Just curious—when you were planning your place (or doing renos), did you pay attention to where your windows face for sun in the winter? Like, did you go all-in on big south-facing windows, or just kinda work with what was there? I keep thinking about adding more glass on the south side but worried it might get too hot in summer. What’s everyone’s setup?
I get the appeal of big south-facing windows for winter sun, but honestly, I didn’t go all out with them when we moved in. Our place already had a few on that side, and I figured it was enough. My worry was exactly what you mentioned—summer heat. Even now, the living room gets pretty toasty by July, and we’re not even in a super hot climate. I’ve seen friends put up big windows and then spend a ton on shades or AC later. Sometimes I think it’s better to just work with what you’ve got and maybe add some smaller windows or skylights if you need more light, instead of going full glass wall. Just my two cents.
You’re spot on about the summer heat being a real tradeoff with big south-facing windows. I geeked out over passive solar stuff when we renovated, but even with the best low-e glass, it’s tough to keep things cool without spending more on shades or overhangs. I ended up doing a mix—some south-facing glass, but also smaller clerestory windows for daylighting. Honestly, sometimes less is more, especially if you don’t want to live in blackout curtains half the year. Thermal mass helps a bit, but there’s only so much concrete floors can do.

That’s been my experience too. I went heavy on south-facing glass thinking I’d max out winter gains, but ended up fighting glare and overheating by late spring. Even with polished concrete floors for thermal mass, it only buffered the temp swings so much. Ended up retrofitting some external shades and wish I’d added deeper overhangs from the start. Daylighting’s great, but I underestimated how much sun can be too much in shoulder seasons.
Yeah, I hear you on the glare and heat. I’ve got a mix—some big south windows, but honestly, I left some smaller ones alone because I didn’t want to deal with extra shading or summer heat. Sometimes it’s just not worth the hassle or cost to chase every last bit of winter sun.
- South windows here too—big ones in the living room.
- Left the east-facing kitchen window untouched, mainly because the heat in July was brutal last year.
- Tried low-e film on one; helped with glare but not a miracle cure.
- Honestly, chasing every ray of winter sun gets expensive fast... sometimes I just pull the blinds and call it a day.
- Totally get the struggle. We’ve got one big south window, and it’s a love-hate thing—great in January, but I swear the bills spike from all the “fixes.”
- Tried those cheap stick-on films too…meh. Not a game changer for me either.
- Sometimes I just give up and let the blinds do their job. Not worth the stress, honestly.
South windows are such a double-edged sword. I tried to get clever with bubble wrap (yep, the packing kind) one winter—looked ridiculous but actually helped a bit with drafts. My partner still brings it up every time we walk by that window… “remember your ‘insulation experiment’?” Honestly, sometimes I just throw in the towel and let the sun do its thing. The blinds get a workout, though, especially on those weirdly warm February days.
Yeah, I’ve tried the bubble wrap trick too—honestly, it worked better than I expected, but my windows looked like a science project gone wrong. South-facing is great for winter sun, but the swings in temp drive me nuts. I swear, one minute I’m freezing, next I’m roasting. Curtains help a bit, but nothing’s perfect.

I hear you on the temperature rollercoaster. Here’s what worked (sort of) for me: first, I added cellular shades—those honeycomb ones. They’re not cheap, but they do help buffer the swings a bit more than curtains alone. Next, I put up a draft snake at the bottom of each window. Not glamorous, but it stops cold air sneaking in. Still get some wild temp shifts, just not as extreme. Honestly, nothing’s perfect with big south windows unless you want to spend a fortune on new glass...
