Does insulation have to face up or down?
The paper needs to be facing towards the living area when you install it. So, for instance, if you’re installing insulation in your crawlspace, the paper needs to be facing upward toward your floors. Or, if you’re installing it in an attic, it needs to be facing downwards toward your ceiling. When To Use Unfaced Insulation
Should I insulate my attic or basement ceiling first?
Get professional evaluations to confirm that your home will benefit from attic insulation. As long as there’s no insulation there, you’re almost guaranteed to save more money focusing on it first instead of the basement ceiling. Weatherstripping helps cut down drafts and prevent energy loss via doors and windows.

Why is paper vapor barrier used in insulation?
That’s because the paper contains a layer of asphalt adhesive which prevents water vapor from passing through it. If the insulation is installed with the paper vapor barrier facing away from the heated part of the home, moisture from humid inside air can condense and become trapped in the insulation during cold winter months.

Faced vs Unfaced Insulation
There are mainly two types of insulation: faced and unfaced. But what is the difference between them?
Where To Use Faced And Unfaced Insulation
Unfaced insulation can be used anywhere to insulate two areas thermally and noisily. Faced insulation is used when two spaces need to be insulated from moisture in addition to heat and noise.
Conclusion
Faced and unfaced insulation play different roles in the insulation of a house and must be applied correctly to limit heat loss, sound, and vapor transfer. Faced insulation used with the vapor barrier facing the wrong way can lead to moisture trapped, leading to mold growth and rot of the home’s wooden structure.

Between Rafter Insulation. When installing between the roof rafters of finished attic spaces, you can use either faced or unfaced batting. When using insulation that has paper or plastic batting, that moisture barrier should face outward toward the attic space.
Why add insulation to attic floor?
The extra batting increases the R-values so it further slows warm air migration. The additional layer must be unfaced, otherwise, moisture can get trapped between the layers of insulation and cause mold or mildew.
Do you need to face batting in the attic?
If you install batting between your attic floor joists, the material should be faced. Since the attic floor is the ceiling of the living space below, the facing installs against the top of the ceiling drywall or plaster. The facing then provides a layer of moisture protection between the living space below and the insulation materials above.
Does moisture cause mold?
As a result of evaporation, air carries some moisture with it. If this moisture gets trapped in the folds of insulation, it can lead to mold and mildew. Furthermore, excessive moisture can damage the framing lumber of a home’s structure over a long period of time.

What type of insulation should I use for a house?
Unfaced insulation is another type of insulation you can use when there’s no need to have moisture control in an area. Although people commonly think that unfaced insulation is the lesser choice, it’s simply not needed in every space of the house, and can be a cheaper alternative that’s still effective.
What is the best insulation rating for a hot room?
People living in warm areas won’t need as much, with a rating of between R-30 to R-60 being better to deal with the hot temperatures. Because the insulation is more important for regulating hot temperatures than for cold, it’s best to stick to the recommendations for these climates. Unfaced batt insulation can help to improve the R rating ...
How to ensure minimal heating and cooling?
One of the simplest ways to ensure your home requires minimal cooling and heating energy usage is with insulation . Insulation is a major part of any new home or renovation and when done right, it can have a significant and positive impact on how much energy your home HVAC bills are.
Why is insulation important?
The goal of insulation is to provide a protective barrier that maintains a consistent temperature indoors. However, it is possible to apply too much insulation so that it affects air quality. With over-insulation, you make it easier for moisture to get trapped inside which can lead to mold and deterioration.
Can you use unfaced insulation on both sides?
Unfaced insulation can be batt or paper as well, but with both sides being the same. There’s no need to have a certain side with moisture protection and it’s used where you might need insulation on either side of it, like beneath two levels of a house or in an attic where people use the space above and below.
What is the worst thing to do when applying faced insulation?
The worst thing that you could do when applying faced insulation is to leave the paper side exposed. That leaves the Kraft paper open and vulnerable to conduction. To reduce the risk of fire, cover the faced insulation with a layer of drywall sheetrock. Also, you want to be sure that the facing is directed towards the inside of your home, i.e., where it is air-conditioned.
What is the difference between faced and unfaced insulation?
The main difference between faced and unfaced insulation is that faced insulation keeps moisture out because it is lined by Kraft paper or plastic, whereas unfaced only provides insulation. Faced insulation is ideal for ceiling, floor, attic, finished basement, and exterior falls installations. Unfaced insulation is useful for noise reduction, ...
What is faced insulation made of?
More often than not, faced insulation is made out of fiberglass. Unlike unfaced insulation, faced insulation has a vapor retarder that keeps moisture out. The vapor retarder’s primary function is to keep moisture from spreading within the walls and throughout the house.
What to wear when applying foam insulation?
Wear eye and face protection. It is extremely important to wear face and eye protection while applying foam insulation. Breathing in the chemicals in foam insulation can cause asthma and long-term lung damage, scarring, and breathing troubles. Proper face protection is also critical when applying blown-in insulation.
Can you use unfaced insulation?
You should only use faced insulation as the first layer of insulation. The Kraft paper itself is highly flammable. To make things safe, cover your unfaced insulation with drywall to prevent the risk of a fire.

Creating a Moisture Barrier. As a result of evaporation, people breathing and plant respiration, air car ries some moisture with it. Should those water droplets get caught in the folds of insulation, it could lead to mold or mildew. Excessive moisture over long periods of time can rot the framing lumber that makes up the home’s structure.
Can you use batting in the attic?
You can use either faced or unfaced batting for this installation. When using insulation that has either paper or plastic facing, that moisture barrier faces outward, toward the attic space. Even if the attic space is unheated, it typically is warmer than the outside air in winter.
Do you need to face batting in attic?
The batting material must be faced, and at least as thick as the joists are wide so the batting is nearly flush with the top of the joists. Since the attic floor actually is the ceiling of the living space below, the facing installs against the top of the ceiling drywall or plaster.
Do baffles seal up rafters?
Install baffles against the roof sheathing between rafters so insulation does not seal up these avenues of air circulation. Some attic floors that already have a layer of insulation could benefit from an additional application over the existing layer.
Can moisture damage insulation?
Excessive moisture over long periods of time can rot the framing lumber that makes up the home’s structure. Trapped moisture also can damage the loft of the insulation. Loft is the thickness of batting insulation, and it helps define the R-value of the material.
Can you use plastic over unfaced batting?
When choosing unfaced batting insulation for rafters, you must staple sheets of plastic over the batting to accomplish the necessary moisture barrier. Air movement is critical in the attic so moisture moves outside the home.
