Within the range of external venetian blinds , they can be specified with different widths, guidance systems and colours. Compare the available external venetian blind slat types to select the required function and façade appearance.

Suitability depends on window dimensions, guidance, wind loads and the selected product.

  • slender appearance for a restrained façade design
  • adjustable daylight, glare and privacy
  • compact slat stack, depending on slat width and system
  • rail or cable guidance in compatible configurations
  • colour coordination with windows and visible aluminium components

Flat slats in different widths

WAREMA offers flat slats in different widths. The appropriate width depends on the window format, façade grid, required stack height, view out and selected product.

Rail or cable guidance

  • rail guidance provides defined lateral guidance and is selected according to the system and wind loads
  • cable guidance supports a slender visual appearance where the product and project allow it

The fixing, reveal, dimensions, wind loads and required appearance determine which guidance is suitable.

Windra flat slats are designed for selected installations with higher wind exposure. The permissible operating limit depends on the blind dimensions, guidance, fixing, installation position and tested product configuration.

Planning criteria include:

  • slat and guidance configuration
  • unit width and height
  • wind exposure at the building
  • permitted values in the technical documentation

Coordinate slats with the façade

The external venetian blind colours can be coordinated with window frames, guide rails, cover panels and other visible building components. Available combinations depend on the selected product.

Surface finish

Matt and silk-gloss surfaces produce different visual effects. Use current product documentation and physical samples to assess the final colour and finish.

You can view products and operating options at Sunlight Experience Centres or contact a WAREMA specialised retailer. The retailer can assess the installation, take measurements, prepare a quotation and arrange professional installation and service.
