Measurement for the order width (exterior) when installing with spacers on the window frame.

- Measure the narrowest dimension from wall to inner wall edge minus 1 cm = order width. The guide rails are screwed to the window frame using spacers. Installation in the window opening.

Measurement for the order height (exterior)

From the underside of the window opening (also called reveal or lintel) to the top edge of the window sill, minus 5 millimetres = order height

--------------------------------------------------------------------------------

Alternative installation type:

Measurement for the order width (exterior) when installing without spacers in the wall opening.

- Measure the narrowest dimension from wall to inner wall edge without deduction = order width. Here the guide rails are simply screwed through the guide towards the side wall. Installation in the window opening.

Measurement for the order height (exterior)

From the underside of the window opening to the top edge of the window sill, minus 5 millimetres = order height

--------------------------------------------------------------------------------

Alternative installation type:

Measurement for the order width (exterior) when installing with spacers in front of the window opening.

- Window opening plus approx. 5 cm overlap on the right and left = order width

Installation on the wall, so that the blind package is not in the window's field of view when raised. Side caps are required for the cover plate, see order form.

Measurement for the order height (exterior)

- Window opening plus package height = order height

Slat and guide
Info and measuring guide

Please select the slat width here.

With flat slats, the slat stack in the raised position is reduced by approx. 25 %.

Explanation:

- flanged slats are bent over at the sides = flanged, which makes them very stable but gives slightly higher stack heights

- flat slats are made of the same material in the same thickness, but are more sensitive to storms at larger widths. Because of their flat shape, the stack heights are smaller

We recommend rail guidance for every blind, as this version is very resistant to storms.

Type
Info and measuring guide

Here you can order double guides (double guide rails or double cable tensioners, depending on the blind version) at no surcharge.

Type

If you want to mount several blinds side by side on a house front, each with its own drive but connected at the ends with a double guide, select coupled blind in the selection; you will receive 1 x single guide (for the side guidance) and 1 x double guide in which the units are to meet. The measuring is the same. Width as always = outer edge of guide rail to outer edge of guide rail, which for a double guide rail would be the centre point of the double guide rail.

With cable guidance = outer edge of slat to outer edge of slat.

For 3 units which are to run together side by side, proceed in exactly the same way. Then please select centre-coupled blind for one blind. For 3 blinds, for example, you will then receive 2 x single guides and 2 double guides.

We have discontinued the option of ordering coupled blinds with only one drive and 2 blinds. The reason is that the tapes in the blinds are subject to differing shrinkage. This means that with 1 drive and 2 blinds, the units hang crooked over time. Subsequent adjustment/equalisation of the heights is not possible with coupled units with only one drive.

We therefore only offer coupled units each with their own drive.

Additional cable guide
Info and measuring guide

This is recommended for blind widths of 3 metres or more.

An additional hole is punched in the slats and a plastic-coated steel cable is threaded through. An angle bracket in a matching colour is supplied for tensioning the cable.

For asymmetrical additional tensioning, please enter the dimension under “Notes”. Please also state from which side you measured. (left or right, as seen from inside or outside)

Fitting type
Info and measuring guide

Ceiling installation = installation in the reveal towards the ceiling or under a roof overhang.

--------------------

Wall installation: installation in front of the reveal opening towards the wall (brackets are supplied)

Operating side
Gear type
Info and measuring guide

We distinguish between two gear settings:

- FLUSH gear means that the overall order width of the blind is also the delivered width of the blind. The crank gear is therefore mounted on the head so that it is exactly flush on the outside and does not protrude at the side.

- PROJECTING gear means that the gear at the top of the head protrudes 2.5 cm beyond the actual order width. This variant is ordered if the crank gear feed-through is to be offset sideways in the masonry. See picture below = projecting gear.

Please note that we can also manufacture gear projections to your wishes and dimensions. If required, please talk to us or enter your wishes under “Notes”.

Info and measuring guide

The bottom rail, spacers and guide rails (with cable guidance, this applies to the tensioning brackets at the bottom) are manufactured in this colour.

The head is always natural silver RAL 9006. Please enquire about special requests.

Extras
Info and measuring guide

- 38 degree working position:

When the venetian blind is lowered, the working position engages automatically and tilts the slats to a 38 degree opening angle. This angle ensures optimum sun and glare protection and meets the requirements of the German Workplaces Ordinance. The working position is held in any stopping position of the blind and can also be deactivated in any position.

- Daylight-guiding technology: (one third of the blind height)

The principle is that the slats in the upper section are tilted differently from those in the lower section. This allows you to regulate the incoming daylight yourself as required.

Spacer
Info and measuring guide
Spacer

If you do not select any spacers, we will supply the standard size.

Info and measuring guide

We can supply L-shaped fascias or U-channel fascias (square-edged).

If you order aluminium angle fascia "YES", we always supply the fascia 1 cm wider than the blind width.

If you need a different fascia width, please enter this under “Notes” or call us on 09732 3023858.

We can supply L-shaped fascias or U-channel fascias (square-edged).

High-quality coating, in a 2 mm thick version.

If you order aluminium cover fascia "YES", we always supply the fascia 1 cm wider than the blind width.

If you require a different fascia width, please enter this under “Notes” or ask us by phone on 09732 3023858.

- please enter the width here in the format

for example: 212.5 cm

For installation in the reveal, the trim should be as wide as the reveal minus 0.5 cm.

For installation in front of the reveal opening, the trim should be 1 cm wider than the blind dimension.

For installation in front of a conservatory or around a corner, a wider trim is usually required. You can choose and enter the dimension freely.

The developed height is always adapted to the blind height.

