July 25, 2025 - THERM Analysis Summary
A full thermal analysis was conducted using LBNL’s industry-standard THERM software, confirming that the PortalWall® assembly exhibits zero condensation risk under design conditions.
Even at outdoor temperatures as low as 0°F, interior surface temperatures remain well above the dew point, ensuring dry, mold-resistant performance.
This superior result is attributed to the system’s underlying thermal logic—most notably, the elimination of vertical framing members, which are typically weak points in conventional facade systems. By removing these thermal bridges and integrating strategically placed heat sink and insulation layers, PortalWall® achieves a high-performance envelope that manages both energy and moisture with exceptional reliability.
Why PortalWall® Makes Sense—Economically and Technically
The additional cost to implement PortalWall® is not in materials—it's in mindset. Exchanging just one part for another.
- Cost-Neutral Design:
Integrating support structures with airflow openings does not increase cost. The base materials, panel geometry, and fastening approach remain fundamentally the same.
- INFORM & EDUCATE, Not Expense:
The only real lift is educating architects and engineers to adopt a smarter, airflow-conscious design. Once understood, it becomes standard practice—not an upcharge. WHO IS GOING TO ARGUE THAT PROMOTING AIR FLOW & EVAPORATION IS A POOR CHOICE.
- Reduced Remediation Risk:
If failure ever occurs, PortalWall® makes it easier to repair and can include sensing strategies to catch it early. This drastically lowers remediation costs compared to conventional walls, where moisture spreads unseen and uncontrolled.
- Net Economic Win:
No added material costs. Lower lifecycle risks. Fewer liability claims. Fewer callbacks. Better warranties. It’s a smarter system at the same price point.
PortalWall®: Built to Withstand, Designed to Perform in every CLIMATE ZONE
PortalWall®, with its advanced spandrel assembly, makes high-performance façade design not only possible—but inevitable.
No volume of rainwater PLUS wind pressure, will cause it to fail.
It’s rigid, it’s reliable, and it’s all tried and true—built on tested materials, patented logic, and real-world performance.
It’s engineered to channel, protect, and perform under the harshest conditions.
Thanks to our now patent-pending PortalWall® + Parallels™ configuration, we can integrate best-in-class thermal modules while keeping the assembly cool, dry, and structurally sound. Moisture stays out. Heat flows the way we want it to. Everything works in harmony.
This is DESIGN WISDOM.
PortalWall® was lab tested before it was conceived, built upon the proven performance of a Kingspan QuadCore® 4-inch-deep insulated panel—but improved upon, a panel with published thermal and structural data. From this strong foundation, the system was continuously improved and validated.
The true breakthrough lies in the patented enhancements described in U.S. Patent No. 10,329,758 B2—my first granted patent. These innovations structurally reinforce the panel without compromising its core integrity.
In fact, the design is so precisely engineered that the original manufacturer's warranty remains fully intact and carries forward with the PortalWall® system.
No Accommodations. No compromise. Just improvement.

- The panel is securely seated in a precision-formed trough, delivering unmatched structural stability.
- Stronger, lighter, smarter — with increased spanning capacity and enhanced moisture and vapor control.
- Despite the performance leap, GEN3 is more economical to process and install — reducing shop labor, site coordination, and overall cost.
Improved in every way — yet more economical than ever.
PH vs. PortalWall®
PortalWall®: Passive House, Reimagined
PortalWall® can be Passive House on steroids. It’s the critical layer Passive House often overlooks—the dynamic, structural, performance-enhancing core that ties everything together.
Designed by me, a practical engineering mind with a holistic view, cost careful, PortalWall® solves what others neglect:
- The opaque water-draining spandrel assembly
- The airflow logic that avoids mold and stagnation
Passive House is a target. PortalWall® is a better path.
It doesn’t just comply—it improves, integrates, and elevates.
So next time you hear “Passive House,” remember:
PortalWall® is what makes it real.
