The SMARTci building enclosure system is recognized for its ability to enhance structural performance and energy efficiency in construction. This innovative system installs in a single pass and achieves 92–99% thermal efficiency, eliminating thermal bypass. It also provides the highest R-value available, offering up to 50% higher performance than competitive systems. Understanding the installation methods for SMARTci on both open and closed framing is essential for achieving optimal results. This article delves into the specific installation processes for each method, highlighting their distinct characteristics.
Framing Types
Closed Framing
Closed framing involves enclosing the framing members with sheathing, which can improve structural integrity and thermal performance. This method is typically preferred in regions with strict building codes that emphasize energy efficiency and moisture control. It’s important to note that sheathing and a weather-resistive barrier (WRB) are required on closed framing.
Open Framing
Open framing is a construction method where the framing members are exposed, providing flexibility in design and often allowing for easier installation. This approach can lead to significant material savings by potentially eliminating the need for sheathing and a WRB. Additionally, the simplified installation process reduces labor costs, making it a cost-effective choice for many projects.
Closed Framing Installation Process
The installation of the SMARTci building enclosure system for closed framing begins with thorough substrate preparation, which is essential for ensuring a successful outcome. It is critical to ensure that the substrate is dry, clean, sound, and free from any debris or contaminants. This preparation phase lays the groundwork for effective adhesion and sealing. Before installation, sheathing and a WRB must be installed behind the SMARTci system. This barrier serves as a vital layer of protection against moisture intrusion, which is particularly important for maintaining the integrity of the building envelope.
Once preparation is complete, installation commences at a transition or termination point, working horizontally from the bottom up. Proper sizing of the bottom custom-profiled starter polyiso insulation panel is crucial for achieving a seamless fit. After securing the starter panel, the next step is to attach the GreenGirt CMH Z-girt to the substrate using approved low-profile fasteners.
With SMARTci, all polyiso panels arrive at the job site custom-profiled to the exact specifications of the GreenGirt CMH Z-girt and are cut to the dimensions needed for your building with tolerances not to exceed 0.005 inches. Since Advanced Architectural Products precision cuts all insulation before shipping it to your job site, your crew can focus on the tasks you hired them for rather than cutting or routing insulation. Install each row of polyiso panels on top of interlocking GreenGirt CMH Z-girts, then top it with another row of interlocking GreenGirt CMH Z-girts – essentially creating a stack-and-go system that installs four times faster than other systems. For installations over closed framing, the SMARTci system achieves a water-tightness to 1.57 PSF and an air-tightness to 6 PSF.
Open Framing Installation Process
Similar to closed framing, open framing installation also starts at a transition or termination point, working horizontally from the bottom up. Proper sizing of the bottom custom-profiled starter polyiso insulation panel remains critical for a seamless fit. The starter GreenGirt CMH ZZ-girt is then pressed into the channel, with gentle tamping to ensure a tight fit. This method emphasizes the importance of accuracy in maintaining the system’s integrity and performance.
Secure the starter panel, then attach the GreenGirt CMH Z-girt to the substrate using approved low-profile fasteners. The installation of insulation panels follows, starting with the first row of custom-profiled panels placed above the starter row. In addition, spray foam is also used at termination points.
There are two options for installing SMARTci on open framing: one that includes a WRB installed outboard of the SMARTci system and the other that incorporates a bead of caulk at each corner of the insulation, along with taping over all vertical joints:
- With a WRB: Once the stack-and-go SMARTci system is fully installed over open framing, a WRB (by others) is applied outboard of the system to enhance air- and water-tightness.
- With Caulk and Tape: In open framing, an approved sealant is applied at all four corners as each panel is installed to ensure a robust seal. Like the closed framing installation, each row of polyiso panels is placed on top of interlocking GreenGirt CMH Z-girts in a stack-and-go sequence, with caulk applied at each corner. Tape is then added to each vertical joint to maximize air- and water-tightness. This method allows for the potential elimination of sheathing and the WRB, using caulk and tape to increase air- and water-tightness to 20 PSF.
Considerations and System Advantages
The SMARTci system stands out for its innovative approach to insulation and energy efficiency. One notable advantage is its ability to streamline the construction process. The single-pass installation not only reduces labor time but also minimizes the potential for errors associated with multiple-step installations.
In addition to its thermal efficiency, the system’s design allows for enhanced flexibility in building design. It can accommodate a variety of cladding options, making it suitable for diverse architectural styles. This adaptability can be particularly beneficial in projects with unique aesthetic requirements.
The open frame installation method offers several distinct advantages that make the SMARTci system an appealing choice for builders. First, it typically requires fewer materials, which can significantly reduce material costs. This method allows for the potential elimination of sheathing and a WRB by utilizing caulk and tape, further streamlining the installation. Additionally, the open framing process often results in reduced labor requirements, as the simplified steps allow for assembly in a single pass and easier access during installation. These benefits not only contribute to overall project efficiency but also accelerate the schedule. They also enhance the long-term viability of the structure.
It is crucial to ensure thorough training for installation teams. While the installation process streamlines, understanding the nuances of the SMARTci system and its components is essential for maximizing performance. Additionally, considering local climate conditions during planning can enhance the system’s effectiveness and contribute to optimal energy savings.
Overall, while the SMARTci system offers numerous benefits, proper installation, and thoughtful planning are key to unlocking its full potential.
Conclusion
The installation methods for the SMARTci building enclosure system on open and closed framing each have distinct characteristics. These methods cater to specific building requirements. Understanding these nuances is essential for ensuring a successful installation that optimizes the system’s performance and longevity. Encourage builders and architects to follow best practices and consult technical guides to achieve the best results in their projects.
For those seeking to enhance their building’s energy efficiency and structural integrity, exploring the SMARTci building enclosure system is a valuable step forward. Discover the innovative SMARTci building enclosure system and revolutionize your construction projects.
