Standard Information

  • Standard Number: EN 12207:2001
  • Title: Windows and doors - Air permeability - Classification
  • Status: Current
  • Application: Windows and doors in buildings

Classification System

Air Permeability Classes

The standard defines four classes based on tested air permeability:

  • Class 0: No performance determined
  • Class 1: 50 Pa (12.50 m³/h.m²)
  • Class 2: 100 Pa (6.75 m³/h.m²)
  • Class 3: 300 Pa (2.25 m³/h.m²)
  • Class 4: 600 Pa (0.75 m³/h.m²)

Reference Values

Air permeability is measured in:

  • m³/h per m² (relative to overall area)
  • m³/h per m (relative to joint length)

Testing Methods

Testing procedures include:

  • Positive pressure testing
  • Negative pressure testing
  • Air flow measurement
  • Pressure differential testing
  • Temperature and humidity monitoring

Application Guidelines

Recommended Classes by Building Type

  • Class 1: Basic buildings, storage facilities
  • Class 2: Standard residential buildings
  • Class 3: Commercial buildings, high-end residential
  • Class 4: Passive houses, high-performance buildings

Performance Factors

Key factors affecting air permeability:

  • Frame design and material
  • Sealing system quality
  • Hardware functionality
  • Installation precision
  • Maintenance condition

Benefits of Good Air Permeability

  • Improved energy efficiency
  • Better acoustic performance
  • Enhanced thermal comfort
  • Reduced condensation risk
  • Lower heating/cooling costs

Installation Requirements

  • Proper frame alignment
  • Correct sealing application
  • Appropriate fixing methods
  • Quality control checks
  • Professional installation

Important Considerations:

  • Select appropriate class for building type
  • Consider local climate conditions
  • Verify test certificates
  • Ensure proper installation
  • Maintain regular inspection schedule
