Insulation In This Dunes West Custom Home June 23, 2010 Status Date ![]() The installation of an open-cell spray polyurethane foam system has started. Closed-cell polyurethane spray foam is
among the most efficient insulating materials commercially available,
with R-values commonly around 6.0 per inch. Closed-cell foam
incorporates an insulating gas that is retained within the cells (foam
"blowing agent"), which leads to the highly efficient insulating
properties of the material. In the U.S., insulation is measured in
"R-Value" (R= resistance to heat flow), and closed-cell polyurethane
spray foam has among the highest R-Values of any commercially available
insulation. In addition, the closed-cell nature of this foam provides
for a highly effective air barrier, low moisture vapor permeability
(often referred to as the "Perm" rating), and excellent resistance to
water. The most common foam density for closed-cell polyurethane foam is
approximately 2.0 pounds per cubic feet. Years of research and
commercial experience has shown that the 1.75 – 2.25 lb/ft3 density
range provides the optimum insulating and strength characteristics for
most building applications. Closed-cell polyurethane foams are usually
characterized by their rigidity and strength, in addition to the high
R-Value. Also, studies show that wall racking strength can by doubled or
tripled when closed cell foam is applied.

But there are different drywall types and it pays to install the right drywall in the right location. Special drywall that is water resistant is made for wet locations. Regular drywall can fall apart if allowed to get wet or damp on a regular basis.
