Spray Foam Insulation: Clean, safe and effective.

What exactly is spray foam insulation? Spray polyurethane foam (SPF) is an innovative foam plastic substance that is sprayed onto an open surface in paint-like form and then expands to create an insulating barrier against wind and outside temperatures.

What does spray foam insulation do?

It helps ensure that the conditioned air created by your heating, ventilation, and air conditioning system (HVAC) stays inside. In this way, it helps you save thousands of energy dollars while also protecting the environment. It also protects your home from condensation and water. It keeps cold air out in winter and hot air out in summer. In addition to providing excellent insulation, spray polyurethane foam acts as several products including:

  • Sealant
  • Air barrier
  • Vapor retardant
  • Weather barrier

Where is spray foam insulation used?

  • Insulation in walls, attic spaces, ceilings, and basements
  • Industrial insulation for cold storage spaces, walk-in refrigerators / freezers, produce storage rooms, pipes, tanks, and more

Benefits of Spray Foam Insulation


Spray foam insulation works for all exposed surfaces including walls, ceilings, basements, crawl spaces, and attics.

Structural Value

Spray foam insulation adds to the structural integrity of your home.

High R-Value

The higher the R-Value, the more resistant a material is thermal exchange. Spray polyurethane foam insulation has a very high R-Value.

Multi-Level Barrier

Spray foam insulation serves as an air barrier as well as a sound barrier.

Moisture Reduction

Condensation and moisture can cause mold growth and water damage, which spray foam insulation protects against.

"We're glad we decided to go with USA Insulation to have our house insulated better. As of today I can't say I'm seeing a difference in the temp in the house but to be fair I've not been home much. We are more interested in what the difference will be this heating season with having the house done. We'll have that answer in a few months. As for the companies personnel I can say this, the team that was out here were very knowledgeable, personable and friendly. They answered every question I asked without hesitation. I have to say I would highly recommend folks look into this process getting their homes evaluated and insulated though USA."

"We got a great price from Matt and the crew was great. Our 1771 house threw us a curve midstream but we worked together to solve the issue. Altogether a great experience. Looking forward to increased comfort this winter!"

"I have owned a 1788 Cape house for 6 years. I’ve been cold for 6 years. The new windows and front door helped a little. But the USA Insulation of Southern NH has made the biggest difference. Their process is great. Everything was communicated to me in word I could understand. The men were amazing. Darren took care of everything in a very professional way. Thank you so much!!!"
