Problems We’re Solving
Wall Insulation
RetroFoam injection foam insulation 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 fill a space and the way it molds itself around any obstacle. RetroFoam is the perfect choice for any project that has an enclosed wall, floor or ceiling cavity that needs to get injected with insulation.
Many Minnesota homeowners are looking for ways to make their home comfortable and don’t realize that injectable, non-expanding wall foam insulation is even an option. Most folks think that they have to tear all of the walls apart to re-insulate, or the only foam available is the kind that expands out of the can and would blow the wall apart. The reality is that is not true, RetroFoam can be easily injected from e the outside by removing one course of siding around the whole house. RetroFoam is a totally unique type of foam that does Non expanding biodegradable, fire resistant and hypoallergenic which makes it safe for the whole family.
Attic Insulation
Proper attic insulation is one of the most effective ways to improve comfort, reduce energy bills, and protect your home from ice dams and extreme temperature swings. At RetroGreen Energy, we specialize in attic insulation solutions designed for long-term performance and energy efficiency.
Our attic insulation process starts with professional air sealing using high-performance spray foam. This step is critical to stop air leaks that drive up heating and cooling costs. Once the attic is properly sealed, we install cellulose insulation to meet or exceed recommended R-value levels for Minnesota’s climate. The combination of air sealing and cellulose provides maximum thermal performance and year-round comfort.
We use NCFI spray foam, one of the safest options on the market. It is formulated with Honeywell’s Solstice® blowing agents, which are non-ozone depleting and environmentally responsible.
