External Venetian Blinds

Rolled edge (also known as beaded slats) 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.

Warema's new Zetra slat perfectly embodies the current architectural trends and impresses with its improved functionality in terms of dim-out capability, wind stability and room illumination. The Zetra slat 80 Z for external blinds received the Red Dot Design Award 2022 for its excellent design.

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.
