Product description
Blackout external venetian blinds, fitted with 90 mm wide S or Z slats, for darkening with guide rails or cable guidance – order in our shop.
As early as 30 years ago it was recognised that external venetian blinds can achieve a high blackout effect thanks to a special curvature of the slats, if they are shaped differently from a C-slat. The oldest blackout external venetian blinds are probably the Z-slats, which have a somewhat industrial, angular look. The S-slats are more harmonious and blend in more softly with the façade. Very high heat and light shielding.
Properties of S and Z slats as blackout slats:
- good darkening in the slat area
- good prices, made in the EU
- high wind stability thanks to the special curvature
- Somfy drives for motorised versions
- crank operation available
- angled pelmets available
- large choice of colours
- reasonable delivery times
- good workmanship and quality thanks to fully automated production
- no shipping abroad (German addresses only)
These colours are available.

Example calculation:
Cover plate height: e.g. for 90 mm S-slats, external venetian blind height with motor = 220 cm
= 220 mm plus 20 mm for the motor plus 20 mm recommended overlap = cover plate height 260 mm.
