Comment on UK weather: Amber extreme heat warning issued as 35C heatwave approaches
crapwittyname@feddit.uk 9 hours agoAll great advice. Can I just add two details?
- Install the foil on the outside of the windows if possible. The sun will still heat the air between your window and the foil, raising the temperature in your room, if you install on the inside.
- Kitchen foil works just as well. Harder to install, but cheaper. I crafted some sun blinds with tinfoil and cardboard that I use every year.
I can’t stress enough how much is a difference the foil blinds make. Goes from unbearable to comfortable almost immediately.

Good on both points.
Installing on the outside is a complete pain in the arse however. The superfoil is reflective enough that the extra gain wasn’t worth the extra hassle. It also looks a lot better from the outside (if it matters to you what the neighbours think).
As for the foil. It works, but is very hard to apply. Milar space blankets are a bit easier, but not much. That’s how I ended up with the super foil. It’s stiff enough to handle, but flexible enough to roll up for storage. A cardboard backing also makes sense, though it would have made storage harder for me.
It’s also worth noting to not leave it up for too long. Cannabis growers use a similar method to try and hide drug labs. You might get a visit from the police (hopefully politely) if it’s up for too long.
