Abstract
A roof construction-suspended ceiling system consists of a watertight outer layer and a layer of thermal insulation beneath it resting on a metal roof-supporting surface that has a vapor barrier. Below this there is a suspended ceiling system that has insulation placed thereon. The suspended ceiling has openings that will vent the area between the roof construction and the suspended ceiling and the above-said openings may be quickly closed in the event of a fire below the suspended ceiling system.
