Urethane foams can make a major contribution to improving the energy efficiency of buildings when they are used as an air leakage control material or as a component of an air barrier system. [continue reading]
Most newer manufactured homes in the Pacific Northwest, as well as many older mobile homes, have a vapor retarder on the inside of the wall cavity--typically right behind the gypsum board. However, many older mobile homes, especially those built before the 1980s, were manufactured with a vapor retarder on the outside of the wall cavity--generally right behind the metal (or sometimes wood) siding.

Just because a wall has R-19 insulation in it does not mean it's an R-19 wall. Using the R-value of the insulation between the studs (the "cavity R-value") as an overall wall R-value is similar to using the center-of-glass value for a window--it ignores the effect of framing. [continue reading]
