What is an external venetian blind?
An external venetian blind controls daylight very precisely. It is ideal for reducing heat, preserving privacy and keeping rooms pleasantly bright.
An external venetian blind uses adjustable slats outside the window. It blocks sun before it reaches the glass and lets you fine-tune daylight according to time of day and exposure.

Frequently asked questions
External venetian blind or roller shutter?
External venetian blinds are best for light control. Roller shutters are stronger for blackout, security and full closure.
Are raffstoren wind-resistant?
Resistance depends on model, guidance and exposure. An on-site assessment helps choose the right system.
