DELTA-XX PLUS® HEAVY: Breathable Membrane for Boarded Roofs
DELTA-XX PLUS® HEAVY is a vapour-permeable roofing underlay for pitched roofs. Laid over rafters or sarking boards, it protects the roof and insulation from wind-driven rain, snow and dust, while letting moisture from inside the building escape.

Advantages
- Long-term functionality
Built for longevity and keeps its performance for years, backed by extensive quality and long-term testing and a corresponding ETA.
- 30-year warranty
If a guaranteed property fails despite expert installation, Dörken replaces the material and covers removal and reinstallation costs.
- Practical self-adhesive strips
An integrated self-adhesive edge strip bonds the overlaps quickly and securely, keeping cold air and moisture out of the insulation.
- Highly breathable
A permeable functional layer between spunbond fabrics lets building moisture and condensation dry out quickly. Breathability is well above bitumen-based membranes and many plastic sheets.
- Optimised for roofs with boarding
Heavy, thick fabrics protect the functional film from rough surfaces during installation.
- Technology
Equipped with DELTA®-AMS, DELTA®-BiCo and DELTA®-AdTec technologies.
Where to Use
A robust solution for roofs with boarding (formwork). Meets ZVDH product data sheets UDB-A and USB-A. Can serve as temporary roofing, as a base layer under metal roof coverings, fibre cement panels or slate, and as a façade membrane behind ventilated cladding with closed joints.
