Attic Insulation: What you should know

Our region has experienced the coldest winter in years. (No thanks to that famous groundhog prediction!) Plus, our friends to the northeast have been shoveling more snow than ever. We think NOW is a great time to talk about the comfort and savings possible with proper attic insulation.

In fact, one of the best ways to improve the energy efficiency of your home and reduce utility bills is to keep your attic properly insulated. If your home is relatively new, the insulation is most likely sufficient, but if you own an older home, you should inspect your insulation level to see if it needs to be improved.

Generally, if you can see the top of the floor joists, the insulation layer is NOT thick enough. A thick layer of insulation has a higher “R-Value” – which simply means resistance to heat flow (loss). Insulation products with higher R-Values are more energy efficient. If you decide to upgrade your insulation here are some of the common forms available:

Batts and Blankets

The most common form of insulation is made from FIBERGLASS and comes in blanket rolls or batts. It comes in different thicknesses and widths to match the stud or joist spacing in your home. It can be difficult to handle and can compress when being installed which lowers it’s R-Value. It is best to call a knowledgeable contractor, such as ServiceMark Heating Cooling & Plumbing, to not only advise you on what type and how much insulation is required to make your home more energy efficient, but ensure proper installation, too!

Loose-Fill Insulation

Loose-fill insulation is made from CELLULOSE, ROCK WOOL, or FIBERGLASS, and is also known as blown-in insulation. With this method, a machine is used to blow small bits of the insulation material over an entire area. As the material is discharged, it puffs up and sticks together to form a thick layer of insulation. The biggest advantage to employing the loose-fill insulation is that it can cover hard to reach spaces in the attic. This approach is commonly used by ServiceMark Heating Cooling and Plumbing. Although this type costs a little more to install than batt-and-blanket insulation, it does a better job at saving energy and reducing monthly utility costs – saving you more in the long run.

Spray Foam

Spray Foam is the newest form of insulation available, and is also more expensive than other types. However, it does make your home extremely energy efficient! The POLYURETHANE foam is sprayed all over the attic ceiling and as it dries it expands to form a thick layer of insulation. When done by an insured, trained and bonded contractor, such as ServiceMark Heating Cooling & Plumbing, it can actually form an air tight barrier. This is the proper choice, especially when planning to make the attic room an additional living space.
