Pretty much the title. It get quite hot here in Europe.
You can buy solar reflective film kits that let light in but reflect out 99% of infrared energy.
It can't hurt. Make sure the aluminum isnt reflecting sunlight in high concentration onto anything in close proximity as this could create a fire hazard. It looks rather matte though so you should be fine.
Works like a charm. I've done this on all my windows and I'm waiting for the police to break down my door. It looks sus af but I don't care because it's cool at least.
Could get condensation when it gets colder in the autumn.
As long as it's not across the whole ceiling of a bar.
It's a bit off topic, but damn. If you got a nickle for every time a double digit number of people were killed by that exact scenario, you'd have more than one nickle, which is ridiculous.
I don’t understand the on-top part.
It is a good idea to cover windows when it is really hot outside. Made sure you are allowing your attic to properly ventilate. So providing that covering the windows doesn’t interfere with that you will be fine.
Also there is no need to use Tinfoil. A white surface will have the same effect.
Here's more ideas to cool the house
The foam itself is quite reflective. And would look more like curtains than a crack house.
What is the hot glue gun for? That'll melt the foam...
Aluminium foil has a shiny side and a dull side too so make sure you use the shinier side for a bit more efficiency.
I would make sure to secure the panels somehow so they don't get blown away by wind, and maybe check that the reflection doesn't cause a hazard, e.g. to passing traffic.
I do this with “reflective bubble insulation” brand: Reflectix with a spray adhesive.
Unfortunately it looks like a reflective surface work best with an air gap so directly against the window might not be doing much. But certainly the insulation will.
