Installing a Vapor Barrier on Our Mobile Home

  • Dig a trench around the perimeter of the mobile home, making sure it is at least 6 inches deep
  • Line the trench with gravel and compact it with a tamper
  • Install a layer of vapor barrier material over the gravel, using landscape staples to secure it in place
  • Cover the vapor barrier with another layer of gravel and compact it again with a tamper
  • Fill in the trench with soil, tamping it down as you go, and replant any grass or other vegetation that was disturbed during the installation process

Do I Need Vapor Barrier under My Mobile Home

Vapor barrier is one of those things that mobile home owners often wonder about. It’s not required by code in most areas, but many people choose to install it anyway. So, what is a vapor barrier and do you need one under your mobile home?

A vapor barrier is a material that helps prevent moisture from passing through it. This can be important in both hot and cold climates. In the summer, a vapor barrier can help keep your home cooler by preventing outside air from coming in.

In the winter, it can help prevent condensation on your walls and floors. There are two main types of vapor barriers: polyethylene sheeting and kraft-faced fiberglass insulation. Polyethylene sheeting is the cheaper option and is available at most hardware stores.

Kraft-faced fiberglass insulation is more expensive but will last longer. So, should you install a vapor barrier under your mobile home? It depends on several factors, including your climate and whether your home is new or used.

If you live in an area with high humidity, or if you’re concerned about energy efficiency, then installing a vapor barrier may be a good idea. However, if you have an older mobile home that isn’t well-sealed, then a vapor barrier could actually make things worse by trapping moisture inside your home. Ultimately, it’s up to you to decide whether or not to install a vapor barrier under your mobile home.

Installing a vapor barrier beneath your mobile home is an important part of protecting your home from moisture damage. There are a few different ways to install a vapor barrier, but the most common method is to lay down a layer of heavy-duty plastic sheeting.
