Hello,
we are currently in the phase of selecting windows with the carpenter.
I have received several offers.
All windows are triple-glazed. However, one carpenter says that nowadays windows with a frame depth of 82mm (3.2 inches) are usually installed, while another says 70mm (2.75 inches) frames are sufficient. Of course, the 82mm frames have a better Uw value (thermal transmittance). But how noticeable is the difference? Does it perhaps also look better aesthetically?
Please share your experiences.

The difference will not be noticeable to you as an occupant.
Whether the difference matters to you as the payer depends on the additional cost, the heating system, the duration of use, and the impact on the resale value.
Aesthetically, I find the slightly thicker windows more attractive in the thicker walls. It’s purely a matter of personal preference.
Trust your instincts; you won’t make a significant mistake either way.

Well, that’s already quite a statement.
One window manufacturer even goes so far as to say they would now only install windows with a minimum thickness of 82mm (3.2 inches).
I would say, my gut feeling is: more windows = better insulation = improved performance... I still need to find out exactly how much the additional cost will be.
But thanks for now.

Your view does not fully reflect reality. We have triple-glazed 82mm (3.2 inch) Veka profiles. The window is sturdy, heavy, airtight, and warm, but also affordable; it is not flimsy.
My son-in-law has Rehau 70 profiles. Thinner, more delicate, lighter, more expensive, also airtight, also triple-glazed, also not flimsy, but more elegant in appearance.

So, were the 70mm (2.8 inch) windows more expensive in this comparison? Of course, it's not that easy to compare when dealing with different manufacturers. Looking at VEKA, for example, 70mm (2.8 inch) versus 82mm (3.2 inch) windows with otherwise exactly the same specifications, the 82mm (3.2 inch) ones are definitely more expensive. However, for me, that shouldn’t be the deciding factor. If, in the end, there really isn’t a significant difference, I would naturally prefer to save some money.
Well... I am still leaning towards the 82mm (3.2 inch) windows.
