Be careful to compare apples to apples in pricing. Price conventional homes with a wall R-value of 35 and see what your builder says. Code is R-19 to R- 21 and the new International Building Code is R-26. Why is the minimum wall insulation level going higher you may ask?

Bruce, thank you very much, you clarified my design concerns, about my passive & active solar designed home. You have reaffirmed my confidence to build a solar home here in Washington.

Did you know that the vapor barrier installed by code attributes to mold growth?

The United Building Code (UBC) has the same design for all climates & weather patterns? Is this logical?

The true insulation  factor for a 2x6 fiberglass batten wall system with is R- 12.7 not R-19.
