Dickinson Homes has a Green Wall option that many of their
home owners are choosing to help cut energy bills, especially in
build them. Here is a picture of a sample in the
is constructed.
Alternating 2×4 studs at 16” or 24” on center that provides
a true 8” insulation cavity with an insulation value of R-30. A larger
cavity and higher levels of insulation are nothing new but other wall systems
still have the stud value of R-1 per inch or an R-6 at the stud.

Their Green Wall offers an R-19 at the stud space, increasing
the overall insulation value at the cavity and stud space. They also
double caulk all exterior wall penetrations and tape both sides of the
drywall. In this wall system they also increase the rim joist insulation
to an R-30 as well.
Cost is always a consideration when it comes to energy
efficiency. Icynene and other insulation options add a good deal of cost
over traditional insulation. To upgrade from their standard 2×6 wall to the
Green Wall is less than $1/SF (a fraction the cost of alternatives).
Dickinson Homes build a good number of homes every year with
this wall option and they are becoming more popular. For more information
