Combien coûte l’installation d’une isolation ?
Hello, my friend, hello again; today we come together to talk about How Much Does Insulation Cost to Install? and hope the blog can help you.
Votre maison a-t-elle besoin d'une nouvelle isolation ? Les coûts d'isolation varient entre 1 400 et 6 300 THB, la moyenne nationale étant de 2 900 THB.
- Plage typique : $1,400 to $6,300
- Moyenne nationale : $2,900
If you’re experiencing a drafty house, high energy bills, attic moisture, uneven temperatures from room to room, and a constantly running HVAC system, your home may need new insulation. Selon HomeAdvisor, home insulation cost options range from $1,400 to $6,300, with the national average for blown-in insulation at $2,900. Blown-in insulation costs less than batting, radiant barrier, and fiberglass insulation. The most expensive option is spray foam insulation, but it has the highest retour sur investissement (ROI).
Insulation cost is measured per board foot, which is 1 square foot by 1 inch thick. Expect to pay between $0.25 and $2 per inch of thickness per square foot (one board foot) or $1 to $5 per square foot. The ROI on insulation is at 100 percent or more, and it’s considered one of the best investments homeowners can make to their home. Insulation warms a home in the winter and cools it in the summer by slowing down heat transfer through the walls, floor, and ceiling. Each inch of insulation supplies between a 3 and an 8 R-value. The R-value measures how well a material insulates; the higher the R-value, the better the insulation.
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.

Factors in Calculating Insulation Cost
Calculating insulation costs depends on several factors. Prices can differ from the national average due to the type of insulation, project size, home area, labor prices, equipment, site preparation, and cleanup.
Type d'isolation
Il y a many different types of insulation, and they all differ in cost, advantages, and uses. An insulation professional has the experience and knowledge to advise you regarding what kind of insulation will work the best in a home since some types will work better in certain areas. Some of the most common types of insulation are spray foam (open-cell foam and closed-cell foam), blanket insulation that includes batts and rolls, loose-fill or blown-in, rigid foam board, and structural insulated panels (SIPs).
Taille du projet
Insulation costs depend on the total square footage of the project. The area per board foot and the required R-value, as well as the project’s preparation and cleanup costs, will determine the overall insulation installation pricing. 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.
Room or Part of the Home
Where the insulation needs to be installed also affects overall insulation costs. For energy efficiency, a house must be insulated from top to bottom. Here are some areas of a home that need insulation, the most common type of insulation for that location, and average prices.
- Garage insulation cost. It costs approximately $0.50 to $1.25 per square foot for garage insulation (not including the garage door). The price may double if you have a professional install the insulation. The total cost can range from $1,500 to $8,000, depending on the size of the garage and the materials used. Keep in mind that attached garages only need the external walls insulated. Insulating a garage door with batts or rigid foam costs around $200 to $300 for a 9-foot-tall door.
- Floor and crawl space. Crawl space insulation costs range from $1 to $5 per square foot, depending on the type of material you choose. Many homeowners spend between $500 to $1,500. To insulate a crawl space, you can insulate the space’s ceiling (the interior floor) or the walls. The most common materials used to insulate crawl spaces are spray foam, fiberglass, and rigid board. Insulated concrete forms can be used for new construction, and they cost between $150 and $160 per square foot. This cost typically includes the price of the poured concrete wall.
- Basement insulation cost. The cost to insulate a basement usually runs between $1.50 and $2.50 per square foot. A basement rarely needs as much insulation as the rest of the house since the surrounding terrain helps keep the area cool in the summer and warm in the winter.
- Attic insulation. Homeowners can expect to pay between $1,500 and $6,000 to insulate an attic, depending on what type of materials are used. Spray insulation foam usually gets installed first, followed by batts or blown-in insulation. The attic is the most important part of your home to insulate since heat rises. Many homes have twice as much insulation in the attic as they do in the walls to protect against losing warm air.
- Roof insulation cost. Expect to pay from $1,500 to $4,500 or more for roof insulation. Roof insulation can allow you to convert an attic space into a livable area. Attic conversions typically cost $40,000, and most times, that price can be bundled with new roofing. Roof insulation can be done during or after construction. If it’s done during construction, a roofing professional can install layers of rigid foam board beneath the shingles, or you can have batting or spray foam installed along the rafters in the attic.
- Wall insulation. Wall insulation costs approximately $1 to $4 per square foot. Mineral wool and fiberglass batting costs between $1 and $1.50 per square foot to install. Newly constructed homes use reflective, rigid, spray foam, or a combination of all three, which can cost $3 to $4 per square foot.
- Pole barn insulation. It costs between $1 and $4 per square foot to insulate a pole barn. Many insulation professionals recommend spray foam or fiberglass batting with a thick polypropylene sheet. Spray foam is pricier, but it does a better job at preventing air leaks. Some homeowners will opt for a thin layer of spray foam covered with fiberglass batting to stay within their budget.
- Mobile home insulation cost. Fiberglass batting can cost between $0.25 and $1 per square foot to insulate a mobile home. If you decide on thicker materials installed by an insulation professional, the costs can range up to $3 per square foot.
Main-d’œuvre et équipement
Labor costs to install insulation typically run from $0.25 to $0.50 per square foot. This price can differ from the national average depending on what type of material is used and how big the area is that needs to be insulated. Some types of insulation require specific equipment to install it. Spray foam, for example, requires special equipment to install since it comes out as a liquid and transforms into dense foam. Spray foam will cost more due to the equipment and protective gear that is needed for the project.

