Drill & Fill Insulation
Energy-efficient retrofit insulation for existing walls , improving comfort and reducing energy loss without major renovation.
Retrofit Insulation for Existing Walls
Many homes were built with little or no insulation inside the wall cavities, allowing conditioned air to escape year-round. Drill and fill insulation is a practical retrofit solution that improves energy efficiency by filling those hidden wall spaces without removing drywall or siding.
Crescent Moon Insulation uses the drill and fill method to upgrade wall insulation in finished homes. This process helps keep warm air inside during Minnesota winters and cooled air inside during summer, resulting in more consistent indoor temperatures and lower energy costs.
Drill and fill insulation is ideal for older homes or any structure where traditional wall insulation upgrades would be disruptive or cost-prohibitive.
Scalable Solutions
Effective for single rooms, full homes, and retrofit projects of all sizes.
Dense-Pack Coverage
Dense-pack cellulose insulation designed for full cavity coverage.
Energy Cost Reduction
Helps lower heating and cooling costs by reducing air leakage inside wall cavities.
Minimal Disruption
Installed without removing drywall or major interior finishes.
Energy Efficiency Starts Inside the Walls
In Minnesota's climate, uninsulated or under-insulated walls are a major source of heat loss. Drill and fill insulation improves thermal performance by sealing gaps inside wall cavities, reducing air movement and preventing energy waste.
By upgrading wall insulation, homeowners can reduce strain on heating and cooling systems, improve overall comfort, and protect their home from temperature fluctuations common in extreme seasonal conditions.
