The use of lattice grids on green roofs allows for natural air filtration. The vegetation on these roofs absorbs carbon dioxide and removes pollutants from the surrounding air. As a result, the greenery acts as an air purifier, significantly improving the quality of the environment around buildings. This effect is particularly important in combating air pollution, especially in urban areas where this issue is often noticeable.
Improvement of air quality
Green roofs effectively improve the thermal insulation of buildings. The vegetation, an integral part of these roofs, acts as an additional insulating layer. This reduces heat loss in winter and maintains moderate temperatures inside the building during the summer. This additional insulation contributes to energy savings and increased energy efficiency, which is beneficial both for the environment and for the building's occupants.
Thermal insulation
Perforated grids on green roofs play a crucial role in retaining rainwater. Thanks to their special structure, they effectively collect rainfall and then gradually release the accumulated water. This process supports the natural water cycle, which is particularly important in urban areas where a large part of the surface is paved. Significant reduction of flood risk is an important benefit associated with green roofs, especially in the context of urbanization.
Properties of GREEN SYSTEM grids:
1. Lightweight:
- Eliminates additional load on the roof structure.
2. Modular construction:
- Quick installation of the geogrid, and easy expansion even in the case of complex roof geometries.
3. Recycled materials:
- Made entirely from recycled PP PE plastic, in line with sustainable development principles in the choice of building materials.
4. Environmentally friendly:
- The construction material is environmentally neutral and groundwater resistant, and it is resistant to acids, salts, ammonia, and alcohols.
5. Biologically active surface:
- 85% of the geogrid surface is biologically active, meeting the requirements of building regulations for dense development.
6. High load resistance:
- The GREEN SYSTEM geogrid exhibits impressive load resistance – 300 tons/m2 (without filling) and 1000 tons/m2 (with filling).
Water retention
The GREEN SYSTEM can serve as a retention tank in roofs with a blue-green character. After heavy rainfall, water is retained in the tank and gradually drained away using gutters. Additionally, the GREEN SYSTEM can be used for watering plants, allowing for the reuse of water from the roof for garden irrigation.
The GREEN SYSTEM grid is placed between the waterproofing layer and the vegetative substrate on the green roof. Its application creates an empty space necessary for water retention in the internal drainage system of the green roof. During heavy rainfall, the efficiency of the GREEN SYSTEM can reach up to 80 l/m2 when using a single layer with a height of 10 cm. A thicker substrate layer and vegetation result in greater water retention. The runoff coefficient for the grid with vegetative filling on a level surface ranges from 0.23 to 0.31.
The GREEN SYSTEM grid was created with the idea of constructing green roofs with varying degrees of intensity. It encompasses both lush vegetation and more minimalist designs.