Site Prep and Cleanup
Site preparation and cleanup will also make up a significant portion of the overall project cost. Preparation involves any needed repairs to the walls, attic, basement, or crawl space. If there is water damage or evidence of mold or mildew, a home may require mold remediation services before a contractor can begin insulation installation. The costs for site prep will be based on the extent of the repairs and types of materials needed. Cleanup costs include removing old insulation and other materials.
Coûts et considérations supplémentaires
When budgeting for insulation costs, there will be additional price factors and considerations beyond the basics. These include insulation removal, insulation replacement, and home air sealing.
Retrait ou remplacement de l'isolation
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.
Most insulation eventually loses its R-value and will need replacement. Replacing insulation costs between $2 and $7 per square foot for fiberglass and most blown-in insulation. Keep in mind that spray foam insulation cannot be removed entirely, and rigid foam boards are typically the easiest to remove. Once the old insulation is removed, a professional will seal and patch the area and refill it with the new insulation.
Home Air Sealing
It’s important to reduce air movement within a home to maintain energy efficiency. Air sealing techniques like air barriers will help prevent leakage in and out of a home. Air barriers construct pockets to block irregular air movement. They help stave off leakage in and out by using weatherproofing strips and caulking. Another air sealing technique is a house wrap. A house wrap is made from fibrous plastic wrapped around the exterior of a house to prevent air movement. Home air sealing methods are typically implemented when a house is constructed since it’s much easier to do that instead of retrofitting an existing home. The cost of air sealing runs from $350 to $600, depending on the size and scope of the project.
Insulation Cost: Types of Insulation
Depending on the type of insulation you choose, the cost to install insulation can range from $1,400 to $6,300. The average homeowner typically pays around $2,900 for insulation costs. Here are some of the most common types of insulation.

Mousse pulvérisée
Spray foam insulation (SPF) costs between $0.50 to $2 per board foot. This price can vary if you fill gaps and leaks inside existing walls. Spray foam insulation is composed of plastic foam materials to deter air movement and supply thermal insulation. Spray foam insulation is an excellent way to increase the R-value and insulate a home. When spray foam insulation is professionally installed, it can save $500 or more a year in heating and cooling costs—but keep in mind that not all insulation professionals offer this service. While spray foam insulation is more expensive up front, it can save more in the long run. There are two types of spray foam insulation: open-cell and closed-cell. The “cell” refers to the bubbles that make up the foam.
- Open-cell. Open-cell spray foam insulation costs between $0.35 and $0.55 per board foot. Sometimes called half-pound, this type of insulation is an excellent air barrier, but it’s not a water vapor barrier. Open-cell spray foam has bubbles that are intentionally left open. This insulation is softer, more flexible, and less dense than closed-cell foam insulation. The R-value of open-cell insulation is about 3.5 per inch. It’s designed to expand about 3 inches. Only one application of open-cell spray foam insulation is feasible in standard-size walls.
- Closed-cell. Closed-cell spray foam usually costs $1 to $2 per board foot. Closed-cell insulation excels as an air and water vapor barrier. The cells in this type of spray foam are thickly packed to ensure that no moisture or air can infiltrate a home. Because of the density, it is also more resistant to pests than open-cell spray foam insulation. Closed-cell foam has an R-value of 6 to 7 per inch, making it ideal for homes in extreme climates.
Insufflé
Blown-in insulation typically costs $1,000 to $2,100. Also known as loose-fill insulation, blown-in insulation is usually installed in attics, enclosed existing walls, or open-wall cavities. Blown-in insulation comes in three types: fiberglass, cellulose, and mineral or rock wool. You can buy cellulose blown-in insulation in reclaimed or recycled varieties.
Batt
Fiberglass batt insulation is the most common type of insulation. It comes in rolls or batts, and it’s the most economical form of insulation. While it’s made primarily of fiberglass, it also can contain plastic fibers, mineral wool, or natural fibers. It usually costs between $0.30 and $1.50 per square foot or between $1,000 and $2,400 on average. When an insulation professional installs it correctly, fiberglass batt insulation can improve energy efficiency by 25 to 30 percent.
Rigid Foam Board
L’isolation en mousse rigide des murs coûte en moyenne entre $0,90 et $1,88 par pied carré. Les panneaux de mousse rigide emprisonnent les gaz et l’air pour empêcher la circulation de la chaleur. Ils sont généralement utilisés pour isoler les toits non ventilés à faible pente, les plafonds et les planchers, mais ils peuvent également être utilisés dans les murs de fondation. Les panneaux de mousse rigide sont disponibles en différentes épaisseurs et un professionnel de l’isolation peut déterminer l’épaisseur appropriée à la maison et à l’emplacement. Les panneaux de mousse sont fabriqués à partir de polystyrène, de polyisocyanurate et de polyuréthane. Ces panneaux offrent un niveau d’isolation élevé pour un panneau plus mince. Les panneaux peuvent être utilisés sur les murs intérieurs et extérieurs, mais ils doivent être recouverts de matériaux approuvés pour la sécurité incendie.

Fibre de verre
L’isolation en fibre de verre est constituée de fines fibres de verre et se présente sous forme de rouleaux ou de matelas, ainsi que sous forme d’isolation soufflée. Elle est couramment utilisée pour isoler les cavités murales, les planchers, les vides sanitaires et les murs. La fibre de verre est un
