Wind Load Resistance in Windows and Doors
Standard: EN 12210:2001
Standard Information
- Standard Number: EN 12210:2001
- Title: Windows and doors - Resistance to wind load - Classification
- Status: Current
- Application: Windows and doors in buildings
Classification System
Wind Load Classes
The standard defines classes based on test pressure:
- Class 1: 400 Pa
- Class 2: 800 Pa
- Class 3: 1200 Pa
- Class 4: 1600 Pa
- Class 5: 2000 Pa
- Exceptional: > 2000 Pa (Special requirements)
Relative Frontal Deflection
Deflection classes:
- Class A: ≤ 1/150
- Class B: ≤ 1/200
- Class C: ≤ 1/300
Testing Requirements
Testing procedures include:
- Positive and negative wind pressure tests
- Repeated pressure tests
- Safety tests at 1.5 times design pressure
- Deflection measurements
- Air permeability verification
Application Guidelines
Recommended Classes by Building Height
- Class 1: Low-rise buildings (up to 10m)
- Class 2: Standard residential (up to 15m)
- Class 3: Multi-story buildings (up to 25m)
- Class 4: High-rise buildings (up to 50m)
- Class 5: Tall buildings (up to 100m)
- Exceptional: Skyscrapers and special applications
Performance Criteria
Products must maintain:
- Structural integrity
- Operating functionality
- Safety characteristics
- Air permeability classification
- Water tightness performance
Factors Affecting Performance
- Building location and exposure
- Installation height
- Door/window size
- Frame material and design
- Glazing specifications
- Hardware quality
Installation Considerations
- Proper frame anchoring
- Appropriate fixing methods
- Sufficient support systems
- Correct sealing techniques
- Consideration of building movement
Important Considerations:
- Select class based on building height and location
- Consider local wind load requirements
- Verify certification documentation
- Ensure proper installation methods
- Regular maintenance and inspection
