The DuO Shrink Sleeve is a professional and innovative accessory to make flat roof penetrations watertight.
The DuO Shrink Sleeve combines a sleeve, a flange and a base. The base is made of high-quality, weather-resistant PVC. The shrink sleeve is made of UV resistant Polyolefin. It shrinks when heated by hot air or flame and forms a closed, watertight sleeve around the round object that penetrates your flat roof. It has a special flange of elastomer SBS-modified bitumen for an optimal connection to all DuO membrane systems. The flange diameter is 480mm
