ᐅ Sun Protection for Penthouses – A Difficult Choice?

Hello dear forum members,
for our new penthouse apartment, a decision needs to be made regarding the installation of a sunshade.

1. Roller shutters /Advantages: additional thermal insulation, completely opaque, very wind-resistant /Disadvantages: light cannot be adjusted, looks like a garage door from the inside

2. Venetian blinds /Advantages: good light control, completely opaque, looks stylish /Disadvantages: difficult to clean, no thermal insulation, may rattle, wind and sun sensors needed

3. Fabric screen /Advantages: does not rattle, looks very modern, easy to clean /Disadvantages: light cannot be adjusted, permeability about 25%, wind and sun sensors needed, possibly not fully opaque???

We originally favored Venetian blinds with Z-shaped slats and a rail system, but due to the insufficient upper frame width, the raised package would protrude about 5cm (2 inches) into the glass pane.

With the fabric screen, this would not be the case; it would fit nicely inside the box, and the less attractive mounted rail system (as with Venetian blinds) would not be necessary either.
But now the most important question is: Is the fabric screen suitable as a privacy screen from the outside, or should it only be considered as shading? How does its durability compare to Venetian blinds or roller shutters? Replacing the fabric at some point would not be cheap either.

I would appreciate your advice.
Best regards, Frank

Hello, we have had the textile screens installed in our newly built house for 1.5 years. They are in anthracite color, provide excellent thermal insulation, and offer very good daytime privacy—you cannot see inside from the outside, but you can see out from the inside. When it gets dark and the interior lights are on, some visibility from outside is possible.
