Why home insulation is essential

Insulation keeps your home comfortable year-round, no matter the weather. And because the Massachusetts and Rhode Island area experiences weather extremes in both the summer and winter, quality insulation is essential.  The walls and roof of a home are the places that let in the most airflow because of their large surface areas. Therefore, they are the most impacted by heat loss in the winter and heat intrusion in the summer.  Proper insulation keeps your family and pets comfortable and even reduces your energy bills.

What types of home and residential insulation do you use?

Every home is different. Therefore, 5C Energy Inc. offers a variety of insulation types to meet any need. We will customize your residential insulation solutions using these materials:


This is the most common insulation material and the type most people associate with residential insulation. It has a long history and provides exceptional results. Fiberglass is a great option for:

  • Attics
  • Crawl spaces
  • Walls
  • Ceilings

Depending on where it will be placed, our local home insulation technicians can use either rolled or blown-in fiberglass. Blowin-in is usually less expensive, but rolled fiberglass can provide better coverage. We will help you review your options before beginning the insulation process.


This is our most environmentally-friendly option because it is made from recycled materials. So, if you are looking to reduce your carbon footprint, be sure to ask our home and residential insulation experts about cellulose.

Spray Foam

As the name suggests, this type of insulation is sprayed on. It goes on wet and expands to seal all gaps from air intrusion. Spray foam is an excellent option for hard-to-reach areas or awkward crevices. It even stops moisture from entering your home. Spray foam lasts longer than other options and is very durable. Depending on your needs, our local technicians will use either closed- or open-cell spray foam.

Radiant Barrier Solutions

These include reflective materials placed beneath your home’s roof. They reflect sunlight to keep your home comfortable during the summer months.

Where are the best places to insulate in a home?

Your home should be insulated from the foundation all the way to the rooftop. That said, the following are some areas where insulation is essential.


Unfinished attics allow for unfettered air intrusion. Our team also insulates the attic door access for extra protection.

Exterior Walls

Insulating exterior walls is essential because they have direct contact with the outside elements. Homes in Massachusetts and Rhode Island need exterior wall insulation because of the frigid temperatures that our region experiences in the winter months. In an existing home, blown-in insulation is often a good choice. If you are remodeling we can use spray foam insulation solutions. Our team will let you know which insulation option is best for your exterior walls.


Floor insulation is especially important in areas such as attics. It provides an extra layer of protection from heat loss or air intrusion.

Windows and Doors

Windows and doors are portals to the outside. Therefore, they need to be properly insulated. Caulking and sealing are additional steps taken by our home and residential insulation company.


Placing insulation around ducts keeps energy loss to a minimum and optimizes your utility bills.

These are just some of the areas around the home we insulate. You’ll learn all of the details during your consultation with 5C Energy, Inc.
