Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.

Insulation can be easy to install, depending on the condition of your walls, but there are many safety considerations and potential challenges involved. For example, most types of insulation are made from materials that can cause irritation if inhaled or if they come into contact with your skin. Additionally, installing insulation incorrectly can actually make moisture issues in your home worse.

If you plan on heating your garage, you must install a vapor barrier when drywalling the garage. A vapor barrier protects your garage from frost and mold that can occur through condensation. If your garage is unheated, you don't need to install a vapor barrier. The only exception is if you regularly crank the heat in your car before getting in it. In this case, you may still want to install a vapor barrier, as your car can heat your garage.

The life span of fiberglass insulation can be as long as 80 to 100 years, but because of changing building codes, it’s best to get your insulation checked every 10 to 15 years. Signs of degrading fiberglass insulation include bits of batts on the floor or batts detached from frames. Having optimal, healthy insulation in your home will improve its energy efficiency, lowering your monthly bills.
