DuPont™ Tyvek® StuccoWrap™

Grooved Housewrap Engineered for Stucco Facades and EIFS Systems

<br><b>DuPont™ Tyvek® StuccoWrap®</b> is a high-performance water-resistive and air barrier (WRB) with an engineered, grooved surface designed to function as a drainage plane behind stucco facades and EIFS systems. It is optimal for both traditional and synthetic stucco systems in commercial and residential construction, effectively reducing cracking, improving stucco curing, and channeling moisture out of the wall. <br><br> Highly inert, <b>Tyvek® StuccoWrap®</b> prevents chemical reactions or degradation when in contact with stucco. It surpasses Grade D paper in managing hydration and maintaining stability during curing, significantly reducing cracking in the scratch coat and enhancing stucco integrity. Suitable for traditional stucco, direct-applied stone masonry, and lapped cedar and cement siding applications up to four stories, <b>Tyvek® StuccoWrap®</b> boasts a proven track record and meets all major building codes by ICC-ES evaluation reports.
 
 
 
 
 
 

Features & Benefits 

 
 
 

default-features-benifits.png
High Performance Durability
  • 30% more flexural strength than stucco cured on 60-minute building paper and 3X stronger tear strength.
  • Sturdy, easy to repair with tape, and not a food source for mold and mildew.
  • Retains durability when wet, channels water to the outside.
default-features-benifits.png
Temperature and UV Resistance
  • Withstands up to four months (120 days) of UV exposure.
  • Maximum in-service temperature of 180° F.
default-features-benifits.png
Air and Water Barrier Performance
  • Does not absorb water, maintaining the moisture level needed for better curing and preventing expansion and contraction, resulting in stronger stucco.
  • Provides superior water drainage, combats moisture accumulation, and prevents air infiltration and exfiltration, thereby protecting the installed R-value of insulation for more comfortable, energy-efficient homes and buildings.
  • Type 1 air barrier, evaluated in accordance with ASTM E1677.
  • Outstanding air infiltration protection and high vapor permeability to promote drying. Offers >98% drainage efficiency when tested in accordance with ASTM E2273.

FAQ

Can DuPont™ Tyvek® StuccoWrap® be used under brick?
Yes. It is perfectly acceptable to use DuPont™ Tyvek® StuccoWrap® under brick. It is also acceptable to use Tyvek® HomeWrap® and Tyvek® CommercialWrap® in this application. When using Tyvek® WRBs under brick, it is important to follow the brick manufacturer’s guidelines regarding the use of an air space between the brick veneer and sheathing. Typically, this space is 1-2 inches, and will act as a drainage plane if incidental moisture penetrates the brick, in addition to ventilating behind the cladding, which aids in drying of the wall assembly.
