What is blow-in insulation?

The term blow-in, blowing, and loose-fill insulation is used to describe the process of filling stud, joist, and attic floor cavities, with a loose material with a good R-value. While many materials can be used, fiberglass fibers, mineral wool, and cellulose are among the most popular materials for this application. Blow-in insulation is widely considered the optimal means of adding or retrofitting insulation in existing construction wall cavities and attic spaces.

Cellulose Insulation

Constructed of treated cardboard, recycled newspaper, and other wood-based materials, blow-in cellulose is treated with boric acid and additional substances that make it flame and mold-resistant. Packaged in tightly packed bales, installation requires the use of a motorized blower/hopper that churns the cellulose with paddles to mix and loosen it with air, then blows the fluffy product through a hose to fill desired cavities. Benefits include:

Considered a Green Product
Critical Radiant Flux – Greater than or equal to 0.12 w/sq. cm
R-value of 3.7 or greater at manufacturer recommended thickness

Mineral Wool Insulation

Mineral wool blown-in insulation, also known as rockwool blown insulation, is a widely popular insulation used in attic, wall, and ceiling cavities. It is made in a granulated form of rock, steel furnace slag, and additional raw materials. Mineral wool blown-in insulation is a considered top insulation product for its porous matter that traps air. Benefits include:

Fire retardant qualities
Thermal, energy, and acoustical barrier capabilities
Multi construction and climate zone friendly

Fiberglass Insulation

When consumers think of fiberglass, most think of pink rolls or yellow sheets. However, fiberglass insulation is also available as loose fill. Loose fill fiberglass is a mixture of recycled glass and plastic filaments spun into fibers. Blowing in loose fill fiberglass insulation provides a protective layer that reduces the passage of heat and moisture. Benefits include:

Fills gaps in unfinished attic floors
Optimal for attics with irregular joist spacing and obstructions
Increases efficiency of existing insulation as it fills and settles in gaps easily
