Double-stud wall construction consists of two stud-framed walls set up next to each other to form an extra thick wall cavity that can be filled with insulation. They are relatively inexpensive to construct and use readily available materials that construction crews may be more familiar with than other high-R-value options such as structural insulated panels (SIPS) and insulated concrete form (ICF) walls. See the Compliance Tab for related codes and standards requirements, and criteria to meet national programs such as DOE’s Zero Energy Ready Home program, ENERGY STAR Certified Homes, and Indoor airPLUS.ĭouble-stud wall construction is one option for high R-value walls. ENERGY STAR requires that insulation fill the entire wall cavity and that insulation cover the interior studs to an R value of at least ≥R-3 in IECC Climate Zones 1 to 4 or ≥R-5 in IECC Climate Zones 5 to 8 ( ENERGY STAR 2015).Completely fill the entire cavity of the double-stud wall assembly without misalignments, compressions, gaps, or voids.

Was the dirt needed elsewhere? Or were they make-work public works projects during economic downtimes? In short, what was the point? After all, the car parks were surrounded by imposing concrete walls, ramps were constructed to gain access even the floors were concrete to neutralize the elements.Construct a double-wall consisting of two framed walls forming a wide wall cavity for more insulation in the home’s exterior walls. Some might regard this as simply an accommodation of differing needs for different times, whereas others might wonder how necessary it all had been-why, for instance, was it thought useful to render these car parks subterranean in the first place.

Doubtless, each project required an enormous amount of time, labor, and money, yet the end result was a configuration very much like that which had existed before one minute, one bead of sweat, and one dollar had been spent. Since then, much reconstruction (“urban renewal”) has occurred in the area, which entailed putting back just about as much dirt as had been removed earlier. These were not street level but were laid out 15 to 25 feet below the streets, and thousands of cubic yards of dirt had been removed to create these. “Considering the enormous output … of theories concerning the Assyrian kings and their chronology-by far the greater art of which has proved untenable in the light of later discoveries and most of which, as we can see now, might well haveīeen avoided by refraining from premature speculation …Īs I was growing up-when the automobile was becoming a standard accoutrement-two large car parks were in the downtown area of the city where I lived.
