Exploring Spray Insulation, Is Spray Foam Insulation Worth It?

Are you thinking about the cost of using spray foam insulation? If so, you are in the right place. Mostly, several factors affect the cost of spray foam insulation. Before looking at the cost of spray foam insulation let us first look at its worth.

Is Spray Foam Insulation Worth It?

Some homeowners are scared of the commitment and spray foam insulation cost in their property. If you don’t know the advantages that spray foam insulation brings to your home, you will indisputably ignore this option. Here are the benefits of spray foam installation.Spray foam is often used in new property but can also be used with existing ones. When you utilize spray foam insulation within your property, you will observe substantial savings in your energy costs, with the majority of property owners saving up to 40%.

One major advantage of spray foam insulation is its moisture barrier and air-sealing properties. Once the foam is applied directly into small gaps and cracks, it will expand and dry quickly to block moisture and air.

How is the neighborhood you are living in? Do you have neighbors who party frequently? Spray foam insulation will make your home more comfortable as it will significantly reduce noise. Spray foam insulation reduces noise than any other form of insulation.

Another benefit of spray foam insulation is reducing the number of allergens and pollen’s that enter a home through the walls. When the foam reaches gaps and cracks, allergens and pollen cannot get through the walls. By reducing the amount of allergens and pollen that get into a property, you help those with respiratory conditions and allergies. Therefore, you may end up saving on medical expenses.

Usually, small cracks and gaps within a property are open invitations to bugs, ants, and rodents. Luckily, when the cracks are filled, it gets hard for bugs and small rodents to get into your home. Keeping away bugs and rodents away from a house will reduce the risk of you and other occupants getting diseases from rodent waste.

Spray foam insulation prevents mold and mildew growth. The foam product used is usually made up of an inert polymer, meaning it does not provide a food source for mold, mildew, or bacteria build-up. The less water penetrates the walls, the smaller the chance of developing health problems caused by mold and mildew growth.

Because of its hardness and density, spray foam insulation will increase the robustness of your walls. When a building is built, its walls have to meet a minimum weight bearing standard to support the structure. However, this standard does not consider mother nature. Heavy snow, strong winds, and hurricanes can be challenging to the structure of your home. Insulating your attic with spray foam will protect your roof during these harsh weather conditions.

Spray foam insulation lasts longer compared to other types of insulation, such as Styrofoam and fiberglass insulation. Styrofoam insulation breaks after some years, while fiberglass bunch and sags. On the other hand, spray foam insulation does not break or sag over an extended time. Although the initial investment cost of spray foam insulation is high, it will save you money in the long run as they will be no need to replace the insulation over time.

If you are an Eco-friendly property owner, use spray foam insulation. This is because spray foam minimizes energy consumption within your property. Since spray foam insulation is durable, it consumes fewer materials.

What is Spray Foam Insulation?

Spray foam is an insulation material with two liquids that air seals and insulates whenever it is utilized. The liquids come in two big 55 gallon barrels – a resin and an isocyanate. These liquids are stored alone until applied by a professional. The liquids go up a heated pipe to the spray gun where they mix to produce the foam. Within seconds, the foam will expand to fill cracks and gaps.

Where is Spray Foam Insulation Best Used?

Spray foam is used in the following areas:

  • Walls
  • Floor assemblies
  • Attics
  • Foundation wall exterior
  • Under slabs to radiate heat
  • Ice houses
  • Hot roofs
  • Crawl spaces
  • Insulated trailers

Why is Spray Foam Insulation So Expensive?

On average, spray foam insulation ends up costing $3,000. Thus, spray foam is costly compared with other forms of insulation. Many property owners don’t know why spray foam insulation is that costly.Spray foam insulation is expensive because the materials, equipment, and keeping expert installers on staff are expensive. Here are some extra variables that affect the cost of spray foam installation.

  • Type of material used
  • Amount of material needed
  • Time required doing the job
  • Additional work required
  • Property location
  • Insulation thickness
  • Parts of the property to insulate

How Well Does Spray Foam Insulation Work?

Spray foam insulation not only insulated the applied area but also functions as an impenetrable moisture and air barrier without the requirement of a detached air barrier. Spray foam insulation has heat transfer properties and is much effective in reducing airflow through openings, cracks, and gaps. Therefore, spray foam insulation has superior sealing capabilities and the greatest insulation value of any insulation product.The other beauty of spray foam insulation is its ability to form a continuous barrier. Be it a renovation project or new construction, spray foam insulation covers every crevice and crack and all types of even and uneven surfaces. A professional spray foam installer will penetrate the hard to reach cavities those other insulation products can’t.

No other insulation product in the market can insulate and seal to the degree of spray foam.

Is Spray Foam Insulation Worth The Extra Cost

Spray foam is worth the cost because it reduces energy bills. Spray foam has a high R-value making it effectively block heat away from your property. This will lead to low energy costs, especially during winter. If you live in a region with hot summers, you will observe lower energy bills since spray foam keeps your AC unit from working as hard.Spray foam is worth its high price tag as it protects property from moisture damage. Spray foam is impermeable to moisture and also does not absorb moisture. Spray foam is dense, and therefore water rolls off its surface. Spray foam may be expensive, but it eliminates the cost of repairs caused by water damage.

Spray foam is worth its high price as it seals surfaces. Property, especially old ones, might develop cracks between the boards that make up its walls and ceilings. There may also be small gaps around pipes and electrical cords. These spaces let in water and air. Spray foam insulation will effectively fill these gaps, saving you time and effort.

Does Spray Foam Insulation Save You Money?

Heating and cooling account for up to 50% of your home’s energy usage. Homeowners who have spray foam have registered a 20% decrease in their monthly energy bills. Therefore, reduced monthly bills will end up saving you a lot of money.

Having spray foam insulation will lead to decreased property repair costs. When air leaks out, your air conditioner will be forced to work harder to maintain the temperature. This extra work will make your AC break down, thus needing repair: ac repair is costly. When you use spray foam insulation air cannot enter your home, and your air conditioner runs smoothly; saving you money on repair costs

Spray Foam vs. Fiberglass Insulation

Spray foam and fiberglass are the most common types of insulation. Fiberglass insulation comprises of plastic mixed with glass to form fibers. On the other hand, spray foam has polyol resin and isocyanate to form an effective insulator. Here is how spray foam and fiberglass insulation compare.


The R-Value refers to the resistance of an insulator to heat flow. A higher R-Value indicates a more effective insulator. Spray foam insulation has an R-Value ranging about 3.4 to 6.4 per inch. Meanwhile, fiberglass has an R-Value of about 2.2 per inch. Additionally, spray foam insulation maintains its R-Value, while fiberglass insulation loses its effectiveness over time.


Spray foam insulation is significantly costlier than fiberglass insulation. In some circumstances, the cost of spray foam insulation may surpass that of fiberglass up to three times.


Spray foam is a sophisticated but highly effective insulation material that will keep you comfortable and save you money. Now that you have learned about spray foam insulation cost contact us and get a free estimate today.
