For many years now, green roofs are well accepted as a visually attractive and cost-effective method of roof construction, and are becoming increasingly used on account of their advantages in terms of aesthetics, ecology and physical characteristics. Due to their added value related to energy efficiency, the improvement of the microclimate and cutting the peaks of rainstorm runoffs, many city authorities and councils are more and more promoting the use of green roofs.

Green roofs can give architects and building engineers more scope for aesthetic design and environmental improvement by reducing the number of hard surfaces in built–up areas.

Green roofs retain anything up to 50% of precipitation, spreading the runoff over much longer periods of time. As a result, green roofs can reduce the need for expensive drainage extension works, this helps to the civil engineer cut back construction costs significantly.

With Enkadrain, Colbond offers a multifunctional layer for the drainage of surplus water, protection and filtration without the risk of clogging. The nonwoven filter layer serves both to protect the sealing layer and as a separator from the substrate. The choice of the right Enkadrain product type depends on the specific roof structure and use. The Enkadrain product range covers a large number of different drainage mats, each designed for a specific purpose. Certain types of Enkadrain are designed for use in extensive or intensive green roofs; others offer effective solutions for construction projects where roof gardens are intended to take vehicular traffic or other heavy loads, making compression resistance essential.
