"We have worked extensively for a couple of modular (not manufactured! - these are trailers = double wide) builders, one completing Energy Star Certs.  In my experience in the mid-Atlantic, they all now do a pretty good job of gasketing the mate…"

"I observed a similar situation made worse by having the thermostat mounted on this "interior" partition wall. The cold wall fooled the thermostat into thinking the room was actually colder than it was.  On top of that, the heating…"

"Modular homes (double wide where they are delivered in 2 pieces them attached on site) typically in the center where they attach the 2 pieces together there is have an open airway from the belly to the attic. Through stack effect cold air from…"

"Yup,  I'm not sure you want to even try tightening up a modular home built before 1975.  I think it's pretty risky.  These were not homes designed to last fifty+ years.  I've seen the fiberglass in those old walls…"

Dennis Heidner replied to John Lile's discussion Air Sealing Manufactured Home
"You made some very important observations. It's really important to think about how tight you air seal a modular home.  Replacement air for combustion devices such as stoves, furnaces and hot water heaters depend on those leaks. Tighten up…"

"Unless the home is on a permanent block or concrete foundation, attempting this is a lost cause.  Air sealing and insulating skirting is futile. Depending on the local climate, soil conditions, you then have the same challenges associated with…"

"Actually, it was only in 1976 that any standards at all were applied to mobile homes:  U.S. Department of Housing and Urban Development (HUD). The Federal Manufactured Home Construction and Safety Standards (commonly known as the HUD Code) went…"

"You didn't mention anything about the age of these homes.  Early mobile/modular homes (1960's) sometimes had walls that were made with 2" thick walls,  HVAC duct coupling between sides of a double wide - depended on the…"

"Notwithstanding the typical low budget for these homes, it seems like encapsulating the crawl might actually cost less in some cases."

"Thanks Ed, Yes the duct system is outdoors. It came from the factory that way. After working on Mobile homes for 25 yrs in the WAP program I've found very often the bulk of the air leakage reduction often comes from the duct…"

Ed Minch replied to John Lile's discussion Air Sealing Manufactured Home
"Chris I agree, and then notice that puts the duct system outside of the house.  So the duct systems frequently have to be rebuilt, sealed and then insulated.  And if the return system is a series of holes along the edges using the…"

"Hi John, The primary air barrier of all mobile home is the subfloor and that is what should be air sealed, just like in a site but home. The road barrier material is designed to hold up the insulation and protect everything above it when being…"
