Performance Standards That Define Every FOWALL Facade
Verified Metrics. Zero Guesswork.
A curtain wall specification is only as credible as the performance data behind it. At FOWALL, every facade system is tested and verified to internationally recognized standards — not promises, but documented performance across five critical dimensions.
International Curtain Wall Standards Framework
FOWALL curtain wall systems are developed, tested, and documented against the following standards bodies. Each project compliance matrix is tailored to local building code requirements and the architect performance specification.
Five Performance Dimensions — Engineered & Verified
Structural Performance
Designed for wind loads, building movement, and long-term stability. FOWALL uses 6063-T5 and 6061-T6 aluminum extrusions with mullions engineered to L/175 or L/240 deflection limits. Connection systems accommodate ±25 mm inter-story movement in seismic zones.
- Wind load per ASCE 7, AS/NZS 1170.2, or Eurocode 1
- ASTM E330 static pressure differential testing
- AAMA 501.4 dynamic wind load by aircraft engine simulation
Air Tightness
Multi-layer EPDM gasket system with closed-cell design and precision CNC extrusion (±0.2 mm tolerance) ensures consistent compression along the full profile length. Pressure-equalized drainage cavities reduce differential pressure across exterior seals.
- Benchmark: ≤ 0.3 L/s·m² at 300 Pa (ASTM E283)
- Lab ASTM E283 + field ASTM E783 / AAMA 503
- Corner and joint sealant detailing per ASTM C1193
Water Penetration Resistance
Four-layer water management: exterior rainscreen with pressure-equalized chamber, integrated drainage channels with weep holes at every transom, continuous internal air seal, and gravity-driven water evacuation.
- Benchmark: 5000+ Pa under ASTM E331 static + AAMA 501.1 dynamic
- Suitable for high-rise, coastal, and tropical applications
- At 100 m height, design wind pressure can exceed 3,000 Pa
Thermal Performance & Energy Efficiency
Configurable from standard to net-zero-ready systems achieving U-Value 0.27 W/m²·K. Frame thermal breaks from 24 mm to 34 mm polyamide strip with foam insert. Glazing options: double IGU Low-E argon fill to triple IGU dual Low-E krypton fill.
- Standard: 1.6–2.0 W/m²·K (double IGU, warm-edge spacer)
- High-Performance: 0.27 W/m²·K (triple IGU, krypton fill)
- Calculated per NFRC 100 + ISO 12631 area-weighted method
Acoustic Insulation
Asymmetric laminated glass configurations break sound wave coincidence. Wider IGU cavities (≥16 mm) improve low-frequency attenuation. Continuous gasket compression eliminates acoustic flanking paths.
- Benchmark: STC 45 dB (ASTM E90 / ISO 10140-2)
- Acoustic sealant and mineral wool at slab edge perimeter
- Meets requirements for offices near transportation corridors
Safety & Durability — Engineered for 30+ Year Service Life
Engineered Aluminum
Project-specific aluminum profiles selected according to structural requirements, environmental exposure, and applicable building standards. Material certificates and traceability documentation available.
Surface Finishing
PVDF architectural coating (AAMA 2605, 70% resin), architectural powder coating (AAMA 2604 / Qualicoat Class 2), and anodized finish (AAMA 611 Class I, 20–25 μm).
Quality-Controlled Fabrication
Incoming material verification, extrusion dimensional inspection, surface finish testing, CNC machining accuracy control, and final assembly inspection before protective packaging.
Testing & Quality Assurance — Four-Stage Verification
Engineering Review
Wind load calculation, structural analysis, material specification, and thermal modeling.
Calculation package + compliance matrixPrototype Verification
Full-size mockup testing at accredited third-party lab per ASTM/AAMA/AS standard.
Test report with pass/fail criteriaProduction QC
Extrusion dimensional check, finish inspection, CNC machining accuracy, and assembly verification.
Batch inspection recordsPre-Shipment Inspection
Visual inspection, dimension verification, packaging integrity, and documentation completeness.
Final inspection report + packing listRegional Standards Adaptation
FOWALL configures each curtain wall system to the project governing code and site conditions — not to a catalog template.
Location + Building Height
Wind load calculation per ASCE 7, AS/NZS 1170.2, or Eurocode 1
Climate Zone + Exposure
Water penetration rating, corrosion protection spec, glazing SHGC selection
Governing Standards
Standard-by-standard compliance matrix (ASTM, AS/NZS, Eurocode, etc.)
Seismic Design Category
Inter-story drift accommodation design with verified displacement tolerance
Why Specify FOWALL Curtain Wall Systems
Engineering-Led, Data-Backed, End-to-End
Every FOWALL system is developed by engineers who understand how facades perform — not just how they look. Performance data, not marketing language, supports every claim on this page. From aluminum extrusion through fabrication, assembly, and shipping — quality is controlled end-to-end under one system.
