There is an increasing interest in sustainable and environmentally friendly entrepreneurship, which is not surprising in this era of climate change. With a green roof or green wall, you make a good as well as a beautiful contribution to the environment. It also offers many other benefits. For example, calculations have shown that a green roof already pays for itself after 4 or 5 years through a reduction in energy costs.
Structure of a green roof
A green roof consists of the following layers:
- Watertight and root-proof roofing of two or three layers
- Protective layer against mechanical damages to the roofing
- Drainage layer of, for example, plastic or minerals
- Filter layer
- Substrate layer
- Vegetation layer
Systems in which multiple layers are put together exist, such as the buffer drainage mat, which also has a protective function.
