AAC (Autoclaved Aerated Concrete) is a product that could be utilized.

Here is one supplier: http://www.e-crete.com/

AAC can be cut, drilled, nailed, grooved, routed, shaped, sculpted, carved, coated, floated, screwed into and milled with common tools. AAC anchors can be hammered directly into the block work and AAC fasteners can be utilized for a wide variety of commercial and residential decorating applications.

AAC has exceptional thermal insulating qualities. An E-Crete wall provides solid insulation, without the thermal bridging (cold spots) associated with through-wall framing members or fasteners.

Buildings constructed with E-Crete tend to be cooler in summer and warmer in winter. As a result, the building's air conditioning or heating use may be lower and makes the use of additional thermal insulation unnecessary. Customers reported lower utility bills.

In addition to greatly moderating the interior temperature, this lag time allows energy consumption to be shifted to off-peak hours, a benefit to power companies. In many temperate environments, an 8-inch-thick AAC wall provides more than the required thermal protection without additional insulation. Better temperature and humidity control provides greater comfort for building occupants.

A test was done on a 10" AAC wall. The outside of the wall was painted black to maximize heat absorption from the sun. A thermometer was placed on the exterior and interior surfaces of the wall to measure its temperature changes over a twenty-four hour period. The exterior surface fluctuated over 126 degrees farenheight while the interior surface fluctuated only +2 degrees farenheight.

wow--thanks for the link, Paul. It almost seems like a miracle product.

Is the UA 2.0 far behind?

Bringing this thread forward post-outage.
Keywords: Pieper, Arthur, Paradise Valley, Usonian Automatic

Also, links to other pre-outage threads on Pieper and the Charles Montooth house next door which is often mistaken for Pieper:
