All You Need to Know about Spray Foam Insulation.

What Is Spray Foam Insulation?

Spray foam insulation defined

Spray foam, also known as Spray Polyurethane Foam (SPF), is a type of insulation that mixes two materials together to create an expanding foam that provides thermal insulation to buildings, keeping them cool in the summer and warm in the winter. 

You may have seen other types of insulation, like Fibreglass insulation (the stuff that looks like cotton candy and makes you itch). While Fibreglass is an inexpensive option to buy and install, many other factors can affect the long-term cost.

For this reason, Spray foam insulation is rapidly gaining popularity as the go-to option for insulating homes and commercial properties.

Types of Spray Foam

There are two types of spray foam, open-cell and closed-cell.  They both have different properties based on your needs and your budget. Let’s compare the two. 

Closed-cell Spray Foam Insulation

Closed cell spray foam is made up of bubbles, or cells, that are closed. Because they are closed, this spray foam prevents air and moisture from getting into the foam. It is also much denser and more stable than open-cell spray foam insulation and can provide extra structural integrity. This is the more expensive option.

Open-cell Spray Foam Insulation

Open-cell, on the other hand, has cells that are left open, and this type of material is more flexible and softer than closed-cell spray foam and can also penetrate hard-to-reach areas easier than more dense closed-cell spray foam. It also provides effective sound insulation. 

What Are the Benefits of Spray Foam Insulation?

While spray foam isn’t the cheapest option, you get what you pay for. There are many benefits to using spray foam in your home or commercial property over other types of insulation.


Energy Efficiency

Spray foam insulation is the superior insulation. It provides a tight seal that prevents air leaks and keeps the air temperature inside the way you want it. Spray foam insulation can help you save on your electric and gas bills when heating your home in the winter and cooling it in the summer. 

Due to its high R-value,  spray foam is superior to other types of building insulation. 

R-value measures how well something can keep heat from escaping or entering a space. The higher the R-value, the better the insulation works. Closed-cell spray foam has an R-value of 6 or 7 per inch. Open-cell spray foam insulation has an R-value of 3.5 per inch. Compare this to fibreglass insulation with an R-value of 2.2 per inch; you can clearly see the benefits.  

Moisture and Air Barrier

Spray foam is an insulation and air and moisture barrier all in one. Most vapour issues result from air leaks, so you don’t need to install a vapour barrier in many areas as you would with fibreglass insulation. However, there are still areas where a vapour barrier is required, like around sump pumps and drains, but for the most part, spray foam insulation keeps dampness from getting in, which prevents mould from growing. 

Noise Reduction

Open-cell spray foam insulation, specifically, is excellent for trapping sound with its open-cell structure (air bubbles). In addition to keeping your home temperature where it needs to be, it can provide added value to reduce unwanted sounds from entering or escaping your home or business. 

Keeps Out Allergens

Spray foam insulation can keep out dust and pollen; tying this back to cost saving, it can also reduce the wear and tear of HVAC equipment in your home or business.  


Spray foam can last up to 80 years, whereas some forms of fibreglass insulation only last 15  to 20 years. Replacing Fibreglass insulation would be necessary before you even pay off your mortgage.

Why Spray Foam Insulation Is Good for Homes.

Spray foam insulation importance

Spray foam insulation is an excellent option for homes for all the reasons listed above. Still, there are other reasons why spray foam insulation is a good solution for home insulation, such as increased home value. 

Installing spray foam insulation can increase the value of your home by improving its energy efficiency, comfort, and overall appeal to potential buyers.

Why Spray Foam Insulation Is the Most Cost-effective Choice for Businesses.

As a business owner, you value long-term investments. Spray foam insulation is a smart choice for businesses because it offers:

  • Cost-effective long-term energy savings
  • Durability and long-lasting performance, reducing overall costs from repairs and replacements
  • Improved indoor air quality and prevention of moisture and mould growth

Spray foam insulations’ superior insulating properties make it a worthwhile investment despite its higher initial cost. Don’t overlook the benefits of spray foam insulation for keeping your business’s bottom line and employees healthy long term.

Why You Should Avoid DIY Spray Foam and Hire an Expert Insulation Service.

If you’re considering insulating your home or building with spray foam insulation, it may be tempting to take a DIY approach to save money. However, DIY spray foam insulation can be risky and potentially dangerous, and there are several reasons why you should avoid doing it yourself and hire an expert insulation service instead. Here are a few key reasons:

Health & Safety Concerns

Spray foam insulation requires special equipment and safety gear, including respirators and protective clothing, to avoid exposure to harmful fumes and chemicals. There is a risk of injury or illness without the proper training and equipment.

Proper Installation

Applying proper spray foam insulation requires specialized equipment, knowledge, and experience to ensure a correct and uniform application, as well as to prevent gaps or voids that could compromise its effectiveness. Improper installation can lead to problems like mould growth, moisture buildup, and reduced energy efficiency. Professionals do this repeatedly so they get the job done right the first time, every time. 

Professional Expertise

Professional insulation services have the knowledge, skills, and experience to evaluate your specific insulation needs and recommend the best solution for your home or building. They can also provide ongoing maintenance and support to ensure your insulation continues to perform effectively over time.

By hiring an expert insulation service for your spray foam insulation needs, you can ensure safe and effective installation, leading to long-term energy savings and, most importantly, peace of mind.
