Local Minneapolis Insulation Contractor

Stay Warm in the Winter & Cool in the Summer

Minneapolis homeowners know the struggle—harsh winters and humid summers make indoor comfort a challenge. If your home has poor insulation, you’re likely losing heat in the winter and overworking your AC in the summer. RetroGreen Energy’s RetroFoam injection insulation seals your walls without tearing them open, keeping your home comfortable, efficient, and quiet year-round.

Why Insulating Your Walls Matters

Without proper insulation, heat escapes in the winter, and summer heat seeps in, making your HVAC system work overtime. This means higher energy bills and an uncomfortable home. RetroFoam fills every gap in your walls, creating a continuous thermal barrier that keeps you cozy in the winter and cool in the summer—without the drafts and energy waste.

Insulation Without the Mess

Worried about damage? No need. RetroFoam is injected through small access points, so there’s no need for major renovations. Here’s how it works:

Injected as a soft foam (like shaving cream) that fills every cavity.
Doesn’t expand, so it won’t damage your walls.
Works with all home exteriors—vinyl, wood, stucco, even concrete block.
Minimal disruption—we remove a strip of siding or drill small holes, then seal them seamlessly.

The RetroFoam Advantage

Energy savings – Stop heat loss and reduce utility bills.
No settling – Unlike fiberglass or cellulose, RetroFoam stays put.
Fire-resistant & non-toxic – Safe for your home and family.
Noise reduction – Blocks outdoor noise for a quieter home.
Fast installation – Most homes are done in a single day!

How Does RetroFoam Work?

It’s all about the application. RetroFoam is a water-based, non-expanding foam that we mix on-site and inject into your walls. It fills every crevice, then cures into a solid, airtight barrier. Unlike other insulation methods, it won’t sag, settle, or break down over time.
