External venetian blinds are a modern, external sun shading system and consist of roll-formed aluminium slats, a top and end rail as well as lifting tapes and tilting tapes made of polyester.

  • ① Cover panel/box rectangular, round, square or built-in
  • ② Lateral guidance with tension cable or guide rail
  • ③ End rail with highly rigid profile
  • ④ Lifting tape made of specially coated polyester in black or grey
  • ⑤ Tilting tape/loop cord in black or grey
  • ⑥ Slats in various slat geometries and slat colours

Depending on the design, widths and heights of up to 5000 mm, a selection of drive variants and a range of additional equipment are all available.

The slats and all other aluminium parts of WAREMA external venetian blinds are powder-coated and can be specified in colours from the WAREMA Colour World. The available colours and finishes depend on the slat shape. Slat colours are grouped into three categories:

  • Selection colours: proven standard colours with a silk-gloss finish
  • Selection matt: selected colours with a matt finish
  • Choice colours: additional RAL colours, special colours and anodised colours

With the colour card for external venetian blinds and roller shutters, you get a quick overview of coordinated shades for external venetian blind slats and roller shutter profiles. This makes it easy to combine both systems with confidence.

WAREMA external venetian blinds are available with several slat shapes. They differ in geometry, function and application. Depending on the version, all slats are available in slat widths from 50 mm to 100 mm.

  • Edge-folded slats: stable, classic, cost-effective
  • Flat slats: reduced stack height (e.g. Windra flat slat 80 WF)
  • Blackout slats: maximum light blocking (e.g. Zetra slat 80 Z)

The choice of the cover panel depends on the installation situation and the desired façade appearance. The cover panels and all other aluminium parts of WAREMA external venetian blinds are powder-coated and can be specified in colours from the WAREMA Colour World . Optionally, all cover panels are available with integrated lintel insulation.

  • Angular cover panels: clear, understated look for modern façades
  • Round cover panels: soft lines for a restrained design
  • Square cover panels: compact form for cubic architecture
  • Plaster-in cover panels: for full or partial façade integration

Different brackets are available for fixing. End brackets with a single base plate or centre brackets with a double base plate enable simple and efficient installation while maintaining high stability. Telescopic versions of these brackets allow site tolerances to be compensated significantly faster and more accurately.

WAREMA external venetian blinds are generally guided at the sides in two ways, depending on requirements, installation situation and slat shape:

  • Guide rails: External venetian blinds with rail guidance are guided laterally via guide pins on the slats. This option is particularly wind-stable, robust and quiet in operation. A wide range of profiles can be integrated into almost any façade type: surface-mounted, on façades, concealed within façade installations or as a self-supporting solution.
  • Cable guidance: External venetian blinds with cable guidance integrate discreetly into the façade. The cables are polyamide-sheathed steel wire strands and are available in black or transparent. For optimal integration in different façade types, WAREMA provides a wide selection of brackets.

The selected guidance type influences stability, wind behaviour and the façade appearance. It is planned according to the installation situation, structural requirements and the architectural concept.

The guide rails and all other aluminium parts of WAREMA external venetian blinds are powder-coated and can be specified in colours from the WAREMA colour world.

From a classic crank handle to smart app control: modern external venetian blinds offer an operating solution for virtually any project.

WAREMA provides motorised drives with various standard motors as well as special motors for specific applications, for example:

  • Solar drive as an off-grid solution
  • SMI motors for building automation
  • Battery module UP when no mains connection is available
  • Fast terrace motor (STM), which raises the blind around 3× faster than a standard motor

The appropriate motor is selected to match the project-specific requirements. Detailed technical data for the available motor types can be found in the external venetian blind technical documentation.

WAREMA external venetian blinds can be expanded with well-designed supplementary accessories. This creates façade solutions that are functional, safe and consistent in design.

  • Safety and emergency escape route: WAREMA SecuKit auxiliary operation; battery-operated emergency retraction set / battery-supported solutions; motor with additional crank handle (ZHK)
  • Wind stability and application range: wind-stable versions; additional cable guidance; self-supporting systems
  • Daylight and comfort: daylight transport element (TLT); working position (switch spring); slowturn
  • Design and integration: VisioNeo Sun fall protection system; corner connectors; integrated lintel insulation; perforated slats; integrated insect and pollen protection

A basic external venetian blind can be integrated into virtually any facade. It is suitable for use with both new buildings and renovations. Thanks to the selection of different colours and slat geometries, you'll enjoy full creative freedom for your design. The basic external venetian blind is available with either cable or rail guidance.

What sets the top-mounted external venetian blind apart is its attractiveness and flexibility – all that is required to attach the blind to the window is a simple clip system. Together with the window, the blind can be installed in any structural opening. Compact dimensions allow it to be used even for small and medium wall openings.

Are you renovating and looking for an ideal external sun shading system solution? Then you need a WAREMA front-mounted external venetian blind.

Available in the three different S1, S2 and SE models, the external shaft venetian blind is the perfect sun shading system. It can be easily attached to exterior insulation and finish systems or other shafts – in a concealed or visible installation. And they are available in a wide range of colours.

No limits for visions: When it comes to s un shading systems on transom and mullion facades, architects, planners and the qualified specialists carrying out the work are tasked with striking the perfect balance between efficiency and elegance. The transom and mullion sun shading system with external venetian blinds and window awnings from WAREMA offer solutions to address these requirements.

With the new extension of the Freiburg District Court, the state of Baden-Württemberg has created modern spatial structures and a future-oriented working environment – as part of a sophisticated densification and a sensitive integration into the historic setting.

The implemented sun shading concept also plays a key role. WAREMA’s venetian blind systems are seamlessly integrated into the architectural design, combining functionality, safety and aesthetics.

Individual sun shading systems create a wonderful ambience inside and out. Whether the need to block out daylight or to let it in - every room has different sun shading requirements. The awning must also harmonise with the building in every respect.
