Spray Foam

What about the walls that are not poured concrete?  There were some wooden walls put up... how is the same superior level of insulation ensured (R-Value attained)?Simple, we use sprayfoam.  Choosing a soya based spray foam for environmental and indoor air quality reasons, the walls end up tightly sealed eliminating air infiltration that is typical in stick-framed walls and homes.  That spray foam insulative layer on the inside combined with the styrofoam layer underneath the stucco on the outside of the home ensures warm winter days and cool summer days.
