FAQ

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 blindSL22C

  • SL  = abbreviation for ScreenLine®
  • 22   = width of the spacer bar (supplied by ScreenLine)
  • C    = type of control
  1. C = system controlled manually by two rotating magnets or by means of external motor attached to the glass).
  2. MB = system controlled by an internal brushless motor (motor is housed within the upper profile of the blind).
  3. = Turning knob positioned on the window frame.
  4. 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.
  5. S = system operated by magnetic slider or by sliding magnetic handle
  6. 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.

Where can I see and try your products? Do you have your own Showroom?

Samples of our products can be viewed and tried at selected dealers and window producers. For more information you can contact us or register on our website to receive updated information.
 
Every year Pellini SpA participates in several fairs. A wide range of ScreenLine® products can be seen at trade fairs in Nuremberg (Fensterbau Frontale), Düsseldorf (Glasstec), Paris (Batimat), Milan (MADE), and many other places around the world. We will inform you in our section News - Events about all trade fairs, we will be present with our ScreenLine® range.
 
             

What is the price of ScreenLine® blinds?

The price of our blinds can not be determined in square meters because each blind consists of a complicated control mechanism and relatively cheap slats. Therefore price of 2m2 is not twice the price of 1m2. It is necessary to know the exact dimensions of each glass. To request a quote, please contact your window producer or dealer. If your selected window supplier doesn´t offer ScreenLine products, you can contact us. Per return we will send you a list of ScreenLine suppliers in your area.
 
Note: The ScreenLine® integrated blinds can become part of most types of manufactured windows (PVC, AL or wooden). Our assortment of blinds are inserted into insulating double and triple glass units. ScreenLine® blinds become an integral part of the glass unit, not the window. Our blinds have a lifespan beyond the lifetime of the window. They are maintenance-free and cannot be destroyed or damaged. Their production is extremely difficult and must meet very strict requirements.
 
Unlike conventional blinds, integrated blinds in addition regulate light and heat passing through glass (g value = 12%, under certain circumstances up to 7%!), Thus completely capable to replace exterior blinds. This brings huge savings in air conditioning, well being and thermal comfort, which can not be achieved by conventional blinds. Saving in air conditioning can, on the south side of buildings, gain about €7 / m2 of glass per year. Acquisition of ScreenLine integrated blinds is an investment with a quick return. It is up to each customer's assessment what functions from their windows they expect.

What is the warranty period for the range of ScreenLine® products?

Pellini S.p.A. guarantees all ScreenLine® products against any possible manufacturing defect, provided they are properly assembled into the sealed glass unit (during glazing), and into the window frame (during IGU installation), in compliance with the instruction manual and the indications for a correct assembly, both supplied by Pellini S.p.A.. 
Guarantee will apply, starting from delivery date of products (as per delivery note): 
  • for a five-year period in standard conditions of use, as regards all components integrated into the sealed glass unit and
  • for a two-year period in standard conditions of use, as regards all components located outside the sealed glass unit.

What are the size limits of ScreenLine® blinds?

Size limits of ScreenLine® blinds are listed on our website separately for each type of blind. It is possible to insert two blinds in one insulating glass and thus increase/double the size limits. It depends on the type of blinds and on each specific customer´s requirements and expectations - blind with full functionality, ie. raising and lowering or with tilt only function. 
Size limits can depends on several factors:
  1. 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.
  2. 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?

ScreenLine® blinds are mainly inserted into rectangular or square formats of insulating glass. Manufacturability of atypical shapes of blinds must therefore be consulted.

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.

 
Colour coordination of "C" type:
 
Colour options of magnetic slider for "S" sytem (Venetian):
 
 
 
 
Colour options of "W" system:
 

 

Is it possible to supply ScreenLine® blinds with black spacer bars?

ScreenLine® blinds are supplied together with an aluminum or "Warm-edge" spacer bars (depended on type).
  • 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.
* In case of fire-resistance requirement, ScreenLine 20mm and 22 mm systems can be supplied together with an aluminum spacer (also in black finish). Please, contact us for more details.

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?

Influence of the integrated blind on the U-factor of the glass differs depending on whether it is inserted into a triple or double glazing.

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).
In practical terms, it is important to remember that the largest temperature differences (interior/exterior) are during night, when integrated blind is lowered and closed. This helps to reduce the Ug value thus saving heating costs.
The influence of pleated blinds and rollers are only positive as they form another chamber in the glass. For example, the roller can achieve a U-factor of 0.8 W/m2K (normally 1.2 W/m2K) in double glazed unit (IFT Rosenheim certification here).

What are the advantages of integrated ScreenLine® blinds compared to conventional or external systems?

