ᐅ Which type of wood is best for 1.5-meter-wide panels?

Hello,

we are currently in the process of selecting the wood for our windows.
An acquaintance mentioned that pine wood might not be stiff enough for wood-aluminum windows with such wide sashes and could potentially warp.

One sash weighs around 200 kg (440 lbs). He recommends using woods with a higher raw density.
Unfortunately, these tend to be somewhat more expensive. Does anyone have experience with this and can offer some advice?

The window manufacturer says pretty much the same, but of course, they also want to make a sale...

I don’t primarily see this as depending on the type of wood. Wood-aluminum windows are already a delicate combination, and a 1.50 m (5 ft) sash width is generally quite ambitious. Especially if the sashes are lower in height than in width, I would advise against it. Aluminum windows can also be laminated. Therefore, as a Plan B besides reconsidering the sash dimensions, I would take the opposite approach for these windows: use aluminum as the main (and outer visible) material and create the inner visible side with a wood-look finish.

... and perhaps the practicality of 150cm (59 inches) window sashes should be reconsidered.

Therefore, I would suggest (as plan B alongside reconsidering the sash dimensions) taking the opposite approach for these windows—using aluminum as the main (and outer visible) material and finishing the inner visible side with a wood look.

That’s not possible in this particular case, as we are getting the windows through a general contractor we know, who passes on his discount from the window manufacturer. Unfortunately, they don’t produce aluminum windows.

Yes, we have already thought about that. But what’s the alternative?
Isn’t that a bit short for a sliding door? We can’t make the window wider because the plans have already been approved.

Also, a sliding door would cost 3,000–4,000 more right away.
That’s not really necessary either.
Especially since the windows are already expensive enough.

These are all things you don’t really question at the beginning, thinking, “The architect knows what he’s doing.”
Now we have a mess.
The next house, I will plan myself.

I can’t find these windows anywhere: neither in https://www.hausbau-forum.de/threads/angebot-zu-teuer-architektenhaus-in-pforzheim.24404/ #1 nor in https://www.hausbau-forum.de/threads/Grundriss-wie-veraendern.24706/page-24 #142 – there are double-wing windows with a width of 200cm (79 inches) and also some with widths of 300cm (118 inches) and 325cm (128 inches), but these are all triple-wing. So where do the 150cm (59 inches) wide wings come from?

Hmm, something seems odd here. You’re right about the south elevation. There, three sash windows are visible each time. But in the ground floor plan, only one mullion is shown at the 3m (10 feet) windows. On the upper floor plan, there are two.

Or am I mistaken, and the mullion posts in the floor plans don’t actually represent the mullions?

Honestly, I based the offer on the floor plan. But it’s good that you noticed this. I’ll have to ask about it right away.
