Handling fiberglass insulation does not typically pose any long-term health risks if adequate safety measures are taken. Always wear eye protection, a dust mask, a long-sleeve shirt, long pants and closed shoes when handling insulation. If you suspect that your insulation is not fiberglass, call a professional and have it examined for asbestos before disturbing or removing it. If you suspect you have a mold issue in the insulation due to a leak, likewise consult an expert before attempting to remove any material.
Fiberglass batt insulation is comprised of fiberglass insulation, often pink or yellow in color, glued to a paper backing. This makes rolling and unrolling the insulation significantly easier, and it gives you something to grab the insulation by other than the raw fiberglass. When removing Formica fiberglass batt insulation, take note that the paper backing can dry out and come away from the insulation material. Take your time and rake out any loose pieces that fall away from the batting.
Fiberglass roll insulation does not have the paper backing. When fiberglass rolls are initially installed, they are unrolled and pressed between the beams and studs to insulate the home. Removing old rolls of insulation can be more complicated, however, as fiberglass rolls have a tendency to dry out and become brittle. Take out as much as you can in whole pieces and remove the rest by hand.
Blown insulation is a fiberglass material not adhered to a paper backing or formed into a roll. It is blown in and is preferred by some homeowners for its ability to get in to small spaces where rolls or batts would not fit. Removing blown-in insulation is a messy job, and it will take a considerable amount of time. Use a rake and trash bags, working slowly to minimize the amount of fiberglass you make airborne. Close off the area you are working in to prevent spreading fiberglass dust throughout the home.
