Successful buildings must have a solid foundation to withstand structural load demands, which includes having a durable building envelope and cladding support system. The GreenGirt CMH™ continuous insulation and SMARTci® building enclosure systems are designed to provide strength and long-term durability for any cladding requirements. While these systems are capable of handling structural loads of any cladding material, two accessories are available from Advanced Architectural Products for projects with unique cladding or extreme performance requirements: (1) GreenGirt CMH™ Double Z-girts and (2) GreenGirt CMH™ Dead Load Clips. These optional accessories are available to increase structural support and durability in case additional support is needed for projects with unique cladding or extreme spacing. This article highlights these accessories and the support they can provide to GreenGirt CMH and SMARTci systems, and projects that have used them to support unique cladding requirements.

Double Z-Girts

GreenGirt CMH Double Z-girts are a powerhouse of structural innovation—two GreenGirt CMH Z-girts fused with a quarter-inch aluminum insert to form an unstoppable structural hat. Engineered for the most demanding applications, they mount horizontally or vertically to walls as a fortress of support. Built to handle extreme spacing challenges and the weight of unconventional cladding materials, these next-level accessories can shoulder over 500-pound point loads with ease. Designed for maximum strength and relentless durability, Double Z-girts push the limits—delivering hardcore performance without compromising an ounce of thermal efficiency.

GreenGirt CMH™ Dead Load Clips

Unleash the power of GreenGirt CMH Dead Load Clips – the ultimate vertical composite metal hybrid accessory engineered to supercharge your structural support. Designed to reinforce deeper horizontal GreenGirt CMH systems under intense stress and deflection, these clips deliver unmatched strength and durability. While our horizontal systems already handle a variety of cladding materials with ease, Dead Load Clips elevate performance, tackling unique cladding challenges head-on. Built for serious load demands, they boast the muscle to carry over 500-pound point loads – comparable to the raw strength of GreenGirt CMH Double Z-girts.

Bryan Medical Center

The Bryan Medical Center East Campus Project in Lincoln, Nebraska, is a section of the Bryan Health Hospital consisting of inpatient and outpatient services, heart services, 24/7 emergency care, and more. Construction for this project used SMARTci on closed framing for the walls, installed horizontally at 3” deep and 16” on center, with zinc reveal and zinc flat rock cladding. GreenGirt CMH Double Z-girts were used for additional support and durability when pairing heavy zinc reveal and zinc flat rock cladding with the SMARTci system.

Stockton Residence Hall

Construction of the Stockton Residence Hall in Atlantic City, New Jersey, with Shildan terra cotta cladding, GreenGirt CMH, and Double Z-girts.

The Stockton Residence Hall in Atlantic City, New Jersey, is a new student-life housing facility for Stockton University. This building houses more than 400 students and promotes unique features, such as ocean-front views. This building used GreenGirt CMH on the walls, installed horizontally at 4” and 3.5” deep and 24” on center. Because this residence hall used Shildan terra cotta cladding, GreenGirt CMH Double Z-girts increased the building’s durability and structural integrity, while also enhancing thermal efficiency for this unique cladding project.

The Living Building at Georgia Tech

The Living Building at Georgia Tech in Atlanta, Georgia, is 28th in the world to receive the Living Building Challenge certification through its net-positive energy and water every year, giving back to the environment more than what it takes in. This LEED Platinum-certified project used GreenGirt CMH on the walls, installed horizontally at 3” deep and 16” on center, with steel fin cladding. GreenGirt CMH Double Z-girts at 3” deep supported the GreenGirt CMH system with this uniquely heavy cladding for guaranteed durability and structural capacity, without sacrificing thermal efficiency.

Conclusion

Take your building’s performance to the next level with GreenGirt CMH Double Z-Girts and GreenGirt CMH Dead Load Clips! These powerful accessories supercharge structural integrity, especially for projects with unique cladding demands. While GreenGirt CMH systems are built to handle any cladding with ease, these add-ons deliver extra strength and durability without compromising thermal efficiency.
