I tried reflective films too, but more for privacy than heat. My bedroom window faces directly into my neighbor's kitchen—awkward, right? Anyway, the film did help with glare and privacy during the day, but at night it kinda reversed... I ended up feeling like I was in a fishbowl whenever I had lights on inside. Eventually switched to sheer curtains layered with heavier drapes. That combo seemed to handle both privacy and insulation better, plus gave me some flexibility for brightness levels.

Haha, totally been there. Tried reflective film once for a similar reason—my living room window faced directly onto a busy sidewalk. Great during the day, but at night... yeah, fishbowl city. Eventually ditched it and went with adjustable blinds paired with sheer curtains. Found that combo gave me decent privacy without sacrificing too much natural light during the day.
Another sneaky trick I've used to brighten rooms without flipping switches is placing mirrors strategically opposite windows or bright walls. Reflects daylight deeper into the space and makes everything feel more open. Also, swapping out dark furniture or heavy rugs for lighter colors can make a surprising difference.
Honestly though, nothing beats having flexible window treatments that you can tweak according to time of day or season. Glad you found something that works!
I feel this. Had a similar issue in my old place—big windows, great sunlight, but zero privacy after dusk. Tried sheer curtains alone first, but they didn't cut it at night. Ended up layering them with bamboo blinds, which let me adjust privacy easily and still kept things feeling airy. Also noticed that adding lighter-colored throw pillows and artwork helped bounce natural light around the room without needing extra lamps.
Layering sheer curtains with bamboo blinds is a solid approach, especially since bamboo has that natural texture that diffuses light nicely. Another option I've found effective is using frosted window film on the lower half of windows—keeps privacy intact without sacrificing daylight. Also, strategically placing mirrors opposite windows can amplify natural light significantly. Just be cautious with mirror placement to avoid glare issues... learned that one the hard way.
Totally agree about the mirrors—had a client once who placed a huge mirror directly opposite a west-facing window. Gorgeous in theory, but every afternoon their living room turned into a blinding spotlight... lesson learned! Another trick I've found helpful is using lighter-colored rugs or flooring. Dark floors can absorb a surprising amount of light, so swapping in something lighter—even just a large area rug—can really brighten things up without much hassle.
