Insulation Installation

 

Cellulose insulation is installed by one of two techniques. Dry blown (loose-fill or dense pack) and spray applied (moisture-added.) Dry blown is an option for homeowners interested in a do-it-yourself (DIY) cellulose insulation installation. The moisture-added technique requires special equipment and can only be done by trained installers.

Dry blown cellulose insulation can be installed using a blowing machine that is available for rent at most home improvement 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.

It is important to properly prepare the area for insulating prior to beginning installation. This critical step can typically be done as a homeowner DIY project. Learn more on the CIMA Blog.

Once the area is properly prepared a team of at least two people are required to install cellulose insulation. The equipment includes a blowing machine and a hose. One person feeds dry cellulose insulation fiber into the blowing machine. The other person operates a hose that is extended to the location where the insulation will be deposited. This person blows in the cellulose to fully cover the area to the recommended depth found on the cellulose insulation packaging.

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.

Keep in mind the performance and potential energy savings are dependent on properly installing the insulation. Homeowners thinking of using cellulose insulation as a DIY project, but who are not fully confident in the technique of installing cellulose insulation, should consider hiring a professional insulation contractor experienced with installation of cellulose.