ScreenLine® integrated blinds can be, regarding its functions, compared only with external blinds. Only those, like integrated blinds, can control the solar radiation (perceived as heat passing into the interior). Interior blinds only shield the visible light and provides some privacy. Its function is limited and at certain time of the year is rather negative (in winter they help the condensation on the inner pane of the glass and in the summer they act as a radiator).
 
For this reason, we can compare the advantages and disadvantages of only external and integrated blinds:
 
EXTERNAL BLINDS:
 
Benefits
  • for split windows, it´s possible to use only one large external blind
Drawbacks
  • 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
ScreenLine® INTEGRATED BLINDS:
 
Benefits
  • 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
Drawbacks
  • for each insulating glass unit one integrated blind is required

What does it mean "brushless" at motorized ScreenLine® blinds?

ScreenLine® systems with internal and external motors as standard feature new, sophisticated brushless technology. The brushless electric motor does not consist of comutator with mechanically consumable brushes made of grafite (coals). The movement of the rotor is effected through precisely timed electromagnetical pulses.
 
 
Brushless motors are very quiet and their lifespan is multipled compared to the older version. Successful tests in IFT Rosenheim laboratory exceed 200,000 full cycles (ten times the norm).
 
Integrated blinds with brushless internal motor "MB" in addition allows a feedback - which means they can provide the user with information on which position the blinds are currently located, information on the actual slats´ angle, a number of cycles, etc. The system is also possible to modify by means of software upgrade.

What are the requirements for the involvement of external and internal motors? How the blinds can be controlled?

ScreenLine® motorized blinds are powered by 24Vdc (or. 3.6Vdc for battery-powered motors) and the lowering and raising movement is carried out by changing of the polarity (polarity inversion). Motorized blinds can be supplied together with electrical components which are necessary for their operation. This includes:
  • control units,
  • power suppliers,
  • remote control,
  • magnetic contacts for openable positions (windows, sliding doors, etc.),
  • ScreenTronic components compatible with KNX systems
  • etc.
At the same time, we can design customized connections and control solutions according to client requirements. Our blinds can become a part of smart home systems (BMS = Building Management Systems, BAS = Building Automation Systems, etc.).
Recently, we consulted with our client the possibility to control ScreenLine® blinds using commercially available applications for smart phones and iPhones. If you require "made-to-measure" solutions, please contact us.
 
           

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?

ScreenLine® blinds are an ideal shading solution for sliding or bi-folding doors, where the use of conventional or external blinds would be inappropriate or even impossible.
 
Transmission of electric power needed to supply blinds´ motors in openable doors or windows is made possible through our patented magnetic contacts. They are placed in the frame and in the casement (door or window). When the position is open the contacts open too which stops the power supply to the motor. When the position closes, the magnetic contacts connect again. If the window gets open during the process of raising or lowering, the blind stops. After the magnetic contact connect again the motor wait for the new impulse, or will continue with the last order.
 
 
Regarding preparations; each window must have two-wire / three-wire cable terminated in the window / door frame. A cable that is a part of the blind, and comes out from the insulating glass needs to be terminated in the casement opposite the wires led from the frame. It is necessary to determine in advance the best location for the magnetic contacts. They will operate at a maximum distance of 6 mm. Learn more after the registration in our manuals and instructions section on "Downloads" bookmark.
 
                        
 
There are two types of magnetic contacts available:
  • SL2187 two pairs of single-pole magnetic contacts
  • SL2444 three pairs of single-pole magnetic contacts for connecting a data cable (white colour)
The package includes magnetic contacts for one opening window / door (2 pairs or 3 pairs of magnetic contacts) and spacers for eventual adjustment of the distance between contacts.
 

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?

To control an external motor SL2190 (applies also to systems with internal motor) following components are required:
  • 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.
Example: If you have 10 motorized blinds controlled (with internal or external motor), and you want to manage them remotely one by one, then each blind must have its own control unit SL1963. You can then associate the channel no. 1 on the remote control unit to the SL1963 of the first blind, second channel with the second unit, the third channel with the third and so on. But, at the same time you can also associate the channel No.11 to control units 1, 3, 6, and channel No.12 to control units no. 4, 8 and 10. You have 99 channels, thus 99 control options. The master channel "00" controls all the associated control units together. Each control unit can store up to 64 commands from one or multiple remotes SL2392.
Examples of connections and a procedure for associating individual control units with a remote control are available on our website in the "download" section.
It depends on customer requirements how he would like to control ScreenLine blinds. We can design control systems according to anyone´s needs.
Note: For opening / sliding doors or windows we have a unique system to transfer power from the window frame to the casement (motor) - ie. Magnetic contacts.
