For Tough to Ventilate Roofs...
DuPont™ Tyvek® Metal is a "CodeMark™ Certified" breathable, self supporting, roof underlay consisting of DuPont™ Supro Synthetic Roof Underlay with an integrated drainage mat. The drainage mat provides a separation layer between the roof cladding and the underlay. This helps condensation drain out of the roof and aids drying of the roof assembly. DuPont™ Tyvek® Metal is self supporting (spans up to 1200mm), 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 claddings.
