Installing attic insulation is an excellent way to save money on your heating and cooling bills. Insulating your attic will also improve indoor air quality and comfort as well as mitigate noise pollution. Many of today’s materials are also environmentally friendly.
However, attic insulation cost varies depending on job complexity, attic size, insulation material/type, and thermal efficiency. Some materials are more effective than others and, therefore, may be more expensive to install. These materials may, however, offer more substantial savings over the long run.
You are strongly encouraged to discuss all available options with a licensed insulation contractor. The contractor will take precise measurements of your attic, advise you on which options are best for your unique application, and provide you with an accurate attic insulation cost quote.
Attic Insulation Cost & Types
The following insulation types are ideal for unfinished attic walls and floors. Loose-fill and spray foam insulation can be applied to ceilings, open wall cavities, and other hard-to-reach places and require professional installation.
Blanket Insulation: Batt and roll insulation fall under the category of “blanket.” This type can be made from fiberglass, cellulose, or mineral wool. Batts and rolls are available in standard widths to ensure a tight fit between studs, rafters, and joists. Blanket insulation is one of the most economical options.
Loose Fill Insulation: Loose-fill insulation consists of small particles of fiberglass, cellulose, or mineral materials that are blown-in to your attic using specialized equipment. Each of these materials includes a specific percentage of recycled content. Loose-fill can conform to any space.
Spray Foam Insulation: Priced on the higher end is spray foam insulation. SPF typically offers a much higher R-Value than other forms of insulation and can be sprayed into attic walls, floors, or rafters to insulate and reduce air leakage. Spray foam insulation is available in open- or closed-cell foam. Talk to an expert about the pros and cons of each.
How Much Do I Need?
Ideally, you should inspect the condition of any existing insulation, which is something you can either do yourself or hire a professional. Having an energy audit conducted is an even better idea. An inspection can help you pinpoint sources of air loss – sealing air leaks is as essential as improving insulation – and provide a list of efficiency improvements. Discounted energy audits may be available through your utility provider. Just some of the things a professional will look for include adequate ventilation, damp or moldy materials, and air leakage.
What’s in an R-Value?
R-Value denotes the resistance to heat flow through a certain thickness of the material. Higher R-Values generally perform better and, ultimately, provide more substantial benefits. The U.S. Department of Energy provides R-Value recommendations for various climate zones and areas of the home.
