Green roofs

dachtechnik.pl › Green roofs

Both the investor and the environment benefit from a green roof:

- it increases the service life of coating by minimising external influence, i.e. UV rays, temperature, snow and rainfall, ice, etc.

- it enhances the acoustic properties the partition wall,

- in the summer it helps to maintain a comfortably cool temperature inside and decreases the costs of air-conditioning,

- in the winter it acts as an additional insulation decreasing heating costs,

- precipitation water is absorbed by the substrate which slows its run-off and decreases internal and external loading of drainage systems,

- greenery with substrate positively affects the micro-climate by absorbing and filtrating harmful substances,

- and lastly: a green roof is much more beautiful than any regular flat roof.

 

POBURSKI Dachtechnik’s experience shows that only implementation of a complete greenery design including all roofing layers in accordance with EN / PN / FLL (Forschungsgegesellschaft Landschaftsentwicklung Landschaftsbau) / IFD (The International Federation for the Roofing Trade) / IFBS (The Industrial Association for Metal Building Constructions) and DAFA (Association of Flat Roofing and Facade Contractors) standards guarantees its future service life and quality. Separating the implementation of flat roof insulation from greenery may often lead to negative results.

There are two basic types of roofs: intensive and extensive greenery roof.

 

We would like to present you the basic rules allowing the design and implementation of a flat roof with greenery:

1. Due to high mechanical loading at the hipped ends of the roof designed for cultivation or greenery it is necessary to place high-quality anti-water insulation.

 

2. The insulation system (building wrap, thermal and anti-water insulation) should be designed and implemented in a way so in case of leakage water diffusion will not take place, eventually, the leakage point would be easy to locate. It is possible, thanks to complete glueing of the roofing structure or partition with bulkheads of the roof’s individual surfaces.

 

3. Slopes designed for insulation should be slanting in the direction of water drainage points. In the case of intensive greenery in connection with drainage through water dump-up, it may be required to configure anti-water insulation without slanting.
