How to install insulation yourself

There are two techniques that can be used to install cellulose insulation: Dry (or blown-in) and moisture-added. The moisture-added technique requires special equipment and can only be done by trained installers.

Cellulose insulation is applied using a blowing machine that is available for rent at most big-box stores, specialty lumberyards and many tool rental centers. This blower can often be rented at no charge when purchasing the cellulose insulation from the same store, so be sure to check.

Two people are required to run the equipment, which is made up of two parts, a blowing machine and a hose. One person feeds dry fiber into the blowing machine, which features a holding tank for the cellulose. The other person operates a hose that is extended to the location where the insulation will be deposited.

The blowing machine can be located inside or outside the house depending on which is most convenient to the area to be insulated. Follow the directions on the equipment to adjust the ratio of air to fiber to get the right mix and to ensure complete insulation coverage.
