When a home's rafters need to be insulated or require additional insulation in order to meet the U.S. Department of Energy's recommendations for R values, fiberglass blankets are a popular choice. This material is commonly found in homes across the country due to its affordable price and ease of installation. The insulation comes in two different widths, which are sized to fit between standard roofing joists, and it can be unfaced or come equipped with kraft paper. Once local Essex County roofers have installed the insulation, homeowners can enjoy lower energy costs and a better performing roof.

To lay the rolled fiberglass insulation, roofers will don gloves and safety glasses, as loose fibers of the material are an irritant to the respiratory system and skin. The crew will start working at one corner of the attic. If the attic doesn't have a floor, they will walk along the joists or perhaps lay temporary boards to walk on. If there is already some insulation present, the roofers will select fiberglass with no backing. If the old insulation has been removed or there was no rafter insulation, then fiberglass rolls backed with kraft paper will be the material of choice.

The roofers will unroll one of the bundles of insulation and spread it out so that its edges run parallel and snug with the edges of the rafters.

Once one of the rolls runs out, the roofers will start a new one. Butted seams will be created between two separate pieces so that no air exchange can take place. These tight seams between individual sections of insulation are also necessary in order for the insulation to perform effectively.

If a roll is too long, the roofers will trim it to size with a utility knife. The material will also be trimmed so that it does not overlap any vent openings or electrical fixtures. To keep the insulation in place, the crew simply pushes it in with their hands. No nails, screws or adhesives are needed for this project.

Fiberglass insulation must be kept away from sources of heat within the attic, as the material cannot withstand temperatures in excess of 212 degrees Fahrenheit. Roofers need to keep the insulation at least 12 inches away from any wood stove, furnace flues or chimneys. A different material, such as sprayed foam insulation, can be used to insulate and seal up spaces closer to heat sources. If there is leftover fiberglass, it can be spread across the attic floor to help insulate the home's ceilings.
