Reflective or radiant barrier foundation usually costs between $700 and $2,900. Depending on the thickness and brand, materials cost $0.25 to $1 per square foot. To insulate a 500-square-foot attic, expect to pay between $125 and $500; double-sided radiant barriers are more expensive. Professional installation will add approximately $575 to $750 to the overall total. Radiant barriers technically don’t have an R-value because the sheeting reduces heat gain by re-emitting radiant heat instead of absorbing it.
Foam Board
Spray foam insulation costs $0.50 to $2 per board foot depending on if you choose to seal leaks and gaps inside existing walls. This insulation is the perfect solution for those who are looking for a relatively inexpensive way to fix a larger problem, while increasing their home's R-value. When done properly, spray foam can save you $500 or more a year in energy costs.
Cost of Cavity Wall Insulation
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. The location in your home that needs insulation can also greatly affect the overall cost. To be as energy-efficient as possible, a house should be insulated from top to bottom in areas such as the garage, basement, attic, roof and the walls.

Insulating a basement costs $1.20 to $2.90 per square foot installed or $600 to $4,600, depending on the size and insulation type. Spray foam and rigid foam board work best as they provide insulation and a vapor barrier to block moisture. The cost to insulate a garage is $600 to $3,400, depending on the garage size and insulation type. DIY fiberglass batts in garage walls cost $100 to $720, while professional spray foam insulation for a 2-car garage costs $2,600 to $8,900.
Average Cost to Insulate an Attic
Prices can range from $0.25 and $2 per inch of thickness per square foot (one board foot) or $1 to $5 per square foot. The cost of labor to install insulation averages between $0.25 to $0.50 per square foot. The overall labor cost depends on what type of insulation is installed. Batting insulation can be a quick installation process, while spray foam takes more time and preparation. Insulation costs $0.30 to $4.50 per square foot installed, depending on the type, material, R-value, location, project size, and job complexity. With careful planning and preparation, it is entirely possible to install certain types of home insulation by yourself.
Average Costs for Home Insulation
By installing new insulation, you won’t have uneven temperatures throughout the house, and the heating and cooling system won’t have to work overtime. If there are signs of water or moisture in the ceiling or attic, it may be a sign that a home is under-insulated or the insulation is damaged. High temperatures and extreme heat can create condensation, which can cause moisture to pool. Pooling water in the attic or ceiling can produce mold and mildew, posing severe health and safety risks.
To pay for a professional installation, add $575 to $750 to that cost. Typically installed in attics, loose-fill insulation is also sometimes used to backfill wall cavities. Made from white cellulose, you can find reclaimed and recycled varieties. For DIY projects, you can purchase bags of it at a home improvement store and rent a blower for under $100 a day. If the insulation professional needs to remove old insulation, there may be an additional removal and disposal fee.
On average, removing the existing insulation costs between $1 and $1.50 per square foot, not including disposal fees. Removing fiberglass insulation batts is less expensive than removing blown-in attic insulation, since the latter requires special machinery or a large vacuum for removal. Polystyrene insulation is used to make foam boards or spray foam insulation. The foam board is used to cover the exteriors of buildings (under roof shingles or siding) while spray foam is used to fill wall cavities or under attic floors.
Energy audits are eligible for a 30 percent federal tax credit, up to $150. Air sealing is necessary for the most energy-efficient attic before you install your insulation. Air leaks in the attic can waste a ton of heat during the winter, making cooling your home during the summer impossible. Therefore, your attic insulation can only do its job with air-sealing cracks or gaps beforehand. Spray foam insulation is similar in application to blown-in insulation. As the name suggests, this type of insulation is made of foam, instead of bits of material.

As a result, the attic insulation cost per square foot of spray foam insulation runs slightly higher than other types, around $3 to $5. Below, we’ve listed a breakdown of the attic insulation costs per square foot for many of the most common types of materials on the market. Most insulation projects are DIY friendly, with the only drawbacks being time and mess. For the best DIY solutions, try fiberglass roll and batting or rigid foam boards. Labor costs to install insulation typically run from $0.25 to $0.50 per square foot.
There are two types, open-cell or closed-cell foam with the latter being more expensive, but denser and thicker and thus, better for trapping heat. Spray foam insulation is much trickier than its blown-in cousin and should be handled by a professional. Blown-in insulation is applied using a machine to blow the insulation material into a liminal space between the outside and the space to be insulated.
If you don’t want to spend the cash for this home improvement project, here are a few options to make paying for it more manageable. A budget-friendly home insulation project costs from $640 to $2,780, depending on the size of the home and the type of insulation. Inhabitants can reap the benefits of properly installed and high-performing insulation year-round. New insulation for walls, floors, attic, or basement is an excellent investment for a home. Insulation is the simplest way to save money on heating and cooling costs. Since insulation regulates the temperature inside your home, your HVAC system doesn’t have to work as hard to keep it at a comfortable level.
That allows it to infiltrate even the smallest nooks and crannies for superior temperature control. If you’re living in a home that has no insulation in the attic, don’t let another summer approach without fixing the issue. Consult our guide to determine the average cost to insulate an attic, then find an insulation professional to help you keep your home’s temperature under control more easily. You’ll also want to consult a pro for any blown-in attic jobs and roof work, as those require specialized skills and equipment.
Not only can insulation help reduce the noise that enters your home from the outside, but it also prevents noise from traveling between rooms. Home insulation can be made out of a number of different materials that each have advantages and disadvantages. Some materials can only be used in certain locations and some are only used for new construction as opposed to when adding or replacing insulation. Below are the most common insulators, common applications and average costs. While DIY-ers can rent an insulation blowing machine, we recommend hiring a professional for this service. The average cost of blown-in insulation is between $1.65 and $3.80 per square foot.
