Insulating Walls

Adding fiberglass batts or blown-in cellulose to stud cavities can greatly improve a residence’s comfort and energy efficiency. Understanding the proper ways to access the building cavities and repair the home when finished are just as important as the actual installation of the materials.

In this lesson, you will learn to install fiberglass batts in walls, blow cellulose insulation into wall cavities from the outside of the home and how to blow cellulose insulation into wall cavities from the inside of the home.
