This Incredible Tool (preventing insolation) That Our Ancestors Used To Keep Cool In The Summer.

Yeah, they cost money. So does installing air-conditioning. But they use no energy ( that’d would be bad for fossil energy-producers).

    What about some rollo blinds? We have them shut during daytime in summer in the rooms we don’t use all the time. They also help sleep in the dark if that’s your thing. The drawback is that they often create a weak spot wrt. Insulation.

      Interior blinds are mentioned in the video: basically since they’re behind the glass the energy is still getting in and green-housing a bit. Blinds heating up is heat inside the room. Also block the view out, which awnings don’t.

        If I’m interpreting the other poster correctly, they might be referring to what’s known as Roll-Laden in German, and they’re outside the glass.

          Makes sense.

          In that case better for efficiency than interior blinds, but still blocking your view out.

          Would be handy for an especially hot day or week, but I wouldn’t like to have to keep my windows covered all summer.

            They’re actually way more convenient than that! You have a strap on the inside of the window that you can use to raise or lower the shutters as much as you like. When it’s fully closed, the light is blocked out nearly completely though.

          The video mentions exterior roller blinds as well, wasn’t too in-depth but his main down points for them would be they still radiate heat close to the glass and they block all sunlight as well as airflow.
