AbstractThermal performance plays a major role in determining the success or failure of a roof system, and it can be controlled to a high degree by the designer. Thermal considerations in the design of roofs can be divided into two general categories: control of heat loss and heat gain of the space below the roof, and the effects of extremes and variations of temperature on the roof system. In Canadian buildings where temperature control through winter heating and summer cooling is common, heat gain and heat loss are of economic importance. Some roofs may only control heat gain by providing shade from the sun, but all roofs exposed to the weather experience wide variations of temperature. The effects of extremes and variations of temperature are of major importance because they influence the durability of the total roof system.
