DuPont™ Tyvek® Fluid Applied WB+™ System
DuPont™ Tyvek® Fluid Applied WB+™ System, the next generation of fluid applied air/water barriers in the portfolio of DuPont Building Envelope products takes the industry-leading performance of traditional DuPont™ Tyvek® Fluid Applied products and combines superior air and water barrier and industry-leading vapor permeability, into a reformulated fluid-applied membrane for ease of use on most commercial substrates. 

Features
​Single component, one-coat application that is low VOC and exhibits extremely low shrinkage during curing, reducing the amount of product needed to complete installation.  It is part of a complete, integrated fluid applied weather barrier system, all backed by a limited 10-year warranty from DuPont.

​
Applied in one-coat application by spraying or pressure rolling, DuPont™ Tyvek® Fluid Applied WB+ delivers superior protection, excellent durability and saves time by providing two to three times the coverage of competitive products per gallon. The product can be sprayed or pressure-rolled on a broad range of substrates. The system is engineered to withstand nine months of UV exposure, which allows for a more flexible construction scheduled. Contributing to this flexibility, the system can be applied on damp walls, and at a wide range of temperatures--as low as 25°F ambient to 140°F surface.
