The installation of insulation varies depending on the type of material used:

• Rolls and Batts: This includes fiberglass, rock wool, and other materials made of fibers such as denim. They usually come in standard wall stud spacing widths.
• Loose-fill Insulation: Fiber materials, such as cellulose, which come in small particles, need to be blown into wall spaces.
• Rigid Foam Insulation: This type of insulation is usually cut to fit into wall spaces.

Some types of insulation should be installed by professionals, such as spray-in foam insulation in large awkward areas like the attic. Others can be done by you with help from our do-it-yourself section.  Whether you do it yourself or hire someone to install for you, it is important to know the behavior of the material you are working with to ensure proper installation.
