To understand the condition of mobile home insulation and thus to decide what steps are worth taking to reduce home heating or cooling costs for mobile homes, doublewides, and trailers, we need to inspect the structure focusing on leaks, water damage, and especially air leaks around windows and doors.

If we don't fix those problems first, efforts to add insulation in the ceiling, walls, or floor may be wasted.

Energy improvement choices for manufactured homes (mobile homes, doublewides, trailers)

Mobile home with bad roof (C) Daniel Friedman

The first citation below offers these suggestions for improving the energy efficiency of mobile homes. For older mobile homes (built before 1976) the following list sets priorities for reducing heating & cooling costs for these older structures.

We have added comments, interpretation and suggestions to bring a dose of (in our opinion) reality to the government's advice and I've re-ordered the suggestions into a priority based on most return for least cost and effort. According to US HUD (

Experiments conducted on pre-1976 manufactured homes by the National Renewable Energy Laboratory (NREL) from 1988 to 1991 found that these retrofit measures resulted in a 31% reduction in heating fuel usage. [1]
