Summary:This paper reports on a study of the movement behaviour of insulation in warm deck flat roofs. The observed amount of movement in response to diurnal temperature change and the relationship between temperature change and amount of movement varied depending on the type of insulation used and on the mode of attachment of the insulant. Long term irreversible movements were also revealed by the monitoring programme. These non-thermal effects were of particular significance with extruded polystyrene insulant where a gradual increase in gap width between insulant slabs was observed. The implications of these observations for flat roof design are discussed.
