Fire rated frames and doors play a vital role in keeping people safe and minimizing property damage during a fire. In fact, there has never been a loss of life due to a properly installed and maintained fire door. Hollow metal is the only door material widely available with a 3 hour label.
There’s a lot to learn when it comes to fire rated products. SDI has developed a variety of resources for architects, specifiers and distributors. The “Fire Rated Assemblies” presentation is a good place to start for a broad primer.
Don’t mistake a fire rated door frame or fire rated doors with fire proof doors; they are not the same thing. Get more info and SDI certified manufacturers.
