Worried About Foam Insulation?



>

One of the first things that many people who are setting out to improve their home’s insulation discover is that there are a number of different materials from which to choose. Deciding on the right insulation material for your home can be challenging, especially considering the fact that each type of insulation has its own set of pros and cons. In such a case, the best route to take is to work with a professional home efficiency contractor who can help you on your quest to make the right decisions.

There are a lot of concerns among homeowners in the Minneapolis and St. Cloud areas about the perceived health dangers of foam insulation. The fact is, foam insulation is one of the most effective materials on the market, but it can be dangerous if installed improperly. At RetroGreen, our team of talented home performance experts has a strong handle on the finer points of home insulation, and we can ensure a safe, proper installation of foam insulation.

Why RetroGreen Chooses Foam Insulation

We take home health and efficiency seriously here at RetroGreen, which is why the decisions we make about which types of insulation to use are not made without a great deal of thought. Foam insulation is not only one of the most effective insulators on the market, it actually acts as both insulation and air sealing. For those who are experienced in working with it, applying spray foam is an efficient process and can be done from either inside or outside of the home.

One of the reasons that many people are concerned about foam insulation is the issue of off-gassing. The installation process can create hazardous fumes, which is why it’s so important for those who are handling the installation to wear personal protective gear the entire time. Once the foam has expanded and cured, it becomes chemically inert. If the spray mixture is not properly prepared, however, the chemicals may not react properly and could potentially remain toxic—just one more reason to hire a home performance contractor to do the job.

Let RetroGreen Put Your Fears to Rest!

The team at RetroGreen wants to put our customers’ minds at ease about any potential dangers related to spray foam insulation. We understand your concerns. Our team is here to answer any questions you may have about the material and its relation to the health and safety of your family.

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.
