Insulation made of cellulose beats other types, keeping homes cooler in the summer and warmer in the winter. It’s also a safer option for both you and the environment.


The following are the top things about cellulose insulation you probably didn’t know about

  1. R-value per inch is a measurement of insulation. R stands for heat flow resistance, and the greater the value, the better the insulation. When installed correctly, cellulose has an R-value of 3.5-4, which is greater than normal when compared to other materials.
  2. Cellulose insulation is a plant fiber, recycled paper insulation that is used to insulate, drought-proof, and decrease free noise in wall and roof cavities. It’s both environmentally and financially sustainable because it’s composed of recycled plant fibers.
  3. Cellulose insulation helps to keep moisture out of the air. Minerals in the insulation inhibit the growth of these creatures, extending the life of the building.
  4. Cellulose is excellent in blocking drafts and allowing ventilation. In comparison to foam insulation, it fully fills gaps and holes around irregular items such as wiring, plumbing, and structural materials in attics and walls. Cellulose insulation also helps to distribute moisture and preserve the building’s structures.
  5. Glass fiber glass makers claim an average of up to 50% recycled content, whereas cellulose contains 82%recycled content.

These are just a few of the numerous benefits of cellulose insulation. Cellulose insulation is an excellent, environmentally friendly insulating material. It works better and uses less energy density.

Existing homes and new ones can both benefit from cellulose insulation. It can be blown as loose-fill insulation in attic cavities, densely packed into walls and floors, or wet sprayed into new construction to improve heat retention and noise reduction.

Dense pack cellulose is becoming more popular for retrofit insulation. The tight packing in the cavity walls provides thermal insulation as well as some soundproofing.

Water is added to wet-applied spray cellulose during the application process. the material has the same thermal and sound retardant qualities as dense packing. In new construction, wet spray cellulose is nearly typically sprayed before the drywall is installed.
