A slat turns to any angle — so you meter the light without losing the view from the window. The blinds SkyFlow sit outside, so the heat never reaches the glazing. Six families: a headbox above the window, concealed installation under render or within the insulation layer, and the interior C50 SLIM. Electric drive, sun and wind sensors, smart home. If you need fabric instead of slats, those are facade screens.
Click “Calculate” on a card — the system will be filled into the quote form.
The headbox is built into the insulation layer or under the render — only the slats and the guides stay visible on the facade. The inspection hatch opens from outside, so servicing never means dismantling the facade.
The same concealed installation in a simpler headbox. A version with a painted headbox is available — for when part of the box does stay visible and has to match the facade colour.
The largest area in a single curtain: one unit covers up to 18 m². The C 80 slat rotates through 0–180°, the Z 90 through 0–90°.
Fitted to a finished facade with no rebuilding: the headbox is surface-mounted and covered from above with a colour-matched aluminium panel. C 50, C 80 and Z 90 slats.
A self-supporting structure with a CUBE (rectangular) or OVAL cassette and side guides — the solution for renovations and large openings.
Facade aesthetics inside the room: the narrow C 50 Slim slat and cable guides. A manually operated version is available — the most affordable in the range.
The images are manufacturer renders by Aluprof. Below are all 18 price-list systems with “from” prices, followed by the calculator and the full list of surcharges.
Maximum sizes come from the Aluprof technical data sheets. “Wide and tall at the same time” is not always possible: the calculator below checks every cell of the price list and tells you if a size falls outside the grid. “From” is the lowest price for the system including VAT at 21 %, excluding delivery and installation.

The system images are manufacturer renders by Aluprof; photographs of our own installations are in the gallery below. Versions marked “manual operation” cost less than the electric ones: instead of a motor there is a crank handle two thirds of the system height (the C50 Slim uses a 2 m cord). No power supply has to be run to the window.
System, window dimensions, motor and controls — the price is calculated immediately from the manufacturer's 2026 price list including VAT. We will confirm the exact amount with installation after the measuring visit.
Give us the dimensions and the system — we will check them against the technical data sheets and send you an exact price the same day.
We calculate the whole set: system, drive, guide rails, sensors and installation.
Everything the Aluprof 2026 price list charges on top of the system price (pp. 29–56). Prices include VAT at 21 %. The calculator above adds these items up for you — here is the full list, so nothing in the quote comes as a surprise.
The price of every electric system already includes a motor with mechanical limit switches — Elero JA Soft 6 / 9 Nm, JA DK 10 / 20 Nm for large curtains or Geiger GJ56. Electronic limit switches (JA Comfort, J4WT), built-in radio (JA Comfort 868, Somfy io), ice and obstacle protection (Protect) and the SMI bus for smart homes are surcharges as listed in the table. The motor class (6 / 9 / 10 / 18–20 Nm) depends on the area and weight of the curtain — we allow 6 Nm up to 4 m² and 9 Nm above that, and confirm the exact class from the technical data sheet. Slat rotation: C 80 and Z 90 turn through 90° as standard, and 180° rotation is available for C 80 (specify when ordering); C50L and C50 Slim turn through 180°.
The INIS wired switch is for motors with wired control. Radio: Somfy Situo remotes (in the Var — version, with slat angle adjustment), the five-channel Situo 5 with a sun sensor, TaHoma Switch for your smartphone and the Sunis sun and Eolis wind sensors — all for io motors. For electronic limit switches the installer needs a setting cable — 146.41 €.

Colour outside the standard palette — a structure colour outside the standard palette: 300 € per order (1–4 systems), 400 € (5–9), 500 € (10–20), from 21 systems there is no surcharge. Delivery — Delivery is 200 € per order (not per unit); free of charge if the order waits for a full load to be assembled — the lead time is then longer. Lead time — lead time 2–3 weeks, BOX around 4 weeks. The cassette (headbox / panel) height in cm follows the window height; the total system height = window + cassette.
Every colour below is included in the system price (SELT 2026 price list, pp. 30–31). On-screen shades are approximate — we confirm them against the RAL catalogue and a sample at the survey.
Z 90 and C 80 slats — 19 colours included in the price (standard gloss 30 %, VSR 780 — 60 %); C50L — 4 colours; C50 Slim — 8 colours. Other slat colours on individual request. The on-screen shade is approximate. 31 structure colours (headbox, guides, panels) are included, and two further textured finishes — RAL 9010 STR and RAL 8003 STR — carry a surcharge on request. Any other RAL is 300 / 400 / 500 € per order (1–4 / 5–9 / 10–20 systems), with no surcharge from 21 systems. Lead time: 2–3 weeks, BOX around 4 weeks.
The heat is stopped outside, before the glazing unit — the room does not overheat.
Tilt to any angle: the light is metered and you keep the view from the window.

The sun is stopped right up to the glass: the heat never enters the room at all, instead of being fought off by a blind on the inside. In summer that means a few degrees less indoors and savings on air conditioning.
To 4.5 m wide and 4 m high — the limit depends on the system and the curtain area; the exact limits for all 18 systems are listed above under “All 18 price-list systems”.
Concealed installation under plaster, within the insulation layer, surface-mounted or interior (C50 SLIM) — the solution can be planned into a new build as well as an existing house. Controls — electric drive, remote control, smart home, sun and wind sensors.
Price based on the project: system, dimensions, automation. Send us your window dimensions or the facade drawings — we will calculate the price and come out for a professional measuring visit (throughout Latvia and the Baltics, we also work across Europe). 2-year warranty.
Send us a photo of the facade and tell us which way it faces — we will say which family suits and price up the set.
