1. Where are ScreenLine blinds produced?
Patented ScreenLine® system was firstly introduced to the world in 1992 by Italian concern Pellini SpA, a global leader in shading solution for insulating glass. Italian production plant in Codogno, near Milano, is the most up-to date production plant for shading systems in the world.
To fulfil constantly raising demand for ScreenLine products, Pellini S.p.A. extended its production capacity by setting up a new production facility in Hodonín, Czech Republic (2012). In a strategic position near Slovak and Austria border thousands of blinds per week are now being produced and delivered worldwide.
2. What does the product marking of your blinds mean?
Type of blind: SL22C
- SL = abbreviation for ScreenLine®
- 22 = width of the spacer bar (supplied by ScreenLine)
- C = type of control
- C = system controlled manually by two rotating magnets or by means of external motor attached to the glass).
- MB = system controlled by an internal brushless motor (motor is housed within the upper profile of the blind).
- P = Turning knob positioned on the window frame.
- W = system operated by internal brushless motor 3.6 Vdc, with an option of solar charging. Controlled by touch module situated on the glass or on the window frame.
- S = system operated by magnetic slider or by sliding magnetic handle
- B = system operated by knob located on the bottom of the glass.
SL22C = ScreenLine with spacer width of 22 mm and controlled by rotating magnets.
Note: "C" systems are standardly supplied with External magnetic device (EMD). It is also possible to choose from other available control options like Turning knob, Wand or External brushless motor 24V. These alternative controllers are fitted on the same position as standardly supplied EMD.
On what principle the ScreenLine integrated blinds work? How is secured the hermetic properties of the insulated glass?
Torque transmission is achieved through a patented system of two rotating magnets (see. Figure). One is outside the insulating glass (in the control device) and the second magnet is inside the IG unit (in the head rail of the blind) positioned concentrically with the first one. The blind is hermetically sealed between two sheets of glass. This system named ScreenLine® was firstly introduced to the world in 1992 by concern Pellini SpA, a world leader in shading elements for insulating glass. This maintenance-free, practical and aesthetical system is very popular among its users.

What are the size limits of ScreenLine® blinds?
- On the very type of a blind. Simply stated, robust solutions (e.g. the SL27C or SL27MB systems with 27mm spacers) allows greater dimensions of fully functional blind.
- For some systems (e.g. "C" or "S"), the thickness of the inner glass pane can affect the feasibility. Since the system is based on operation using magnetic force, it is necessary to know the thickness of the glass, through which the force will act. With an increased thickness of the glass, the force between the magnets and thus the full functionality of blind can be reduced.
It is possible to insert a ScreenLine® blind into an atypical shape of insulating glass?
What is the minimum overall thickness of insulating glass unit (double or triple) with integrated blind?
The overall depth of insulating glass with integrated blinds is not only depended on the width of the spacer bar, but also on the thickness of glass. ScreenLine® integrated blinds are supplied with spacers widths of 20, 22, 24, 27, 29 resp. 32 mm depending on the type of blinds*.
* The width of spacer bar can be easily recognized from each type of ScreenLine® blind, e.g. SL22C = ScreenLine® with spacer width of 22 mm.
Based on the frame and glass compositions (e.g. 2x 4mm) it can be calculated, that the minimum possible depth of double glazed unit with ScreenLine integrated blind is 28 mm * (with a tolerance of ± 2 mm). This applies for models with a 20mm spacer only (4mmGlass-20mmSpacers+4mmGlass).
The SL27C blind has a minimum depth of glazing 35 mm* (± 2 mm) = 4 mm (glass) + 27 mm (spacers) + 4 mm (glass).
For larger positions, it is necessary to use thicker glass, not only because of better statics, but also in order to avoid unwanted deflection.
The total depth of triple glazed unit depends on the thickness of the spacers in the second cavity and the thickness of the third glass pane.
What are the color options of your blinds. I noticed that you offer 9 color plates. What about drivers and other elements?
It depends on the type of blind. For example, for the "C" type we standardly supply a control devices of the same colour. For other types, e.g., "W" respectively. "S" there is a choice from three colours of controllers. We strive to ensure that all components are colour coordinated (profiles, slats, cords, control devices, etc.).
Based on the wishes and requirements of the customer, it is possible to combine colour of blind components.
Standardly supplied colours are part of the technical specifications for each product.
Is it possible to supply ScreenLine® blinds with black spacer bars?
- Spacers with 20mm, 22 mm and 29 mm width are supplied with white-gray (RAL 7035) warm-edge spacer as standard. On request, at no extra charge, black finish can be delivered (RAL9005) *.
- Other systems are supplied together with an extruded aluminum spacers with "NO-dust" surface finish. Available on request black aluminium spacer bar can be offered with an additional surcharge.
Does your products meet all certifications?
ScreenLine® products meet all certifications that are required by both national and European legislations. Since ScreenLine® products are supplied worldwide, they dispose of certifications which European legislation doesn´t require.
What can go wrong with your blinds? What is their lifespan?
During its production all ScreenLine® products undergoes a multi-stage quality control. A situation when installed blind is not working properly therefore appears in a small amount of cases (0.5-1 ‰ of total blinds produced).
