Plastic windows in 100x250 with RC2 not possible?

Hello,

I have received feedback from my window installer that he believes my desired single-leaf floor-to-ceiling plastic frame windows in 100 cm width and 250 cm height with RC2 glazing are not feasible. The sash would be too heavy because of the laminated glass pane, and the fittings would not withstand it.

Does anyone have such a window with similar dimensions? Aluminum windows are not an option due to the price increase (they would probably work).
Are there special fittings for something like this? Or other solutions?

Best regards

I have had a patio door in my rental apartment for 12 years (the photo is old, the terrace was still under construction then), it is about 240-245 cm high and the sash is about 95 cm wide.


There is a glass-dividing bar and the fittings hold, but you can clearly feel when opening the door that this sash is taller than "normal".

I can understand the window maker. He has to stand behind the proper functioning for several years and physics usually can't be fooled. "Our" window specialist can certainly give you more details about that. And as always in life: You get what you paid for

Rrrüschdüsch. As a window guy, you live heavily off your good name. The customer can exempt me from warranty, but can I also trust that he won’t speak ill of me if the product obeys physics as I predicted? — no thanks, that’s not something you want.

I get the impression that some people here only read their own threads. And if I’m not mistaken, your case is not just about floor-to-ceiling alone, but specifically about floor-to-ceiling with flat threshold. So exactly the category of “stress element” that I’ve been preaching for five and a half years here should be made from aluminum.

If aluminum is not an option price-wise for one or a few windows, then the planning was wrong. Such a height dimension is, to put it kindly, “above standard,” it no longer exists even in PVC at discount prices, and then we’re already talking about a much smaller aluminum surcharge (about 20%). At that height, I wouldn’t take PVC at all, and even aluminum only with front door fittings / three instead of two hinges. The cheapest way, if you want to be stingy and still possible in PVC, would be the keyword “transom.”

By the way, I refer to my contribution in and also write again in the poetry album: flat threshold should only be planned in turn (not tilt-and-turn) – in post #210 of the linked thread, I illustrated my recommendation how I would “divide up” the elements in the concrete example of .

Hi,

thank you very much for the feedback.
All except one window are standard floor-to-ceiling. The window with the flat threshold is a terrace door with the same dimensions including RC2 and for some reason it was not considered problematic. Maybe it has to do with the fact that door hinges are used here, as you said.

I also did not receive the information that the dimensions are fundamentally the problem, but that the RC2 requirement makes the glass so heavy that it becomes an issue. Although normal RC2 glass is just a pane with laminated foil, does that really change the weight of the triple glazing that much?

The verbally mentioned surcharge for aluminum was more around +70%-80%, but was also named off the cuff.

If RC2 glass is really the problem with the window dimensions, then it only affects 2 windows. In the upper floor there are the same dimensions but without RC2.
Is installing door hinges a common measure or rather a hack?

Conversely, if there really is no problem with the terrace door, then I could ask if the two windows could be designed as terrace doors.
A flat threshold would not have to be there either if it helps with the issue. There are 2 deep windows with fall protection in the dining room.

I will inquire about the options.

Regards

Yes, I have a large staircase window where the lowest element, because it is directly in front of the stairs so that one could fall through, is VSG and the pane alone weighs 60kg. The others, higher up, with the same dimensions, only weigh 40kg.
