Waterproofing green roofs with Alwitra
Green roofs are right on trend. They bring nature to the rooftop and contribute to improving the ecological, functional, and aesthetic quality of living and working environments—especially in cities. Kauz Bedachung uses Alwitra root-resistant membranes for this purpose.
Green roofs are more than just beautiful.
They offer ecological and economic benefits:
- Improved microclimate
- Additional habitat for plants, animals, and people
- Retention of dust and nutrients from the air and precipitation
- Retention of precipitation
- Protection of the roof waterproofing from UV rays and extreme
- temperature fluctuations
- Longer roof lifespan
- Improved thermal and sound insulation
- Reduced energy costs
- Improved quality of living
- Increased property value
- Funding support through special public programs
For green roofs, Kauz Bedachung installs products from the German manufacturer „alwitra“. The company specializes in waterproofing flat and low-pitched roofs. Its recyclable waterproofing membranes, „EVALON“ and „EVALSTIK“, have an exceptionally long lifespan —even under extreme weather conditions.
Other properties of the two membranes:
- Their light-colored, smooth surface repels dirt
- They are root- and rhizome-resistant and can be installed without an additional root barrier in a green roof system .
- They provide long-lasting reliability through material-homogeneous welding
- They offer high thermal and mechanical resistance (and are, among other things, walkable)
- They are extremely vapor-permeable—moisture can diffuse from the roof system into the outside air across their entire surface
- They are highly resistant to damaging (solar) radiation and reflect heat rays—ideal for cool roofs
- EVALON has up to five times lower fire load than two-layer waterproofing systems
- etc.
Types of green roofs
Almost all flat roofs can be greened, provided that the structural requirements are checked and the type of greenery is suited to the slope of the roof structure. Types of green roofs include:
- Intensive green roofs These include plantings of taller perennials and shrubs, and even trees—entire garden landscapes can be created.
- Simple intensive green roofs These are ground-covering plantings of grasses, low-growing perennials, and low-growing shrubs.
- Extensive green roofs These are naturalistic forms of vegetation that largely sustain and develop themselves. They include low-growing grasses, mosses, and herbs.

Vergessen wurde das Temperieren. Im Flurfunk habe ich gehört, dass solches Dach vor Hitzegut funktioniert. Die Begrünungsarten muss ich noch erst überlegen. Danke!
Die Seite weht nach der gewünschten Kühle! Die Idee mit der Begrünung hat mir die Freundin geraten. Erzählt wurde, dass solch ein Öko-Dach herrlich temperiert: im Sommer behält es die Kühle, im Winter die Wärme. Aufgefallen ist mir die Extensivbegrünung. Vielen Dank für die hilfreiche Anregung!
