Cathedral Ceilings

Fiberglass insulation is meant for square homes with square walls — but it just can’t fit into spaces with unconventional angles. Take cathedral ceilings for example: with plenty of sharp angles that all meet at a singular point, it would take a fiberglass insulation artist to to get a tight fit that’s leak-proof and sturdy.

With spray foam insulation, you get an airtight and watertight seal. Spray foam enters and expands in awkward corners and crevices, meaning there’s no space between your outer structure and your insulation, This can increase your energy efficiency and prevent water and critters from setting up shop.      


Your attic can make or break your home’s energy efficiency. Without proper insulation, you could be spending up to 40 percent more on your energy bill each and every month! Spray foam insulation creates an impermeable barrier between your roof and your attic — it not only keeps moisture out, but it can lower your monthly energy bill by 20 percent compared to traditional fiberglass insulation. It fits perfectly into attic hatches, wiring holes, behind knee walls, and around plumbing vents, which means you’ll minimize air leaks in the most hard-to-reach places.

Media Rooms & Home Theaters

Spray foam insulation doesn’t just work as an air sealant and water sealant — it dampens airborne sound transmission as well. The less air you have flowing in from the outside, the quieter your room will be — and that’s the difference that will improve your surround sound audio quality and bring out the details in your media experience. Plus, you’ll be able to turn the volume way up during your favorite action movies while your significant other reads peacefully in another room.


Crawlspaces are the last place people consider spray foam insulation. However, it’s the place where spray foam insulation can do the most good. Even the sturdiest foundation cement can let moisture through, which can create widespread moisture buildup that breeds toxic mold. All that moisture can create a nice home for critters, too.

Sealing up your crawl space with spray foam insulation will keep moisture out, which can extend the life of your home and prevent a variety of mold-related ailments. It’s well worth the investment for your home and your health.

Home Additions

If you’re adding a new family room or master bedroom to your home, you’re going to need insulation of some sort. Why not choose spray foam? It might cost slightly more upfront for closed-cell spray foam insulation than traditional fiberglass insulation, but you’ll reap the energy energy savings and have fewer headaches down the road.

With spray foam insulation, your new room with have exceptional temperature control, protection for moisture intrusion, and a higher value overall — it’s an excellent investment for those who want to sell their homes and those who are looking to stay for years to come.


Your basement is an ideal place for spray foam insulation — especially if you’ve become accustomed to uncomfortably hot or cold temperatures, or if your basement is prone to flooding. If this sounds like your basement, then your basement isn’t as well-insulated as it should be. Poor temperature regulation is a sign that fiberglass insulation isn’t getting the job done. Basement flooding, on the other hand, is a sign that your fiberglass insulation is soaking up moisture, which can be the start of structural damage or mold intrusion.

Closed-cell spray foam insulation acts as an air barrier that can prevent air drafts and reduce your energy costs. Plus, the Federal Emergency Management Agency (FEMA) classifies closed-cell spray foam insulation as a flood-resistant material. Because of this, closed-cell spray foam insulation is excellent for homes in areas with lots of precipitation or hurricane risk, like the South, Mid-Atlantic, Pacific Northwest, and even areas of the Rocky Mountain Region that get a lot of snow.
