Doors and windows allowed in a fire wall are referred to as:

The main idea is that openings in a firewall must be safeguarded with fire-rated assemblies so the wall’s fire resistance isn’t compromised. Doors and windows allowed in a firewall are called protected openings because they’re enclosed by fire-rated components (like fire-rated doors or windows with proper frames, seals, and closers) that preserve the wall’s rated fire resistance. This protection ensures that the firewall still acts as a barrier between spaces even where there are openings. The other terms aren’t standard for this concept. Fire wall openings describes the feature itself but doesn’t imply any protective measure. Rated openings isn’t a typical designation for openings, since the protection comes from the enclosing assembly, not the opening alone. Resistant openings isn’t standard terminology either.
