11.3 Mobile Home Windows and Doors
Repairing or replacing mobile home windows and doors is often part of a mobile home weatherization job. Installing storm windows or replacing existing windows is expensive per square foot and isn’t as cost-effective as insulation. However, storm windows and replacement windows are all energy conservation measures for mobile homes that are worth considering.
11.3.1 Mobile Home Storm Windows
Interior storm windows are common in mobile homes. These stationary interior storms serve awning and jalousie windows. Sliding interior storm windows pair with exterior sliding prime windows.
ü Interior storm windows double the R-value of a single-pane window. They also reduce infiltration, especially in the case of leaky jalousie prime windows.
ü Interior storm windows must be operable and egress-rated in egress locations.
ü Consider repairing existing storm windows rather than replacing them unless the existing storm windows can’t be re-glazed or repaired.
ü When sliding primary windows are installed, use a sliding storm window that slides from the same side as the primary window. Sliding storm windows stay in place and aren’t removed seasonally, and are therefore less likely to be lost or broken.

Replacement windows should have lower U-factors than the windows they are replacing. Inspect condition of rough opening members before replacing windows. Replace deteriorated, weak, or waterlogged framing members.
Prepare the replacement window by lining the perimeter of the inner lip with 1/8-inch thick putty tape. Caulk exterior window frame perimeter to wall after installing the window.
Mobile home doors come in two basic types: the mobile home door and the house-type door. Mobile home doors swing outwardly, and house-type doors swing inwardly. House-type doors are available with pre-hung storm doors included.
Existing or replacement mobile home doors should be air-tight, water-tight, and operable. Replace missing or damaged weatherstripping, drip cap, or flashing to ensure that water or air can’t penetrate the opening. Properly adjust the door so that it closes securely, but does not crush or deform the weatherstripping.
