Blown-in insulation is preferred in attics because it easily fills gaps, joints, and hard-to-access areas. Insulating an attic lowers energy bills, improves indoor air quality, and stabilizes indoor temperatures. Blown-in wall insulation costs range from around $1,000 to $1,500 per 1,000 square feet of actual wall space .
May require the wall cavity to be free of other insulation. Basically, it represents how well the insulation slows down the transfer of heat. The higher the R-value, the better the insulation, the slower you lose heat in the winter or gain heat in the summer.
Home Attic Insulation Cost
Attics are usually fairly wide open, which makes spraying with blown-in insulation relatively easy. Homeowners may choose to tackle this project themselves, though that leaves them responsible for clean-up. Instead, hiring a contractor will cost more, but they’ll handle the clean-up and likely finish the job sooner. Rock wool insulation is fiber insulation made from volcanic rock. The rock goes through a melting and spinning process which extrudes small fibers, creating a lofty pile, not unlike fiberglass. Rock wool is fire retardant, mostly unaffected by moisture, sound-resistant and repels pests.
We'd had new roof insulation and decided to get our cavity walls filled with insulation. Insulating your roof costs anywhere from $1,500 to $4,500 or more. This creates a conditioned space that you can then convert into a living space. Most attic conversions cost $40,000 and you can often bundle the price in with new roofing.
Fiberglass Insulation
Attic insulation companies recommended open-cell foam in vented attics to fill floor nooks and crannies, but it may require a vapor barrier in cold climates. The cost of fiberglass3 insulation is $0.40 to $1.50 a square foot. It comes in batts and loose-fill and can be used in most interior spaces.
All new buildings, including new homes, must be built to stricter energy requirements. These include the amount of insulation and resulting R-values that must be achieved in each area. When building a new home, speak to your contractor about what requirements may be in your area. Preventing thermal transfer is a good start at creating an energy-efficient home. The next step is to find and seal air gaps in your exterior. Air sealing prevents energy from escaping through small cracks or poorly fitted windows and doors.
Estimates
The wood fiber is formed into large, heavy boards and can only be installed on flat surfaces. Wood fiber insulation is commonly used as a supplementary layer of insulation and not as the primary insulator in a space. The median cost of wood fiber insulation ranges from $4.25 to $6.75 per square foot. Rock wool or mineral wool insulation is made of recycled furnace slag and spun into fibers. It insulates better than fiberglass but it is much more expensive. Rockwool contains silica so it should only be installed by professionals who can take proper safety precautions to contain the dust.
For your price range, simply multiply the prices listed below by the thickness you need. Each inch of insulation provides between a 3 and an 8 R-value. R-value rates how well the material insulates, the higher the value, the better the insulation. As we mentioned earlier, mineral wool is similar to fiberglass insulation in many ways. You can expect to pay between $0.50 to $1.50 per square foot.
Insulation Removal Cost
This will usually include the cost of labor as well as the cost of disposal . If you decide to do this , it will cost around $1.00 to $2.00 per square foot. You may need to remove any old insulation in advance of adding additional material. This will usually add $50 to $70 to the cost of the project. For blown-in insulation in an area of 1,000 square feet, you will pay $1,000 to $1,500 for installation.

Loses air, shrinks and experiences loss of “R-Value” or insulation effectiveness over time. Another common potential problem is over application of Spray Foam. Blown-in insulation lasts 20 to 30 years or more, depending on the insulation type, moisture levels, and whether it is disturbed. Blown-in insulation may degrade at 15 years in areas with extreme weather conditions. Increased utility charges are often a sign the insulation needs replacing. However, it is challenging to know which brand to choose, what size and type of unit to go for, and who you should get to install the system for you.
USA Premium Foam® Insulation not only has a higher R-Value but also provides a range of benefits that most other common forms of insulation don’t. However, 7 “zones” in the United States indicate how high of an R-value you need based on climate. For example, Zone 1 in Florida only requires R-values of R13-R49 due to the much warmer climate.
In 2×6 framing, the R-value offered by thicker batts increases to about R-21. While each one has its unique benefit, not every option will be perfect for your home. Like other insulation options, the price to install rigid foam boards is going to depend on where in your home you choose to install them. But you can figure on rigid foam boards costing between $0.25 to $0.50 per board foot. Insulation costs will vary depending on where you live and the type of insulation you choose. In general, you will find the higher the R-value, the more expensive the insulation.
The following table reflects the average cost to install spray foam insulation. "I moved into a new home and found the heating costs were really high. I needed to get cavity wall insulation installed for the coming winter. One advantage of loose fill insulation is that it can be added to existing walls while batts cannot be.
Cellulose is denser and requires more bags per square foot than fiberglass to achieve the same depth. Still, its higher R-value per inch means that cellulose needs less depth to achieve the same total R-value. When it comes to insulation, both R-values and costs can vary depending on installation choices.
You might spend more upfront, but you will definitely see the savings on your monthly bill over time. Poor insulation can cause this imbalance of temperatures which causes ice dams. If you notice ice dams, it can be a critical indicator that you need to re-insulate your attic or check your roof. This can cause them to need more frequent repairs and age much faster. If you have purchased an energy-efficient HVAC system, you do a disservice by not also pairing proper insulation with it to work its best. Whether you DIY insulation installation or hire a local insulation company, you’ll want to carefully consider the best options for your home.
