Nearly every building causes the soil to be sealed, impairs natural water circulation and fills the sewage system with additional rainwater. Green roofs store a large proportion of precipitation, make a valuable contribution to the ecological balance and are also an intelligent alternative to the additional load of pebbles or tiles on a flat roof.
Cool in Summer, Warm in Winter
Green roofs guarantee improved inside temperatures in three ways at once. The drainage layer, substrate and vegetation reduce the impact of the sun. Adiabatic cooling, i.e. the evaporation effect in the green roof, also causes the roof temperature to drop. Instead of having a temperature of 80˚C (176˚F) or more, the roof may have a temperature of only 30˚C (86˚F) and inside temperatures stay lower for longer. In winter, the overall inherent better K value of a green roof ensures that less heat is lost through the roof and therefore results in reduced heating costs.
Nature: above and below
EPDM rubber is a virtually natural material, ecologically harmless and environmentally compatible. In contrast to many other roof sealing systems, NOVOtan® Ecotop does not contain any volatile softeners and therefore permanently maintains its excellent elasticity. For example, some bituminous seals have three layers, whereas NOVOtan® Ecotop is made of only one layer, it is a robust sheet, seal and protection against roots all in one and contains no root poisons. Proved by more than 25 years of practical experience.
