WAREMA External Venetian Blinds

Exterior sun shading of windows using WAREMA external Venetian blinds enormously reduces the amount of solar radiation entering through glass, in some cases by up to 90% thereby maintaining a relaxing, comfortable interior environment. Preventing direct radiation, yet admitting reflected light, external venetians create light-filled working or living spaces reducing the need for artificial lighting throughout the day. An external view and connection to the exterior is maintained on demand through tilted venetian slats whilst privacy is preserved. When light levels drop external venetian blinds can automatically retract fully out of sight. This feature also provides easy access to the glass for cleaning. 

The shallow curve of the blade surface perfectly compliments the fine lines of modern architecture. Guiding the slats is achieved using slimline extruded aluminium rails or coated stainless steel cables.

WAREMA blinds feature the most extensive range of custom components available to adapt blinds to any building application.

The many proven benefits of using external venetian blinds for sun shading along with their engineered components for high reliability will more than offset any initial capital investment.

Key Features & Benefits

  • High radiation reflection, low radiation absorption and  low radiation transmission values means less heat entering inside.
  • Fully retractable venetian blinds allows maximum light in low light conditions and easy access to the glazing for cleaning.
  • Easily coupled to Warema control systems to adjust for temperature, wind, rain, humidity and a host of other functions.
  • Infinitely adjustable to cater for all sun conditions.
  • Aluminium and stainless steel components for long service life.
  • Marine grade textile elements requiring minimum maintenance.
  • Good wind stability and retractable for protection in stormy conditions.
  • Intelligent control when used with a WAREMA control system.
  • Broad range of slat styles and widths for different situations. 
  • Daylight without heat gain.
  • Able to be integrated into concealed building facade recesses for a low visual impact when retracted.
  • Low embodied energy in manufacture.

Applications

  • Commercial buildings low to mid rise.
  • Environmentally Sustainable Design (ESD) projects.
  • Double skin façade projects.
  • Upgrade of existing buildings to meet energy reduction compliance.
  • Offset from the glass applications (with reduced wind threshold settings).
  • Public buildings.
  • Internal applications, particularly retail display areas.
  • High rise internal applications.

Drive Options

  • Driven either by a crank handle or integrated 240v motor.
  • For simple applications, motorised blinds can be operated by a up-down wall switch or programmable remote control.
  • Motorised blinds can also be operated by Warema basic centralised control systems or highly sophisticated control systems for major projects.  Warema control systems allow automated functionality from simple up/down on a timer, to automated responses in environmental changes e.g. sun-tracking, wind threshold/direction, temperature, rain and many others.  For an overview of the available functions see our Control Systems Overview.
  • For large commercial we also have highly sophisticated and programmable LONworks and KNX-EIB systems.  For more information contact us.

Blade Profiles & Information

Rolled Edge Blade

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 degrees.

Key Features

  • Suitable for most applications.
  • 60 or 80mm wide blades.
  • Extensive color selection available.
  • Special colors can be manufactured for large projects.
  • Highly wind-stable (12-15 m/s).
  • Daylight guidance feature available.
  • Ladder locked slats.
  • Extensive customizable features.
  • Wide span between support cables.
  • Guide rails or guide cables.

Applications

  • Residential and commercial sun shading of vertical glass.
  • Office environments.
  • Environmentally Sustainable Design (ESD) buildings for Green Star compliance.
  • “Off the glass” applications (with reduced wind threshold settings).
  • Self-supporting version available.

Flat Blade

Flat blade profile features a fine edge slat that barely interrupts the view and stacks into a compact space. The blades are manufactured from a special flexible aluminium alloy that spring-returns to shape if deflected in wind.

Key Features

  • Small packet/stack size.
  • 50, 60, 80, 100, 150 mm slat widths available.
  • Special flexible alloy slat material.
  • Extensive color range available.
  • Special colors can be manufactured for large projects.
  • Good wind stability (10-12 m/s) when installed close to the glass.
  • Daylight guidance feature available. “Daylight guidance” means that a Warema control system makes automatic adjustments to slats throughout the day, which keeps internal levels consistent, without excess glare.
  • Ladder locked slats.
  • Extensive customizable features.
  • Tilts through 80 degrees.
  • Perforated slats are available.
  • Guide rails or guide cables.
  • Self supporting version available.
  • “Design” version available.

Applications

  • External sun shading of vertical glass for residential and commercial buildings.
  • Office environments.
  • Environmentally Sustainable Design (ESD) buildings for Green Star compliance.
  • Windows with no (or limited) space available for stacking of the slats.
  • Double skin façade projects.
  • Internal glare control for retail applications.
  • Façade compositional elements.

Dim-out Slat

Warema’s dim-out profile offers the rigidity of a rolled edge slat with a unique special interlocking shape that greatly reduces daylight. Each slat is formed with a rubber insert that creates a gentle seal between slats. Two slat widths and a range of tailored components allow dim-out blinds to adapt to a multitude of building types and construction methods.

KEY FEATURES

  • Unique S shape with noise-deadening rubber inserts.
  • 63 & 94 mm slat widths available.
  • Multifold shape provides excellent rigidity.
  • Extensive color range available.
  • Special colors can be manufactured for large projects.
  • Daylight guidance feature available.
  • Special ladder cords that provide complete slat closure.
  • Optional light diminishing channels to enclose slat ends.
  • Extensive customizable features.
  • Tilts through 180 degrees.
  • Sound attenuation.
  • Self-supporting version available.

Applications

  • External sun shading of vertical glass for residential and commercial buildings where a higher degree of light protection or privacy is required.
  • Presentation rooms where AV equipment is used.
  • Laboratories.
  • Environmentally Sustainable Design (ESD) buildings for Green Star compliance.
  • Locations subject to excessive glare from adjoining facades.
  • Noisy locations.

Cedar Slat

Our cedar slat version offers the significant benefits of external sun shading combined with a warm natural appearance. Premium Western Red Cedar is coated with SIKKENS clear finish to enhance the natural colors and provide long lasting protection. Over time the color will soften to grey, harmonizing with other timber elements of the design.
