Insulation is a spray foam insulation part of the home’s energy envelope and if installed correctly can cut utility bills and make the house cozier all year round. But do-it-yourselfers and even professional contractors often overlook the attic, which is a major source of energy loss. Avoid these six common attic insulation mistakes and your home will be warmer, more comfortable and more efficient.
Not Sealing around Penetrations
Many homeowners forget to caulk the penetrations where pipes, wires and ductwork enter into the attic. This can allow warm air to leak into the attic and down through the living spaces, reducing your energy efficiency.
Using the Wrong Insulation
Not all types of insulation are suitable for attics. Some materials, like affordable cellulose, can trap moisture and create a breeding ground for mold. For attic insulation, it’s best to use a more durable material such as spray foam.
Squishy Insulation
A common mistake is installing insulation too tightly, compressing its air pockets and lowering its R-value. It’s important to install insulation loosely according to the manufacturer’s specifications to preserve its insulating capabilities.
Pests Love Attics
Rodents, mice and squirrels can easily nest in attic insulation. This can lead to a host of problems, including reduced energy efficiency, an uncomfortable home and potential fire hazards. Be sure to regularly inspect the attic and block or close any entry points that might allow rodents in. Also, ensure that the attic access hatch is properly insulated and weatherstripped to prevent air leakage.
