Does anyone have experience with insulated skirting? Up here in the north, it gets us out of foundation issues regarding frost, plus it has other benefits for frozen pipe concerns. Does anyone know how much more expensive it is to get installed and also if it is easily removeable for access to the home.

The insulated skirting allows me to ignore frost completely according to their documents. So, I need my HUD 309 inspector to sign off on it and also the local building department (they inspect footing and life safety for parks). Even if my existing slab is not in good condition, I can sawcut the existing slab where my footings are located, dig out an extra 4" of dirt, and fill back to existing slab grade with concrete to provide my 8" footing.

FYI ask if your home manufacturer if they will provide stamped paperwork saying you don’t need any footing other than a 24" W cookie if you are in sand soil conditions. Our local building department allows us to go 24" depth for regular home footings with sand soil but HUD’s are supposedly getting away with a standard cookie.

Last year, we had one brand new home with new slab and insulated skirting. It was the only home in the park that had the sewer line freeze. The outside ambient temperature was 8* and it was 10* under the home. Guess what, the slab was freezing cold. In fact, we had old homes on dirt and regular skirting which were above 32*.
