OLDROYD® Xv 20 Sedum is a perforated drainage membrane for sedum roofs manufactured in anthracite gray polypropylene (PP).
The membrane has 20 mm high studs that create excellent drainage and water reservoir for about 4 liters per m2. The approximately 10 mm holes in the membrane allow excess water to drain.
OLDROYD® patented crisscross pattern ensures adequate cross ventilation between geotextile and the membrane, which is beneficial for the sedum. The membrane works well in areas with varied rainfall.
