Green roof waterproofing with RESITRIX® EPDM roofing membranes

Reliable roof waterproofing for all green roof systems

The green roof segment harbours a great deal of potential and will become increasingly significant as climate change continues. Cities are expanding, and the global population is growing steadily. As building development increases, natural green spaces are clearly being lost, but this process can be supplemented with roof vegetation.

The positive effects that green roofs have on buildings, people and the environment above all else are therefore incomparable to any other building concept.

Our RESITRIX® SK W roof waterproofing membrane is compatible with every green roof structure, which means you are free to choose any vegetation manufacturer. RESITRIX® SK W is fully self-adhesive, hot air-weldable and also root-resistant according to FLL standards and DIN EN 13948.

Taking responsibility for the environment

RESITRIX® SK W Full Bond only contains ecologically safe components and no hazardous additives such as chlorine or plasticisers. RESITRIX® can be classified as completely non-toxic and, unlike other common materials or currently used roof systems, it does not release any chemicals into the atmosphere throughout its entire service life.

The life cycle analysis (environmental impact) of RESITRIX® can also be assessed as being very positive, according to an independent study (CREM study). All the relevant processes throughout the entire life cycle of RESITRIX® products were considered during the study. Taking the various fixation methods and the products’ long service lives into account, RESITRIX® is an eco-friendly choice with regard to its environmental impact. All RESITRIX® variants are recyclable, which ensures that we also meet our responsibility towards the environment in this regard.

Mit unserer RESITRIX® SK W Full Bond haben wir eine EPDM‑Dachabdichtungsbahn speziell für Gründächer, Dachgärten und Grün­dachsysteme aller Art entwickelt.

Types of roof vegetation

The most common green roof structures can be classified and distinguished as follows:

  • Extensive vegetation
  • Simple intensive vegetation
  • Intensive vegetation

Extensive vegetation

For extensive roof vegetation, grasses, moss, herbs, sedum and other hardy and regenerative plants are planted in the thin layers of substrate.

Extensive vegetation is an “ecological protective cover” which does not require a great deal of care and only needs to be watered during the root-taking phase.

  • Green vegetation: Moss, sedum, grass and herbs
  • Build-up: 6 – 20 cm
  • Weight: 60 – 150 kg/m2

Simple intensive vegetation

Simple intensive vegetation is a type of “creative vegetation” that requires an average amount of care and regular watering.

  • Green vegetation: Grass, herbs and small woody plants
  • Build-up: 12 – 25 cm
  • Weight: 150 – 200 kg/m2

Intensive vegetation

Shrubs, woody plants and turf in particular are used for intensive roof vegetation projects. Bushes or trees can also be planted intermittently.

Intensive vegetation creates an image of a “well-maintained garden area”. It requires a great deal of care, and regular watering must be ensured.

  • Green vegetation: Turf, shrubs, bushes and trees
  • Build-up: 15 cm – 40 cm and taller
  • Weight: 150 – 500 kg/m2

Basics

The versatile potential uses and positive properties of roof vegetation are becoming increasingly important around the world. This is true both from an ecological and economical standpoint and with respect to building physics.

Overheating in towns and cities

Too high a degree of sealing and waste heat given off by traffic, industrial premises and domestic fuel mean that city centres are turning into “urban heat islands” (i.e. suffering from what is known as the “urban heat island effect”). The fact that these areas don’t even cool down at night is increasingly harming the health of the urban population. Green roofs can cut the energy surplus and make the urban climate more bearable by means of absorption and water evaporation. Vegetation on green roofs can improve the quality of the air in the long term. It is only due to the roofs’ vegetation-based surfaces that numerous pollutants are filtered out of the air.

State funding

Many cities and municipalities are promoting roof vegetation in a variety of ways. The promotional measures range from attractive financial subsidies and roof vegetation being recognised as an ecological compensatory measure, to the inclusion of roof vegetation in building development plans.

Energy efficiency

A building’s energy footprint can also be improved in the long term with a green roof. Nowadays, there are a variety of green roof systems which have an offsettable level of thermal resistance and which can therefore be included in the structural calculation to ensure compliance with the Energy Saving Regulations (EnEV).

Benefits of green roofs

Green roofs meet the most important responsible building requirement of the 21st century: the creation of a sustainable link between ecology and economics.

  • Improvement of the U-value
  • Creation of new green spaces
  • New habitats for flora and fauna
  • New relaxation areas, and the creation of leisure facilities and retreats
  • Counteracts the consequences of intense urban development
  • Rainwater retention, thus the burden on the sewage system and sewage treatment plants is relieved
  • Absorption of dust and harmful substances
  • Improvement of the urban climate
  • Noise reduction
  • Usable open-air spaces
  • Reduces the effects of intense paving, surface sealing and increasing building development
