    The next generation of roofing membranes – with impressive longevity

    “The roofing membrane is the weak spot of the roof.” This feedback from experienced roofers was the challenge that we faced. We therefore embarked on a new DÖRKEN mission. Our goal: to develop roofing membranes with very high longevity and greater resistance under even the hardest conditions. The continuous optimisation of our DELTA® products is in our DNA and is key to our success – as proved the case again this time. We have redefined longevity and made our proven roofing membranes even better – German-made, naturally.

    30 year guarantee for lasting security

    The primary outcome of our mission: the next generation of roofing membranes with a 30-year warranty (New from 01.01.2023). The findings from our successful journey have been incorporated into our DELTA®-MAXX PLUS and DELTA®-FOXX PLUS premium products and our new products of the DELTA-XX PLUS® family, on which we give you a 30-year functional warranty - our promise for your safety!

    You receive the warranty according to our warranty statement. The statement you can find here.

    This is made possible through the combination of proven raw materials, our in-depth knowledge of these and the use of state-of-the-art production technology, such as the DELTA®-BiCo- and DELTA®-AdTec technology. Extreme quality testing and long-term testing, also taking account of air movement as key ageing factor, as well as special test procedures confirm the particular resistance of the new generation.
    Our innovation has been explicitly substantiated by the ETA. This package allows us to radically slow the ageing process for our roofing membranes. As a result, our premium products are suitable for any application – whether it is the conversion of an old roof, the building of a new one or renovation work.
