I think it would. I live in the deep south and have an enormous east-facing window in my bedroom. It gets miserably hot in there in the summer. I put a thermal blackout curtain up and it's made a big difference. Not as much as I'd hoped, but I'm fighting the ridiculous southern sun; I think for what you're needing it for, it would do the job.

It absolutely will help. It doesn't need to be anything fancy. Any blanket that would keep you warm in bed will work, even better than blackout curtains since a blanket will have a good R-value.
Blackout curtains like others have recommended are not great insulators. They simply have an opaque, rubbery, white backside to reflect and block sunlight. The will block currents of warm air from moving between the rooms, but a blanket does that, too, and provides a higher R-value.
I live in an RV van and had blackout curtains between the front and back of the van for years before I decided to also add a quilt, and it made a huge difference in keeping the back warm in winter, and keeping the sun-caused heat out of the back in summer.
When I lived in an apartment I used to have a blanket between the kitchen and living room. The living room had an AC unit, and the kitchen had.... an oven. The difference the blanket made was astronomical!
Yes!
My dad's family was kinda poor growing up and lived in a two story house, and his dad hung a heavy blanket in front of the stairs (they were walled in) to keep the heat/AC downstairs
Without AC to move the air around, anything you can do to prevent the hot air leaving the kitchen will keep the rest of your place cool. In our house, unless the ac is running, when we close doors between rooms in can make a 5-10 degree difference.
I canβt seem to figure out how to reply to specific comments or upvote, but thank you all for your replies! Iβll be adding a thermal curtain soon.
What app?
Try tapping the comment, or tapping and holding onto it. Options should pop up.
If that doesn't work, try swiping left or right.
These are the 2 most common gestures I've seen on most Lemmy apps.
Iβm on Memmy and it was the swipe! Going from lurker on Reddit to active here has been a journey. Thank you!
Yes. I've done this in a couple different places. A moderately heavy blanket will insulate the rooms from each other (hot or cold). Thermal curtains may work as well.
