Which Insulation is Better for Attics: Faced or Unfaced?

When it comes to insulating your attic, you have two main options: faced or unfaced insulation. Faced insulation has a thin vapor barrier attached to one side of the material, while unfaced insulation does not. Both types of insulation are easy to install, but faced insulation is more durable due to its protective layer. Uncoated insulation is ideal for new construction, remodeling, walls, floors, ceilings, basements, attics, and tight spaces.

When installing it between the ceiling beams of already finished attics, you can use coated or uncoated slats. Even if the attic is unheated, it is usually hotter than the outside air in winter. If you have chosen an insulating material without coating for the beams, you should staple plastic sheets over the wadding to create a moisture barrier. Valley Insulation uses a cellulose insulator called Nu-Wool, a high-quality insulator known for its fireproof and anti-pest capacity.

Uncoated insulation simply lacks the coating material that faced insulation has, but this does not mean that unfaced insulation is less effective. You should install attic insulation whenever moisture and humidity are potential risk factors for your home. Some attic floors that already have an insulation layer may benefit from additional application over existing layers. Fiberglass insulation can last 80 to 100 years, but you should still check the insulation after 10 years to make sure you don't need to replace it.

Tom also talks about using cellulose or rigid foam insulation on floorboards to allow storage and additional insulation in an attic. The best way to install spray foam insulation without coating is a nearby insulation company, as it requires skill in knowing what thickness to apply the material and what safety equipment to use. Coated insulation comes in rolls or blocks and has a thin layer of coated material on one side of the insulation. Faced insulation is better for preventing moisture damage; however, it cannot be placed in layers like unfaced insulation.

When deciding between faced or unfaced insulation for your attic, consider the application and whether any type of insulation already exists. Coated insulation is more durable than uncoated insulation thanks to its protective layer, but the durability of the insulation depends largely on the material chosen. Ultimately, both types of insulation are effective at maintaining a comfortable temperature in your home all year round.
