Take note that some insulation costs are measured per square foot, while others are measured per board foot. Cellulose insulation is nearly exclusively used for loose-fill and is blown into existing wall cavities. Most commonly, it comes in a damp spray form and sticks together as it settles into the walls. The cost range for cellulose insulation is $0.60 to $2.30 per square foot. This type of insulation is much thinner than blanket insulation but is one of the most efficient types, by thickness, on the market. The average cost of foam board insulation is between $2.40 and $3.75 per square foot.
This is because spray foam helps to regulate the temperature in your attic, keeping it cool in the summer and warm in the winter. As stated in the energy savings section, spray foam helps air seal your attic. This is great because a well-sealed and insulated attic can help improve your home’s indoor air quality. By sealing off any cracks or gaps, you are also keeping out any outside allergens, dust, and pests that might want to make their way into your home. First, we need to know why it’s essential to talk about your insulation options. A poorly insulated attic can cause a slew of issues, from costing you money to rotting wood beams.
Removing and Replacing Existing Insulation
The amount of insulation needed depends on the type and R-value, area of the home being insulated, and local climate. Colder regions require higher R-values, meaning the insulation layer must be thicker. Blown-in insulation machine rental costs $100 to $200 per day on average.
Spray foaming the rim joists costs $1,200 to $2,000 on average for labor and materials. Projects involving removing drywall to access the joists cost more. Insulating the rim joists with closed-cell foam reduces baseboard drafts and improves the home's structural integrity. You’ll pay $1 to $4 per square foot to insulate a pole barn.
Your Premium Option: Spray Foam Insulation Benefits
The thickness of the wall cavity is typically 5.5 inches, with most homes having 2×6-framed walls. This results in an approximate insulation value of R-21, depending on how densely packed the insulation is. In the guides, the reasons for insulating each area are covered along with the recommended R-value of insulation for your climate zone. We include a wealth of information from the US Department of Energy and other reliable sources in the resources at the bottom of each page. Insulation by Material – We offer comprehensive insulation information for the major types of insulation used in construction and remodeling. The guides describe the materials and the benefits they deliver to your home.
In fact, the square footage of your attic is going to be the biggest deciding factor on how much it’s going to cost. Water leaks can happen from a roof issue but can also be caused by the trapped moisture in your attic. If you see any water stains on your ceiling, it’s time to investigate. Your attic’s insulation and ventilation work in tandem to ensure proper airflow and temperature control.

You will find the R-value you need for your home depends on where you are located. Homes in colder regions, like Alaska, require higher R-values than homes in Florida. But where your home is located isn’t the only factor to consider. Now that we know what an R-value is and how the different materials add up, let’s talk about how to figure out what R-value you need.
Hire a professional or measure and weigh before installing dense-pack insulation to ensure the density reaches 3.5 pounds per cubic foot. 2x6 wall framing fits up to R-23 insulation with a 5.5-inch thickness. 2x4 wall framing fits up to R-15 insulation with a 3.5-inch thickness. The minimum recommended R-value for wall insulation is R-13 to R-21, depending on the home's region and wall framing. Off-grid homes are on an uptrend because there are more options available for self-sufficiency than ever before.

But oftentimes, more factors come into play than just dollars and cents. Let’s say, for example, you need insulation with an R-value of 30. To determine how many inches of insulation you need, take your desired R-value and divide that by the material’s R-value. You also need to consider where in your home you will be installing your insulation. Attics and basements require very different R-values than interior walls.
Garages are rarely insulated when they are first built and many people only insulate them if they finish the space or add a living space above it. Some people also insulate garages to reduce the energy costs of heat loss. The average cost to insulate a two-car garage is $0.50 to $1.25 per square foot, which does not include the garage door. The average cost to insulate an attic ranges from $400 to $3,350. If you have a small attic, you may want to insulate it as part of a larger project because most companies have minimums of $1,500 to $2,000.
The cost of cellulose insulation averages $0.60 to $2.30 a square foot. The dense-pack material is more commonly used in attics and crawl spaces. Insulating an attic costs $1,500 to $6,000, depending on the materials you use. More commonly, spray foam gets laid first, then covered with batts or blown in. Since heat rises, it’s one of the most important parts of your home to insulate.
USA Insulation is a healthier, cleaner, safer, quieter type of insulation with a higher R-Value. When you compare insulation types, you’ll discover the many advantages of USA Premium Foam Insulation. The national average spray foam installation cost is $2,500, or $1.50 to $4.90 per square foot, including materials and labor.

They remove bad odours and moisture, helping to lower humidity levels and reduce condensation. The next product is a little more expensive but works very well and is perfect for homes with condensation issues. That probably explains why so many window installers don’t bother fitting these vents, even though they’re easy to install.
It takes much longer to insulate a solid wall rather than a cavity wall and costs considerably more. You’ll either need to alter the exterior of the building or lose precious space internally. Cavity wall insulation is a fibre or polystyrene material that is blown between the two walls via pre-drilled holes and is a great way to reduce heat loss.
Costs are affected by the type and how accessible it is to reach when removing. When removing old and moldy insulation or adding insulation to areas that may have been damp, treat for mold first. Mold remediation removes affected areas and prevents mold from returning, so you can safely insulate. Some are affected by moisture, others by rodent or pest activity, and many types can settle, shred, or become less effective with time. If your goal is to provide long-lasting insulation, you may have better results with some materials over others.
