​​DuPont™ Tyvek®  Metal is breathable,  self

supporting, 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 compatible with roof pitches greater than 3º. 

Features and Benefits: 

  • Made in Germany & Backed by DuPont, a 212 year old company
  • Suitable under standing seam, broad pan, metal roof type constructions or any application where extra ventilation is required
  • 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
  • White underside provides for light diffusion properties making DuPont™ Tyvek Metal ideal for warehouse applications
