Made-to-measure external venetian blinds
An external venetian blind (raffstore) stops the sun in front of the glass, before the room heats up. The slats let you control how much daylight comes in: slightly tilted, the room stays bright and the view outside stays open; fully closed, the slats keep out heat and prying eyes. When raised, the blind disappears into a compact stack at the top of the window. Every blind is made to your measurements – the configurator shows the price as soon as you enter width and height.

Blackout external venetian blinds, fitted with 90 mm wide S or Z slats, for darkening with guide rails or cable guidance – order in our shop. As early as 30 years ago it was recognised that external venetian blinds can achieve a high blackout effect thanks to a special curvature of the slats, if they are shaped differently from a C-slat. The oldest blackout external venetian blinds are probably the Z-slats, which have a somewhat industrial, angular look. The S-slats are more harmonious and blend in more softly with the façade. Very high heat and light shielding. Properties of S and Z slats as blackout slats: good darkening in the slat area good prices, made in the EU high wind stability thanks to the special curvature Somfy drives for motorised versions crank operation available angled pelmets available large choice of colours reasonable delivery times good workmanship and quality thanks to fully automated production no shipping abroad (German addresses only) These colours are available. The spacers for the guide rails. All stack heights for all 4 slat types. Height = overall blind height including head rail. Blind height for 90 mm S-slats and 90 mm Z-slats with crank operation 60 cm 135 mm stack 135 mm stack 80 cm 145 mm 145 mm 100 cm 155 mm 160 mm 120 cm 170 mm 170 mm 140 cm 175 mm 180 mm 160 cm 190 mm 190 mm 180 cm 200 mm 205 mm 200 cm 215 mm 215 mm 220 cm 220 mm 225 mm 240 cm 235 mm 235 mm 260 cm 245 mm 250 mm 280 cm 255 mm 260 mm 300 cm 265 mm 270 mm 320 cm 275 mm 280 mm 340 cm 290 mm 295 mm 360 cm 300 mm 305 mm 380 cm 305 mm 315 mm For motorised blinds the stack is 20 mm higher. Example calculation: Cover plate height: e.g. for 90 mm S-slats, external venetian blind height with motor = 220 cm = 220 mm plus 20 mm for the motor plus 20 mm recommended overlap = cover plate height 260 mm.
These economical ECOsaver external venetian blinds are available with 80 mm beaded slats or 80 mm flat slats. As well as C slats, Z slats and S slats are available on request. Buy online from a wide range. Anyone building a house and looking for external venetian blinds keeps wondering how the enormous price differences come about. Besides brand-related pricing, production location has for some time played a central role in the pricing of external venetian blinds. The same situation has existed for years with roller doors and roller shutters and makes it impossible for consumers to understand the huge price differences. To meet demand, we now also offer economical alternatives of this kind: quality from the Czech Republic. How to measure and order The order sizes of external venetian blinds are always finished sizes of the entire construction. For the width, this means outer edge of guide rail (with rail guide) or outer edge of slat (with cable guide). For the height, the order size is top edge of head rail to bottom edge of bottom rail = order height. For recess fitting, measure the recess and deduct 1–2 cm if you want to screw the blind to the window frame using spacers. If you want to fix the rails directly to the side of the reveal, first check carefully that the measurements at the top, middle and bottom are the same. The narrowest recess measurement is then the order width. For fitting in front of the reveal, please add the side overlaps (5–8 cm recommended). For the height, the stack height must be added. Below are the stack heights with motor drive and 80 mm beaded slats: Stack heights with crank operation are 20 mm smaller. Smallest stack heights possible with the 80 mm flat slat and cable guide: up to 100 cm blind height = 145 mm stack height up to 120 cm blind height = 150 mm up to 140 cm blind height = 155 mm up to 160 cm blind height = 160 mm up to 180 cm blind height = 165 mm up to 200 cm blind height = 170 mm up to 220 cm blind height = 175 mm up to 240 cm blind height = 180 mm up to 260 cm blind height = 185 mm up to 280 cm blind height = 190 mm up to 300 cm blind height = 195 mm up to 320 cm blind height = 200 mm up to 340 cm blind height = 205 mm up to 360 cm blind height = 210 mm up to 380 cm blind height = 215 mm up to 400 cm blind height = 220 mm Stack heights with crank operation are 20 mm smaller. Cover panels are made 25 mm higher than the stack height as standard.

