Comfort, Energy Savings, and Improved Indoor Air Quality...Guaranteed

RetroGreen Energy is Minnesota's specialty insulation contractor. We focus on using high performance insulation and building science to improve home performance and energy efficiency. Our work encompasses all types of existing buildings including residential, multi-unit residential, agricultural, industrial and commercial buildings.

As an independent family owned business, we take pride in our work, reputation and relationships. By offering only the highest quality home performance solutions, we can GUARANTEE improved comfort and lower utility bills.

Our process involves retrofitting existing buildings with an insulation system that keeps 72 degree air inside, and Mother Nature’s air outside. We do this with energy auditing, RetroFoam injected insulation, spray foam insulation, blown cellulose insulation, Indow Windows and other services.

Your house will be worth more and easier to sell if you Retro Fit Today!

Many people put off making energy efficiency upgrades because they want to pass the buck to the next guy... how foolish. According to the appraisers journal for every 1 dollar saved per year in energy projects you will gain $20 dollars in the value of the house. Ie. $ 500 annual savings= $10,000 increased property value and yes your house will be easier to sell now because it is more comfortable and safer than the rest of the market.

For Consumers, Community & Earth

We are valuable to consumers by providing an opportunity to save money on energy and improve indoor thermal comfort, with numerous other benefits.

We are valuable to the community through our participation in community organizations and also as a comfortable and rewarding workplace for our employees.

We are valuable to Earth by improving home and building efficiency and durability, which conserves fossil fuels and other resources.

Spray Foam

Spray foam does what other insulation materials can't. It's a real problem-solver. Homeowners benefit from this product's very high R-value, its ability to bond directly to bare wood and the way it molds itself around any obstacle. Spray foam is the perfect choice for any project that has an open wall, floor or ceiling cavity.

Attics and Crawlspaces

A complete thermal envelope separates every conditioned interior space of your home from outdoor and unconditioned spaces (such as your crawlspace and attic) with a layer of insulation. Every thermal envelope is different. RetroGreen Energy assigns a BPI-certified professional to design and define the ideal thermal envelope for every home.
