A roof coating is the top layer of a composite roof membrane and the system underneath. The coating needs to be durable and flexible (being able to deal with the shrinkage and expansion of the underlying structure).
Mineral fillers can improve the performance of the roof coating:
- By supporting the IR reflection in order to keep the temperature of the underlying room/building low, thereby reducing the energy consumption and costs.
- By providing resistance towards UV and thereby improving the longevity of roof coatings.
