ᐅ Prices excessively high for ventilation system and electric aluminum roller shutters (roller blinds).

Why blinds instead of Venetian blinds?

Venetian blinds usually cost extra compared to blinds. It was the same for us. Three electric Venetian blinds on windows measuring 2m x 120cm (6.5 ft x 4 ft), extra cost 3100 euros.
Controlled residential ventilation, also Zehnder with heat recovery ventilation (HRV), 11,200 euros for 135 sqm (1453 sq ft).
Lift-and-slide door extra 3500 euros, but we did not choose it either, see explanation @i_b_n_a_n
I cannot say about electric blinds, as they were included in our standard package.

Also, @11ant might also recommend (expensive) aluminum components in this area because it’s subject to high mechanical stress. Tilt-and-turn windows can be cheaper plastic elements.

That’s right. Aluminum costs about 20% more than PVC initially (list price). Discounts are available for PVC, but not for aluminum (profile, not covers). So, the actual price ratio is unfortunately more like 120:70 rather than 120:100. However, aluminum offers nearly three times the replacement interval. From a financial standpoint, aluminum is thus cheaper in the long run. But since most private builders think like consumers—and I am willing to learn—I recommend aluminum only for the high-stress and large elements here.

Note: I looked at lift-and-slide doors and was initially impressed (would have been 2.5m (8 feet 2 inches) wide). But everyone else advised against it and preferred a standard tilt-and-turn combination for the terrace door. And that was exactly the right decision. A hinged door can be opened more quickly and easily than a complex lift-and-slide unit.

In my opinion, that width is really the limit for even considering a lift-and-slide system. Generally, lift-and-slide doors are a definite “nice to have,” and I believe their high demand is mainly due to herd mentality. There is no more cumbersome linear movement than that of such a massive unit just to let the cat out. With a tilt-and-turn door, you can confidently “stick” with PVC here (and even consider upgrading the front door accordingly).

No roller shutters, only venetian blinds everywhere.

I’ll never understand this popular either/or mindset. But some people order a car with an electric motor and then skip the combustion engine—that’s just different, not better. Those who follow the majority should keep in mind that the majority is only average-smart (normal distribution applies).

I didn’t understand that (read it three times). Would you like to explain?
My presumed interpretation is: One should/may mix according to needs.

My interpretation is: You can/may mix depending on your needs.

How much longer I will continue explaining things here remains to be seen. Most likely, I won’t want to anymore soon (which is not because of the community—the problem lies at the top). P.S.: When I’m gone (the break two months ago was just a pause), I won’t come back!
Your interpretation is correct: In my opinion, the reasons for using venetian blinds do not argue against leaving out roller shutters. Both have their purpose and justification.

Maybe of interest to the original poster. I have had roller shutters in all my houses/apartments so far. But I was familiar with external venetian blinds (also called Venetian shutters or slatted blinds) from other apartments. I have never regretted choosing external venetian blinds for a second. They provide sun protection while still allowing daylight. Dark enough for me (otherwise there are Z-shaped slats). The only thing I regret is that I saved on everything in the bathroom. Now I only have one of those internally installed “zipscreens” added later.

For other rooms, I could imagine using roller blinds in bedrooms. But since the exterior appearance was also somewhat important to us, we would have mixed types on the north side. We didn’t want that.

P.S. @11ant We have been driving fully electric at the office since this week (3x Tesla Y, 1x MX30). Two of the Teslas are driven a lot (over 50,000 kilometers (31,000 miles) per year). Honestly, I can find no disadvantages to fully electric driving. It’s different AND better (although there are surely other opinions here ;-). I mention this because I interpreted from your last comment that you might be more a fan of hybrids (and think they combine the best of both worlds).

P.P.S. I also wouldn’t accept another forced break and agree with you 100% on that point.

That might also be a reasonable combination solution (?)

I haven’t had a forced break so far. My recent two-month forum hiatus was my own choice, even though the reasons were beyond my control. But if the helping hand is hit or bitten, then that’s the end of it.
