Convert windows from double glazing to triple glazing

Why does everyone always ask if the fittings will hold, of course they do. The fittings on the window and balcony door are the same, and does the larger balcony door break out?

Instead of reacting stubbornly like a 6-year-old, you could also answer the questions. :(

you haven't written anything yet about window sizes and year of manufacture, let me be specific. Our triple-glazed doors weigh 80kg each as a leaf, and when they are open, the lever principle affects your how old ??? frames and fixed points? Just take a look at the weights of your new panes. Nobody wants to harm you here, this is a forum, you can do whatever you want

Morning, the windows are from 2008, they are made of plastic, the pane size is 1.02 m x 0.68 m

Hello Suzuki65, of course you can easily replace the panes. In terms of weight, the wing with the new glass will not weigh 30 kg. Since the fitting is presumably designed for 100 kg, you have enough reserve. Find a window manufacturer who processes Rehau profiles and ask if they sell you the desired glazing beads and if so, what measurements they need. If you can properly pack the panes yourself, do it yourself; if not, have the window manufacturer/carpenter do it. The whole action makes sense, for example, if a previously uninsulated house is now to be insulated and the windows are already quite modern and can accommodate triple glazing. You will definitely save yourself the mess and additional work of replacing the window.
