Fire Rated Frame Filling consolidated into one approval
The requirement of whether back filling of frames is required or not has been on the agenda for some time now. In 2015, Pyropanel took a position to only recommend that all pressed metal door frames are backfilled. Whilst this provided direction to instilling industry best practices, it did create more questions as to how to properly back fill a frame as per fire test and how that frame is connected to the walling system. This is becoming a significant compliance issue on new projects.
