Slanted vertical blinds for gable windows & custom shapes

Windows don’t always have to be rectangular; on the contrary, slanted windows, gable windows, trapezoid windows, triangular windows, and other special shapes give buildings a unique and individual appearance. Inside, you can achieve perfect privacy and sun protection with slanted vertical blinds – also called slope systems – while adding great design accents. Determining the right size and installing them is much easier than you might think.

On this page, we have therefore summarized everything you need to know about the possible types, sizes, and operating options for slanted vertical blinds.

Sizes of slanted vertical blinds from KADECO

Even with our slanted blinds, you can choose between slat widths of 89 mm and 127 mm. This determines the maximum size of the vertical blind:

With 89 mm slats, the maximum height is 300 cm with a maximum rail length of 495 cm.
With 127 mm slats, the maximum height is 450 cm with a maximum rail length of 600 cm.

For both options, the maximum tilt angle is 55°. As you can see, even for very large windows, you can find a suitable slanted vertical blind.

Colors and Design

Of course, vertical blinds primarily provide privacy and glare protection; but isn’t it even better if the blinds also enhance the room? With KADECO’s slanted vertical blinds, you have almost endless design possibilities. It starts with the color of the guide rails: in addition to the standard colors white, black, anthracite, and window gray, you can choose your own custom colors.

And with the huge selection of slat colors and patterns, you are sure to find your favorite. You can even equip your blind with slats in alternating colors to create a unique, personalized piece.

Operation options and additional features

The practical DuoLine control allows easy adjustment via a cord, while the slats can be tilted using a chain. Alternatively, the OneLine control in straight vertical blinds combines both functions into a single chain. Importantly, the chain breakaway system according to DIN EN 13120 ensures optimal safety, making the vertical blinds suitable even for children’s rooms.

Even more convenient are the motorized slats of the ElectricLine. You can have the control element installed on either the high or the low side. Details on motorization and possible Smart Home integration can be found here:

The room in House Gilead IV of the Evangelical Clinic Bethel, transformed from a dining hall into a lecture hall, offers a very special atmosphere. The high, elaborately decorated ceiling, the perfectly staged lighting concept, and the large window fronts make the spacious room appear magnificent and bright. Motorized vertical blinds from KADECO were installed as sun and glare protection, allowing individual control of the light at each window. The color variation within the blinds reflects the diversity of the various warm tones in the room and integrates perfectly into the overall design.
