- Abstract
- Different types of external additional insulation systems, applied to facades of multi-storey buildings, were tested on a full scale with respect to their fire hazards. The facades were exposed to flames and hot gases emerging from a window opening in a single fire compartment. The increased risk of fire spread along the facade and through the windows in the storeys above was studied. The test house has a load bearing structure of steel and walls, ceiling and floors of aerated concrete. The building is three storeys high with one room on each storey. The compartment fire was arranged in the room on the first floor. The additional insulation systems were applied to the front facade, made of aerated concrete with a density of 700 kg per m(3). The fire load, chosed for the tests, corresponds to a probability in excess of 20% in the Swedish statistics for living-rooms. This means a fire load density of 110 MJ per m(2) of total surface area of enclosure. The test fire roughly simulates a real fully developed fire in flats and offices including modern furnishings with components of synthetic material (plastics), during approximately 10 minutes.
