Drill & Fill Insulation Process:
- Depending on your home, drilling will either be from the inside or outside of the house.
- One- to two-inch-diameter holes are drilled into each bay.
- One installer operates the hose to fill each hole while a second installer operates the blowing machine.
- The two installers use cellulose insulation to fill each bay of a wall, providing maximum insulation.
- After all holes and bays are filled with cellulose insulation, each hole is patched up.
