Most technical provisions of the BC Fire Code describe how the code’s objectives and functional statements are achieved. However, some provisions, like this one, do not relate directly to a code objective. The following analysis is provided to assist in understanding of the provision.

  • practical construction limitations outweigh the need for thermal protection (garage doors),
  • thermally broken layers are inherent to the design (storm doors), or
  • other code considerations take precedence (required fire-resistance rating).
