How Does It Work?

The Science Behind Spray Foam Insulation

Spray foam insulation works by expanding upon application to fill gaps, cracks, and crevices, creating a complete thermal barrier that traditional insulation methods can’t achieve.This airtight barrier reduces drafts and minimizes the infiltration of allergens and pollutants, keeping you warmer in the winter and cooler in the summer.

Spray foam insulation is the best choice for new home construction, pole barns, and metal buildings. Similar to the foam in igloo coolers, spray foam maintains your desired indoor temperatures longer, reducing HVAC runtime and extending equipment lifespan. Plus, closed cell spray foam is Class 1 Fire-Rated for added safety and peace of mind.

Reduced Energy Bills

Spray foam insulation reduces energy loss by creating an airtight seal, helping you save up to 50% on your annual heating and cooling costs.

Comfortable Living Space

Spray foam prevents cold drafts from entering and maintains even temperatures in your home, ensuring a comfortable living environment all year long.

Better Noise Control

Our spray foam insulation services dampen outside noise from entering your home, creating a quiet living space that is ideal for peace and relaxation.

"Shawn with Gateway RetroFoam was great work with. He was prompt for the estimate appointment and the install. His crew did a great job and left the site clean and tidy. He explained everything thoroughly and the house feels snug and quiet now."
Ria S.
"Shawn was awesome to work with from initial request for information, to the quote and then the installation. He explained everything along the way. Installation was quick and painless, the crew all seemed to really know what they were doing. Already feel the difference in areas of the house that were previously drafty. Can’t wait to see the utility bill savings! Would highly recommend Retrofoam as a product and Gateway Retrofoam for anyone looking for better insulation of their home."
Andrew F.
"Shawn, the owner, and his crew were amazing. They were professional and respectful of our property, cleaning up as they worked and even helping to move some of our belongings. Despite our 30-year-old siding, you can’t tell where they removed and replaced it. Shawn explained everything in detail before and during the process, showing us how they checked the walls before filling them. Gateway Retrofoam is a low-pressure, very affordable company to do business with. We definitely made the right decision choosing them over USA Insulation."
Jeri B.
"Shawn and his crew at Gateway RetroFoam were awesome from start to finish. They arrived at 8:30 am and finished by 5 pm. Throughout the day, Shawn kept us informed about their progress and was very informative. At the end of the day, the crew cleaned up everything, and Shawn made sure we were satisfied. I would give Shawn and his crew five stars and highly recommend Gateway RetroFoam!"
Tom C.
"Shawn and his team were incredibly professional and made the whole process easy. Shawn was a no pressure salesman and gave us respect and comfort. We have already noticed a difference in two days. Thanks Shawn and team! I highly recommend considering this company for your future projects."
Angie A.
"Gateway RetroFoam LLC worked tirelessly, 8:30 AM to 3:00 PM, insulating our villa’s exterior walls. We will definitely keep an eye on the energy usage during the next year to measure improvement. Maggie looks forward to a warmer kitchen in winter, cooler in summer. They did a great job cleaning up during and after blowing in the insulation. Everyone working was pleasant, approachable, and knowledgable, answering any questions we had. Great job guys!"
