The colorful roofs of Ecodak
Due to its sustainable nature, an eco-roof increases the value of a building and enhances the livability of its surroundings. An eco-roof offers a quick return on investment. In short: an excellent investment.
Joosten Ecodak’s expertise goes beyond green roofs with vegetation. Increasingly important are blue roofs for water management, yellow roofs for energy generation, white roofs for mitigating the Urban Heat Island effect, grey roofs designed for traffic use, and red roofs to optimally utilize expensive square meters for recreation… or a combination of these.
