DELTA-MAXX®

In addition to DELTA-MAXX® X, DELTA-MAXX® PLUS energy-saving membrane and DELTA-MAXX® WD, DELTA-MAXX® is the only underlay to have a moisture storage surface. 

®

The "damp storage surface" on the underside reliably absorbs the moisture even in extreme situations and gradually releases it to the outside later. With the Sd value of approx. 0.15 m, the safe removal of moisture is guaranteed.

The high tear resistance offers maximum safety when laddering on the roof battens. The high strength in the longitudinal and transverse directions enables fast and precise unwinding.

Quick to install thanks to the smoothed fleece underside. 

Facilitates installation work due to the checkered surface embossing: straight cut edge when cutting.
