Is Your Home Insulation Still Working?

Home insulation can last 20 to 80 years. However, it may need to be replaced sooner depending on the type of insulation, the R rating, compression, and movement over time, and whether any damage has occurred.

Here are a few signs your insulation may no longer be working:

  • Lingering unpleasant odors
  • Worsening allergy symptoms
  • Water damage
  • An unanticipated rise in bills
  • Heating and cooling issues
  • Household pests

The Best Ways You Can Improve Your Home's Insulation

Mass Save® offers insulation rebates to residents as part of their energy conservation initiative. The program provides homeowners with 75% to 100% off for insulation improvements, incentivizing energy-efficient enhancements and ultimately leading to substantial savings on utility bills.

  • Use spray foam to add insulation and seal air leaks
  • Use batts or blankets to improve the R-value of your attic
  • Use fiberglass batts and blankets, which are the most common and inexpensive types of insulation, or;
  • Use expanded polystyrene (EPS), which is cost-effective and efficient, or;
  • Use foam board or rigid foam, which provides good thermal resistance and reduces heat conduction through structural elements
  • Seal air leaks with weatherproofing strips and caulking
  • Add thick curtains to your windows
  • Fix drafty doors with a door snake
  • Seal your attic air leaks
  • Plug your chimney when not in use

The most efficient way to insulate a house is to add insulation to the areas that are most vulnerable to heat loss, including the attic, exterior walls, and floors. Attic insulation is the most effective at preventing heat loss, as it prevents heat from escaping through the roof.


The EPA estimates that the average homeowner can save 15% on heating and cooling costs by adding insulation in attics, crawl spaces, and basement rim joists.

The Kinds Of Insulation You Can Get With The Mass Save® Program

Blown-In Cellulose Insulation:

Cellulose insulation is a type of insulation made from recycled paper products, primarily newsprint. It is mechanically blown into or onto empty spaces in the structural part of a house to slow down the transmission of heat or cold.

Cellulose insulation has a very high recycled material content, generally 82% to 85%. It is prone to settling and compression, which can decrease its R-value. It also requires specialized equipment to install, so it's less DIY-friendly than its batt insulation counterparts.

Cellulose insulation has a lifespan that can last up to 30 years. It's a green and effective choice.

Spray Foam Insulation:

Spray foam insulation stands out as an exceptionally efficient insulator and air sealer. Its unique ability to be sprayed into snug cavities, expanding to fill the space makes it perfect for hard-to-reach areas.

Its resistance to moisture accumulation reduces the likelihood of mold or bacterial growth. On the other hand, open-cell spray foam, though less common, expands upon application, making it ideal for difficult-to-access corners.

Although it lacks the water resistance and density of closed-cell foam, it offers a cost-effective alternative, delivering effective insulation at a more economical price. Regardless of the season, if keeps the inside of your home at just the right temperature.

Fiberglass Batting Insulation:

Fiberglass batt insulation is a type of insulation that is made of fiberglass. It is also known as blanket insulation. The manufacturing process uses molten glass spun or blown into fibers. Most manufacturers use up to 40% to 60% recycled glass content. It is one of the most common products used to insulate walls, ceilings and attics as well as basements and crawl spaces.

Rigid Foam Insulation:

Rigid foam insulation is made of hardened foam plastic. It is typically made from one of three types of plastics: polystyrene, polyisocyanurate (polyiso), or polyurethane. It is known for its durability, insulating capabilities, and resistance to water and pests and is often used in crawlspaces and basements.

Rigid foam insulation is applied to the exterior of a building as a continuous layer of insulation and is used to prevent heat loss and gain through the wall frame, floors, and roof.

Why is insulation good for the environment?

Insulation is good for the environment because it reduces the need for natural gas, propane, fuel oil, and electricity to heat and cool buildings. This reduces emissions of pollutants such as carbon dioxide, sulfur oxide and nitrogen oxide.

Insulation also reduces energy consumption and the demand for utilities that rely on fossil fuels to produce power, such as gas, oil, and charcoal. In addition, products like cellulose and mineral wool use recycled materials, which enhance sustainability.

Insulation is one of the most accessible and effective ways to reduce heating and cooling energy use-and, therefore, greenhouse gas emissions-in the built environment.

How does insulation conserve energy?

Insulation conserves energy by reducing the exchange of heat through a surface such as the ceiling or walls. Insulation works by trapping tiny pockets of air to slow down the movement of heat out of the house in the winter and into the house in summer.

Insulation can help you save up to 20% on your home's heating and cooling costs or up to 10% on its total energy costs. Insulation also improves comfort by making your home more pleasant.

Insulation can also benefit the environment by reducing emissions of pollutants such as carbon dioxide, sulfur oxide and nitrogen oxide.

How long does home insulation last?

Home insulation can last 20 to 80 years. However, it may need to be replaced sooner depending on the type of insulation, the R rating, compression and movement over time, and whether any damage has occurred.

Do insulation upgrades really save money?

Yes, insulation upgrades can indeed save you money over time. Proper insulation acts as a barrier to heat flow in your home, reducing the amount of energy required to maintain a comfortable temperature. In colder months, it keeps warm air from escaping, and during warmer months, it prevents hot air from entering your home. This results cutting your heating and cooling costs by an average of 20%!
