This question-and-answer article about the choices of insulating foam board for use under stucco exterior finish on buildings, appears in full-text just below and quotes-from, updates, and comments an original article from Solar Age Magazine and written by Steven Bliss.
Question: "In-Town Solar Condos: One Developers's Plan Book" (Solar Age, 9/83) includes mention of an exterior insulation system for masonry walls using 2-inch urethane under stucco.
I have had little success locating such a system in Phoenix that uses polyurethane and not polystyrene foam insulating board on the building exterior.
Can you supply me with information on a polyurethane insulation system or any other exterior insulation that might give me a better R-value than 2-inch polystyrene foam insulating board? - James Hoffman, Tempe, AZ.
Answer: First, a clarification - strictly speaking the rigid foam insulating board used in the La Vereda Compound (the subject of the article) was a foil-faced polyisocyanurate foam insulating board (Thermax™), not a polyurethane.
Ann MacKinnon, office manager of LaVereda developer Communico, said that The company often used Thermax™ over concrete block walls and under stucco on buildings, as do most builders in the Santa Fe area.
Wire stucco lath is placed over the foam insulating board and attached to the masonry below using concrete nails. MacKinnon said that "a builder Santa Fe who didn't know and use this technique would probably be out of business" because demand is high for adobe-like finishes. She added that lath and stucco can be used over sprayed-on urethane foam insulation as well.

do you have information on how to detect roof leaks with a laser?
I'm not familiar with any laser tools that are used for leak detection. If however you meant infrared or thermographic equipment used for leak detection, those devices use infrared (heat sensors) not lasers.
IR and thermography are great ways to find ACTIVE leaks, based on the premise that the temperature inside a building cavity (stuccoed wall or under a roof) will be different (normally cooler) where there is moisture.
But watch out: leak detection methods like IR or thermography won't detect areas of prior leaks if the leaked-into areas happen to be dry at the time you are looking. That's one reason (among many) why relying on these tools alone is a mistake.
Without an accompanying expert inspection for visual signs of leaks or building construction details that make leaks likely we can't be confident that we have an accurate picture of the building leak history nor an accurate idea of where else there is likely to be hidden rot, insect damage, or mold contamination due to leaks.
