Green roofs and roof gardens have become a worldwide trend for more than a decade ago, in the central urban areas, where there are few green spaces. In addition to aesthetic values, roof garden has ecological functions such as improved protection against heat and cold, noise damping, improving microclimate conditions through evaporation, rain water retention, reduces the load during heavy rains, the protection of the waterproofing of the roof and so on.
Gras Garden is official distributor and authorized contractor of ZinCo – one of the leading manufacturers that are pioneers and innovators in terms of extensive and intensive roof greening. In its close collaboration with scientific institutes, ZinCo has acquired the fundamentals for its special competence in the development and production of green roof system build-ups, which is reconized worldwide today. Safeguarding high quality standards is closely related to ZinCo‘s international commercial experience over several decades. Safe and reliable system build-ups by ZinCo are investment in long-term building preservation, and their functional benefits are persuasive.
Green roofs are divided into: extensive and intensive, depending on the way of use, depth of the substrate, and species that will be planted. In order for the roof garden to be stable and long-lasting, it is essential to build multi-specialized layers. Basically, those layers are:

Drainage foil panel
Drainage foil panel is specially designed for green roofs because it has the ability to delay rainwater, avoiding its retention and protecting the waterproofing system. The panels have a high load resistance and are suitable for creating all types of green roofs: extensive and intensive.
Specialized substrate
In order to make roof structure long-lasting and stable is of utmost importance that to set up specific substrate for this purposes as the last layer. Our team uses a substrate which is composed of volcanic stone, specializes peat, humus substances and sand. An important feature of the substrate is that it has a lower specific weight, which goal is to List minimize load on the object construction. This substrate has a well-balanced water-air regime, which ensures the proper plant growth and development in the specific conditions of the roof garden.
