After being introduced in the early 1950s, Breeze Blocks quickly became ubiquitous in the hot desert climates of the southwest. They act as a screen encouraging airflow while blocking the heat of the sun. These were used as design elements by both the homeowner and in commercial and public buildings. There are over 250 patterns. They reached their height of popularity at the 1964 New York World's Fair. There were so many buildings using Breeze Blocks there that they quickly lost their cutting-edge vibe and fell out of favor.

Even so, they enjoyed a good 10-year reign.

Concrete blocks were not new (think FLW), but the airy Breeze Blocks of the 1950s were a variation of the Shadow Block and took this simple and affordable architectural feature to new sophistication.
