Spray Foam Genie Charleston – How to Insulate Your Attic
blog
The attic is the perfect place to add insulation and improve a home’s energy efficiency. Insulating the attic and reducing air leaks helps save on heating and cooling costs.
Home insulation insulated attics prevent heat loss and keep rooms warmer in winter and cooler in summer, saving homeowners a lot of money over time. But it’s not an easy job, so a professional is usually the best option if you want to get your attic properly insulated.
Before insulating the attic, it’s important to identify any areas where the attic space connects with heated rooms below such as recessed light fixtures, chimney chases, plumbing stacks, and holes drilled for wiring. These are common sources of air leakage. Seal them well before insulating.
The Benefits of Spray Foam Insulation for Charleston Attics
Some attics need to be cleaned before insulating, as accumulated dust can reduce the R-value of the insulation. If that’s the case in your attic, vacuum or sweep it clean before proceeding.
If you plan to use blown-in insulation (also known as loose-fill) in your attic, it’s a good idea to have a friend help you load the equipment and be in the attic with you. Loose-fill insulation consists of bags of cellulose, fiberglass, mineral wool or rockwool that are blown in with special equipment into the attic space and can reach difficult places. It also has one of the highest R-values of all insulation options, but it tends to settle over time, lowering its installed R-value.
If your attic has no chimneys, stacks or other structural features, you can save money and avoid the inconvenience of having to lug heavy insulation rolls into the attic by using a polyethylene vapor barrier directly over the joists. This method requires less stapling and caulking than other methods, and it leaves existing insulation in place.
