active water leaks, fuel leaks (i.e., gas, oil, propane), and pest intrusions

improperly terminated devices (ventilation fans, dryers, plumbing stacks, condensate lines, combustion appliance flues/chimneys, etc.)

unshielded high-temperature devices (non-IC rated recessed lights, chimneys, flues, vents, etc.) unless they are zero clearance devices

Verify that installation area is:

intact, able to support insulation weight and pressure, and air sealed

Select fiberglass insulation that has a flame spread and smoke development index of 25/450 or less when tested in accordance with ASTM E84 or UL 723

Remove objects from the interior surfaces of the walls being insulated

Repair or reattach interior paneling as necessary

Remove skirting if it overlaps the siding

Remove fasteners from the bottom of the siding, working upward until the siding can be pulled away from the framing approximately 6" without damaging the siding

Install temporary fasteners at the seams near the bottom of the siding panels to prevent separation

Cut access through sheathing if present

Install insulation in entirety of each cavity to a density of no more than 1.6 pounds per cubic foot between the interior paneling and any existing insulation

Do not overfill any portion of the cavity

Patch or repair sub sheathing as necessary

If skirting was removed, reinstall it to shed water to the outside of the skirting

Reattach siding with new fasteners and without bulges or wrinkles

Post a dated receipt signed by the installer that minimally includes: Installed insulation type, coverage area, installed thickness, minimum settled thickness, installed R-value, and number of bags installed
