Curtain walls are among the most complex and visible components of a building envelope. They protect interiors from water, air, and thermal intrusion while defining architectural character. Because of their size, integration points, and exposure to weather extremes, curtain walls are also prone to failures if not tested and verified. At ACE, our Curtain Wall Testing Services provide accredited and field-proven verification that these systems perform as designed, protecting both aesthetics and long-term building performance.
Unlike standard fenestration, curtain walls often cover large expanses of a building and must endure wind, thermal expansion, and seismic stresses. Even minor failures can lead to massive water intrusion, structural deterioration, and expensive disputes.
Our curtain wall performance testing ensures systems resist water, air, and structural loads while remaining compliant with FGIA and ASTM standards. By confirming performance before occupancy, owners and developers protect their investments and avoid the costly cycle of remediation.
Selecting the right test method is as important as the test itself. Organic field evaluation can misidentify failures, while some emerging technologies may overpromise and underdeliver. For a clear breakdown of different testing methods, limitations, and proper application techniques—including electrical and flood testing—see the Whole Building Design Guide’s Integrity Testing for Roofing and Waterproofing Membranes resource.
We provide a robust suite of field and laboratory testing services to verify performance under real-world conditions:
Using ASTM E1105 and AAMA 503 standards, we simulate wind-driven rain to assess whether curtain wall joints, seals, and transitions resist leakage. This ensures long-term moisture protection even under severe weather events.
Conducted in accordance with ASTM E783, this verifies that curtain walls meet performance thresholds for energy efficiency, comfort, and HVAC system balance. Testing helps confirm assemblies minimize uncontrolled airflow through facade systems.
Assessing framing, anchors, and glazing connections to verify curtain walls withstand anticipated wind and seismic loads without deformation or compromise. This provides confidence in both occupant safety and long-term durability.
Field inspections confirm that contractor workmanship aligns with design specifications and manufacturer requirements. This reduces risk of hidden deficiencies, strengthens warranties, and helps avoid future disputes.
Our reporting provides clear, defensible evidence of performance, protecting owners in warranty claims and contractors from liability exposure.
Each test is conducted with calibrated equipment, documented protocols, and detailed reports for defensibility.
Our Curtain Wall Testing Services have supported performance verification for:
These examples highlight the value of independent verification in protecting assets and reputations.
Curtain walls rarely function alone. They interact with roofs, podium decks, spandrel panels, and waterproofing systems. Our testing approach evaluates these transitions, ensuring curtain walls integrate seamlessly with surrounding assemblies. This prevents localized failures and ensures the entire building envelope functions as a unified, high-performance system.
Curtain walls define a building’s identity—but their complexity also makes them one of the most vulnerable systems. With ACE’s Curtain Wall Testing Services, you gain assurance that assemblies will perform under the pressures of real-world conditions.