Order external venetian blinds with 50 mm aluminium slats here – small stack heights, a wide range of uses and many drive options. High-quality Reflexa® external venetian blinds with 50 mm aluminium slats, crank or motor operation, made in Germany and of the latest generation (180 degree tilt). At the bottom of this page (below the colours) you will find detailed technical descriptions and PDFs to print out. Prices for external venetian blinds with 50 mm slats are slightly lower than for the wider, flanged slats. Order in our shop and configure your new external venetian blind. The picture above shows the Reflexa® EMA 50 endless cord blind, which carries out all functions – tilting the slats as well as raising and lowering the blind. During installation the cord is led through the window frame (drill a hole through the frame or wall beforehand) and operated via a deflection pulley (included in the delivery). For endless cord gears and crank drives we always make the gear flush with the head rail. The pictures show the gear protruding. Changing from "flush" to "protruding" is easy during installation. Reflexa® endless cord operation is the best-selling version for 50 mm slats. Endless cord gears are an economical version of the external venetian blind. - 50 mm external venetian blinds are available with endless cord gear, crank drive, motor drive or radio-controlled motor; the manufacturer is always Reflexa. Reflexa® motor operation Crank operation We offer 50 mm slats up to a width of 500 cm (cord pull up to 300 cm width, endless cord gear up to 250 cm, crank and motor up to 500 cm width) and a maximum height of 360 cm. For larger blind sizes, please choose the 60, 80 or 88 mm slats, which are flanged at the sides. For protection against wind and weather, the 50 mm blinds can be made with lateral tensioning using a nylon-coated steel wire. For widths over 200 cm we recommend an additional central guide wire (wind protection). To cover the head rail and the slat stack when the blind is raised, an angle cover plate in a matching RAL colour can be fitted on top. The endless cord gear is durable and maintenance-free. Ladder tapes made of 100% Terylene. Head rail always in natural silver, 57 x 51 mm or 40 x 30 mm depending on the drive type. Bottom rail 51 x 20 mm, coated in a colour of your choice. Please note*: with small widths, the blind may hang slightly askew; this cannot be avoided. Please note: all order sizes are finished sizes of the blind, i.e. outer edge of slat to outer edge of slat = order width, and top edge of blind to bottom edge of bottom rail = order height of the finished blind. Wall fitting, so that the raised slat stack is out of the window's field of view. Side caps are required for the cover plate, see configuration. Order height (outside) = window opening height plus stack height plus 3 cm = order height of the external venetian blind Fitting options: ceiling, wall, recess Please note that only our measuring guide is binding for you. Any different measuring guides from manufacturers are not valid. We have written ours to be as easy as possible for a non-specialist to follow. If you have any questions, please call our telephone hotline. The following slat colours are available. Other slat colours can be supplied on request at no extra charge – just ask. Head rail always in silver. The bottom rail and tensioning brackets of the blind are silver, dark grey or white as standard. All other colours are available at a surcharge, see configurator. We are happy to send you the stack heights and specifications of the individual slat types on request.
Self-supporting sloping external venetian blinds are particularly suitable for fitting to glass façades and low-energy houses. Sophisticated shading for special fitting situations. This type of shading is needed where the building does not allow fitting directly to the façade or window frame. The complete construction consists of the sloping external venetian blind, guide rails and pelmet. An electric motor drives the blind and controls the tilting of the slats. The bottom rail is a telescopic rail that automatically shortens and lengthens as the blind moves up and down, depending on the angle required. This blind is only available with guide rails. Double, reinforced guide rail brackets hold the complete system and the factory-fitted U-shaped pelmet. Details and features: fitted with 80 mm nipple-guided flat slats, available in many colours available with an inclination of up to 45 degrees (full list at the end of this page) ELERO 230 V motor as standard radio control possible U-shaped square box pelmet to cover the slat stack included as standard (round version on request) side caps for the pelmet included as standard fully pre-assembled and ready to fit double guide rail brackets in various sizes guide rails, pelmet, bottom rail and spacers available in any colour at no extra cost guide rails available in round or square design guide rails always inside the pelmet Horizontal and vertical sectional drawings are provided below to help you with measuring.

