This Material Protects Homes. Why Don't US Builders Use It?

A building material called a 3D cementitious sandwich panel is made of fire retardant foam sandwiched between two wire mesh faces. The two faces are connected with reinforcement wires that run through the foam and the whole thing is enveloped in concrete. If built properly, it's very strong, and can withstand high winds, earthquakes and even fires. A start-up called RSG 3-D wants to bring this technology to the masses in the U.S.
There's a building material that could keep houses intact during hurricanes, earthquakes, tornadoes and fires. While it's been widely used around the world, the U.S. is a laggard in adopting the construction technique.
One company trying to change that is RSG 3-D, which is bringing a building material known as 3D cementitious sandwich panel for mass production in the U.S.
"Housing economists will tell you that 77 percent of homes built in the United States are at extreme risk for some type of natural disaster," said RSG 3-D CEO Ken Calligar. "The East Coast is primarily hurricane, the Midwest is tornadoes, which we will also survive, the Rockies and the West are wildfire plus seismic events. We are resistant to all of that."
Last year was the costliest year on record for climate disasters in the U.S., with over $300 billion in damages, according to NOAA.
Each panel made by RSG 3-D consists of fire retardant foam sandwiched between two wire mesh faces. The two faces are connected with reinforcement wires that run through the foam and the whole thing is enveloped in concrete.

This Material Protects Houses. Why Do US Builders Avoid It? | CNBC

[@richardsims6095]

The system was invented in California in the 60s. It was first patient in the early 70s. 2 hour fire rated, 250 wind load, 9.0 seismic rated. Oh 70% more energy efficient than traditional wood homes. More efficient than SIP or ICF due to thermal mass.

[@georgesararu9945]

Are you sure about that? Your code only show A,B, and C, rating for seismic. and the entire certification expires this month! Did you renew it ?

This will be the system I use for a single story house in Florida on the Atlantic coast. Plan to move in a year or so after I buy land during the impending Great Recession. Will add a rooftop deck and BBQ with an elevator and firepole. Hope to make it on the cover of Architectural Digest. Wish me luck.

[@RobbsHomemadeLife]

I am reading a lot of negative comments here. Habitat for humanity built several of their homes using this material in Homestead Florida. They were built right before hurricane Andrew hit. Homestead was Ground Zero. The Habitat for Humanity houses survived hurricane Andrew when other houses in the neighborhood were demolished. The roof and walls are one solid piece. There is no little tile or molding to come off the roof and become a weak point and have the wind get under it and tear the house apart. It doesn't make sense to build a house with a roof made up of hundreds of little pieces. SCIP panels survived a category five hurricane. They don't burn. They don't rot. They have been around for 40 years. It kind of makes you wonder why no one is making houses out of them.

[@doctordemento965]

This isn't new building material. In fact, it's behind the old hadite block with rebar and foam structures that were made decades ago. You know what happens when a tornado hits those... and they are stronger.... they got demolished. Tornadoes will bend beams in a skyscraper. Another thing they have yet to prove is the actual PROOF this will survive a cat 5 beach hurricane. That's a whole different ball of wax than straight line sustained winds.

It is not just the building technology, it is the method to construct it. The most precision is attained by off site factory built construction of homes. They have been around for years but now this has been perfected to be mass produced to surpass standards. This is not the only technology but existed since Jimmy Carter brought it to Habitat for Humanity. But instead of congress adopting such into law, the building industry as usual lobbyed against. However, now these and many other technologies will and are making a big difference in the construction world. Saving lives and property. Japan, Sweden, Finland, and Netherlands and many others invented disaster proof techs.

the answer is pay attention and have your house done by prefabcompanies who use all the various advanced techs. I am aligned with companies who are saving lives and educating that disaster is not necessary but America is still ignorant. Each region requires different things. Do not do it yourself and but go to the experts and stop trying to guess what is best. There is no best. Concrete is being used, along with this material, seismic prevention is done differently. Scandinavian countries got in early but America always puts profit first instead of doing things that durable.

[@tealkerberus748]

House fires often start from furnishings such as electrical goods which are not part of the building structure. It's nice if the building won't fall down, but if the smoke killed all the people inside they're just dead in a building that didn't fall down. There are always alternatives to building your house full of synthetic foam, kids. All that reinforcing mesh is great, but you can do better than filling the gap with toxic waste.

Even if wood is abundant, the average house made from wood is still expensive for most people to afford. People spend their lifetime paying mortgage when wood homes don’t last long and require a lot of maintenance as they get older. Inflation and demand has raised the cost of wooden homes even more. Home insurance costs have gone higher. People can’t afford flood insurance. These wood homes can not stand tornadoes, hurricanes, flooding, and go up in flames easily if fire. People who lived centuries ago lived in better houses than we do. You can still see ruins and remains of houses build from centuries ago. They used better material. The US really needs to learn and make a change. Give the common man a house made from material that lasts for generations. And stop cutting the forests no matter which part of the world. Stop cutting trees. They are much more valuable than making a house out of them.
