Mobile Home Insulation

Underbelly is the covering provided underneath the mobile home to offer protection to the underside of the home. As the underbelly of mobile homes is open to the elements, it is very important to insulate it properly. Insulating the under belly of your mobile home will drastically improve the living conditions inside the home. It will be easy for the mobile home manufacturers to do this at the time of production in the factory, rather than doing it onsite while installing the home.

Once the mobile home is set up in the location, there will be only limited space under the home and installation of the underbelly can get very difficult. Most of the mobile home manufacturers will provide a fabric barrier or fiberboard to protect the underbelly of the home while the home is being transported. This barrier should be removed before insulating the underbelly and should be reinstalled after the insulation. If you find that the barrier is damaged, you will need to replace it as it is provided to protect the insulation of the home from critters. The steps to install insulation under a mobile home are discussed below.

Instructions

  • Before starting the insulation, you need to lay a moisture barrier underneath the mobile home; 6 mm polythene sheeting can do the job. This barrier is to prevent the ground moisture from getting into the insulation of the home. Besides, the barrier will make it easy for you to crawl under the home.
  • The next step is to take off the road barrier under the home with the help of a flat head screwdriver and a Phillips screwdriver. You may also use pry bars to remove nails.
  • Now you can cover all water pipes with foam insulation and secure the pipes tightly against the belly. The insulation of the underbelly should also cover these pipes to avoid freezing in cold climates.
  • Inspect the seams between the joists and the floor, and the points where wires and pipes pass through the flooring of the home. You can use silicone caulk to seal holes and gaps that you find.
  • Use fiberglass batt insulation to fill the space between joists. You can use paper backed insulation but make sure that the paper side of the insulation faces the ground.
  • Small and difficult to reach areas can be insulated with polyurethane foam. When done, you can reattach the road barrier making use of the same type of fasteners that was used to hold it in place.
