 Do frames and fire rated openings need to be labeled? That's a great question. Want to get all the time? Come on in and let's check it out. Welcome to Code Corner with Katie. I'll be basing my answers today off of NFPA 80 2013 edition since it is referenced by the International Building Code 2015 edition. Always make sure that when you're answering a code question, you have the addition that is being referred to either from your adopted state, the code, or the reference standard. 6.3.1.1 says that only labeled door frames shall be used. The label on the frame does not have to have an hourly rating like it did in days past. If it's a three-sided frame and it's hollow metal, then the label on the frame can just have the third party agency and the frame manufacturer. So for example, underwriters laboratory or Warnock-Hursey. If it's a three-sided frame or a transom side light frame, then it will have to have an hourly rating because that's based on the size of the glass. In later editions, the 2016 and later editions, they even go further to explain that a frame that's in a masonry wall is for good up to three hours, whereas a frame that's in sheetrock wall is recognized as good up to 90 minutes.
