New, improved ridge pan!

The TOPGREEN ridge pan is used when greening gable roofs because this special building component guarantees the right transition/connection to the roof surfaces coming together on the ridge. Mounting the correct vent pipes allows the circulating air on the ridge to escape between the green roof pan and tensioned sub-membrane. The air circulation also makes sure that the zone between the pan and tensioned sub-membrane is always kept dry.

The new ridge pan has deeper substrate and water storage chambers. This has the advantage that more nutrients and water for the plants can be stored in this area which is most affected by the wind erosion. The sedum mats can roam deeper into the chambers of the ridge pan and the risk that substrate and planting in this area being flushed out and blown away by rain and wind is significantly reduced.

For the first time, you will be able to inspect the new ridge tile from 20th to 23rd of February 2018 at our booth (Hall 8, Stand 8.503) of Dach + Holz International in Cologne.


In a time of major climatic changes it is becoming increasingly important to build in an environmentally friendly way which preserves resources. The TOPGREEN green roof system from atka makes an important contribution to this objective. Professional roof planting restores to nature vital green areas which have been lost because of building. Harmful materials are bound and filtered, rainwater retained and heavy downpours flow away evenly.

Green roofs also stand out for their excellent heat insulation in comparison to a conventional tiled roof. They also absorb annoying airborne noise and protect your home against potentially harmful weather effects such as ice and hail.

The TOPGREEN green roof system can be installed on both flat roofs and pitched roofs with an inclination of up to 45°, setting no limit on creativity, either for the renovation of existing roofs or the construction of new houses with an environmentally friendly green roof. Under a green roof, this creates a calm and relaxing atmosphere, which has a soothing effect on you personal well-being.
