I ordered a reflective film from https://www.tintfit.com/shop/
a couple of weeks ago and just finished installing it on my balcony windows. It definitely reduced the heat inside the room, which was my main goal. I wouldn’t say it’s a super quick DIY job though — you need patience. If you rush it, you’ll get bubbles everywhere (learned that the hard way). But once it’s done properly, it looks really clean.
