Faced vs unfaced insulation

Faced vs unfaced insulation. Insulation is required in homes to control the movement of warmth through the walls and ceiling. The residence can stay warm in the winter and cool in the summer by reducing heat transmission through the walls, regardless of the outside temperature.

This covering also acts as a sound barrier, preventing you from hearing anything occurring on the outside.

Insulation can also assist in preventing moisture from entering the home, which is beneficial for homes in coastal areas and rainy places.

However, there are substantial distinctions between faced and unfaced insulation, so knowing which sort of insulation you’re placing or updating is critical to ensuring you get the optimum insulation for your home.

Faced or the type with paper is typically used in new construction, such as in walls, ceilings, floors, and in crawlspaces. Unfaced insulation – the type that does not have a paper layer – could be added to an attic or to place between existing floor joists if you need additional insulation inside of your existing room framing.

Paper Vapour Retarder for Faced Insulation

The clad insulation contains a moisture barrier for paper. Both panel insulation and bare insulation are good choices for home insulation, but their differences help determine the best location in the house for each type of installation.

The main difference between coated and uncoated insulation is that coated insulation usually has a paper moisture barrier or retarder attached to one side of the insulation. 

The purpose of the moisture barrier of paper is to prevent moisture from entering the walls and ceiling of the house. This is especially useful in humid places such as coastal cities.

Also, note that some insulation uses vinyl or lightweight aluminum foil as a moisture barrier instead of paper. However, these alternative materials may not be approved for use in some regions.

Therefore, be sure to read local ordinances and building codes before deciding on home insulation. 

Unfaced Insulation Is Non-Combustible

 One of the benefits of using uncoated insulation is that it is usually considered a non-flammable material. Uncovered insulation is not flammable. You can reduce the risk of fire by providing a barrier between the inner and outer walls that slows or stops the spread of the flame. 

Pre-bricked insulation cannot make the same non-flammable claim due to the moisture-proof layer of flammable paper firmly attached to the insulation.

However, it is common to use a layer of insulation covering the exterior walls and attic ceilings to prevent water from entering the house. On the other hand, you can add uncovered insulation to increase heat retention and reduce fire risk.

Make sure the moisture barrier of the paper is on the outside of the insulation stack, not in the center. If it is between two insulation layers, moisture can build up in the insulation and lead to mold and mold.

Insulation with a face is simpler to apply

DIYers searching for a more straightforward approach to insulate their home should pick faced insulation over unfaced insulation because faced insulation is often much easier to install.

This is why the paper vapor barrier holds the insulation intact, enabling it to be rolled, transported, and stapled before breaking apart.

Because unfaced insulation lacks the same cohesive strength as facing insulation, it is more prone to tearing during placement. Furthermore, because nails do not adhere well to unfaced insulation, the installer must rely on the insulation to stick to the wall or ceiling.

Over unfaced insulation, some installers will apply a plastic vapor barrier to keep moisture out while also securing the soundproofing to the target surface.

Price Gap Between faced VS Unfaced Insulationprice gap between faced vs unfaced insulation

The price gap between faced and unfaced insulation is small. Faced insulation ranges in price from $0.50 to $2 per square foot of wall or ceiling. Unfaced insulation goes in price between $0.50 and $1.75 per square foot. 

Because of the slight price difference, faced insulation costs $0.10 to $0.25 more per square foot than unfaced insulation, most likely due to the vapor barrier.

Minor modifications should not be affected by this slight price rise. Still, if you need to insulate your entire home or perhaps numerous properties, the price difference may influence your decision.


Upgrading your insulation is one of your best investments, but make sure you’re using the right sort. Insulation in rolls, known as batts, is accessible in 2 variants: faced and unfaced. Faced or paper-backed is commonly utilized in first-time applications such walls, ceilings, floors, and crawl spaces.

If you’re adding insulation to your attic or between feet while living space is above and below, you’ll want to utilize unfaced insulation (the kind without paper). Unfaced is also the ideal material to use for soundproofing interior walls.
