Tyvek Metalized Tape by DuPont
What It Is
Tyvek Metalized Tape is a metalized polyester film tape with a strong adhesive backing. The “metalized” surface is not actual metal foil but a polymer film with a reflective metallic coating that increases strength and weather resistance compared with standard paper tapes.
Key Uses
This type of tape is typically used to:
- Seal seams and joints in Tyvek house wrap or other weather-resistant barriers.
- Flash around penetrations like windows, doors, and vents to help reduce air and moisture infiltration.
- Bridge gaps between building materials to create a continuous water-resistive barrier.
- Reinforce corners and transitions, especially in areas exposed to weather or wind driven rain.
Performance Characteristics
- Durable & weather-resistant: The metalized film resists tearing, UV degradation, and moisture better than many cloth or paper tapes.
- Strong adhesive: Bonds well to Tyvek and many common building materials (like wood, metal, and housewrap).
- Reflective surface: Helps with durability and sometimes improves visibility during installation.
- Good for exterior use: Suitable for above-grade applications and exposed areas when properly installed.
