Did you ever seal up the cracks later, and if so, did it make a noticeable difference on top of the triple-pane?
Honestly, sealing up the cracks after the windows was like putting the cherry on top. The triple-panes made the drafts way less noticeable, but once I finally got around to caulking and foam-filling, it felt like I’d wrapped the whole place in a warm blanket. As for install—older cabins can be a pain, yeah, especially if nothing’s square. But it’s totally doable, just takes a bit more patience (and maybe a few extra shims).
Yeah, sealing those gaps really does make a difference, even with good windows. I’ve worked on a few cabins where folks thought the fancy glass would solve everything, but if the rest of the envelope is leaky, you’re still losing heat (and money). Triple-pane is great, but honestly, it’s the combo of solid install and attention to the little cracks that really locks in the comfort. Shimming out-of-square frames is always a bit of a wrestling match, but it’s worth it in the end.
