"Ended up switching to thermal curtains there, which worked way better."
Thermal curtains can help, sure, but they're more of a band-aid than a real fix. I've tried them myself and while they cut down drafts a bit, the cold air still sneaks in around the edges. Honestly, if you're feeling that much cold air coming through, you might want to check the window seals or caulking—could be they're worn out or cracked. A quick touch-up with fresh caulk made a noticeable difference for me, way more than curtains ever did.
Yeah, thermal curtains are decent for a quick fix, but like you said, they're not gonna solve everything. I had the same issue last winter—curtains helped a bit, but the real game changer was weather stripping tape. Super cheap and easy to apply, and it sealed up those sneaky drafts around the edges. Might wanna give that a shot before breaking out the caulk gun...

Definitely agree with this though—checking seals is always worth it.
Thermal curtains are alright, but honestly, they're more of a band-aid than a real fix. Weather stripping tape does help temporarily—I used it myself—but if you're feeling serious drafts, there's probably a bigger issue. Could be the window seals themselves or even the frame. I ended up pulling off some molding last year and found a gap big enough to slide my finger into...no wonder I was freezing. Quick foam insulation spray sorted it out nicely. Worth checking behind the scenes if the easy fixes aren't cutting it.
