Insulation is a vital component of climate control in a home. Heat will naturally distribute evenly through the air, so if you have a warm room and cold air outside, that warm air will naturally diffuse out into the colder air. While insulation does not completely prevent this from happening, it provides a barrier that effectively slows the process down so your home stays warmer or cooler for a longer period of time. While duct tape is not an effective insulator by itself, it can be used to greatly improve the performance of your insulation.
