External Systems

Self-Supporting External Venetian Blinds

The slats of self-supporting external venetian blinds run in a structural guide rail that supports the pelmet and eliminates the need for a pelmet fixing point. A range of rail profiles and pelmet designs provide different visual effects and serve to express the blind as a bold façade element. It is therefore often used to add depth and colour to a facade. The self-supporting type can be utilized with all blade profiles and drive types.

Key Features
  • Highly rigid guide rails minimize fixing points to facade
  • Suitable for all blade profiles
  • Easy planning and installation
  • Bold façade elements
  • Choice of pelmet designs
  • Daylight guidance feature available
  • Projects where the blind pelmet is situated in front of the glass
  • Vertically framed curtain facades
  • Designs where guide rails and pelmet are to be expressed
  • Designs where only end fixing of guide rails is possible
  • Guide railed applications set at a greater distance from the façade

Wall-Integrated External Venetian Blinds

This specialized form of external venetian blind is designed to be incorporated within the wall structure during construction. The module is encapsulated in a sealed cfc free polystyrene case to minimize heat transfer and is an ideal solution for buildings in alpine and cooler climates. For warmer climates experienced in most of Australasia a standard venetian type using a soffit recess created on site is the normal solution.

The facade integrated modules also feature an extremely low stacking depth when the offset head rail version is used. A roller insect screen can be integrated.

Key Features
  • Concealment in the soffit or head of window reveal.
  • Minimal heat loss through housing.
  • All slat profiles are available.
  • Energy efficient buildings for colder climates.
  • Insulated timber framed buildings with sheet cladding.
  • European style concrete inner shell buildings.
  • Alpine projects.
  • Applications where minimal stacking depth is available.
Slat profiles available
  • Rolled Edge Slats

    Rolled edge profile is the most popular style due to its concave-convex blade with the advantage of a rolled over edge for extra wind stability. The blade rotates through 160°.
