10-Year DuPont™ Tyvek® and AirGuard® Limited Warranty

Uniquely developed to provide years of long-lasting protection, DuPont building envelope system products are covered by a 10-year Tyvek® and AirGuard® Limited Warranty.

Tyvek® breather membranes and AirGuard® air & vapour control layers (AVCLs) are designed to offer high quality, long-term protection while also helping to improve your building’s thermal efficiency.

DuPont has long-standing reputation and experience, which means that you are not just installing a great insulation solution, you are installing peace of mind too.

The DuPont 10-year warranty covers damage or failure of Tyvek® membranes and AirGuard® AVCL products when fitted correctly in all building types and adhering to DuPont installation guidelines, provided DuPont receive written notice of any defects within 30 days of their appearance in the products. Supporting documents indicating the purchase or installation date should accompany any claim made under warranty and a DuPont representative should be allowed to inspect installed products about which a claim has been made.

The 10-year warranty does not cover damage or failure caused by natural events, physical penetration or vandalism or where a design fault in the building structure is the cause of the issue. Similarly, if a DuPont building envelope system product has been incorrectly installed, the 10-year warranty is then void.
