What is the difference between faced and Kraft-faced insulation?

What is the difference between faced and Kraft-faced insulation?

The Difference Between Faced And Unfaced Insulation Faced just means that kraft paper is attached to the insulation itself. The paper helps improve the sturdiness of the insulation so it doesn’t fall down as much. Unfaced insulation is just as good as faced, but it doesn’t have that paper attached to it.

What is the purpose of kraft paper on insulation?

The facing on kraft-faced insulation is made of kraft paper with an asphalt coating that makes the paper impermeable to water vapor. The paper creates a vapor barrier that helps keep the water vapor in the warm, moist, heated indoor air from migrating outward into the wall or other structure.

Should insulation be installed paper face in or out?

Regardless of whether fiberglass insulation is installed in a wall, attic, or crawlspace; the paper facing should always face toward the inside of the home. That’s because the paper contains a layer of asphalt adhesive which prevents water vapor from passing through it.

What’s the difference between unfaced and Kraft faced insulation?

Unfaced means the insulation lacks a vapor retarder (paper or plastic facing). Kraft-faced insulation includes a paper vapor retarder, which helps prevent mold and mildew.

Which is better, faced or unfaced wall insulation?

Unfaced insulation of inner walls will lead to more energy efficiency if there are rooms in the house that inhabitants do not always occupy. Another significant advantage of using unfaced insulation for interior walls is the soundproofing effect of insulation that will enhance privacy.

When to use each type of insulation in a home?

When To Use Each Type Of Insulation When local building codes require a vapor retardant, faced insulation is one of the best options. The Kraft paper on one side of faced insulation keeps moisture from spreading throughout the walls or ceiling. You should only use faced insulation as the first layer of insulation.

What’s the difference between Batt and roll insulation?

There are four main types of insulation: Roll and batt insulation are lumped together as Blanket insulation. The critical difference between the two is that roll insulation can be rolled out and cut, whereas batt comes in precut pieces that are installed separately.
