The De Boer shrink sleeve is a professional and innovative accessory to make flat roof
The De Boer 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 UVresistant 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 De Boer membrane
systems. The flange diameter is 480mm
