Champion Cellulose Fiber Insulation


Blow-in insulation

Sidewalls, cathedral ceilings and other areas in new construction can be filled with cellulose insulation by using a fabric material to create an enclosed cavity between the studs. The fabric is stapled to the studs and the insulation is blow-in without moisture. The results are a completely filled cavity which provides outstanding performance.

Sprayed Cellulose (“moisture added”) insulation

In some new construction, cellulose insulation wall cavity spray is often used. This introduces water into the normal Cellulose insulation to make it damp and slightly gluey so it adheres to wall cavities. Call us about our specially designed insulation for this installation technique.

As the dry Cellulose insulation is blown out of the machine, it is covered with a fine mist of water. The water moistens the dry fibers making it stickier for better adherence to the wall cavity. The correct mixture of water to dry fiber is essential to not soak the wall cavity and yet provide enough moisture to ensure good adherence to the wall cavity.

The wall cavity is “overfilled” so some of the Cellulose insulation extends beyond the studs. The excess material is then scraped off using a “scrubber” (a rotating brush) which evens out the wall.

The moisture level of the insulation should be measured with a moisture reader to ensure that it is sufficiently dry before it is closed in with drywall. As this technique is normally used in new construction, it is normally performed by experienced installers. This minimizes the risk of getting the mix of water and dry fiber wrong and allowing proper drying time.
