The combination of layers with varying performance makes the breathable soft sheating and sarking sheet particularly robust – over the course of many years. Because its proven longevity ensures a lastingly secure roof. Its great robustness means it offers optimal protection during installation.
The extremely resistant roofing membrane is tailored perfectly for use on roofs with formwork. Naturally, it is also suitable for use on fully insulated roofs without formwork.
New from 01/01/2023
DELTA-XX PLUS® HEAVY is the robust solution for roofs with formwork and meets the requirements of ZVDH product data sheets UDB-A and USB-A. The roofing membrane can also be used as temporary roofing for the provisional protection of a roof. In addition, it is also suitable for use as base layer under metal roof coverings, fibre cement panels or slate and as façade membrane behind ventilated cladding with closed joints.
