EN 12179:2000

Overview

EN 12179:2000 is a European standard published by CEN that specifies the test method for assessing the resistance of curtain walling systems to wind load. This standard focuses on both fixed and openable parts of curtain walling, evaluating their structural performance under positive and negative static air pressure. It applies to all curtain walling products as defined in WI 00033238, ensuring safety and durability across diverse façades exposed to wind forces.

Curtain walling plays a critical role in modern building envelopes, acting as an outer covering that resists environmental loads but does not carry any structural load from the building itself. EN 12179 defines a uniform approach to testing their wind load resistance, helping manufacturers and designers validate product performance and comply with building regulations.

Key Topics

• Wind Load Resistance Testing
  The standard outlines procedures for simulating wind pressures on the curtain wall surface both inward (negative pressure) and outward (positive pressure), to verify the strength and stability of the façade system.

• Applicable to Fixed and Openable Elements
  EN 12179 covers all components of curtain walling, including mullions, transoms, panels, vents, and windows, providing comprehensive evaluation of the entire curtain wall assembly.

• Static Air Pressure Application
  Testing is based on static air pressure rather than dynamic or fluctuating loads, establishing baseline resistance characteristics under controlled conditions.

• Scope of Curtain Walling Products
  Defines curtain walling consistent with specifications in WI 00033238, enabling broad applicability across different designs, materials, and installation methods.

• Test Method Consistency
  Establishes internationally recognized procedures to ensure repeatability and comparability of test results, supporting quality assurance worldwide.

Applications

• Building Façade Design
  Architects and engineers rely on EN 12179 to select curtain wall systems capable of withstanding local wind loads, contributing to safe, resilient building envelopes.

• Product Certification and Compliance
  Manufacturers use this standard for product development and certification testing, demonstrating conformity with regulatory requirements for wind load resistance.

• Quality Control in Production
  Routine testing according to EN 12179 helps monitor and maintain manufacturing quality, preventing structural failures due to inadequate wind load performance.

• Retrofit and Renovation Projects
  Testing existing curtain wall installations can identify weaknesses and guide upgrading strategies to enhance wind resistance.

• Building Code Enforcement
  Authorities reference this standard as part of compliance verification for high-rise buildings and structures exposed to significant wind pressure.
