PlenaTex 110-135-150-180-225

DESCRIPTION
PlenaTex is a range of multilayer synthetic waterproof and breathable membranes, made of two layers of nonwoven polypropylene fabric and a central functional polypropylene film, bonded using ultrasonic welding. This manufacturing process ensures strong cohesion between layers while delivering structural consistency, dimensional stability, mechanical resistance, and long-term durability.
All PlenaTex models are rated W1 according to EN 13859-1, ensuring maximum water resistance.
PlenaTex 110 offers an excellent balance of breathability and strength, while models 135, 150, 180, and 225 are designed for more demanding applications thanks to their enhanced mechanical robustness and a UV-resistant, anti-slip, and abrasion-resistant surface finish—features that improve both safety during installation and long-term performance in harsh conditions.
PlenaTex 150 complies with the ZVDH guidelines (Central Association of German Roofers), classified as UDB-A, ensuring high performance for roofing applications as required by the German market.

APPLICATION
The PlenaTex range is designed for use as a waterproof and breathable membrane installed above the insulation layer, with specific applications for both exterior walls and pitched roofs.
PlenaTex 110 is especially suitable for vertical exterior walls, installed over the insulation and behind the facade cladding. In this context, it helps maintain the proper moisture balance in the wall assembly, prevents interstitial condensation, and contributes to preserving the thermal performance of the insulation over time.
PlenaTex 135, 150, 180, and 225 are intended for discontinuous pitched roofs, particularly ventilated roofs with insulation made of mineral wool, PIR, EPS, or wood fiber. In these cases, the membranes allow vapor to escape from inside to outside, ensuring moisture control of the roof assembly and providing added protection against accidental water infiltration.
The entire PlenaTex range helps maintain the building envelope’s energy performance and durability, effectively meeting today’s construction needs for efficiency, reliability, and safety.
