Rainscreen Sheathing Panels
Huber Engineered Woods
The company’s ZIP System product line consists of sheathing panels with integrated WRBs and sealing solutions to achieve an airtight seal. The ZIP System Rainscreen can help builders streamline their approach to water and air management in high-performance wall assemblies. It consists of a rigid drainage mat covered by a heavy-duty fabric that allows it to be used as a secondary water-resistive layer required for “absorptive” or “reservoir” cladding assemblies. Combining the high-compression strength of the mesh drainage mat with the 5 to 7 perm water resistive fabric layer strikes an excellent balance of durability and effective moisture management.

Self-adhered Rainscreen
VaproShield
RainScreen SA is an innovative self-adhered Air Barrier/WRB with an integrated rainscreen drainage matrix, streamlining installation and ensuring moisture control. This solution features a factory-bonded drainage matrix for efficient moisture management. Its robust adhesive facilitates bonding to diverse substrates, while its zero VOC composition enhances environmental safety. A remarkable drying capacity of 25 perms not only improves energy efficiency but also promotes material durability. Per the recent IBC-2021 revisions, RainScreen SA conforms to Section 2510.6’s drainage requirements by providing a 3 millimeter and 7 millimeter integrated drainage matrix, ensuring both compliance and effective moisture management.

Conformable Membrane
Sto Corp.
StoGuard Conformable Membrane, a self-adhered membrane used within StoGuard air and water-resistive barrier systems. The new membrane is used to seal dynamic joints, sheathing joints, substrate transitions, penetrations, and rough openings. The aggressive adhesive does not require priming on most substrates and allows installation at temperatures as low 20 degrees Fahrenheit. The facer membrane provides an incredible 1,470 percent elongation, which helps it conform to complex building shapes. The product has met AAMA 711-13 window flashing and ICC-ES AC212 sheathing joint requirements. It is fully compatible with all StoGuard products.

With this wrap, builders get the industry-leading performance of building wraps with an integrated solution to manage bulk water that gets behind cladding. No other product brings together that capability with the exceptional tear strength, holdout, and breathability building wrap is known for. It is ready to go to work right alongside the manufacturer’s full line-up of high-performance flashings, tapes, and accessories to protect against the elements. For more information, visit typar.com.
Weather Resistive Barrier for CI
Atlas
EnergyShield Continuous Wall Insulation can be used as a three-in-one product, providing exceptional thermal performance, an air barrier, and a WRB, while streamlining the overall wall design. This gives architects, designers and contractors assurance that the products they have selected will deliver high performance and long-lasting protection. Use of it is supported with educational resources and personal customer service advice. The product is approved as a standalone WRB and air barrier by properly sealing the joints and penetrations with an approved self-adhered tape. Through rigorous third-party testing under AC71 (Foam Plastic Sheathing Panels Used as a WRB), Atlas has confirmed the compatibility of approved tape flashing options, which provides the architect and installer more freedom in the adhesive selection, market availability and budget control. It can be used as a WRB in both residential and commercial applications. For more information, visit wall.atlasrwi.com.
High Performance WRB
Benjamin Obdyke
Flatwrap HP is a high performance housewrap designed for use in non-absorptive cladding applications or in conjunction with a rainscreen for other applications. The product offers superior durability via a trilaminate polypropylene substrate. The trilaminate design protects the water hold out layer from damage during install. It can be installed as an air barrier and is also breathable with an ideal perm rating between 10 and 20 perms per building science research. The product can be exposed for 120 days before cladding install and offers a gray, low glare surface for easy install. Available in 3-, 5- and 9-foot sizes, it offers a size option to fit project needs. The product contributes to the 25-year system warranty for the company’s rainscreen products, Slicker MAX and Slicker Classic. For more information, visit BenjaminObdyke.com.
