Aluminium Escape or Exit Doors


Exit doors are designed to ensure the quick and easy exit from a building and equipped with exit hardware devices. Exit doors provide users of a building with a safe means of escape without compromising the security of the building by persons without authorisation. It is essential that the doors can be opened easily so that everyone can leave safely.

Design


  • Aluminium escape doors are usually constructed with thermally broken aluminium as standard. 
  • Consisting of an aluminium casement door equipped with escape hardware. 
  • Two types of escape hardware:  panic exit hardware and emergency exit hardware. Depending on the door functions, escape doors are equipped with panic or emergency exit hardware. 
  • Different colour and finish options for profiles: standard powder coated, textured metallic finishes, anodizing finished, etc.

Panic exit doors (BS EN 1125)


Being equipped with panic exit devices, panic exit doors are operated by a horizontal push bar for use in case of emergency escape. They are also called fire exit doors, fire escape doors or panic doors.  They are designed usually open outward in the direction of escape. 

Panic exit doors are used where:

  • Members of the public have access to the building but may not be familiar with the exit routes such as hospitals, hotels, cinemas, and stadiums. 
  • Any building that has more than 60 people in it.

Emergency exit doors (BS EN 179)


Being equipped with emergency hardware, emergency exit doors operated by a lever handle or push pad, for use in case of emergency. They are designed to open in the direction of escape. 

Emergency exit doors are used in buildings that are not open to the general public and occupied only by staff or other persons who are familiar with the exit doors and have been trained in emergency escape procedures. Some applications are listed below: 

  • Private residential complexes
  • School classrooms
  • Non-public administration buildings or industrial companies
  • Non-public areas of administrative buildings
  • Non-public areas of airports, banks, shopping centres

Size Limitations


  • A standard single casement door to be used as an escape door measures up to 1000mm at width and 2300mm at height. The door vent may weigh up to 120kg. 
  • Large size vent measures up to 1.4m at width and 3 metres at height. The door vent may weigh up to 150kg.

Opening options


  • Side-hung outward opening single door
  • Side-hung outward opening double door  
  • Options consisting of single or double doors combined side or top fixed lights.

Safety & Security Options


  • Aluminium outward opening side-hung windows usully comes with standard multi-point locking systems.
  • Burglar resistance classes of RC2 or RC3 are also available as security options,
  • PAS24 security options for outward opening windows at ground floor
  • Restrictor can be used to limit the amount of opening of the side-hung windows for safety.

Thermal Performance


  • Aluminium escape doors are usually constructed with thermally-broken frames to achieve higher thermal performance. Higher thermal performance, indicated by lower Uw-value, is achieved with lower U-values of frame (Uf), glass (Ug), and spacer bars (PSIG). 
  • For replacement in existing residential buildings, aluminium escape doors must achieve a Uw-value of 1.4 W/m2K or lower to comply with Part L of Building Regulations. ( A minimum Door Energy Rating of Band C  is also acceptable for the glazed doors ( have more than 60% glazed area) or Band B for other doors for compliance.
  • For new residential buildings, glazed aluminium doors (with greater than 60% glazed area) must have a Uw-value of 1.2 W/m2K, opaque aluminium doors (with less than 30% glazed area) and semi-glazed steel doors (with 30% – 60% glazed area) must have a Uw-value of 1.0 W/m2K to comply with Part L of Building Regulations. (The maximum allowed value for all doors is 1.6 W/m2K for SAP calculations)

Difference between a fire exit door and a fire door

Usually fitted inside the building, fire doors are specifically designed to prevent the spread of fire for a certain period of time, while fire exit doors, usually fitted on the exterior of the buildings, are designed to allow quick and safe escape from an occupied space.


Building Regulations for Doors

All doors installed in buildings must comply with the Building Regulations and meet the specified requirements:

  • Doors to be installed in new or existing buildings must meet energy efficiency requirements contained in Approved Document L.
  • In new residential buildings, easily accessible doors are required to meet the security requirements specified in Approved Document Q.
  • Doors must comply with ventilation requirements specified in Approved Document F.
  • Glazing in critical locations must meet the safety requirements specified in Approved Document K.
