This paper surveys the factors governing the design of insulating concrete roof decks. Factors affecting design considerations are multiple, ranging from aesthetic to technical. This paper deals only with the technical design considerations of roof deck systems made of steel centering or forms with a low-density concrete overlay. This type of concstruction represents the majority of low-density concrete roof deck usage, other than concrete used for roof fills.
