What's the Difference Between Faced vs Unfaced Insulation?

If you're looking to improve the insulation in your home you may have come across two options faced and unfaced insulation. But what's the difference between these two types of insulation? And which one is right for your project? Keep reading to learn more about these two types of insulation and why they are important.

Faced Insulation

Faced insulation is a type of fiberglass insulation that has an attached vapor retarder a type of material designed to slow down the process of moisture vapor moving through its fibers. This is especially important for areas that are prone to condensation or moisture accumulation, such as attics or walls near bathrooms or kitchens. The vapor retarder helps keep moisture from becoming trapped in the walls and ceiling, ensuring that your home stays dry and comfortable.

Faced insulation is the insulation that has a facing material attached to one side. The facing material is typically made from kraft paper, foil, or plastic and acts as a moisture barrier. The facing material can also help to improve the insulation's fire resistance and reduce noise transmission.

There are two types of facing materials used in faced insulation: kraft paper and foil. Kraft paper is the most common type of facing material and is typically used in fiberglass batt insulation. Foil, on the other hand, is often used in rigid foam board insulation.

One of the main benefits of using faced insulation is that it helps to control moisture, which can help prevent mold growth and improve indoor air quality. Faced insulation is also easier to install since the facing material provides a barrier to prevent air leakage.

Unfaced Insulation

Unfaced insulation, on the other hand, does not have a vapor retarder attached to it. This type of insulation is best used in areas where moisture isn't an issue, such as in basements or crawlspaces. It's less expensive than faced insulation because it doesn't have a vapor retarder attached, but it still provides effective thermal protection for your home.

When deciding which type of insulation is right for your project, consider where you're planning on installing it and whether moisture could be an issue there. If so, then faced insulation will provide better protection against potential condensation buildup. If not, then unfaced insulation can be a more cost-effective option that still gives you excellent thermal performance.

Unfaced insulation, on the other hand, does not have any facing material attached to it. This type of insulation is typically used in areas where moisture control is not a concern, such as in walls or ceilings that are not exposed to the exterior of the building.

While unfaced insulation does not provide the same level of moisture control as faced insulation, it is often more affordable and easier to install. It also allows for more flexibility in the installation process since it can be cut to fit around obstacles and in irregular spaces.

Which One Should You Choose?

The type of insulation you choose for your home will depend on personal preference as well as budget constraints. For example, if you need extra soundproofing or don’t want to spend time installing a separate vapor barrier, then face may be the best option for you. However, if cost savings are more important than convenience, then unfaced may be the better choice in this case.
