Looking for long-lasting, high R-value insulation that seals out moisture and strengthens your structure?
Our closed cell spray foam insulation is one of the most advanced, durable, and energy-efficient solutions available for homes and businesses across Pleasant Hill, IA—and beyond.
What It Is
Closed cell spray foam insulation is made of dense, gas-filled bubbles that expand and cure into a rigid material. This hardened structure not only insulates—it also reinforces your building’s frame for enhanced strength and durability.
With R-values up to R‑7 per inch, this high-performance foam significantly reduces air leakage and cuts noise by up to 50 decibels.
At depths of 1.5″ or more, it becomes a Class II vapor barrier, keeping out moisture and improving indoor air control. Other performance specs include:
This makes closed cell spray foam ideal for Iowa’s extreme temperatures and year-round humidity challenges.

The crew at AFI was outstanding! Work was completed in a professional and timely manner. Highly recommended!
This company is the best. Our home posed many challenges as it is 148 years old with additions of unknown ages. Mike K. and his team faced each challenge with grace and got the job done to perfection. Even with a 70 lb puppy, Milly bringing him toys all day. I highly recommend them!
The guys did a great job this morning with an extraction! Looking forward to calling them when we need to spray foam!
