Reinforced octagonal structure
This membrane is particularly suitable for protection and drainage in rooftop gardens, even in contexts with water storage needs. When used as a protection and drainage layer for inverted roofs, it stands out for its octagonal reliefs, which guarantee high compression resistance. Its microperforations facilitate drainage and vapor diffusion from the underlying layers.
Product details:
Versatile, suitable for both inverted roofs with extensive green coverings and roofs with gravel or interlocking stone coverings.
High drainage capacity, ideal for green roofs. The microperforations make the membrane vapor-permeable, with an S d value of approximately 0.4 m, optimizing its application in inverted roofs. In drought conditions, the membrane can provide a water reserve of up to 7 l/m^2. The new 20 mm octagonal reliefs increase compression resistance up to 200 kN/m^2, ensuring optimal water storage as well.
Easy and fast application, thanks to the roll format that covers an area of 40 m^2. Additionally, the membrane is rot-proof and does not alter the quality of drinking water.
In compliance with EN 13252 standard, DELTA®-FLORAXX is CE marked.
