Study: Most U.S. Homes Are Not Properly Insulated
Does your home feel extra drafty and cold in the winter and uncomfortably warm in the summer? It’s likely your home is not properly insulated.
You’re not alone. According to a 2015 study by the North American Insulation Manufacturers Association (NAIMA), roughly 90 percent of homes in the United States were under-insulated, wasting energy and money, and decreasing comfort for homeowners.
- It increases your comfort. Insulation is like a snug blanket around your home. It creates a barrier that slows down the flow of warm air, keeping the heat out of your air-conditioned home during the hot summer months and preventing it from escaping in the cold of winter. With proper insulation installed by a professional insulation contractor, you’ll enjoy a much more stable temperature in your living spaces.
- It protects against ice dams. Poor insulation is a leading cause of ice dams on your roof in the winter. When your attic is not properly insulated, heat from your home escapes to the roof, where it melts any standing snow or ice. That melted water then runs down your roof and refreezes at the eaves, forming ice dams. The dams can prevent water from draining off your roof, so instead, it will back up under the shingles or behind fascia boards, and eventually soak through to your attic, ceilings, and walls. By ensuring proper insulation and ventilation, you will run less risk of the formation of ice dams, substantially reducing the likelihood of water damage to your home.
- It can lower your energy bills. Installing home insulation is also like putting money in the bank, because it can actually put more money in your bank account by slashing the cost of your energy bills. By slowing down the movement of warm air, either in or out of your home, quality home insulation makes your entire home more energy efficient. Your heating and cooling systems won’t have to work as hard, and the cost of maintaining the temperature in your home will drop.
- It’s green. Because it can decrease your energy consumption, home insulation is eco-friendly. Researchers say that if all U.S. homes were fitted with proper insulation based on International Energy Conservation Code, we could decrease electricity and natural gas use nationwide—and cut down on harmful emissions and pollutants in the process.
Where To Insulate In A Home
If you want the best energy efficiency possible, your home should be sealed with insulation from the roof down to its foundation. Our team of professional home insulation contractors can insulate nearly every corner of your home, including:
Types Of Insulation

J&J Roofing is a professional home insulation contractor. We offer three common types of blown-in insulation products: spray foam, fiberglass, and cellulose.
Choosing the best type of insulation for your home depends on where you need to install it, as well as the recommended R-values for areas you want to insulate. R-values measure an insulating material’s ability to resist heat flow—the higher the R-value, the higher the insulating power. Our team will utilize 30-plus years of experience to help you find the best insulation solution for your home’s unique needs.
Polyurethane spray foam is a popular method of insulation with a broad range of applications; it’s used everywhere, from the inside of refrigerators to attic crawl spaces. Compared to other types of home insulation, spray foam is especially good at getting into hard to reach places, making it ideal for walls, crawl spaces, rim/band joists, cantilevered floors, and ceilings.
There are two primary types of polyurethane spray foams:
- Closed cell: The denser and more common of the two polyurethane spray foams, closed cell spray foam is ideal for preventing drafts and keeping in regulated temperatures. It has a superior R-value compared to other types of insulation, and because it is so dense and strong, closed cell foam can strengthen walls and provide water resistance.
- Open cell: Open cell polyurethane spray foam is less commonly used by insulation contractors because it was originally manufactured by only one company, and its R-value isn’t as high as that of a closed cell spray. However, it is often used for its strength, density, and affordability compared to other spray foams.
Fiberglass insulation is a man-made material composed of recycled glass fibers. It’s the most common type of residential insulation available on the market and also the most cost-effective. Besides being a great, affordable insulator, fiberglass insulation has many added benefits. It is fire and water resistant, it will not settle or lose R-value over time, and it’s a very sustainable material. Fiberglass insulation also absorbs sound waves, so your home will be not only more comfortable and energy efficient, but also more soundproof.
Cellulose is the oldest form of home insulation and a great alternative for clients who prefer not to use fiberglass. Typically made from recycled newspapers, cellulose insulation offers a slightly higher R-value than fiberglass, and is easier to install. Another benefit of cellulose is that it retains its insulating value no matter the temperature.
Each of these types of home insulation options will effectively insulate your home, and each has its own pros and cons. Our expert team at J&J Roofing is here to help you make an informed decision about your home insulation. Contact us today to get started!
