Performance Features

Chemical self-bonding: Wakaflex chemically bonds to itself with a minimal overlap of just 30–50 mm, eliminating the need for mastics or heat welding and ensuring a long-lasting, watertight seal.
High flexibility: Offers 50% stretch along its length and 15% in width, allowing it to mould precisely to complex roof profiles and shapes.
Thermal and UV resistance: Tested for temperatures from -40 °C to +100 °C and compliant with UV stability standards.
Water-safe and non-toxic: Certified under AS/NZS 4020 as safe for use in contact with potable water and tested to AS/NZS 2904 standards.
BAL-29 compliance: Suitable for use in areas rated up to BAL-29 for bushfire risk.
Quick and easy installation: Requires no specialist tools—only a knife or scissors—reducing installation time by up to 50% compared to lead alternatives.
Covered by a 10-year manufacturer’s warranty across Australia and New Zealand.

Typical Uses

Wakaflex is ideal for use in step and cover flashings, chimney and dormer flashings, apron flashings, roof valleys, and where two different roofing materials meet. It is particularly suited to new construction projects as well as repairs and retrofits. The aluminium-reinforced sheet ensures shape retention, while the integrated butyl strips provide an immediate seal to metal, tile, concrete, or other roofing substrates.
