Doorbell Installation questions, answered by experts

Periodic checks for moisture or pest issues ensure consistent performance.

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.

In addition to adding insulation to your attic, you may want to add a radiant barrier. A radiant barrier works by using reflective material, such as foil, on the attic floor. As heat penetrates the roof and enters the attic, the radiant barrier reflects the heat upward and back through the roof. If you receive a lot of direct sunlight on the roof, using both a radiant barrier and insulation in your attic can provide significant benefits.

Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2.

The primary reason that insulation saves you money over time is that it reduces your energy bills by making your home more energy efficient. A crucial part of an insulation system is a properly installed vapor barrier. Local building codes dictate whether your insulation requires a vapor barrier based on the type installed. While some high-quality wool insulation may not technically need a vapor barrier, most municipalities still require one to meet code.
