In St. Louis Park, where harsh winds compound already-cold temperatures, attic insulation is the most impactful single upgrade you can make. Most rambler homes in St. Louis Park from the 1940s-1960s post-war and early suburban era era have only R-19 to R-30 of attic insulation — far below the R-49 to R-60 recommended for this climate. That gap costs St. Louis Park homeowners hundreds of dollars in wasted heating every year.
RetroGreen's attic insulation process starts with thorough air sealing — we close every bypass that allows heated air to escape into the attic, including around light fixtures, plumbing stacks, bathroom fans, and attic hatches. This is especially critical in St. Louis Park, where ice dams form when heat escaping through the attic melts roof snow that refreezes at the eaves. Then we blow in insulation to reach the recommended R-49 to R-60, creating a uniform blanket across the entire attic floor.

Key Benefits
Dramatic Energy Savings
Sealing the attic envelope cuts heating and cooling costs by 20-40%. Most homeowners see the impact on their very first energy bill after installation.
Ice Dam Prevention
Spray foam keeps the roof deck at a consistent temperature, stopping the melt-freeze cycle that creates ice dams and causes costly water damage to gutters and interiors.
Comfortable Upper Floors
Rooms directly below the attic maintain a consistent temperature instead of swinging between extremes. No more space heaters in winter or window ACs in summer.
Moisture and Mold Protection
Closed-cell spray foam acts as a vapor barrier, preventing the condensation and moisture buildup that leads to mold growth and wood rot in attic framing.

Our Process in St. Louis Park
Attic Assessment and Air Sealing
We inspect your existing insulation, identify all air leaks, and seal every penetration — plumbing vents, electrical wires, can lights, chimney chases, and HVAC ductwork. This critical first step ensures the insulation performs as designed.
Spray Foam Application
Our certified technicians apply spray foam to achieve your target R-value. The foam expands to fill every gap, irregular space, and hard-to-reach area. Open-cell or closed-cell formulations are selected based on your attic configuration and goals.
Final Inspection and Cleanup
We verify complete coverage and proper thickness with measurement tools, check for any missed areas, and clean the work area thoroughly. You receive a summary of work completed and before/after photos.
