Why RetroGreen Offers Spray Foam Insulation

Insulation is key to an energy efficient home. By adding a layer of protection against outdoor air, spray foam is one of the highest-performing insulation options available. For homeowners in the Saint Cloud area, RetroGreen Energy is here to help you make a strategic upgrade with spray foam insulation.

What is Spray Foam Insulation?

Spray foam insulation is a spray-applied plastic that forms a barrier around key areas in your home. A very efficient choice for home insulation, spray foam seals up your home’s perimeter, or “building envelope.” This means that your home’s conditioned (aka heated or cooled) air is more effectively kept inside.

Spray foam insulation has the unique ability to bond directly to wood and mold itself around any obstacle, making it an optimal choice for any project that has an open wall, floor, or ceiling cavity.

Benefits of Spray Foam Insulation for My Minnesota Home:

Spray foam is one of the highest performing insulations of any on the market. Since it works so effectively for tightening the building envelope, there is a reduced strain on heating and cooling systems. They don’t need to work overtime to compensate for a leaky building, so you don’t need to run them as often–this means significant energy savings of 15-50% on annual energy costs!

There are a number of additional benefits of spray foam insulation, including:


  • Instantly improved home comfort

  • Maximum R-value for supreme efficiency

  • Minimized dust and pollen infiltration

  • Reduced noise, ice damages, and the likelihood of mold

  • Mitigated air and moisture infiltration — creating a more consistent temperature

  • Stable performance over time — will not sag!

Owner & Founder

Chris didn't start RetroGreen Energy because he wanted to be in the insulation business. He started it because he wanted to fix homes the right way.

After earning his BPI Building Analyst certification and Minnesota Building Contractor license, Chris spent years studying how homes perform as systems. He saw firsthand that most comfort and energy problems weren't caused by old windows or outdated furnaces — they were caused by air leakage and inadequate insulation that nobody was diagnosing properly.

In 2009, he launched RetroGreen Energy with a commitment to doing things differently. Every project would start with proper diagnostics. Every recommendation would be based on data, not sales targets. And every homeowner would get the honest truth about what their home actually needed.
