Powerlon UV 120 - UV Facade Membrane - 1.5M x 50M

Powerlon UV 120 is a high-performance UV resistant facade membrane designed to protect open-jointed cladding systems and enhance the durability of the building envelope. Supplied in a convenient 1.5m x 50m roll, this black facade membrane is ideal for contemporary architectural designs where aesthetics and performance go hand-in-hand.

Crafted to meet the demands of ventilated façades, the Powerlon UV 120 Black facade membrane allows the structure to breathe while offering robust protection from wind, rain, and UV degradation. Its breathable design helps to ventilate behind external cladding, reducing the risk of trapped moisture and mould, especially in timber-based constructions.

Key Features:

• Exceptional UV resistance – ideal for use behind partially open cladding and rainscreen façade systems (Max gap 30mm)
• Breathable and water-repellent to support ventilation while protecting the building envelope.
• W1-rated for water tightness, ensuring maximum weather resistance.
• Plain black, unprinted, and unbranded for a clean, discreet appearance behind façades.
• Compatible with all substrates, including timber and masonry.
• CE approved to meet rigorous European standards for construction materials.

Installation Guidelines for Powerlon UV 120

To ensure optimal performance of the Powerlon UV 120 breather membrane, follow these installation best practices:

• Membrane Handling: Avoid creasing or folding the membrane during installation. For corners, either loosely wrap the membrane or create a well-sealed butt joint—never sharply crease the material.

• Orientation: Unroll the membrane so that the inner side of the roll faces outward once installed.

• Fixing: Pull the membrane tight to eliminate slack. Secure all loose ends, overlaps, and edges using mechanical fixings such as staples, or seal with Powerlon® UV Facade Sealant or Powerlon® UV Facade Tape.

• Adhesion: Do not bond the membrane to non-rigid surfaces like insulation.

• Staple Sealing: If staples are used, ensure they are sealed with Powerlon® UV Facade Tape or Powerbond® Butyl Tape.
