Compartmentation and penetration sealing

Fire-resisting boundaries work only when doors, cable penetrations, joints and later changes preserve the intended compartment.

How it works

Use rated construction and protected openings to limit fire and smoke spread for the adopted building and fire strategy.

Where it fits

Reference discussions with the design team and authority having jurisdiction about spaces and failure containment.

Where it breaks

A generic card is being used to specify a rating, product, assembly or local compliance path.

Tradeoff register

  • Limits physical spread
  • Depends on every opening and change
  • Adds inspection and documentation obligations

Interactive teaching model

This card connects to the fire lab. Its output is a bounded calculation or an illustrative directional model, not measured site data or a commissioned design result.
