Optigrün ECONOMY ROOF

With a SAVINGS ROOF, even large roof areas get an easy-to-maintain green roof with simple means. It is the most cost-effective green roof structure in terms of material, installation and maintenance and comparable to a gravel roof in terms of weight. Within the framework of the encroachment compensation regulation, a SPARDACH is a simple and cost-effective mitigation measure and contributes to the fee reduction for municipalities with split wastewater charges.

Like all Optigrün system structures, the SPARDACH also meets the requirements of the FLL green roof guidelines.
