ONDUGREEN creates extra living and functional areas in full nature.

Fast urbanization in the cities all over the world has resulted in the loss of green lands. Natural surroundings that should normally exist have been replaced by concrete buildings. Air pollution has become a major worldwide problem.

The Green Roof system helps twice to protect the environment: by using recycled products on the one hand relieving disposal sites and on the other hand giving nature the chance to reconquer space in the crowded cities. Apart from the attractive appareance of a Green Roof there are also a lot of solid economical and ecological benefits, provided that there is a technically perfected Green Roof build-up which guarantees a durable success. Green Roofs are worth being installed from small surfaces on garages or car ports up to large industrial surfaces.

Every year, natural surroundings are sacrified in favour of urban developments whereas Green Roofs constitute the ideal solution for offsitting the loss of nature. That is why we have found in technically innovative and practicable solutions for integral use of the roof- from the so called extensive landscaped roof as an ecological protection layer up to beautiful “Roof Garden” which can be combined with footpaths and road surfaces. To compensate the functions of the missing ground is the main requirement in view of establishing a durable vegetation on roof surfaces. Technically perfected Green Roof Systems from ZinCo Ingenieurwerkstatt + Gruendachsysteme combined with the experience of Onduline Avrasya in the roofing systems guarantee a durable success of landscaped roofs.


Advantages of Green Roofs


ondugreen 3A- Reduced Sewer Cost

A Green Roof build-up reduces the water run-off to 50-100 %. The remaining water flows off with a time difference. So, with Green Roofs, it is ensured that the rainwater remains in the natural water cycle thereby reducing sewer cost.


ondugreen 4B- Reduction of Dust

A Green Roof helps to filter the dust particules in the athmosphere. The nitrates and other environmentally harmful substances on the air or the rainwaters are absorbed.


ondugreen 5C- Reduced Noise Level

Due to the soft plant level of Green Roofs there is sound absorbtion instead of sound reflexion. Moreover, the sound insulation of a building can be reduced up to 8dB.


ondugreen 6D- Additional Spaces

Roof gardens offer additional space for leisure activities without spending money on new and expensive building grounds.


ondugreen 7E- Reduction of Urban Heat Island Effect

The surfaces of green roofs improve the microclimate by cooling and humidifying the surrounding air. In addition the plants capture solar energy, extract carbon dioxide from the air, and combine it with water to produce organic substances. Through this process, plants release oxygen which guarantees more purified air.

ondugreen 8F- Reduced Renovation Cost

The waterproofing’s life expectancy is increased, because it is better protected from UV-rays, hail and extreme temperature differences. It can be presumed, that the life expectancy of waterproofings is increased to more than 40 years if a green roof is installed.


ondugreen 9G- Reduced Energy Cost

Thermal insulating green roof build-up with official property values are allowed to be added to the conventional thermal insulation. Due to this special build-up, the building owner saves up to 50 % of the energy cost.


ondugreen 9H- Natural Habitat for Animals and Plants

At least a part of green surfaces which were sacrified to building developments can be compensated by landscaped roofs, thereby reducing the quantity of sealed surfaces and encourage limited wildlife development.
