RetroFoam Wall Insulation in Minnetonka

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

Minnetonka homeowners face unique comfort challenges. Large homes around Lake Minnetonka often suffer from drafts, uneven room temperatures, and higher than average energy bills. With long Minnesota winters and hot, humid summers, it can feel like you are always adjusting the thermostat. RetroGreen Energy provides RetroFoam injection wall insulation for existing homes, helping you achieve more consistent comfort without tearing apart your walls.

Why Wall Insulation Matters in Minnetonka

When walls are poorly insulated, heated air escapes in the winter while hot summer air seeps in. That forces furnaces and air conditioners to work overtime, which drives up energy costs and leaves rooms feeling uncomfortable. This is especially common in larger homes and lake properties with older construction. RetroFoam fills hidden gaps in wall cavities to create a seamless thermal barrier, helping you stay comfortable all year long.

A Retrofit Solution Without the Mess

With RetroFoam, we can insulate existing walls without removing drywall or remodeling. Our crews access wall cavities through small holes behind siding or through neat interior points if needed. The foam is the consistency of shaving cream when applied, so it flows around wires, outlets, and plumbing. Once it cures, it provides a lasting insulation layer that improves comfort, reduces drafts, and adds sound control. We patch and clean thoroughly so your home looks as it did before installation.

Unlike fiberglass or cellulose, RetroFoam does not settle over time. It remains effective for the life of the home.

How RetroFoam Works

Our crews mix the injection foam on-site using water-based resin, foaming agent, and compressed air. The mixture is pumped directly into wall cavities through small access points. After the foam sets, we plug the holes and replace siding or trim. The result is hidden insulation that adds strength and rigidity to walls without altering the look of your home.
