The Steico multi UDB membrane is a high-performance, three-layer solution for creating airtight and weatherproof roof structures. It supports both new construction and renovation projects with excellent flexibility. This membrane ensures a reliable barrier against wind and driving rain while allowing water vapor to escape effectively.
Thanks to its sd-value of just 0.02 m, it offers outstanding breathability. At the same time, its three-layer design makes it extremely tear-resistant. The dual integrated self-adhesive strips make installation quick and secure—no additional sealing is needed at overlaps.
You can use the Steico multi UDB on roofs with a slope greater than 10°, depending on the roof type. Moreover, it withstands temperatures between -40 °C and +80 °C, which means it’s suitable for a wide range of climates. Another key advantage is its resistance to weather exposure for up to 3 months. This feature offers added flexibility, especially on renovation sites.