When we inspect a blinds that is not working properly, in most cases, we find out that the blind was inappropriately tampered during transit to its destination, a misconduct occurred while inserting blind into the insulating glass, inappropriate glass configuration was used or when control components were not installed according to our instructions and manuals.
Through training and advice, we continually strive personnel who in their work performance comes into contact with our products, highlighting the need to follow our instructions for handling and installation.
ScreenLine® integrated blinds have all required certifications and have been subjected to many independent tests. Learn more at the website "Our quality".
Once the insulating glass unit with ScreenLine blind is installed in to the window frame and the blind is working properly, we can say that during its lifetime nothing should go wrong.
It is, of course, necessary to take into account the frequency of use. In general, all shading systems of all blinds producers should, in accordance with standards, have a minimum lifespan of 20,000 cycles (one cycle = complete raising and lowering). Our blinds go beyond this specified standard and are tested for a minimum of 40,000 cycles. Our blinds with an internal brushless motor, has recently been tested in IFT Rosenheim laboratory and has successfully reached a record of 200,000 cycles!
However, we recommend, especially when using automated systems for motor blinds, reduce the high frequency of raising and lowering cycles during the day. To extend the blind´s lifespan, automated systems should be programmed to regulate the passage of sun rays particularly by slats tilting.
Is it true that ScreenLine blinds dramatically reduce condensation on the inner glass pane of the window?
Yes, our integrated shading systems can significantly reduce the glass fogging from the interior. Unlike conventional blinds, where a cool air occurs between the glass and blind, the glass with integrated blind is constantly in contact with the warm air. This significantly reduced their dew.
Note. However, if the actual humidity in the room is high, the water will still condense in the coldest and badly ventilated part of the interior (e.g. on the peripheral wall behind the wardrobe, in corners etc.). We therefore recommend to keep the moisture in the interior around 50% at 20°C and preferably ventilate spasmodically. A moisture gets into the room during cooking, washing, showering but also by your breathing. It is known that the greatest condensation occurs in the room where we sleep (the air doesn´t move during the night and the interior / exterior temperature differences are at maximum at this time).
What impact has integrated blinds on the thermal properties (Ug values) of the glass?
In triple glazing unit blinds on the U-factor practically does not affect in any of its position.
In double glazing unit, the situation is as follows:
- blind fully raised: no effect on Ug value
- blind lowered with slats fully closed: improves the U-factor glass of about 0.1 W/m2K (it creates another cavity in the double glazed unit)
- blind lowered with slats fully open: worsens U-factor of about 0.4W/m2K (however, the slats must be completely horizontal. If they are tilt slightly, the deterioration disappears).
What are the advantages of integrated ScreenLine® blinds compared to conventional or external systems?
- for split windows, it´s possible to use only one large external blind
- a problematic use at high speed of wind which can damage the slats
- a need to clean the blind from time to time
- it can be an ideal hiding place for insects
- not suitable for sliding/bi-folding doors (the situation is even more aggravated in combination with mosquito nets)
- blind must be raised every time you want to walk in/out of the door
- blind is exposed to all weather conditions (some components can oxidize)
- complications with casings (problems with colder section of the peripheral wall)
- disturb view of the countryside (large and wide slats reduce the perception of the outside world)
- Design - closed slats can evoke industrial ventilation grille
- they will never get dirty (no need to ever clean them)
- free from risk of being damaged (ideal for families with children or pets)
- doesn´t cause a noise in the wind (do not resonate)
- they are an integral part of the door, doesn´t limit the passage through door
- an ideal solution for sliding/bi-folding/retractable doors and windows
- suitable solutions for both opening and fixed positions
- visually preferable solution where the fine slat (12,5 or 16 mm) is less noticeable in the glass
- blind is placed in a hermetically sealed cavity filled with an inert gas (argon) thus prevented from oxidation
- for each insulating glass unit one integrated blind is required
What does it mean "brushless" at motorized ScreenLine® blinds?
What are the requirements for the involvement of external and internal motors? How the blinds can be controlled?
- control units,
- power suppliers,
- remote control,
- magnetic contacts for openable positions (windows, sliding doors, etc.),
- ScreenTronic components compatible with KNX systems
How is the motor supplied by power in openable positions? I'd like to buy sliding doors together with ScreenLine blinds. What kind of preparation is needed?
- SL2187 two pairs of single-pole magnetic contacts
- SL2444 three pairs of single-pole magnetic contacts for connecting a data cable (white colour)
What electrical components are required to control ScreenLine integrated blinds SL22C equipped with external motor SL2190 to control 2, 3, 4 or more blinds at once? Is it possible to operate blinds remotely?
- ST1102 power supply for max. 2 blinds (we can also deliver power supply for 4 or 8 blinds).
- SL1807 control unit (up to 4 blinds). If you wish to control each blind separately, you will need SL1807 control unit for each blind.
- SL1963 control unit with radio receiver - if you require to control your blinds by remote control. This control unit can operate 1 blind only. Control units SL1807 and SL1963 can be linked together to meet the needs of more complex systems according to customer requirements.
- SL2392 remote control. The remote control can be linked (associated) with SL1963 control units, so that it will control each SL1963 or a group of SL1963 simultaneously. The remote control features 99 programmable channels.
