A sophisticated system comprising different components compensates the functions of the area of ground that is missing and guarantees a durable plant covering on rooftops
1. Root Barrier: Protects the waterproofing of the roof from penetration by plant roots.
2. Moisture Retention / Protection Mat: Protects the root barrier from mechanical damage, as well as retaining water and nutrients.
3. Drainage Layer: Retains rainwater in troughs on the upperside, whilst the surplus water is safely drained away. Necessary ventilation to the root area is also guaranteed.
4. Filter Sheet: Prevents fine particles from being washed out of the substrate soil, thereby ensuring the efficiency of the drainage layer.
5. Vegetation Layer: The mineral substrate ZinColit® and the ZinCo system soil ensure that the vegetation layer is ideally suited to the needs of the green roof in question.
6. Plant Level: Drought-resistant and robust plants like sedum-species up to demanding shrubs, bushes and even trees.
Extensive Green Roofing
Extensive landscaped roofs are an ecological alternative for conventional surfaces like gravel roofs and their installation and maintenance costs are only marginally higher. Suitable plants include types of moss, Sedum species, herbs and some grasses.
Intensive Green Roofing
When most people think about intensive landscaping they think of well-kept gardens on used roof areas. However, with the relevant ZinCo system superstructure, you can achieve almost anything you want.
A semi-intensive roof is the ideal solution when the roof is visible and needs all-year-round colour. Semi-intensive roofs are also suitable for recreational use and can include paving and patios. Limited but periodic maintenance and irrigation are required.
Thanks to bioplastics, drainage element, protection mat and filter mat in this system green roof build-up now contribute materially to climate protection, in addition to their actual environmental function.
Stormwater Management Roof
Changing weather conditions (e.g. extreme local rain events) can result in an entire public sewerage system being overwhelmed. One of the great benefits of a green roof is that it detains water and allows for the time-delayed run-off of stormwater (water retention).
Urban Climate Roof
The sealing of former natural surfaces continues unabated, which is significantly influencing warming in urban centres. As a result, global radiation is used in a totally different way. On sealed surfaces, it can no longer be used as an engine for plant growth and can therefore hardly be used for evaporation for cooling.
Rooftops are being used holistically at an ever increasing rate. And this makes sense: everything that can be planted at ground level can also be planted on a rooftop. The correct technology must be applied to ensure that paving slabs built on rooftops are durable and function correctly.
Green Roofs and Solar Energy
Photovoltaic systems and green roofs offer a winning combination: The cooling caused by evaporation at the plant level ensures a favourably lower ambient air temperature for the photovoltaic cells, which in turn improves their performance.
When working on rooftops – and this includes maintenance work on green roof areas – personal safety equipment is to be used wherever risks cannot be avoided or suitably limited by safety measures like, for example, railing.
