COMMERCIAL WATERPROOFING MEMBRANES
If we promise that a DuO roofs will last for decades, then we aim to make that promise come true. That is why DuO roofs are tested by independent bodies (WTCB in collaboration with SGS and specialized labs) for its sustainability. The first DuO sustainability report dates from 2000, 10 years after the first DuO roofs made their appearance. A second sustainability report followed in 2005, which again yielded good results. At the third sustainability report in 2010, it was concluded that DuO, with proper maintenance, has a lifespan of at least 35 years.
In the course of 2015, a fourth sustainability study will be conducted worldwide.
A remarkable fact is that the results of the first three sustainability studies in all continents and climatic conditions reach the same high level.
