Vegetation carrier for economic and durable extensive green roofs

Available in two different thicknesses, the solution is a durable vegetation carrier. It consists of two components: a lightweight, flexible and very open three-dimensional matting made of entangled polyamide filaments on the top surface. And a nonwoven filter fabric underneath. Both components are firmly connected by means of thermal bonding. One edge of the vegetation carrier is equipped with a filter overlap, which allows adjacent rolls to be joined without any gaps.

The Enka vegetation carrier is delivered in easy-to-handle 3.2 feet or 1 m wide rolls. The portfolio also encompasses a product variant including a water retention fleece on the underside.

In an increasing number of countries and regions, local farmers grow pre-vegetated sedum mats with healthy, mature plants suitable for local conditions. With Enka vegetation carriers this process is highly efficient and requires few resources. The mats can even be produced on lands which are not fertile enough for other crops. Enka vegetation carriers are rolled out and then the layer of entangled filaments is filled with growth substrate. The filaments provide excellent root anchorage to hold the soil in place. A significant advantage for growers: on Enka vegetation carriers the amount of growing medium is just a fraction of that used on trays.

Cuttings from mature sedum mats can be used to start new mats. Harvesting is very simple. No specialized tools or equipment are needed. The cultivated mats are rolled up and then loaded onto a vehicle for transport. Once on site, the rolled blankets of mature plants are easy to lift and place on the prepared roof. They are rolled out like sod on the ground. The blankets are easy to cut with a knife or electrical tool to create shapes and patterns as needed.

Enka vegetation carriers are synthetic and therefore dimensionally stable. They are durable and retain their shape during cultivation. Thanks to its low weight, the finished product can be installed on new-build, and on retrofits or older buildings, either of which may be unable to take heavy additional loads. So existing buildings can be converted easily, installing an environmentally friendly roof without extensive engineering or construction modifications.
