One of the items in my discussion on the fires in LA, I posted that there are problems with building homes out of fireproof materials. Someone asked what that could be, and I would like to expand on that a bit. Let me begin by saying that I am not an engineer, so I will be giving you a firefighter’s perspective on this, meaning that my knowledge is broad but shallow on the topic.
Building homes to be entirely fireproof has long been a goal. Attempting this is how we wound up with things like Asbestos. One of the things that was tried in the wake of the Chicago fire in 1871 was to build homes with a fireproof roof. In the aftermath of that fire, a great many homes in the US were built with slate roofing tiles. It appeared as though the problem was solved. No more would fire brands land on your roof and burn down your house.
Until 1900, when a hurricane struck Galveston, Texas. The storm was estimated to be a Category 4 on the Saffir-Simpson scale. The winds of the storm, estimated to be over 140 miles per hour, ripped those slate tiles from the roofs of the homes, and many people were killed by these flying stone axes.
It’s difficult to find building materials that withstand all conditions, and when you do, those materials make building homes prohibitively expensive. Even were one to build homes like that, the radiant heat coming through the glass of the windows will ignite materials inside of the house.
It is still a cheaper and easier solution to manage forests, create a defensible space around your home, and take other preventative measures. The issue is that people who move to “the country” like having the woods and other plant materials growing right next to the house.
