Drill & Fill Wall Insulation

Drill and fill refers to a method of insulating closed walls—for retrofit (re-insulation) projects, rather than new construction, where the walls are open. Small holes are drilled into the walls and the insulation is blown directly in.

Walls are significant sources of energy loss, so making sure they are properly insulated can help increase the energy efficiency of your home and save you money. In addition to this, insulating walls can help:

  • Make your home or building a more comfortable space
  • Improve the efficiency of your air conditioner and furnace
  • Reduce noises on different levels inside
  • Contribute to a healthier environment

The Gold Star Insulation team uses cellulose and fiberglass insulation for wall drill and fill projects.
