For these products, CAD drawings and a factory confirmation requiring counter-confirmation are always prepared.

You must then check and countersign this.

You will then receive an invoice with your chosen payment method. The special shading then goes into production.

Info and measuring guide

- horizontal base width = order width of the blind (geometric shape)

- high height = order height

- small height = small order height

The manufacturing dimensions are derived from these measurements.

When mounting IN FRONT OF a reveal opening (on an open house wall), please take into account the necessary overlaps all round and the stack dimensions. All order dimensions are finished dimensions of the geometric shape.

Please note:

If you make deductions yourself for reveal mounting, please bear in mind that this also changes the diagonal of the geometric shape. This in turn changes the height dimensions correspondingly, by more or less. If you deduct from the base width, a new geometric shape leading vertically upwards must therefore be measured, which does not correspond to the net dimensions of the actual reveal.

How to measure

Measuring guide for the sloping external venetian blind fitted in the reveal:

- Reveal depth at least 14 cm for 80 mm slats.

- horizontal base width (outer dimension of the geometric shape, i.e. outer edge of guide rail to outer edge of guide rail) = order width of the blind

- tall height = order height (top edge of head rail to bottom edge of bottom rail)

- short height = short order height (top edge of head rail to bottom edge of bottom rail)

Measuring instructions for installation in the reveal:

- reveal depth at least 14 cm for 80 mm slats and 10.5 cm for 50 mm slats.

- horizontal base width (slat width or outer edge of guide rail to outer edge of guide rail) = order width of the blind

- tall height = order height (top edge of head rail to bottom edge of bottom rail)

- small height = small order height (top edge of head rail to bottom edge of bottom rail)

- slope of the blind at the top = order dimension of slope S (check dimension only)

The manufacturing dimensions are derived from these measurements. The deductions are made at the factory.

For installation IN FRONT OF a reveal opening (on an open house wall), please take into account the required overlaps all round and the stack dimensions in height. All order dimensions are finished dimensions of the blind.

Measuring summary:

- for recess installation, please state the clear recess dimensions (deductions are made at the factory)

- for installation on an open façade, please state the finished dimensions of the blind, i.e. clear recess dimensions plus side overlaps and top stack overlaps.

- horizontal base width = order width of the blind

- tall height = order height

- short height = short order height

- slope of the blind at the top = order dimension of slope S

These dimensions give the manufacturing dimensions.

For installation IN FRONT OF a reveal opening (on an open house wall), please take into account the necessary overlaps all round and the stack dimensions. All order dimensions are finished blind dimensions.

Please note:

If you make deductions yourself for installation in the reveal, please note that this also changes the diagonal of the geometric shape. This in turn changes the heights accordingly, by more or less. If you deduct from the base width, a new geometric shape running vertically upwards must therefore be measured, which does not correspond to the net dimensions of the actual reveal.

Product description

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.
