A. Proctor Group Wraptite® UV is a premium, self-adhering, airtight, and highly vapour-permeable breather membrane explicitly designed for use behind open-jointed cladding systems. This commercial-grade membrane features advanced UV and water resistance (Class W1), delivering long-term weather protection while providing a seamless, dark "shadow" appearance within open rainscreen façades.
By fully bonding to multiple building substrates without requiring a primer, mechanical fixings, or additional tapes, Wraptite® UV eliminates lateral air movement, drastically improving building thermal performance and energy efficiency.
Key Features
- Superior Airtightness & Breathability: Provides extreme airtightness (<0.01 m³/(m²⋅h⋅50Pa)) balanced with a high vapour permeability rating of Sd 0.06m to prevent moisture buildup and structural rot.
- Class B Fire Rating: Independently tested to achieve a Class B-s2, d0 reaction to fire classification over calcium silicate board.
- Primerless Self-Adhesive Design: Formulated with a proprietary acrylic moisture-vapour permeable adhesive that bonds securely to concrete, steel, timber, plywood, OSB, rigid vinyl, and aluminium.
- Robust Construction & Durability: Manufactured from a tough polyester facer laminate with a functional coating that resists punctures and tears during installation.
- Extended Exposure Rating: Safely remains uncovered and exposed to UV elements for up to 12 months in Central European climates prior to final cladding installation.
- Temperature Resilience: Engineered with a wide installation temperature range of -10°C to +60°C and a service temperature range of -40°C to +100°C.
Applications
- Ventilated rainscreen systems and open-jointed timber or metal cladding.
- Shadow gap detailing behind window flashings.
- High-rise façade construction, volumetric module manufacturing, and offsite panelised modular building systems.
Optimised Installation & System Integrity
For complex detailing, window/door openings, and wall penetrations, maintain a continuous airtight seal by pairing the membrane with official accessories from Proctor Group
- Wraptite Liquid Flashing (LF): A gunable, elastomeric polyether liquid membrane perfect for pre-filling gaps and sealing raw substrate edges.
- Wraptite UV Tape & Split Liner Tape: Crucial for achieving the required minimum 75mm overlaps, patching minor punctures, and completing fast, "shingled" structural connections.
- Proctor Wraptite UV Breather Membrane is 1.5m wide, 50m long, covers 75 sqm.
- Wraptite UV is a Class B-s2,d0* membrane that combines the optimum properties of vapour permeability and air tightness in one self-adhering product
- Wraptite UV bonds (no mechanical attachment) to multiple substrates for air tightness and ease of installation
- Specifically designed for use behind open jointed cladding.
