During a safety audit we noticed that people often underestimate how walls and doors interact during a fire. It raised a key question: when a structure promises one hour of resistance, how important is the actual door rating in 1 hour wall for ensuring the whole barrier works as intended?

From my experience on retrofit projects, the discussion about aesthetics and materials usually comes first, but when reviewing protection standards the door rating in 1 hour wall becomes the decisive element. Without it, the wall cannot deliver the promised resistance, and once included, the overall evacuation strategy suddenly feels complete and trustworthy.
