Blown-in Insulation

Blown-in insulation provides a dense, effective barrier against heat loss that is also among the greenest insulation options. It offers a low impact on the environment while providing immediate energy savings when installed in attics, walls and hard-to-reach spaces.


Proper installation is a must for blown-in, or loose-fill, insulation. Special equipment and safety measures are required to ensure long-term performance.

In addition to being a mostly recycled product, cellulose blown-in insulation includes fire retardant properties. It also resists insects, rodents and mold and forms a good sound barrier. For more information about Sound Insulation, click here.
