Now they're the perfect length.

I cannot reconcile curtains and radiators. Either the curtains are floor length and insulate the radiator so it doesn't heat the room well, or the curtains are, well, not floor length.

    So radiators were placed beneath single pane windows in ye olde days to prevent condensation from forming on the window, dripping down, and rotting the sil, wall, and everything beneath the window. With modern windows, this isn't really a thing anymore.

    This radiator was not placed to heat the room.

    No, multipane windows still need airflow to “prevent”condensation. It’s why air vents are still placed under them.

    Without forced heating, you use radiators to create airflow.

    Even triple paned argon filled windows will condenstate and frost in -40c

    There’s nothing you can do to prevent it, you use airflow to remove the moisture that will always form.

    Windows are also the source of most cold entry into the room, so you put the heat there to minimize it. They are properly placed to heat a room. If you mean to comfort a human, than use a portable heater.

    Condensation forms when the temp on the inside surface of the pane drops below the dew point of the air inside. Doesn't need to be -40c outside and thats not even a sufficient condition on its own.

    Condensation can form anywhere, on the walls, floor, doors, etc... Just need the indoor surface temp to drop below the indoor dew point. Doesn't have anything to do with air flow.

    Heat is placed below the window to keep its surface temp above dew point.

    Your entire comment ignores how humidity plays a role, which is rampant in houses when you bring snow in from outside, or as soon as you open up any door to go in or out, the air rushes inside causing a moisture spike for up to hours at a time.

    It’s not JUST temp. You can have condensation at 20c with a high RH, or you won’t have any if you can manage to keep the RH at a manageable level and prevent pockets. Which is another reason why airflow is important, there’s multiple like mold prevention, dust, mildew, pollen, hair, dander, etc. you NEED airflow. And that’s done by utilizing the physics of the difference between hot and cold and the drafts it creates. Especially when you don’t have forced air central conditioning/heating.

    Airflow is the only thing that mitigates it. If you have a glass of water, it can have condensation on it, but place it a flow of air (like a fan) it will evaporate and leave the glass feeling dry. Thats how you prevent/remove condensation. Heating the room, only changes the RH so much.

    You must live in a fair weather place and have never experienced cold weather have you?

    Will research even change your mind? there’s hundreds of studies that have been done about how crucial airflow is to basic air condition. This study even pulls research from 1965, so it isn’t like this is something new either….

    Humidity is a piece of defining the dew point. They're two sides of the same coin

    For research, I have ms in mechanical engineering focused on building energy systems and have worked in commercial construction for years.

    Ive lived in Canada and Chicago.

    Indoor dew point and indoor surface temperature and all thats required. Air flow can vaporize condensate, but wont prevent its formation.

    Yeah bullshit, anyone with a basic understanding of “building energy systems” would understand that radiators are placed underneath windows to heat/condition and provide airflow to (see link in previous comment for why this is so important) a room. It’s thermodynamics.

    Without airflow, a couch against a wall, or curtains and blinds on a window, creates a pocket. Where if the room was properly conditioned, it could still have condensation and mold since there’s no airflow to mix the air.

    I have always been terrible with a sewing machine because I spend 10 years between attempts. I really should get one sit down and actually just spend a weekend trying to make a bunch of things.

    What all did you use to do this? Or did you do it with just a needle and thread an a lot of patience?

    Singer sewing machine off FB Marketplace. Chalk, seam ripper, scissors, measuring tape. Took me better part of the afternoon. Messed up a little on the first attempt so had to undo but it turned out okay.

    Hemming is pretty easy and a great place to begin sewing. It's a lot of fun and can absolutely be done without a machine.

    Years ago I went to a convention and instead of taking the wise advice of start with hemming and taking small steps I tried making a full on jacket. Thankfully it was Merlin's jacket from the show so it naturally had a ragedity look to it. Most of the seems I did looked pretty bad if you looked close but overall it didn't fall apart and everyone knew what it was right away so I called it a not terrible idea and haven't used a sewing machine in the 14 years since.

    Doing something like the curtains where I'd have to see it every day I would want to do a much better job. But thanks for the list of need to haves, hopefully I'll add that to my to do list and who knows, maybe someday I'll make useful things like you, haha

    Oh that length is so satisfying! Not too long, not too short...just right. Hemming looks flawless well done

    One of these days I need to get around to shortening my venetian blinds.

    I let them hang a bit longer so in winter I can tuck them behind the radiator. That way the warm air flows into the room and not to the cold window where it cools down without any benefit to me.

    Everything that separates warm air from cold windows keeps you warmer and saves energy.
