Hollow blocks used with 3-D panels can save California houses from wildfires.

Meanwhile, the Woolsey Fire in Los Angeles and Ventura countries have destroyed over 500 homes and scorched more than 98,000 acres. A building material known as a 3D cementitious sandwich panel could have saved some of these homes. It can be combined with hollow blocks to build buildings.

A wood structure will combust almost immediately and studies show that once a wood structure has 4 or 5 percent of the building on fire, it becomes a total loss because there’s no stopping the fire,” said Ken Calligar, CEO of RSG 3-D. It is the company bringing the panel to the U.S. for mass production.
