Plancher haut

I've come across the term plancher haut in a set of fire regulations. The context is:

La chaufferie doit avoir un plancher haut et des parois coupe-feu de degré 1 heure.

Would I be right in assuming that means the floor directly above the boiler room (in other words, the boiler room ceiling) must have 1 hour fire resistance?

    so a "plancher haut," or high floor, means ceiling?
    In this case, yes. But the context is a technical document, so I doubt anyone would say it in normal conversation (more likely plafond). I also suspect it to have a slightly more structural role in the integrity of a building than a mere ceiling... Just a subtle difference (I suspect).
