busy office space soundproofing

Especially if you live or work in a city, you know how distracting and irritating the sounds of some properties can be. Neighbors, animals, nearby lawn mowers, garbage trucks – it all can be very distracting. Especially for businesses with mechanical functions, even noises coming from another room can disturb a business’s workflow.

There is a solution to help reduce the rumbling noise, and we can help. If you’re looking to sound dampen an entire floor, building, or just one space, one of the most effective measures is RetroFoam.

How Does it Work?

When you think of sound dampening, you might think of the foam padding that we see in movies inside a recording studio. While that might be effective in those circumstances, walls covered in egg create shaped foam might not be the best solution.

Installation

RetroFoam Insulation is a noise deadening insulation. Installation is much less messy and time-consuming than other forms of blown-in insulation. Retro foam does not expand and will not settle. We simply create small openings and inject the foam insulation. The project can be done quickly without wreaking havoc on your business or home; there is no need to remove any existing insulation or to open up any walls, floors, or ceilings.

In addition to sound dampening, RetroFoam Insulation has other great benefits:

  • Keeping your space cooler in the summer and warmer in the winter
  • Making your building more energy efficient
  • Helping you save on your air conditioning and heating bills
  • Potentially extending the lifespan of your HVAC systems

At RetroGreen, we believe that RetroFoam Insulation is the best solution for sound dampening, but if you disagree, we will work with you to find the best solution for your business or home. If you are interested in sound dampening solutions, contact the RetroGreen Energy team to make your space more comfortable and peaceful.

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 He saw firsthand that most comfort and energy problems weren't caused by old windows or outdated furnaces — they were caused by air leakage and inadequate insulation that nobody was diagnosing properly.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.
