Those who own older trailers know that keeping heating costs down can be a problem in colder climates. Even people who have newer homes can run into problems, depending on how well their trailer home was set up. While many mobile homes today come with a great deal of insulation, you can add insulation to a trailer home to keep costs down further. There are various ways to add insulation to a trailer home; each is cost-effective, meaning the energy savings will pay for the cost of the project.
Things You'll Need
- Foam spray
- Insulation blower
- Fiberglass insulation
- Circular saw
- Double-sided tape
- Galvanized metal patch
- Caulk roof coating
- Measuring tape

Measure the total area around each window and door, using the measuring tape. This will be the total amount of weatherstripping you will need for that door or window.
Measure out and cut the needed size for each door or window from the roll of weatherstripping. Cut the needed strips for one window or door at a time. Measure each side of the door or window where the weatherstripping will be applied; this is usually the sides and top, but can include the bottom if a gap is present.
Open the door or window. Set the strip into place with the tacks at each end. Staple the strips to the frame around the door or window, not to the door or window itself. Do this for each strip you are using.
Locate any sizable space where the outer wall of the trailer home meets the roof. Pry open a space between the outer wall and the roof with a short crowbar. If you need to cut a hole, use the circular saw. Make sure the hole is large enough for the blower nozzle of the fiberglass insulation blower.
Set the blower nozzle into the hole. Use the PVC pipe as an attachment to the nozzle to extend the reach of the blower.
Fill the roof cavity with the insulation. Spread the insulation evenly throughout the roof, using a slow, sweeping motion from side to side.
Cap the hole. Apply two-sided tape around the edges of the hole. Set the metal patch over the hole. Caulk the seams. Cover the patch with the seal coating.
Apply insulation underneath the floor of the trailer home. This can be done either by blowing insulation into the underside cavity, or using rolls of R-19 insulation similar to what is used in attics.
Nail a layer of plastic sheeting across the entire underside of the trailer home. This will help keep out unwanted creatures, keep the insulation dry, and provide further warmth from any drafts that do get underneath. Use the wood nails and space them every 4 inches.
Set up or repair skirting around the perimeter of the trailer home. This will eliminate most drafts underneath the trailer home that account for most cold floors. Use foam insulation boards for emergency skirting if you cannot afford skirting. Set the foam underneath the edge of the trailer siding and slide it into place. Set wood stakes into the ground to hold the foam or skirting in place should a strong wind come.
Replace the windows. Use windows with a U-value of 0.35 or below to insulate the window in colder climates.
Caulk the seams between the window frame and the trailer home. As trailers settle, gaps can form between the frames and the walls. Caulk the edges of any vents as well as where any pipes enter the house.
Level the home before winter. Homes not level have windows that will not close tightly, or leave gaps between them and the window frame. Doorways can also become jammed. Leveling the trailer home will ensure insulated windows and doors seal properly against the weatherstripping and frame.
