Hello everyone.

Yesterday afternoon, we had a conversation with our window installer, who was commissioned by the general contractor.

It concerns a gallery window with a rough opening size of 201cm (79 inches) width and 213.5cm (84 inches) height.

The window is fixed glazing.

He claims that he cannot supply the window as a single piece, but only in two parts.

He justified this by referring to a standard, stating that a window can only be deflected by 8mm (0.3 inches) if wind pressure is applied, and so on.

Is this all correct? Or does he simply not want to install such a large (and possibly heavy) window?

And here are the windows photographed from the shell construction phase....

So this window is nothing special, ask them why it isn’t. Did the general contractor give your window installer a budget?

The window manufacturer has probably submitted a quote to collaborate with the general contractor.

But even that could be managed with additional charges for us... It was handled the same way with the front door...

The windows in question can be clearly seen in my profile picture.
I suspected that, but I don’t see the problem: there are four panes shown, with one division both lengthwise and widthwise; four glass panels, four frames, four sets of edges all around, so no wind can get in there.

The 4 panes are a window divided in the middle, with a horizontal fall protection bar... For whatever reason, one was included in the plans...

Even in a two-part design, I don’t see any reason for concern. The central mullion divides it into two sections—essentially just two floor-to-ceiling windows placed side by side. However, each pane acts as an independent surface exposed to wind pressure, and therefore, each one individually is only half as wide as the entire window.
