For those who have lived in Minnesota for even a short period of time, it’s no secret that our state is subject to temperature and weather extremes. Twin Cities residents owe it to themselves to do whatever possible in order to keep indoor temperatures consistent no matter how warm or cold it gets outside, and it all starts with having proper insulation in your home.
Did you know that as many as 90% of U.S. homes are under-insulated? It’s a statistic that seems like it would be an exaggeration, yet it’s not—at all. The vast majority of homes in Minnesota and the rest of the country lack proper insulation, which leads to a lack of indoor comfort, higher energy bills and a host of other home performance and energy efficiency issues.
Thermal insulation is a general term for any materials (such as spray foam insulation) that are specifically designed to reduce heat or cold air loss, providing a barrier that keeps indoor temperatures from shifting and outside air from affecting them. There are a number of different types of insulation available and countless areas of the home that can benefit from boosted insulation, such as the attic, basement, knee walls and more.
Insulation is often thought of as being necessary for the winter months of the year, but many people don’t realize just how important it is during the spring and summer as well. Because it keeps conditioned air from escaping, insulation is important throughout the entire year—not just when it’s cold outside.
For those who are looking to boost overall home performance, there’s simply no better way to get started than to schedule a home energy audit and to take a close look at your home’s envelope and insulation. There are a number of benefits that come along with properly insulating a home. These include:

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 He saw firsthand that most comfort and energy problems weren't caused by old windows or outdated furnaces — they were caused by air leakage and inadequate insulation that nobody was diagnosing properly.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