The Asyflex sloping external venetian blind is the ideal external sun protection and privacy solution for sloping windows and other special shapes. The Reflexa AsyFlex sloping external venetian blind is a versatile slat system. Thanks to a patented telescopic rail, windows and glazed areas with a pitch of up to 45 degrees can be shaded. Sloping external venetian blinds are becoming increasingly popular. Despite their high cost, they are almost indispensable in summer. They can be used in many different situations and you can configure them online with us. Sloping shading can be made as a roller shutter or as a venetian blind. Both systems are always electrically operated. For many years Reflexa® has been a pioneer in developing these complex external shading systems for sloping windows. Use our configurator and you will receive a competitive online price immediately. New: from 04/2026 the Asyflex 80 SMS can be ordered as a quick-fit system. Winner of the 2015 Innovation Award at the R+T trade fair. New: Asyflex with rail guide (nipple guide). The adjustable slat positions of the sloping external venetian blind allow almost unlimited control of incoming light. The adjustable aluminium slats look light and unobtrusive, which also makes them ideal for conservatories and glass extensions. They can be set anywhere from closed through half open to fully open. The AsyFlex sloping blind can also be combined with a matching straight external venetian blind. We are happy to advise you on planning. Design your façade without compromise. The wide choice of colours lets you combine the slats, pelmets and telescopic rails as you wish. Standard rails are T-groove guide rails. Blackout rails S70 are available as an option. Further features of the sloping external venetian blind: The slats are made from a curved special aluminium strip with a lightfast, corrosion-resistant paint finish. Available as an 80 mm flat slat (up to 270 cm width with rail guide). To cover the slat stack when the blind is raised, we can supply an L-shaped or U-shaped cover plate in a matching colour. For fitting in front of the house wall, the cover plate is supplied closed at the sides (with side caps). For fitting in the reveal, a cover plate open at the sides is recommended. Details of the Asyflex blind: the blind is guided at the sides by a stainless steel rod or by 25 x 25 mm side rails (80 mm slats only). Supplied as standard with a high-quality 230 V mains motor. The drive is pre-installed out of sight in the head rail. Delivery within Germany is free of charge, using the manufacturer's own vehicles at no risk to you. We deliver throughout the EU and to Switzerland. The production sizes are derived from these measurements (geometric shape). Deductions are made at the factory. When fitting in front of a reveal opening (on an open house wall), please allow for the necessary overlaps all round and for the stack sizes. All order sizes are finished sizes of the blind. The type of fitting must be selected in the configurator; this determines whether deductions are made or the sizes are taken as finished sizes. If you make your own deductions for fitting in the reveal, please note that this also changes the diagonal of the geometric shape, which in turn changes the heights accordingly. If you make a deduction from the base width, a new geometric shape must therefore be measured vertically upwards, which will not match the net dimensions of the actual reveal.

External venetian blind or roller shutter?
Both are fitted outside and keep heat out. The difference is light: a roller shutter closes the window completely and the room goes dark. With an external venetian blind the slats tilt – you get shade and still keep daylight. That is why venetian blinds are popular for offices, living areas and large glazing, while shutters are often chosen for bedrooms. If you still want good darkening with a venetian blind, choose Z or S slats.
Crank, motor or solar?
With a crank you operate the blind by hand from inside. With a motor it moves at the push of a switch or with a radio remote. The solar drive needs no power cable to the window – a solar panel charges the battery, which makes retrofitting especially easy. The configurator shows which drives are available for each model.
Measuring correctly
For each model the configurator asks whether you are entering the clear opening in the reveal or the finished size in front of the reveal. Measure width and height at several points and use the smallest value in the reveal, or the required finished size in front of the façade. Notes and drawings are on each product page. For special shapes such as sloping windows, please contact us before ordering.
Frequently asked questions about external venetian blinds
Can I retrofit an external venetian blind?
Yes. There are versions for mounting in front of the façade or in the reveal; with a solar drive no power cable is needed. Self-supporting blinds help where no rails can be fixed to the window frame.
What is a self-supporting blind?
A blind that works without guide rails directly on the window. It suits glass façades and buildings where drilling into the frame or façade is not wanted.
Are there blinds for sloping windows?
Yes, the Reflexa Asyflex. A telescopic rail follows the slope; windows with up to 45 degrees of incline can be shaded.
Does an external venetian blind darken the room?
Standard slats let some light through even when closed. For good darkening choose the blackout blind with Z or S slats.
How long does delivery take?
The delivery time is shown on each product, as every blind is made to your measurements.

This means you need not do without suitable sun protection even in difficult situations.
Sloped external venetian blinds
Indispensable for shading special shapes outdoors on high gable walls and conservatories.

If an Asyflex external venetian blind or an AsyRoll sloped roller shutter is no longer technically feasible, a Wendoflex blind is the answer. This special construction should be chosen whenever the particular building situation no longer allows convenient shading.
