Preston Insulation uses two different types of blown-in insulation: fiberglass and cellulose. The fiberglass based blown-in insulation is made from molten glass that is spun into fibers. Most manufacturers use 20%30% recycled glass content.
Cellulose blown-in insulation is composed of up to 85% recycled newsprint. The remaining content is most commonly a mixture of ammonium sulfate and borate that functions as a fire retardant. These chemicals also deter insects, rodents, and mold.
Blown-in insulation must be applied using an insulation blowing machine and is designed for both open-blow applications (such as attic spaces) and closed-cavity applications (such as walls or vaulted ceilings). Blown-in insulation creates a tight fit in each stud cavity and seals around all outlets, pipes, wires, etc. The tight seal created makes blown-in insulation a great sound barrier as well as insulator. Our installers are trained to eliminate settling by creating the perfect combination between the netting and the amount of compression in each cavity.
There are three variations to the blown-in fiberglass and cellulose
options above. They are fiberglass Blown-In-Blanket (BIB), Dry
Pack Cellulose and Spray Applied Cellulose. The first two are
similar in that the wall/ceiling is covered with a 'netting' that
serves to tightly contain the material in each cavity and eliminate
settling. Spray Applied Cellulose is different because the cellulose
is mixed with a latex adhesive, misted with water to activate the
glue, and blown into wall cavities.
Blown-in insulation is very popular in open wall spaces and will
dramatically reduce your heating and cooling costs. Not only will it
reduce your monthly utility bills but you can take advantage of the
rebates and tax credits from the utility companies and the federal
government. Learn more about available energy efficiency rebates
