Does insulating windows with plastic work?

Should you remove old insulation before adding new insulation?

• <div><p>You do not always need to remove old insulation before adding new.

Q: Do you need a vapor barrier when drywalling a garage?

• <div><p>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.</p></div>

Q: What happens if you don't install a vapor barrier?

• <div><p>While not every wall requires a vapor barrier, if you do need one and don&rsquo;t install it, moisture can get between the walls of your home. This can lead to water damage from mold growth or rot, and the excess moisture could also attract pests, including termites, cockroaches, or ants.</p></div>

Q: Do I need to air seal my attic before installing insulation?

• <div><p>Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line. </p></div>
