Diy Damp Spray Cellulose Insulation

Both varieties are composed of recycled newsprint with chemical additives.

Diy damp spray cellulose insulation.

Compared to spray foam installing damp spray cellulose is a comparatively low tech operation. Blown in cellulose has a higher r rating and is less expensive than either blown insulation like fiberglass attic insulation or fiberglass batts. The moisture added technique requires special equipment and can only be done by trained installers. This is damp spray.

Dry fiber that is blown into open attics and enclosed cavities and damp fiber that is sprayed into open wall cavities. Cellulose insulation comes in two varieties. Cellulose blown in ceiling insulation is a good choice for diyers. This is slightly different from another type of cellulose insulation which is designed to be blown onto open walls much like spray foam.

This studyconducted by the canadian housing information centre on wet sprayed cellulose insulation in wood frame construction found the framing material can have the moisture content more than double and that it may take as long as five monthsto get the framing back to pre installation levels.

Cellulose insulation is installed by one of two techniques. Basically cellulose recycled newspaper runs through a flexible hose under air pressure and mixes with high pressure water added at the blowing nozzle.
