What the others have said, is true. Trailers have not enough
wall thickness, and seldom enough insulation in the roof.
And leaky windows. And they lose heat under the floor.
What I've done in mine. A couple friends and I cut open the
ends of the roof, and blew in several bags of cellulose. I
had some 2 inch PVC left over from another job. That fit
into the blower hose, and allowed the guys to inject fluff
farther in. I'm sure the center didn't get insulated, but
it's better than it was.
A couple of the windows were single pane. I packed in pink
fiberglass, and then stapled plastic on the inside. Helps, a
lot. Looks awful. Who cares?
Under the trailer, I found some of the heat run,
uninsulated. That got packed with fiberglass, and then mylar
foil bubble wrap stapled up from under.
When it starts to snow, I fill the floor model humidifier,
and keep a little humidity in the trailer. During the bitter
cold, it takes about two galons a day of water. Which tells
me I'm losing a lot of air some how. I should go around and
do what I can to tighten up some more.
Also installed a 90 percent efficiency furnace, which helps
a bit with the fuel costs.
