PlenaWeb

DESCRIPTION
PlenaWeb is a high-performance separation layer for sloped metal roofs. With a total weight of 500 g/m², it consists of a three-layer waterproof and breathable polypropylene membrane, bonded to a high-density polypropylene monofilament 3D mesh.
Its multilayer structure—comprising the 3D mesh, nonwoven fabric, breathable waterproof film, and an additional nonwoven fabric—creates a continuous micro-ventilation chamber between the metal roof and the membrane underneath. The overlap area features an adhesive strip for faster installation and improved adhesion.

APPLICATION
PlenaWeb is designed for use as a separation layer in sloped roofs finished with metal, suitable for both ventilated and non-ventilated configurations.
Its installation creates a micro-ventilated space under the metal sheet, allowing condensation to drain and preventing mold and mildew, thus avoiding degradation of the thermal insulation and maintaining long-term performance.
The 3D mesh also acts as an anti-vibration element, significantly reducing noise caused by rain or hail, thereby improving indoor acoustic comfort.
It is the ideal solution for modern metal roofing systems that require excellent breathability, protection, and living comfort.
