When it comes to insulating your attic, you have two main options: faced or unfaced insulation. Faced insulation has a paper vapor barrier attached to one side of the insulation, while unfaced insulation does not. Both types of insulation are suitable for home use, but there are some key differences between them that can help you determine which is best for your needs. Uncoated insulation is the best option if you want to prevent heat from the attic radiating into the living room.
This type of insulation does not have the same cohesion strength as coated insulation, so it is more prone to breakage during installation. It is important to ensure that the paper vapor barrier is on the outside of the insulation pile and not in the center; if it is between two insulating layers, it can cause moisture to accumulate inside the insulation and lead to mold and mildew. On the other hand, coated insulation is a better choice if you want to protect a wall cavity from moisture. This type of insulation has a vapor barrier that can retain moisture and cause mold on the attic floor and on the lower roof. It is also easier to install than uncoated insulation, as staples can be used to secure it in place.
However, coated insulation cannot make the same claim that it is not combustible due to its flammable paper vapor barrier. In addition, some installers add a plastic vapor barrier over uncoated insulation to block moisture and help secure it to the target surface. This can be beneficial if you are looking for a way to facilitate home insulation without using coated insulation. When deciding which type of attic insulation is best for your home, consider both faced and unfaced options. Uncoated insulation may be better for preventing heat from radiating into living spaces, while coated insulation can help protect wall cavities from moisture. If you are looking for an easier installation process, coated insulation may be your best bet.
