Yes. In your crawl area, you need a vapor barrier. Furthermore, in your crawl space, a moisture barrier provides the bare minimum of protection. You can avoid costly repairs by using a vapor barrier.

The preferred insulation for crawl space inside walls is two-inch expanded polystyrene foam board.

R30 is one of the standard R-values for insulation, which is a measurement of a material's resistance to heat conduction. If heat conduction is reduced by 97 percent, insulation is rated R30.

It is possible to over-insulate your home to the point where it is unable to breathe. The goal of home insulation is to keep your home's interior as airtight as possible. Moisture can get trapped inside those layers if it becomes too securely sealed with too many layers of insulation. Mold will begin to grow at this point.

The short answer is that if you want to make your home more energy efficient, you should insulate the crawl space. A properly insulated crawl space is recommended by the Department of Energy.

R-15/19, for example, is how the code provides insulation needs based on location. On the interior or outside of the perimeter wall, R-15 continuous insulation (board insulation) is required, or R-19 cavity insulation on the inside wall.

In most cases, a higher R rating for insulation equals better climate control and energy efficiency for your home. A greater R-value insulation usually comes with a larger price tag. Check the manufacturer's listed R-value per inch of thickness for each kind and substance of insulation.

R-13 to R-23 is a frequent suggestion for exterior walls, whereas R-30, R-38, and R-49 is popular for ceilings and attic areas.

In warm climates, R-843-460-8391") insulation under floors is recommended, while in cold climates, R-25 (6" to 8") is recommended. Make sure the insulation fits tightly between the joists and that the paper vapor barrier is pointing up toward the heated living room.

Rigid foam insulation board is the best type of insulation for crawl spaces. Instead of placing foam insulation between floor joists in the crawl area, the foam board is installed against the foundation walls of the crawl space.

Insulate the floors above chilly regions, such as vented crawl spaces and unheated garages, but don't forget about the subfloor. This will help to guarantee that your home is as energy efficient as possible. Slab flooring constructed directly on the ground are good for insulation.

If there is moisture in your crawl area, the fiberglass insulation will absorb it and retain it against your sub-flooring and floor joists like a sponge. Mold can grow not just on the wood, but also within and on the insulation.

It's critical to seal insulation and cover it with a vapor barrier to avoid moisture and mold, which are often following behind. If your crawl space isn't ventilated, insulate the crawl space's walls rather than the room's subfloor.

The overall cost of insulating a 2,000 square foot home in the United States is from $2,700 to $3,300, including labor, supplies, and installation. The average cost of a Do-It-Yourself project is $700-$1300 for the entire project.
