Minneapolis Injection Wall Insulation

RetroFoam injection insulation is a game-changer in retrofit insulation for existing homes.

Minneapolis homeowners face unique challenges when it comes to maintaining comfortable indoor temperatures throughout the year. With the extreme cold of winter and the hot, humid summers, effective insulation is essential for energy efficiency and comfort. RetroGreen Energy offers cutting-edge injected wall insulation, using RetroFoam, to ensure your Minneapolis home stays warm in the winter and cool in the summer.

Why Wall Insulation Matters in Minneapolis

In Minneapolis, inadequate insulation can lead to significant heat loss during the winter months, driving up your heating bills and leaving your home feeling cold and drafty. Similarly, in the summer, poor insulation allows hot air to infiltrate your home, forcing your air conditioner to work harder and increasing your energy costs. RetroGreen Energy’s injected wall insulation provides a seamless barrier that prevents these issues, keeping your home comfortable year-round.

With RetroFoam, we can fully insulate your walls without having to tear your house apart.

RetroFoam is designed to be injected into the wall cavities of existing homes. As it is being injected, it is the consistency of shaving cream so it fills every corner of the cavity and around plumbing and electrical work. After the foam cures wires can still be pushed through the foam in electrical lines need to be fished down a wall. RetroFoam can be installed by simply removing one course of siding whether its steel, vinyl, wood lap or even half log siding. For other types of exterior cladding such as stucco or concrete block, 5/8” holes are used to access the stud cavities. Even paneled siding that is not removed can be drilled through and coved with trim to make the plugs disappear.

Benefits of RetroFoam insulation

  • High thermal resistance (R-value) insulation which provides comfort and energy efficiency
  • Non-expanding material (not like the canned stuff), making sure your walls aren’t blown out!
  • Completely non-toxic and fireproof keeping you healthy and safe
  • Reduces noise and dampens sound, so you can enjoy the peace and quiet
  • Perfect for retrofitting and re-insulation, since it doesn’t require walls to be opened up
  • Complete installation in your home in just one day!

Unlike blown-in cellulose or fiberglass insulation, RetroFoam will not settle over time. In addition to wall cavities, the material also works really well in concrete block foundations and cathedral ceilings.

This sounds like magic – how does injection foam insulation work?

The key to understanding this special product is how it’s mixed and applied. Our injection foam is a non-expanding composite of water-based resin, foaming agent and pressurized air. We mix it on-site and mechanically inject it into your home’s walls. The only steps we need to take to gain access to the insulation space are removing a strip of siding and drilling a series of small holes in the exterior wall. Once the injection foam is in place, we seamlessly plug the holes and replace the siding. Remember this is a non-expanding foam and will not blow out your walls.

Facts about RetroFoam insulation

  • It will not expand, lose shape, or lose effectiveness. What it will do is raise the structural durability of your home, adding strength and rigidity which will make it more durable over the years through extreme wind, rain, and snow. After insulation, RetroFoam is totally maintenance free and lasts for the life of the home.
  • Even if you already have insulation, RetroFoam can be easily applied with other insulation to provide a more effective insulation barrier. RetroFoam outperforms all other types of wall insulation, especially in extreme cold and wind. Fiberglass R-Values are based on laboratory conditions at 70 degrees with no heating or cooling load, not a real Minnesota climate. Also, unlike fiberglass insulation, RetroFoam is also water-, pest-, and fire-resistant.
  • RetroFoam insulation can be injected into the walls behind any type of exterior. RetroFoam isn’t just for homes with siding. We have retrofitted homes with masonry and stucco, patching the injection sites with no noticeable difference in color or texture. Some homeowners prefer we do our work from the inside, and that process is also simple, fast, and effective.
  • RetroFoam adds safety and value to your home because fires burn more slowly through RetroFoam-filled walls. RetroFoam foam insulation is a Class 1 nonflammable product. In the tragic event of a house fire, this extra time could be the difference between losing one or two walls and losing your whole house to a fire and could also give the extra time needed to get everyone out safely!
