  • Air tightness: Class 4 (600 Pa)
  • Water tightness Class 9A (900 Pa)
  • Wind load resistance: Class C4 (1600 Pa)

Aluminium lift&slide doors to be installed in residential properties are subject to the building regulations:

  • Sliding doors to be installed on the ground floor of new residential buildings have to comply with PAS24 security level. (Building Regulations Part Q)
