EN 13830 is the harmonized European standard for curtain walling systems.
It defines unified requirements and test methods for façade performance, safety, and durability — serving as the foundation for obtaining the CE marking under the EU Construction Products Regulation.
① Market Access – A “passport” for entry into the EU and markets recognizing European standards.
② Performance Assurance – Sets objective benchmarks for air, water, wind and impact resistance.
③ Quality Symbol – Represents engineering excellence and product reliability.
Product Tested: GL50 Stick Curtain Wall System
Testing Organization: Intertek Testing Services
Test Type: Full-scale mock-up testing
Testing was performed according to the EN standards specified in the bid documents. The SunFrame GL50 Curtain Wall Series successfully met or exceeded all required performance levels.
Performance Category | Test Standard | Classification / Result | Client Value Interpretation |
Air Permeability | EN 12152 & EN 12153 | Fixed units: Class A2 Operable units: Class 4 | Achieved the highest standard classification. Air tightness is excellent under test conditions, effectively reducing air infiltration and helping lower building energy consumption. |
Water Tightness | EN 12154 & EN 12155 | Class R5 (highest) Test pressure: +300 Pa Result: No leakage | Under simulated heavy rain and wind conditions, no water penetration was observed during testing, effectively protecting interior finishes and structural elements. |
Wind Load Resistance | EN 12179 & EN 13116 | Design pressure: ±2200 Pa Ultimate pressure: ±3300 Pa (150%) Result: Structure remained intact, no permanent deformation | Provides substantial safety margin for high-rise or coastal buildings. The system maintained structural integrity under extreme wind loads in testing. |
Impact Resistance | EN 12600 & EN 14019 | Pendulum impact test Drop height: 950 mm Result: No breakage, no falling, function maintained | Demonstrated the ability to withstand accidental impact without component detachment, maintaining façade integrity under tested conditions. |
The GL50 Stick Curtain Wall has been successfully applied in different climates and architectural contexts.
Below are two examples that highlight its reliability and adaptability in practice.
Pegasus Hotel, Guyana
For this landmark hospitality project in the Caribbean, SunFrame’s GL50 system was selected to cope with high humidity, intense sunlight, and seasonal storms. Its precise joint control and robust sealing maintained façade integrity while supporting a clean, modern design.
Mahi Project, Philippines
In the coastal city environment of the Philippines, the GL50 curtain wall system delivered stable performance under high temperature and salt exposure.
At SunFrame, performance data drives every design decision. The GL50 Stick Curtain Wall has been proven through full-scale EN 13830 testing by Intertek, with clear results for airtightness, water tightness, wind load, and impact resistance.
These results reflect more than compliance—they confirm that our façades can withstand real-world challenges, from heavy storms to high winds, while maintaining structural stability and occupant safety. By combining robust engineering, precise fabrication, and rigorous testing, SunFrame delivers curtain wall solutions that architects and developers can confidently rely on demanding international projects.
