Hello,

we are currently quite unsure about the fall protection for our floor-to-ceiling windows. Originally, windows with built-in separation and fixed glazing at the sill height were planned. However, my wife recently became enthusiastic about a modern French balcony.

The enthusiasm cooled down noticeably once we saw the high price of the stainless steel railings. Now we are facing a dilemma.

What are the advantages and disadvantages of the two options?

What would be the approximate additional cost for the lower fixed glazing compared to the French balcony?

Same here, why should it be different. The heat should definitely stay outside.

Thanks to the controlled ventilation system with heat recovery—and specifically the reversible heat exchanger (not all controlled ventilation systems have this)—we definitely do not open the windows during the height of summer.

We do the same during the day, even with cooling provided by underfloor heating and an air-to-water heat pump. However, at night it is usually cooler outside than inside, so opening a window does make sense. A controlled ventilation system does not provide any significant cooling effect.

That's correct. But at night, the sun doesn't shine, which was mentioned here as a problem because of the blinds on fixed elements.

That’s true. But the sun doesn’t shine at night, which was mentioned here as an issue concerning shutters on fixed windows.

However, some people might not want to be woken up by light at 4:30 a.m., whether from street lighting or other sources. But as mentioned, it depends on how sensitive someone is to light.

Then use window grilles and only open the blinds at night just enough so the light doesn’t disturb. Or cool the heat away with the heat pump and keep the windows closed.

I recently spoke with a window manufacturer. According to DIN 18008 (VSG(P4)), they estimate additional costs of about 105 euros per square meter of glass.

Whether this is a reliable figure will only be clear once the official quote is received. Unfortunately, none of our friends have floor-to-ceiling windows with a lintel-safe lower pane.
