How Do I Install Blown-In Attic Insulation?

Blown-in attic insulation is installed by professionals who are trained in the proper procedures for this installation. The insulation is made up of a two-chemical soup that instantly forms a material called urea-formaldehyde. The installation crew will start by removing the old insulation. They will then place a new vapor barrier in place. That done, the crew will seal the area and insert a dual-hose system involving a generator and a pump. This sprays the insulating material that expands to fill the existing space and then hardens instantly.
