Batt Insulation Cost Per Square Foot

Blanket insulation comes in the form of batts or rolls and consists of flexible fibers, commonly known as fiberglass. Fiberglass is the most common insulation material and is constructed of tiny pieces of glass fiber. It comes in low density, medium and high density options.

Blanket insulation is also made with wool, plastic and organic fibers like cotton. Homeowners can purchase batt and roll insulation with or without facing. Facing helps defend against moisture and temperature. Some types of batt insulation also have fire resistant features. The most common R-value for batt and roll insulation is between R-3 and R-4 per inch. Depending on the thickness of your insulation, the R-value can go up to 60.

Roll of Insulation Price

A roll of insulation costs about $0.80 to $1.00 per square foot. The price fluctuates depending on the brand, material, thickness and R-value of the insulation.

Ecobatt Insulation Price

Ecobatt insulation costs about $1.80 per square foot of R-19 grade material. Ecobatt is made of organic materials and is a sustainable insulation option.

Differences Between Batt and Roll Insulation

Homeowners can choose from many types of batt and rolled insulation for residential uses. Keep in mind that roll insulation is available in a roll, whereas batts come in pre cut sections.

• Made to fit in between joists and studs, rolled insulation is available in lengths that range from 20 to 40 feet, making it better suited to insulate areas such as attics, flooring and other spaces with long spans.
• Batt insulation is better suited to fitting right into spaces. It can be a good option on and in walls, floors, ceilings and attics, rafters and trusses within attics.
• Batt insulation may also be covered with paper or aluminum exterior layers, which act as a vapor, air or dual barrier. This type of insulation can also have optional flame retardant coverings for exposed insulation.
• Batt insulation can be used in any unfinished wall, including the foundation. Floors and ceilings can also benefit from batt insulation.
• Thanks to its low price, homeowners can install insulation themselves or hire contractors to install in between joists, beams and studs during new construction or a home renovation.

Where to Use Insulation

Heat typically flows upward and can escape through the roof and attic of a home during colder months, so it is important to insulate these areas well. Here are a few other places to consider:

• Cathedral ceilings
• Walls
• Crawl spaces
• Around ductwork
• In basements
• Floors above cold spaces

Additional Insulation Considerations

Up to 70 percent of a home's energy usage comes from heating and cooling. Properly installed insulation can lower energy costs and increase comfort. Here are a few factors to consider before starting an insulation project, according to the U.S. Department of Energy.

• First, determine the quality of any existing insulation.
  • Southern U.S. homes should have R-30 insulation
  • Northern U.S. homes require R-38 insulation
• If existing insulation is R-19 or is less than the recommended R-value, consider adding more insulation
• Determine the location of heating and cooling air ducts and assess how well they are sealed. Repairing leaks or resealing air ducts can contribute significantly to year round energy savings.
