Fire Door

Suppose a fire breaks out in your business building at 2:00 AM. Your fire-rated doors are working just as hard as your sprinklers and alarms. They keep flames and smoke in for long enough for everyone to get out safely. But most business owners don't think about the ratings of their doors until an inspector comes by with a clipboard and a serious look on their face.

It's not enough to just know about commercial fire doors; you also need to know how to choose the right ones that could save lives. If you give something the wrong rating, it won't protect you well enough. If you provide too much detail, you'll waste money that could be used for something else. To get it right the first time, you need to know what those ratings imply and when you need them.
