Florida Building Code TAS 201 is a crucial regulation, right up there with Virginia Plumbing Code 408.3, which says that your bidet spray can’t be any hotter than 110 degrees Fahrenheit. Rather than regulating the temperature of a water spray, TAS 201 is the impact standard for windows and shutters in Miami-Dade county, and if your window passes the test, it’s about as strong as they make ’em.
To figure out if a window is impact-rated, you’re going to need some impacts. And that means breaking out the lumber cannon. To pass the large impact test, a window has to survive a hit with a nine-pound 2 x 4 flying at 34 mph (50 feet per second). It’s then forced to withstand 9,000 pressure cycles—as in, wind pummeling the outside of the house while pressure varies wildly inside. The wind rating can vary, but Florida’s Best windows has a model that’s rated to 290 mph winds. At which point, you probably have bigger concerns than your windows.
There’s also a small-impact standard, which replaces the 2 x 4 with 10 ball bearings fired at 50 mph. But really, the large-impact test is where it’s at if you enjoy watching lumber cannons in action. We may sometimes gripe about building codes—maybe you like 115 degrees on the bidet—but if Irma keeps tracking toward Southern Florida, Miami will be glad for TAS 201.
