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.
