating when contacting bare skin, so proper care must be taken. Remove any added rolled insulation laying perpendicular over the joists. Lay a few pieces of flooring down over the joists as a work platform and to protect you from stepping through the ceiling below. Ensure the insulation is flat and doesn’t extend over the top of the floor joists. For paper-backed, rolled insulation, lightly pack it down as flat as possible below the edge of the joists. For blown-in insulation, use a long board to even it out by dragging it over the joists to push insulation fl
