Modern Green Roof Build-Up

The Technical Role of Nonwoven Substrates

Modern green roof systems rely on interconnected functional layers that operate as an integrated unit to ensure long-term durability and hydraulic performance. Within these assemblies, specialized technical nonwovens play a vital role by providing soil retention, unhindered drainage, and mechanical protection for underlying waterproofing membranes.

An example solution for extensive green roofs with a slope of up to 5 degrees, ideal for structures not designed to withstand heavy loads.

Lama technical nonwovens feature high tensile strength, exceptional tear resistance, high water permeability, and superior resistance to biological degradation and UV exposure. They are specifically optimized for integration with dimpled drainage sheets as well as the manufacturing of compact modular panels used in vertical living wall installations.
