Configure your new Slope sloping blind for sun protection, privacy and heat protection in our shop and order with free shipping.
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.

The WendoFlex slat system from Reflexa® was developed to provide lasting shade even for the largest widths and heights in special shapes. Simply order it here in our shop Fitted with the sturdy 80 mm flanged slat, it allows very large widths. The following shapes are possible. Where AsyFlex and AsyRoll reach their technical limits, WendoFlex can often still be made. This means almost any shape can be shaded. With this design, however, the slats can only be tilted; they cannot be raised. You can configure the sloping quadrilaterals type W 5 in the shop. For all other special shapes, please send us exact dimensions and a photo of the installation situation, using the dimensions requested in the drawings. The dimensions always refer to the complete geometric shape (outer-edge dimensions) that is to be covered. For the available spacers, see configurator.
For inside: Dessiniso Slope
The Dessiniso Slope sloped blind has 25 mm aluminium slats and a 25 × 25 mm head rail. It hangs freely; at extra cost it is tensioned left and right with a plastic cord.
