How Much Does It Cost for Spray Foam Insulation?

Spray foam insulation is a fantastic investment because it can help you lower your heating or cooling bills. It can also help soundproof your home, which is crucial if you live in a densely populated area or if your home is along a busy street.

Spray foam insulation cost will depend on how large your house is, but it usually starts at around $1,900 to $4,000 per house. The average hourly labour rate for spray insulation is between $50 and $120 per hour, depending on the experience of the spray insulation specialist you will hire.

Costs of Different Types of Spray Foam Insulation

One factor that affects spray foam insulation cost in Australia is the type of spray insulation you’ll use. There are several types of spray insulation that you can choose from. These are:

Open-cell foam

This is a type of insulation full of cells with cells that are intentionally open. The open cells result in a foam that is softer and more flexible. Open-cell foam performs better as a sound-dampener than closed-cell foam. Open-cell spray foam costs around $0.40 to $0.60 per board feet.

Closed-cell foam

As its name implies, this type of insulation has completely closed cells. The cells in a closed-cell foam get pressed together to prevent air and moisture from getting inside the cells resulting in a more rigid and durable material. Closed-cell foam is more expensive than open-cell foam and costs around $1.25 to $2.50 per board feet.

Foam Thickness

The thicker the spray insulation is, the better it will perform for you and the lower your utilities will become. Thicker spray insulation also means higher R-Value. You can add several layers of both open-cell and closed-cell foams to achieve a higher R-Value. However, expect the cost of spray foam insulation to increase because the tradie will use more materials and spend more time during the installation.

R-value

R-value is a measurement that indicates the level of performance of your spray foam insulation. It is a measure of the foam’s ability to resist conductive heat flow.

While hunting for spray insulation, keep in mind that a higher R-value means better insulating capabilities. The R-value of spray insulation depends on the type of insulation, the thickness of the foam and the foam’s density.

Price Estimates for Spray foam Insulation Jobs

You can have spray foam insulation applied to several areas in your house, depending on what you want to achieve. Here are the most common areas that can benefit from spray foam insulation:

Roof Spray Insulation Cost

The most notable benefit of spray foam insulation to a roof is its ability to keep out the heat during summer and during the winter season, resulting in lower energy consumption.

Roof spray foam insulation can also protect your home from water damage. Spray foam insulation gets applied in liquid form, which can help plug-in gaps, cracks and seams in an existing roof, thus helping prevent leaks.

Spray foam insulation can also help level roofs, which can help prevent water pooling, especially during the rainy season.

Depending on the R-value, residential spray foam insulation on roofs may cost between $1,000 and $3,000. House foam insulation cost can also increase depending on the size of the roof.

Attic Spray Insulation Cost

Spray foam is an excellent choice if you want to insulate your attic because of its flexibility. Attics are notorious for small nooks and crannies that are difficult to block but are easy to fill in using spray foam.

Since spray foam can get inside even the smallest of cracks, it is an exceptional insulation material. It acts as an excellent air barrier preventing heat from getting in from the outside.

Spray foam is durable and can last several decades, which makes the cost of spray foam insulation an excellent investment. House foam insulation costs between $1,500 and $3,500, depending on the size of your attic.

Basement

Basements are often damp and cool, making them ideal breeding grounds for mould and bacteria that can cause health issues for your family, so insulating your basement with spray foam can be a worthy investment.

If you live in an old house, spray foam insulation can help prevent leaks in your basement. As a place gets older, cracks can form in concrete and spray foam can help plug-in those cracks to prevent leaks.

Spray foam insulation can also help prevent infestation in your basement. As mentioned earlier, spray foam insulation expands to fill in cracks which can help block the entry of insects into your home. Spray foam insulation estimate for your basement is between $1,000 to $3,000 depending on the size of your basement and the height of the walls.

Garage

Since garages are often without insulating ceilings, insulating them makes perfect sense, especially for stand-alone garages with bare metal roofs. Aside from the ceiling, you can also use spray foam insulation on the walls of your garage, especially if you have a garage with thin walls. Thin walls are poor protection from the heat of summer or chilly winds during the winter.

If you use your garage as a workshop, insulating it will allow you to work comfortably for more extended periods. Insulating the walls on your garage can help regulate temperature so your garage will be bearable even if it doesn’t have an air-conditioning unit installed.

Whether you use high or low expansion foam insulation, spray foam insulation can help protect your garage from pests like mice. If you use your garage as additional storage space, spray foam can protect your belongings from getting damaged by mice.

The average cost of insulating a garage ranges from $450 to $1,000 depending on the size of the garage and using cheap spray foam insulation or affordable spray can insulation can make it even cheaper.
