Loose Blown Attic Insulation - We use 3 primary types of loose blown attic insulation; Fiberglass, Cellulose, and Cotton(actually recycled blue jeans). We make every effort to insure using only formaldehyde-free products such as Johns-Manville Fiberglass, also cellulose is a recycled material and has excellent sound absorbing properties as well having a fire retardant added. Fiberglass is the cleanest product for our workers to install, but we promote customer choice. Fiberglass has an R-value of approximately R-3/inch, Cellulose is approximately R-3.6/inch, and Cotton at approximately R-3.7/inch. In attic applications where a desired(and often required) R-factor needs to be met, it can be achieved by simply altering the amount to be installed. While these loose blown insulation materials are not typically air barriers, they are always a less expensive means of reaching an R-value goal. We even combine these materials with a sealcoat of Spray Polyurethane Foam to achieve air barrier and R-value in a more economical manner. It should be noted however that any of these materials require a minimum thickness of about one foot, this doesn't work where keeping an attic floor open for storage use is desired, so alternatives need to be considered to have storage area.
