External Venetian Blinds

External Venetian Blinds are all about creating comfortable, energy-efficient internal spaces:

Heat gain through glass can be reduced by up to 90% (depending on glazing, window specifications and other factors), which keeps the internal temperature more consistent and cuts down on the need for air conditioning
Occupants can still enjoy the view out whilst controlling the intensity of natural light via the tilting slats; daytime lighting costs are greatly reduced
In winter, external venetian blinds act as an insulator, helping to conserve heat and reduce artificial heating
Combined with sophisticated climate monitoring and automation, external venetians become a living element of the facade, adapting and moving to maintain optimum light and internal comfort
Venetian slats serve the dual purpose of modulating sunlight and creating privacy
Special slat types are available for meeting a variety of sun-shading scenarios
External Venetian Blinds are designed to complement the look of most architectural designs

Available Slat Profiles

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°.

Flat edge 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.

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.

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.
