Fiberglass Blown Insulation

Fiberglass Blown Insulation Knoxville & Maryville TN

Fiberglass blown insulation or blow-in insulation is ideal for attics or odd-shaped spaces where fiberglass batt insulation may not fit. It’s also a great option for improving the energy efficiency of your home. Another blown insulation option is cellulose insulation.

Benefits of Fiberglass Blown Insulation

Easy to Install

A professional can take care of blown-in insulation much more quickly than they can install other types of insulation. Usually, two installers can do a house in a few hours.


Adding loose-fill insulation to your attic is one of the fastest paybacks of any home improvement project. The amount of money you save on energy costs will add up quickly over the next couple of years, more than paying for itself, and even bringing a return on your investment.

Energy Efficient

Because loose-fill insulation is a monolithic layer of insulation without seams like are found in batts, studies have shown that loose-fill insulation performs up to 22% better than batts of the same R value.
