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