The colour of the cover trim is always the same as that of the side rails and bottom rail of the blind.

The manufacturer is REFLEXA-Rettenbach.

The height of the cover trims is automatically adapted to the stack heights. We supply the trims in L shape.

Other trims, e.g. in U shape, are available for a surcharge.

If you need wider cover trims (e.g. for coupling on a conservatory etc.), please enter the exact width under “Notes”.

Aluminium angled pelmet

These are required if two plates are to be joined so that a window front is covered uniformly by the cover plate.

For example, you have 2 blinds on a façade that are to be installed next to each other. However, the plate is to be continuous. You therefore order 2 plates with only one side cap each and a butt connector in the middle. The two plates then usually have to be wider than the blind. Please enter the exact width under “Notes”.

Aluminium angled pelmet Aluminium angled pelmet

As standard fascias, we supply fascias in L or U shape for mounting on a wall, ceiling or reveal. The lower flange is bent inwards. (edge protection, see fascia types 2 above)

-----------------------------------------------------------------------------

Alternatively, at no surcharge, we can offer the following fascias as plaster carriers type 2.1 and 5.1 for integration into a façade that is still to be insulated. In this version, the lower flange is bent outwards so that it can be used as a plaster edge. The bent dimension P 1 is 2 cm. These fascias are also available as L or U trims. Plaster carrier fascias are always supplied in natural silver, uncoated. When using plaster carrier fascias, please note that thermal reactions may occur due to the different material properties of the aluminium fascias and the plaster carrier boards. Please always consult your architect about this.

Aluminium angled pelmet Aluminium angled pelmet
Side cap
Info and measuring guide

These are required if you want to install in front of a reveal opening, in order to close off the cover plate at the sides. (riveted firmly to any angle plate at the factory)

Product description

Made-to-measure external venetian blinds with crank operation, all made in Germany. Many slat widths and versions available. Maximum size 500 cm wide by 400 cm high. Simply order in our shop.

This high-quality design (original Reflexa® external venetian blinds) allows large widths and heights at the same time and is also largely unaffected by wind and storms. (Slat thickness 0.50 mm = more than twice as thick as a standard 50 mm slat.) All mounting brackets, consoles and any stiffening brackets for the cover panels are included free of charge with every delivery. Our external venetian blinds come as standard with a 180-degree tilting mechanism. A 38-degree working position or light-directing technology is available as an option, both controlled via the crank.

Good reasons to choose Reflexa external venetian blinds with crank operation:

- high-quality, precise workmanship, smallest possible stack heights for all slat types

- wide colour range, well-proven system (all beaded slats with deep punching, no PVC eyelet)

- 80 mm flat slats also available with rail guide, so the smallest possible stack heights can be achieved

- many slat widths to choose from, C 60 mm and C 80 mm available

- 60 and 80 mm flat slats available with cable or rail guide

- safe delivery by our own factory lorry within Germany, by freight forwarder throughout the EU plus Switzerland

- minimum width with cable guide = 33 cm, minimum width with rail guide = 40 cm

- Please note*: with small widths, the slat curtain may run slightly out of true; this cannot be avoided.

Our Reflexa external venetian blinds are fully pre-assembled at the factory and are therefore easy to fit yourself. Detailed, professional fitting instructions are also included. Should you still have any questions about fitting or before measuring, our hotline will be happy to help.

The external venetian blinds are operated by crank, the most economical version. (Crank outlet 45 degrees.) The hexagonal crank rod (wall feed-through) on the joint plate is 30 cm long and is cut to length during fitting. If you need a longer rod, please ask us separately or enter it in the "Special requests" field.

Please note: All order sizes are finished sizes of the blind. Outer edge of guide rail to outer edge of guide rail = order width, and top edge of blind to bottom edge of bottom rail = order height of the finished blind.

The guide rails are screwed to the window frame using spacers = fitting in the window reveal.

Measuring the order height (external)

From the underside of the window opening (also called the reveal or lintel) to the top of the window sill minus 5 millimetres = order height of the external venetian blind

Alternative fitting method

Measuring the order width (external), when fitted without spacers in the wall opening:

- Measure the narrowest dimension from wall to inner wall edge without any deduction = order width of the external venetian blind. Here the guide rails are simply screwed through the guide towards the side wall = fitting in the window reveal.

Measuring the order height (external): from the underside of the window opening to the top of the window sill, minus 5 millimetres = order height of the external venetian blind

Alternative fitting method.

Measuring the order width (external), when fitted with spacers in front of the window opening:

- Window opening plus approx. 5 cm overlap on each side = order width of the external venetian blind

In this case the blind is fitted on the wall so that the raised slat stack is out of the window's field of view. Side caps for the cover panel are required, see configuration.

Measuring the order height (external)

- Window opening plus stack height plus 3 cm = order height of the external venetian blind

Fitting options: ceiling, wall, recess

Crank gear with 45-degree outlet as standard. 90 degrees possible.

Picture shows standard guide rail size = 25 x 25 mm

We are happy to send you the stack heights and specifications of the individual slat types on request.

Please note: The cover panel is 2.5 cm higher than the respective stack height.

The following slat colours are available. Bottom rail, guide rails and spacers come as standard in white RAL 9016, cream white RAL 9010, silver RAL 9006, RAL 9007, DB 703 or anthracite RAL 7016 and RAL 7015 at no extra charge. Rails, spacers and bottom rail can be coated in a different RAL colour at no extra charge. The head rail is always natural silver RAL 9006 and is normally concealed by the optional cover panel.


Also available in RAL 7015 slate grey and RAL 7037 dust grey. Other colours on request.
