Improve the comfort of your home and reduce energy costs with proper insulation

Did you know insulation plays an important role in how your home uses energy? It's also one of the main players in heating and cooling costs. In fact, the Environmental Protection Agency estimates homeowners can save an average of 15% on heating and cooling costs by air sealing their homes and adding insulation to attics, floors above crawl spaces and accessible basement rim joists (Energy Star).

Most people associate insulation with fuzzy rolls of pink stuff and a recognizable cartoon character, but what is it?

Insulation is a classification of materials that are used to reduce heat transfer from the inside and outside of a building. Most commonly, insulation is used in attics, ceilings, walls, floors and crawl spaces to help maintain more constant, comfortable temperatures in your home. 

Types of insulation

Batts (or rolls) are the most common and available form of insulation, and are often referred to as blanket insulation.

Benefits: Flexible fiberglass batts are manufactured in the right size to fit between wall joists, studs and under floors, and can be easily cut by hand and installed.

Foam board and rigid foam insulation sheets are available in various lengths, widths and densities, and can be used almost anywhere in your home.

Benefits: Can perform up to two times greater than other insulation types with the same thickness and can be purchased at your local home improvement store.

Loose fill or blow-in is made of small particles of different materials that can be blown into areas.

Benefits: Can be blown into areas that may be hard to reach or where it is difficult to apply other types of insulation. Commonly used materials for loose-fill or blow-in are:

               Cellulose: recycled newsprint.

               Fiberglass: comprises 40%-60% recycled glass

               Mineral wool: 75% post-industrial recycled content

Spray foam insulation is a liquid mixture that can be sprayed, injected or poured into place to insulate and reduce air leakage.

Benefits: Conforms to the space where it is applied and is very effective at sealing small cavities and cracks. Some types can have a higher R-value than traditional batt and roll insulation.


Air Sealing

Along with insulation, air sealing is another important and cost-effective way to increase comfort throughout your home. Air leakage and improperly installed insulation can waste 20% or more of the energy used to heat or cool a home (Energy Star). Properly sealing the gaps and cracks in your home will:

  • Reduce indoor pollutants and control moisture.
  • Mitigate air leakage through gaps and cracks found in your home. 
  • Help your heating and cooling equipment work more efficiently.
