Spray Foam Insulation: All Questions Answered

Going green has become a growing trend for both commercial and residential properties in recent years. As more people turn to solar energy for power, the need for modern green construction also changes. And whether you own a commercial or residential property, one thing’s for sure: you want to find the best solutions for your real estate investment. 

So if you’re moving forward with your eco-friendly construction project, what are some pro tips that can genuinely help you get your money’s worth? Most contractors may tell you to consider spray foam insulation. Applying spray foam insulation will not only make your home feel more comfortable during extreme weather, but it can also help you achieve your green building goals. 

But what exactly is spray foam insulation, how is it applied, and why might it be an ideal option for your sustainable development project? Let’s find out! 

Spray Foam Insulation

What Is Spray Foam Insulation? 

Like any other type of insulation, spray foam insulation aims to seal floors, walls, and ceiling cavities to resist airflow. To put it simply, it helps keep your home cooler during summer and warmer during the colder seasons. Insulation can be applied to any open cavity, be it in the attic, around electrical fixtures, and even on ceiling crevices. 

Now that that’s out of the way, what’s spray foam insulation? As the name suggests, spray foam insulation refers to an insulation application that uses a spray foam material – also known as spray polyurethane foam (or SPF) 

Spray foam is said to be one of the most efficient options out there for insulation. But before we discuss its many advantages, let’s get to know this material a bit better.

Spray Foam Insulation: What Is It Made Of? 

In brief, spray foam insulation is a combination of isocyanate and polyol resin in the form of a foam-like material. For insulation or roofing, polyurethane is the most commonly used material in the construction industry. There are two types of SPF: open-cell and closed-cell. The former is primarily used for noise reduction, while the latter is used for airflow resistance and water prevention. 

Of course, spray polyurethane foam is not the only option available for insulation applications – fiberglass or cellulose are also available. So why should you choose spray foam insulation? Below are a few reasons why we think it’s an excellent option for your project. 

Is Spray Foam Insulation Worth It? 

Wondering if spray foam insulation is worth investing your money on? We understand. After all, getting any construction job done to your home or commercial space isn’t cheap. But if you ask us, SPF insulation is an ideal option, and here are reasons why: 

Energy Efficient 

With a record between 5.6 to 8 per inch, spray foam has one of the highest R-values among all insulation materials available today. A material’s R-value represents its ability to keep heat from entering or leaving a specific space. A high R-value equals better energy efficiency and a more comfortable climate overall within your living spaces. 

Long-lasting

Compared to other insulation materials, spray foam can seamlessly fill gaps and crevices. Additionally, it also keeps its shape even as time passes. While other materials tend to sag or compress, spray foam does not wear out as quickly. 

Promotes Durability 

In general, any insulation is supposed to add more structure to your home or building. But thanks to the doubled strength of spray foam, your home or building’s durability also increases. Also, applying spray foam insulation to your home is more than just reinforcing its structure; it’s also about protecting the home from other harmful factors such as mold and mildew. Unlike wood or metal, spray foam does not rust, rot, or attract mold and mildew. 

Eco-Friendly 

Last but not least, spray foam insulation fits like a glove with your eco-friendly development plans. Compared to other options, spray foam does the least harm to the environment. Some SPF insulation brands are made from renewable products such as recycled plastic bottles. To top it all off, spray foam produces the least amount of waste as well. 

When renewing your insulation, there’s little to no need to tear off and throw existing material. All contractors have to do is to add a new layer, and the job is done. 

Is Spray Foam Insulation Safe For My Home? 

With all that is said above, the answer is yes. SPF insulation is very safe for the home as it is less toxic than most chemical materials. It lasts longer and is very efficient in saving energy, preventing mold while also keeping bugs and rodents at bay. 

How Spray Foam Insulation Works 

From a distance, the spray foam insulation process may seem like a straightforward process. It begins with removing any existing insulation applications. This step is skipped when working with a new house or building. 

A hose is then used to spray all applicable surfaces with the liquid foam. The material then expands and solidifies, and once the job is done, the only thing left to do is to clean up. But of course, it’s always easier said than done. Just because the whole process sounds simple on paper, it doesn’t mean that you can hire practically any contractor for the job. It’s still essential to check on your contractor’s qualifications. Check if they carry a spray foam certification. 

What Is The Average Price For Spray Foam Insulation? 

Let’s cut to the chase: spray foam insulation is not the most affordable option out there. It is about two times more expensive than other materials like fiberglass or cellulose. 

But here’s the thing: spray foam insulation can significantly cut down your energy expenses more efficiently than the other options. Additionally, repairs and renewals are easier with spray foam. So, how much can you expect to pay for a spray foam insulation application? 

The price can be between $1.50 to $4.90 per square foot for both open-cell and closed-cell foam. Again, keep in mind that these prices do not include factors such as labor or other costs that may be specific to your construction project. 

Is There A DIY Spray Foam Insulation? 

As we mentioned, spray foam insulation isn’t the cheapest, but it is an ideal type of insulation. So, can you do spray foam insulation yourself? 

The short answer is yes. Most hardware shops offer DIY spray foam insulation kits that you can use for simple projects. However, we do not recommend that you do this independently, especially if you do not have experience or consider yourself a handy person.  

Before applying spray foam insulation, it is essential first to remove the drywall. And for anyone who has had experience in this, they know how taxing and messy this job can be. Unless you are confident with your technical skills, we suggest talking to a spray foam specialist and enlisting their help instead of doing DIY. 

Conclusion: Is Spray Foam Insulation For You? 

So, the moment of truth: should you opt for spray foam insulation? As we always say, the choice is ultimately up to you. Reassess the needs of your project. 

Do you need a solution that does not deteriorate over time? Are you interested in cutting down expenses over time, even if it means paying a more expensive upfront cost? If you answered yes, then definitely, spray foam roofing may be a viable option. However, if you’re thinking price over quality, then perhaps moving on to other materials may be the best solution for now.
