Spray Foam Insulation Details and Info

Not only is home insulation crucial for a comfortable Northern Illinois home, but insulation is an investment that can end up saving you thousands of dollars over the years. With that being said, it’s completely understandable to have questions—especially when it comes to spray foam insulation. What you will find below are some of the most common questions we receive from our customers who want to learn more about this service.


Q: How long does an average spray foam insulation job take?
A: Depending on the size of the job, it can take anywhere from 2 to 6 hours.

Q: Will spray foam insulation damage my roof?
A: No. This is a common misconception. CertainTeed ran a three-year study that found if applied correctly, no damage occurred to shingles, roofing, or deck materials. You can see the study here.

Q: How long is Paragon’s insulation efficient for?
A: Our insulation is built to be efficient for 20–30 years.

Q: Which is better, closed or open-cell spray foam insulation?
A: A quick answer to this question is that it simply depends. While you can definitely look at the differences between open-cell and closed-cell spray foam insulation, both have their pros and cons.

Q: How loud are the machines Paragon uses on the job?
A: They’re not much louder than the average riding lawn mower.

Q: How would the spray foam contractors power their tools?
A: Our professional spray foam insulation contractors bring their own source of power to each job site.

Q: Would I have to leave my house during the spray foam insulation process?
A: Yes, for your safety, we recommend leaving your house for 2–4 hours.

Q: What is the difference between Paragon and other insulation companies I can find on the internet?
A: What makes us different is that we are local. We not only work in the Chicagoland area, but we live here as well. So we know what you truly need when it comes to having comfortable insulation during the harsh weather we experience here in Northern Illinois. We use clean green environment insulation; better quality has better results.

Q: What is the difference between spray foam insulation and fiberglass insulation?
A: There are many differences between these two types of insulation. If you were to try to compare the cost of each, you would have to factor in short-term costs versus long-term costs, as spray foam costs more up front but holds up better over time than fiberglass does.

Q: Which is better, fiberglass insulation or cellulose insulation?
A: It’s difficult to say which is purely better than the other because it depends on what you are trying to accomplish. Both fiberglass insulation and cellulose insulation have their differences, so it’s a case-by-case basis regarding which is best for you.


Q: Is spray foam insulation eco-friendly?
A: Yes, the spray foam insulation that Paragon Protection uses is not only eco-friendly but also OSHA-approved. In fact, spray foam insulation is one of the most environmentally friendly types of insulation on the market today.

Q: Should I insulate my attic or insulate my basement?
A: Each area has benefits you’ll enjoy. Let’s look at it through this analogy. If it’s cold outside, do you wear socks or a hat? You need both, just like you need both areas of your home insulated. It also comes down to what you prefer.


          • Insulate your attic if your focus is to create an energy-efficient home.
          • Insulate your basement if your get a lot of mice and you have cold floors.
    Q: What are some of the materials used by Paragon Protection?

    A: We use several quality materials for our projects. For closed cell foam insulation, we use Heatlok HFO High Lift foam. For fiberglass insulation, we use PROPINK® L77 PINK® Fiberglas™ unbonded loosefill insulation. For cellulose, we use Champion cellulose fiber insulation.
