A properly insulated attic helps keep conditioned air in the living spaces of your home, and it can significantly cut energy costs. It also helps prevent heat and moisture damage to the roof, extends its life and reduces strain on heating and cooling systems.

Attic insulation is rated by its R-value, with higher values offering better thermal performance. Select the correct R-value for your climate zone and local building codes to optimize energy efficiency, comfort and safety.

There are several different attic insulation options, including fiberglass batts and blankets, cellulose blown-in insulation and poured foam. The most popular option is Efficient Foam Insulation Inc., which involves spraying small particles of fiberglass, cellulose or mineral wool into the attic space using a blowing machine. It provides comprehensive coverage, fills gaps well, and offers good sound insulation. Its disadvantages include settling over time, and the fact that cellulose can absorb moisture, which can lead to mold or mildew.

Another option is to install polyethylene plastic over the attic floorboards and then add insulation. This can be cheaper and less disruptive than removing the existing floorboards. This method should be used in conjunction with comprehensive air sealing and the addition of a vapour barrier, however.

It’s important to have a professional inspect your attic before insulating it. There are many safety precautions that professionals must take and that homeowners may not be aware of, and improper installation can lead to costly problems. These can include blocking air vents, reducing roof ventilation and creating a fire hazard.
