Spray Foam Insulation Cost 2021
What is Spray Foam Insulation?
Spray foam insulation is a foaming insulation that insulates and air seals wherever it is applied. Spray foam insulation is versatile and can be used to insulation your roof, loft, walls and floor. It can be sprayed into an open cavity, like in new construction, crawl spaces, attics and rim joists. Spray polyurethane foam will make your building more energy-efficient and comfortable. If you are wondering how much spray foam insulation cost, then you are at the right place.
Unlike conventional insulation materials, spray foam never loses its shape, it fills cracks, gaps and crevices on installation. Spray foam won’t compress, sag or settle over time. Spray foam insulation is produced on site using specialist machinery by fully trained and approved installers.
Benefits of Spray Foam Insulation
Spray foam insulation is ideal for old and new homes. Even though this type of insulation might be more expensive than other types of insulation, the benefits of spray foam insulation can actually save you money on your bills.
We can mention 8 major benefits of spray foam insulation and the reasons why you should use it:
➔ Cooling and heating benefits
One of the most special abilities of spray polyurethane foam is getting into small cracks and crevices. Once the spray foam is applied directly into the cracks, it expands and dries while blocking water and air. This type of insulation isn’t just a blockade for water and air, but for cold and heat as well.
Spray foam can lower your cooling and heating bills depending on where you live. Even though it is more expensive than other types of insulation, spray foam insulation cost is a long-term worth investment.
➔ Spray foam insulation cost is an long-term investment
Spray foam insulation limits air leakage and helps maintain even temperatures throughout the home. Air leaks will waste energy and drive up utility bills.
➔ Noise Reduction
Open cell spray foam insulation has the ability to significantly reduce noise. The open cells inside the spray foam have the ability to minimize more noise than other types of insulation.
➔ No more allergens and pollen into your building
Reducing the amount of allergens or pollen that get through the walls is one of the benefits of spray foam insulation. Due to the ability to reach cracks and crevices, the air cannot penetrate the walls, as it does while you insulate your house with other types of insulation.
➔ Prevent insects, bugs, and small rodents from getting into your home
The tiny holes in your building structure are an open way for ants and bugs to get in. Fortunately spray foam insulation has the ability to fill small cracks, and closed spray foam is your best bet if you are looking to create a barrier against the tiny intruders.
➔ Prevents the growth of mildew and mold
Both closed and open cell spray foam insulation prevent moisture from entering through the walls of your property. The closed cell spray foam insulation works as a barrier against large quantities of water. That means the less water gets through your walls, the smaller the risk of health issues due to mold and mildew.
➔ Increases the sturdiness of your walls
When you insulate your building you are also making the structure of your walls stronger due to spray foam density and hardness. There is a code that every building should be built after and it requires the walls to meet a minimum load bearing standard to hold the building together.
Spray foam insulation acts also as a strong glue holding everything together. If you insulate your attic with closed foam you might save your roof during storms. The additional layer of insulation to your walls can also increase the value of your building.
➔ It lasts longer
Unlike the other types of insulation, spray foam doesn’t sag or break over extended periods of time. Even though the investment is larger, spray foam insulation cost is a long-term money investment.
If you are concerned with keeping your building “green” then spray foam is a good news for you. This type of insulation pays its cost by reducing energy consumption and protecting your building against mold and mildew growth. Since it lasts longer it consumes less materials than other types of insulation.
Types of Spray Foam Insulation
There are two types of spray foam insulation, open and closed-cell spray foam insulation. The open-cell foam insulation is commonly utilized for interior applications such as wall cavities, attics, basement walls, and crawl spaces.
The advantages of open-cell foam insulation include:
Can adapt to long haul creep and seasonal movement
Enables bi-directional drying
You can install it at a lower cost
Doesn’t attract mold
Offerst sound dampening characteristics
Lower average spray foam insulation cost per square foot
Closed-cell spray foam insulation is a hard medium-thickness material which can be used in exterior applications like continuous insulation installations. Closed-cell spray foam insulation has a higher spray foam insulation cost per board foot. Here are the advantages that the material offers:
Capacity to reject mass water
Can be applied at low temperatures
Includes wall racking strength, along with impact resistance
Higher R-value per inch
Lower vapor permeance
Higher tensile and bond quality
Spray Foam Insulation Cost
The spray foam insulation cost is calculated using the board foot. If you want to determine how much you need, you have to multiply the space that you want insulated by the price per inch of insulation. Measured as: square foot x $/inch of insulation per sq.ft.
Spray foam insulation costs range from $1.00 to $6.00 per square foot depending which part of the house you will insulate. For example if you are doing renovations in your first floor and will insulate the exterior walls of approximately 600 square feet. Above-grade exterior wall requires a minimum of R22 which comes to approximately $4/square foot of insulation. In total, the cost of the first floor exterior wall insulation is 600 * $4 = $2400.
We can also give you three simple steps on how you can determine the accurate budget for your project:
Step 1: Try to figure out what you need, determine the type of spray foam that you want to use and applied thickness.
Step 2: Calculate the square footage
Step 3: Multiply the cost of the amount of insulation per square foot by the total square footage.
Other factors to consider that may affect the pricing are:
The accessibility of the area
The type and size of studs in place
The condition of the structure
The ability to ventilate the area
The general maintenance of the working area.
New Home Spray Foam Insulation Cost
The average price to insulate an average-sized new construction home is between $9,000 and $13,000 from the top to bottom. For a 1,000 square feet home, the price ranges between $5,000 and $7,000.
