DuPont™ Tyvek®  Metal is a "CodeMark™  Certified" breathable,  wall underlay that features an integrated drainage mat. The drainage mat provides a separation layer between the cladding and the underlay. This helps manage moisture/condensation in the wall assembly by allowing moisture to drain out of the wall and aids drying. The polypropylene mat can also help reduce mortar damming behind brick cladding. DuPont™ Tyvek® Metal is weather resistant and  comes with a built in adhesive strip to facilitate sealing at overlaps.

DuPont™ Tyvek® Metal is absorbent and may be used behind direct fixed non absorbent wall claddings. Other compatible claddings, including:

  • Metal
  • Fiber Cement
  • Brick
  • Timber/Cedar
  • Stucco/Plaster
  • Asphalt Shingle

DuPont™ Tyvek®  Metal  is available in roll size: 1500mm x 25m (37.5m²)

  • Excellent air and water resistance and not susceptible to abrasion or delamination during the production process
  • Can be installed in all wind zones (including extra high)
  • Helps reduce rain clatter & sound transmission
  • UV resistant for up to 120 days giving the installer more time to install roof
  • 1500mm wide roll covers more area per roll with less overlaps
