Most Hutchinson homes built during the 1920s-1970s industrial small city era have completely empty wall cavities behind their vinyl siding. These uninsulated walls are the single largest source of heat loss, allowing cold air to flow freely through the exterior envelope every time the wind blows. For Hutchinson homeowners, that translates to high heating bills, cold drafts near exterior walls, and rooms that never seem to reach a comfortable temperature.
RetroGreen Energy solves this with RetroFoam injection insulation — a tripolymer foam that we inject directly into the wall cavities through small holes drilled in the exterior. The foam expands to fill every gap, crack, and void, creating a complete thermal and air barrier without removing any siding or disturbing interior finishes. We work with vinyl, aluminum, wood clapboard — all siding types found on Hutchinson homes. Most wall insulation projects in Hutchinson are completed in a single day.
Hutchinson homeowners served by their local utility may qualify for rebates on wall insulation projects. We handle the rebate paperwork and offer 0% financing up to 60 months. Call (320) 252-8888 to schedule your free diagnostic assessment and see exactly where your walls are losing heat.
Key Benefits
Lower Energy Bills
RetroFoam's air seal stops conditioned air from escaping. Most homeowners see a 15-50% reduction in heating and cooling costs.
Consistent Room Temperatures
No more hot and cold spots. Every room maintains a comfortable temperature because the envelope is properly sealed.
Reduced Outdoor Noise
The dense foam acts as a sound barrier, significantly reducing traffic noise and other outdoor disturbances.
No Moisture or Mold Risk
RetroFoam doesn't absorb water and doesn't promote mold growth, unlike fiberglass which can trap moisture inside wall cavities.

Our Process in Hutchinson
Siding Removal and Preparation
We carefully remove a course of siding to expose the wall sheathing beneath. Each stud cavity is located and a small hole is drilled. Our technicians use a specialized tool to check for obstructions inside the wall before injection begins.
RetroFoam Injection
RetroFoam the resin is mixed in the truck, then injected into each wall cavity through the drilled holes. The foam flows to fill every gap, crack, and void — wrapping around wiring, plumbing, and any obstacles. Pressure gauges ensure complete fill without over-packing.
Seal, Replace, and Verify
All drill holes are plugged and sealed. Siding is carefully replaced to its original position. We perform a final inspection to verify complete coverage and ensure your home looks exactly as it did before.
