Integrated Water-Resistive Barriers or Housewrap?

Filed in Sponsored Content by on March 8, 2019 4 Comments

The abundance of building product choices available today can make it more difficult and time-consuming to choose the right system components for upcoming projects. Simply being “built to code” is becoming a thing of the past with higher-quality products making a big impact in traditional spaces.

Additionally, greater emphasis is being placed on creating more efficient, more resilient and healthier environments by architects, builders and code regulators alike.

It Starts with the Envelope

When it comes to durability, efficiency and resiliency, ZIP System® building enclosures has transformed wood-framed building envelopes with its integrated sheathing. Created as an alternative to wood sheathing with housewrap, ZIP System® sheathing and tape strikes the balance between efficient installation and long-term water and air management. A Structural 1 rated engineered wood panel with an integrated water-resistive barrier (WRB), the system eliminates the need to install an additional weather barrier. Completed with ZIP System™ sealing solutions for panel seams and flashing details, the system delivers a continuous water and rigid air barrier. Code-compliant as an air and water barrier for roof and wall assemblies, as documented in ESR-1473, the system is also backed by a 180-day exposure guarantee and 30-year limited warranty.

Superior Moisture Management

A home’s first line of defense against moisture is its exterior cladding, but should that fail over time, the secondary line of moisture management must guard against water intrusion. The unique textured surface of ZIP System® sheathing panels is engineered to promote the drainage of bulk water. Under third-party testing conducted by Architectural Testing Inc., ZIP System sheathing and tape achieved greater than 90% drainage, while the leading branded housewrap achieved less than 10% drainage.

Housewrap can rip or tear under common jobsite conditions, but the WRB is permanently fused with ZIP System sheathing panels, providing virtually no risk of rips or tears and ensuring the panel’s wood structure is not exposed to damage or detrimental weather conditions.

Tighter Air Barriers

According to the Department of Energy, air leakage accounts for 25-40% of the energy used for heating and cooling in a typical home. Using ASTM E2357, third-party testing by Home Innovation Labs confirmed that ZIP System sheathing and tape provides a tighter air barrier assembly than traditional housewrap. As an integrated sheathing system, ZIP System sheathing and tape creates a durable, rigid air barrier to protect against both air infiltration and exfiltration to help achieve a tight building envelope.

The Answer is Clear

Builders can rest assured in their choice with ZIP System building enclosures, as the system also comes backed by a 30-year system limited warranty from Huber Engineered Woods — protection that is three times longer than that of the leading housewrap warranties. ZIP System® products offer a range of structural panels and sealing solutions to meet residential design and climate zone requirements. While there is no shortage of product choices, high-quality integrated systems should be considered for controlling water intrusion and air leakage and reducing installation steps, which can reduce room for error.

    This sounds like a commercial. What about being able to “breath”? I have read that air must be able to get out through the barrier as well. Is that correct?

  2. Great question! Building tight enclosures allows the builder to control how air enters and exits the home. The home still “breathes”, but where and how the home breathes in a tighter home is determined by the builder.

    What ASTM test was run to get those drainage results? Also, note that DuPont Tyvek(r) DrainWrap(tm) and StuccoWrap(r) test at over 99.93% efficiency per ASTM 2273. Where does the 10% number come from?
