The Wall Insulation Process using cellulose:
First I inspect the opposite side of the walls to be insulated. I remove any objects that could fall due to vibration. Any holes or gaps are sealed to prevent the insulation from coming through. One inch holes are drilled in each cavity in the wall.
Typically there will be a line of holes 16" apart across the top of the wall and below the fire block which runs across the middle of the wall. I find all the vertical and horizontal wood studs in the wall with a long wire. This shows me exactly where each hole needs to be drilled. Cellulose insulation is blown in under air pressure to completely fill the empty cavity. I then patch the holes using the appropriate material for the surface drilled through.Stucco:
A hard, non shrinking stucco patch floated on with a rubber trowel to match the texture of the wall.Wood:
A plug is set into hole and a non-shrinking spackle patch is applied with a tape knife.Drywall:
The hole is carved around the edges to remove any rough burrs then a plug is set and non-shrinking spackle applied with a tape knife.
After the patch has cured and you have primed and painted the area there will be no visible clue the wall has been drilled. Finally the areas worked on are vacuumed, swept or washed down. It is recommended that insulation of interior or exterior walls be completed before you paint your home.
