Cellulose Insulation - Part 3

Cellulose insulation is commonly blown or sprayed into attic spaces utilizing purpose-built equipment at depths between eight to fourteen inches. This equipment breaks apart the cellulose insulation, typically available in a compressed bale form, in a receiving hopper and utilizes a pneumatic blower to convey the material from the hopper through a length of tubing. The cellulose insulation is then discharged from this tubing into the space requiring insulation. This equipment is available to commercial applicators and it can even be rented by homeowners through many home improvement stores found in nearly any city within the United States. Many attics of residential buildings contain tight or confined spaces, can be very hot in summer months and provide minimal ventilation. Combine these attic characteristics with a significant amount of dust produced during the cellulose insulation application process and the task of installing a seemingly simple product becomes difficult and dirty. As such, safeguards are necessary to prevent the blown-in insulation from being deposited in areas where it is not supposed to be.
