Proper insulation is foundational to energy-efficient, sustainable construction. Yet even minor insulation gaps and cracks can severely degrade thermal performance, causing increased energy costs, diminished indoor comfort, and potential moisture issues.
At Advanced Architectural Products, we offer innovative solutions specifically designed to address these persistent challenges—GreenGirt CMH™ continuous insulation and SMARTci® building enclosure systems, ThermaLock technology, pressure seals, and custom-profiled rigid insulation—ensuring maximum efficiency and long-lasting building performance that eliminates both thermal bypass and thermal bridging.
GreenGirt CMH and SMARTci: Closing the Gaps
GreenGirt CMH and SMARTci systems directly target common insulation pitfalls, particularly thermal bridging, thermal bypass, and installation irregularities. Traditional metal Z-girts create continuous thermal bridges that compromise insulation effectiveness. GreenGirt CMH Z-girts, however, incorporate advanced composite metal hybrid materials that eliminate heat transfer through structural components.
SMARTci systems further enhance this capability by integrating structural support with custom-profiled rigid insulation, resulting in a seamless insulation layer that eliminates thermal bridging. This system ensures an uninterrupted blanket of insulation across the building envelope, providing energy savings and consistent indoor temperatures.
ThermaLock Technology: Enhancing Airtight Performance

Gaps and cracks don’t just reduce thermal performance; they also create pathways for air infiltration, undermining building airtightness with thermal bridging and thermal bypass. According to the PassiveHaus Trust, a mere 10mm air gap behind insulation boards can reduce thermal efficiency by up to 50%. This is common in metal and FRP systems because they lack secure insulation retention technology integrated into the system, leading them to use materials that result in unintended air flow and thermal bypass.
ThermaLock technology on GreenGirt CMH Z-girts and SMARTci specifically targets these vulnerabilities. Utilizing precise engineering, ThermaLock integrates dual three-point compression seals to create an airtight insulation system that eliminates thermal bypass and thermal bridging because the air gap behind the insulation has been eliminated and the air movement between the Z-girt and the insulation has been stopped.
ThermaLock technology forms a secure connection between the Z-girt and the insulation, eliminating air and moisture flow and improving overall thermal efficiency. The combination of airtight sealing and continuous insulation eliminates common sources of energy loss, leading to noticeably improved building performance and occupant comfort that address the concerns of thermal bridging and thermal bypass.
Pressure Seals: Ensure Continuously Connected Panels
Installation of the SMARTci compression pressure seals that connect each rigid insulation panel together for high-quality thermal efficiency.
Compression pressure seals in the SMARTci system are used as butt-joint attachments between adjacent rigid insulation panels to provide additional air- and water-tight seals at each crack. When these pressure seals are combined with ThermaLock and custom-routed insulation, not only is energy efficiency enhanced, but it is also guaranteed that the insulation layer protects against air and moisture infiltration, maintaining the building’s health throughout its lifetime.
Custom-Profiled Rigid Insulation: Precision Efficiency
Polyiso rigid insulation boards, custom-routed to fit exactly with the GreenGirt CMH Z-girts and ThermaLock technology, are held together with composite pressure seals by A2P.
Standard insulation panels often require on-site modification, resulting in imprecise cuts and gaps that can also lead to thermal bypass. Custom-profiled rigid insulation addresses this issue through precise, factory-controlled manufacturing. Each panel is profiled to match exact building dimensions, virtually eliminating installation errors and unnecessary gaps.
Benefits of custom-profiled rigid insulation include:
- Precise Fit: Customized panels ensure exact alignment, minimizing potential gaps and eliminating thermal bypass and thermal bridging.
- Improved Thermal Performance: Accurate fitting maximizes thermal resistance and reduces energy waste.
- Faster, Easier Installation: Pre-cut panels streamline installation, reducing labor costs and project timelines.
Conclusion
Effectively eliminating gaps and cracks in insulation is critical for achieving peak building performance. GreenGirt CMH, SMARTci, ThermaLock technology, pressure seals, and custom-profiled rigid insulation from A2P collectively represent a significant advancement in insulation technology as they work together to eliminate thermal bridging and thermal bypass. For those committed to sustainability and performance, these solutions eliminate gaps and cracks and offer an effective, reliable path toward energy-efficient construction and long-lasting building resilience.

Frequently Asked Questions
How do you reduce thermal bridging with Z-girts?
Traditional metal Z-girts create continuous thermal bridges that compromise insulation effectiveness. GreenGirt CMH Z-girts use composite metal hybrid materials to limit heat transfer through structural components, and SMARTci adds structural support paired with custom-profiled rigid insulation to create a more continuous, “blanket” insulation layer that helps eliminate thermal bridging across the enclosure.
What is ThermaLock, and how does it stop air leakage behind rigid insulation?
ThermaLock is an integrated insulation-retention and sealing approach used with GreenGirt CMH Z-girts and SMARTci. It uses dual three-point compression seals to remove the air gap behind the insulation and stop air movement between the Z-girt and the insulation, reducing pathways for infiltration that can drive thermal bypass and performance loss.
How do SMARTci pressure seals and custom-profiled rigid insulation help eliminate gaps and cracks between insulation boards?
SMARTci compression pressure seals connect adjacent rigid insulation panels at butt joints to create added air- and water-tight seals at the “cracks” between boards. When paired with custom-profiled rigid insulation, the assembly reduces on-site cutting and helps minimize installation-related gaps that can lead to thermal bypass.
