Cellulose insulation batts

What are the health hazards of cellulose insulation? Which is better cellulose or fiberglass insulation? What is the difference between cellulose and fiberglass insulation? Who are the best cellulose insulation manufacturers?

Greenfiber All Borate Cellulose Blow-In Insulation lbs. For attics, cellulose insulation is blown in parallel to the joists. ECOCELL batts meet or exceed ASTM testing for both commercial and residential insulation. It can be used by itself to fill in joist cavities that have no insulation or laid as a thick layer over the top of existing batts of fiberglass insulation.

Types of fiberglass and cellulose insulation. There are two ways to get your insulation , whether fiberglass or cellulose : batts or loose fill. Sometimes, loose fill insulation is referred to as blown in insulation because an installer literally blows it into your home with a special machine. Nu-Wool Premium Cellulose Insulation is the base material in the majority of CMS products, giving them a performance edge over fiberglass and other shoddy materials. When comparing blown-in insulation , both fiberglass and cellulose are nearly identical in price, both costing around $0.

Fiberglass batts , however, are less expensive, costing on average $0. Cellulose insulation is calculated based on the depth of the blown-in insulation. Blown-in insulation requires the least amount of work, but requires special tools and equipment. Newspapers and wood fibers are the major materials used to create cellulose insulation.

However, because cellulose contains natural wood products, it is treated with borax-based additives to make the insulation fire retardant and to repel insects. High R , radiant and vapor barrier.

The R-value is determined by the depth of material installed by the contractor. The more depth, the higher the R-value. R-value requirements are governed by the Authority Having Jurisdiction (AHJ) in each state or municipality. Available in batts and as loose-fill, cotton insulation has many of the same qualities as cellulose insulation. Like cellulose , cotton shouldn’t be installed in places with moisture issues, and it contains a high percentage of post-consumer recycled content.

High-Performance Foam Insulation Though dense-pack cel­lu­lose and fiberglass batts offer decent R-values, they pale in comparison to liquid foam. Kraft paper-faced glass batt insulation is widely used in walls. It would appear that for every insulation fire that starts in the area where cellulose is commonly use insulation fires start in areas where paperfaced glass batts are usually found. Cellulose naturally absorbs and retains moisture, which can lead to mold growth, which is, of course, a health hazard.

Fiber glass and mineral wool is safe to manufacture, use and install when safe work practices are followed. It is an ideal option for retrofits where it would be impractical to remove walls or siding to put in batts. Loose cellulose or fiberglass and fiberglass batts can only lay between ceiling joists on the “floor” of the attic.

Laboratory tested R-Values for spray foam insulation are comparable to (open cell) or better than (closed cell) the R-Values for cellulose and fiberglass insulation. Both cellulose and fiberglass insulation provide about the same level of insulating power or r-value per inch with slightly different based on the installation procedure.
