Tips & Warnings
Blowing in insulation is two-person job. You need someone to monitor the blower outside and someone inside to fill the wall cavities.
Always wear a dust mask when blowing in insulation. Breathing the dust from the insulation poses health risks because the insulation contains chemicals to prevent bugs and to make fire retardant.
Blown-in insulation is not recommend for walls that don't contain a moisture barrier. Using it can cause constant moisture in the walls, leading to rotting sills and paint problems and it can attract bugs into your walls.
