Roof construction in the form of a counter-flow roof, where air is taken in from outside and into a room (2) between an airtight outer roof (1) and a heat-insulated and air permeable inner roof (3), which prevents the insulation (3) from being destroyed in the event of fire and that the amount of air which can pass through the inner roof (3) is limited by the temperature, which the air is allowed to have when it flows into the underlying pause room, through the inner roof (3) being supported by a load bearing and fire protective plate (4) which is air permeable.<IMAGE> |
