High-performance, base pitched roof membranes with premium longevity!

We optimise our products continuously, which enables us to achieve consistently optimal results. We have now embarked on a new mission! The goal: the next generation of roofing membranes with impressive longevity – even under the toughest conditions. To allow us to also offer this characteristic in the standard segment, we have thought this through further and now present our new DELTA-XX PLUS® family: reliable, longlasting, German-made and with a 30-year functional warranty.

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.
