How to Handle Fiberglass Batt Insulation

Fiberglass batt insulation is commonly used to insulate interior walls. Proper insulation can dramatically lower your utility bills, and is straightforward to work with and install. Fiberglass batts do pose a serious health hazard if not properly handled, as the minute fiberglass fibers can irritate eyes, skin and lungs. As with all home projects, safety is of paramount importance when installing this type of insulation.
