cellulose INSULATION
Another insulation technique we utilize at Spray-Tech Foam is cellulose, or blown-in, thermal insulation. Made from recovered newspaper, the recycled product is a popular choice with our environmentally conscious customers. Cellulose insulation is one of the greenest building products in the world. If all the paper currently being put into landfills each year were converted to cellulose insulation, it would save approximately eight million tons of CO2 emissions.
From both health and environmental perspectives, cellulose is considered a "green" product and its' more ecologically sound than competing products. It doesn't contain formaldehyde and unlike Fiberglass cancer warnings are not required on its labeling. Since there are no glass fibers, as with fiberglass insulation, cellulose does not cause itch. Cellulose Insulation is made of 80% post-consumer recycled newsprint. The fiber is chemically treated with non-toxic borate compounds to resist fire, insects, and mold.
Cellulose Insulation may be used in walls and attics of residential or commercial structures. It may be used in cathedral or flat ceilings, crawl spaces, basements and as insulation under floors. Cellulose Insulation may be blown in horizontal applications such as attics and in retrofit wall applications of residential or commercial structures.
Seamless Protection
Unlike common batt insulations, Cellulose Insulation is sprayed into walls, cavities and attics, creating a continuous blanket of protection from energy leaks. This blanket enhances the energy efficiency of your home.
Studies of actual buildings show that cellulose insulated buildings use as much as 26% less energy than similar buildings insulated with typically installed fiberglass at the same R-value. One reason for this is the ability of cellulose to reduce air infiltration.
Uncontrolled air leakage through exterior walls and ceilings is almost as important as R-value in determining how much energy will be required to heat and cool a building.
Some facts about cellulose:
- Cellulose insulation manufactured from recycled paper is the least polluting insulation.
- Cellulose has the highest post-consumer recycled content. The fiberglass industry averages 35% recycled glass, while the cellulose industry averages a minimum of 75% recycled content.
- It takes 10 times more energy to produce fiberglass insulation than cellulose insulation.
- Due to air circulation and natural convection, the R-value of blown-in fiberglass insulation decreases by as much as 50% as the temperature drops from 45 degrees F to 18 degrees F.
- Cellulose Insulation provides up to 55% better fire resistance than glass by greatly restricting the flow of oxygen which can reach a fire and by being one of the few building materials which is treated with fire retardants.
