The main layer of the product is a three-layer superdiffusion membrane that withstands a column of water with a height of 280 CM and steadily maintains water permeability before and after the aging test.
As a draining element of the membrane, a special polypropylene layer is used in the form of intertwined fibers with a height of 8 mm. This layer is designed to protect the inside of the metal roof from getting wet.
The drainage layer collects the drops of condensation, diverts them to the superdifusion membrane and thus keeps the inner surface of the folded roof dry and long-lasting.
Thanks to the drainage layer installed in contact with a folded coating, the membrane significantly improves the comfort of the ceiling with a metal roof, reducing rain noise.
