Good points about the energy audit—wish I'd done that before jumping into my window upgrade. I noticed a decent improvement with triple-pane Kolbes, especially in noise reduction, but you're right...the insulation difference wasn't huge until I tackled attic insulation later. Ever checked around recessed lights? Found some sneaky drafts there myself. Anyway, sounds like you're on the right track—good luck sorting out those cold spots!
Triple-pane Kolbes are solid windows, no doubt, but did you check your framing and sealing thoroughly before the install? I've seen a ton of cases where high-end windows didn't deliver because of overlooked gaps or poor flashing. And recessed lights are sneaky...have you tried those airtight covers? Helped me a lot with drafts in my own place. Anyway, sounds like you're getting there step by step.
"And recessed lights are sneaky...have you tried those airtight covers?"
Ha, recessed lights are the ninjas of heat loss—I chased drafts for years before realizing they were the culprits. Airtight covers definitely helped, but honestly, sealing around my attic hatch made a bigger difference. Always something new to discover in homeownership...
Kolbe windows are solid, but honestly, windows alone rarely solve the whole draft issue. I spent a weekend installing airtight covers on recessed lights—
—and sealing attic hatches. Those small fixes made just as noticeable a difference, surprisingly."recessed lights are the ninjas of heat loss"
Kolbe windows definitely have their merits, but you're right—addressing drafts usually requires a more holistic approach. I installed Kolbe windows about two years ago, and while they noticeably improved insulation and reduced noise, I still felt cold spots around the house. After some investigation, I realized the rim joists in my basement were poorly insulated. Spent a weekend sealing and insulating those with rigid foam and spray foam around the edges, and the difference was immediate. It's surprising how much heat loss occurs through these overlooked areas.
Also, don't underestimate the impact of electrical outlets and switches on exterior walls. I used foam gaskets behind the plates, and while it seemed minor at first, it actually helped reduce drafts noticeably. It's these small, incremental improvements that collectively make a significant difference in comfort and energy efficiency.
Windows are important, but they're just one piece of the puzzle.
"Also, don't underestimate the impact of electrical outlets and switches on exterior walls."
Glad you mentioned this—I just moved into my first house and noticed drafts near outlets too. I tried the foam gasket trick, and it made a bigger difference than I expected. Next up is tackling the basement rim joists... did you find rigid foam easier to handle than just spray foam alone? I'm new to DIY insulation stuff, so any pointers would be great.

Rigid foam was definitely easier for me—less messy and simpler to cut accurately. I just measured each joist cavity, cut the foam slightly undersized, wedged it in place, then sealed edges with spray foam...worked great. Spray foam alone gets tricky fast, especially overhead.
Rigid foam is definitely the cleaner route, especially overhead. Spray foam can get messy fast if you're not careful—seen plenty of DIYers regret tackling ceilings with it. One thing I'd add though: sealing around outlets and switches is often overlooked. Even with upgraded windows like Kolbe, drafts can sneak in through electrical boxes, especially on exterior walls.
Did you happen to use foam gaskets behind your outlet covers? They're inexpensive and surprisingly effective at cutting down drafts. Also, did you notice a significant improvement in comfort after sealing the joist cavities? Curious if you found it made a noticeable difference in heating bills or overall room temperature consistency.
In my experience, homeowners often underestimate how much heat loss occurs through these small gaps. Windows are a big-ticket upgrade, but sometimes it's the little details—like sealing electrical penetrations—that really tighten up a home's envelope.
Totally agree about the foam gaskets—cheap and effective fix. Did you also caulk around the window trim after installing the Kolbes? I've seen people skip that step, thinking new windows alone solve everything. When I did mine, sealing those small gaps made a noticeable difference in drafts. Curious if anyone else found that too...
I did caulk around the trim too, and you're right—it definitely helps with drafts. But one thing I've been wondering about lately is insulation behind the trim itself. When I replaced mine, I noticed the original installer barely put any insulation around the window frames, just a few random scraps of fiberglass here and there. I ended up using spray foam before reinstalling the trim, and it seemed to make a noticeable improvement in comfort.
Has anyone else checked behind their window trim for insulation quality after upgrading windows? I'm curious if the lack of proper insulation is common or if I just got unlucky with my original install...
