NEW! The Completed Book is Now Online!

David B. South, President of Monolithic, has plenty to say on the subject of Polyurethane Foam. What began as a fascination in 1969 turned into bread and butter by 1971. By 1974 David and his younger brothers, Barry and Randy, owned and operated the largest spray-foam business west of the Mississippi. That same year, Souths, Inc. sprayed as much foam as all the other know polyurethane companies combined.

Understanding Polyurethane Foam Density

Foam As A Fire Barrier
	Urethane foam is an excellent fire barrier when used on the exterior of a building. There are numerous examples of urethane foam roofs saving a building from fire. Burning brands, that can include anything from hot embers to large pieces of burning wood, can lay on a urethane roof for a considerable time before burning through.

Insulated Footings
	The best way is to insulate your footings is to spray foam on the exterior of the footing after the dome is built. Spray polyurethane foam two to three inches up onto the exterior of the dome and down over the concrete at least eight to ten inches into the ground. The foam will have to be coated to be protected from sunshine.

**Polyurethane Foam Application--Do it myself or hire a contractor?**
This article could be given to a foam contractor so expectations are clear. Always check references! If you plan to start a dome building business, purchasing a foam machine is advisable. If possible find a foam machine that includes training.

Rebar Hanger Placement and Final Foam Application
	Rebar hangers are 2-inch square thin steel base plates with a wire welded perpendicular in the center and barbs protruding the opposite side from the wire. These barbs are pressed into the initial 1.5 inches of foam -- before the layers of foam are applied.
