What is a sun louvre shutter and how does it work?
A sun louvre shutter is a movable external system that stops the sun outside the glass while adjusting light and air with its slats. This guide explains the two ways they work, six models led by Tiktak Orient, and which one to choose when.
What is a sun louvre shutter?
A sun louvre shutter is a roller shutter system with movable aluminium slats, installed outside the window or façade. A classic roller shutter is either closed or open; with a sun louvre shutter you change the angle or the gap of the slats to set light, air and view. Because solar heat is stopped outside the glass, the interior stays cool and the cooling load drops. Ferrini's sun louvre shutter family has six models.
Two ways of working
Sun louvre shutters fall into two groups, depending on how the slats open:
- Tilting-slat systems — the slats rotate on their own axis; the angle directs the light and shows the outside without giving up privacy. The venetian shutter, Tiktak Orient and the external venetian blind belong here.
- Parting-slat systems — the slats do not rotate; gaps open between them and light and air come in as thin strips. Tiktak Daylight, Airlight Mini 16 and Airlight 30 belong here.
All six models give blackout when fully lowered and closed; they are operated by motor, remote control or smart home system and are made in all RAL colours.
Tiktak Orient: slats that open to 60 degrees
Tiktak Orient is our tilting-slat sun louvre shutter, also searched for as "Orient sun louvre" or "Orient shutter". Closed, it covers the façade like a classic roller shutter; raised one notch, its movable slats open up to 60 degrees and let light and air in between them. Single units go up to 3300 × 3300 mm and 9.9 m², installed with a front-mounted or built-in (concealed) box. It can also be fitted to an existing box if the winding diameter fits.
The other models
- Venetian shutter — slats tilt in 21 steps up to 110°; a roller shutter and a venetian blind in one system. Installed with a built-in box.
- Tiktak Daylight — 50 mm slats part by 10 or 20 mm and let light in as thin strips.
- Tiktak Airlight Mini 16 — its 16 mm slat gives the smallest winding diameter, suiting narrow boxes and minimal façades.
- Tiktak Airlight 30 — 30 mm double-wall slats and 50 mm ventilation slots, spanning up to 4 metres.
- External venetian blind — works outside the façade in its own box, carried on stainless steel cables; tilts separately at every height and reaches 18 m² in one piece.

| Tiktak Airlight 30 | 50 mm ventilation slot | 4000 × 3000 mm (recommended) | Monoblock, surface-mounted, built-in |
| External venetian blind | Tilts separately at every height | 6000 × 4000 mm, 18 m² | Its own box (ceiling- or wall-mounted) |
Which one should I choose?
- To see out while keeping privacy, choose a tilting-slat model: Tiktak Orient if there is a front-mounted box, the venetian shutter in a new building.
- To manage the light most finely, the venetian shutter with 21 steps.
- If the box space is narrow, Airlight Mini 16 with the smallest winding diameter.
- For wide openings and plenty of ventilation, Airlight 30; for large façades and offices, the external venetian blind.

Frequently asked questions
Are the Orient shutter and Tiktak Orient the same product?
Yes. Tiktak is the name of our sun louvre shutter series made up of the Orient, Daylight and Airlight models; Orient is the model in this series whose slats tilt up to 60 degrees. It is also searched for as "Orient shutter" or "Orient sun louvre".
Does a sun louvre shutter give blackout?
Yes. All six models darken the room like a classic roller shutter when fully lowered with the slats closed.
Can a sun louvre shutter be fitted to an existing shutter box?
It depends on the model and the box. Tiktak Orient and Daylight fit front-mounted and built-in boxes, the Airlight models also monoblock boxes; the venetian shutter works only with a built-in box. Our authorised dealer checks during the survey whether the winding diameter fits the box.
Is a sun louvre shutter motorised?
Yes. It runs on a tubular motor and is operated by remote control, wall switch or smart home system.
Measurement and quote
Our sun louvre shutters are made to measure at our İzmir facilities and shipped to our authorised dealers as knock-down systems; your nearest Ferrini dealer takes the measurements and installs them.
