A Fire Door Is An Assembly
The specification is not just FD30S or FD60 on paper. The hinges, latch, closer, intumescent strips, smoke seals, frame and installation gaps all affect performance. That is the core idea this page now leads with.
Where Specification Mistakes Happen
Common mistakes include the wrong hinges, missing seals, closers that do not suit the door, over-trimmed leaves and worn frames being treated as “good enough”. Specification pages should help stop those mistakes before ordering.
