About Airseal Insulation Inc.

Air Seal Insulation and Spray Foam Insulation

Since 2002, Airseal Insulation Inc. has been coating long-lasting, eco-friendly spray foam insulation to residential homes and commercial buildings in Inland Empire. Spray foam insulation instantly fascinated owner, Bob Backman, when he first saw it being used in 1972. Five years later, when building a waterfront custom home, an architect failed to leave out enough glass to allow sufficient wall shear. This blunder fueled even more interest in Bob for the alternative insulation method. He recommended spray foam insulation for the shear and it worked! In the 90s, Bob began to investigate insulation more actively by attending seminars, reading, and asking questions. Spray Foam kept surfacing as a major contributor. Soon after, Airseal Insulation Inc. took off and became an industry leader in the application of spray foam for residential and commercial projects.

With over 40 years of industry related experience, Bob and his wife, Rhonda Backman, are dedicated to customer satisfaction. Their highly trained and certified crew shares the same passion about innovative business technology. The team understands that their customers are the backbone of the business. They are happy to take the time to get to know their clientele and are excited to share the energy and cost saving benefits of spray foam insulation.
