Pannelli isolanti per pavimenti. Polistirolo da 10 mm, con uno strato esterno riflettente. Alla fine di giugno all’interno ci sono stati più di 30 gradi per più di due settimane, anche di notte. Tutte le finestre sono rivolte a sud. Ho visto questi pannelli per 35 euro e ho deciso di ritirarli. Il pacchetto era appena sufficiente per ogni finestra dell’appartamento.
Aria condizionata l’anno prossimo, spero che mi possa aiutare ancora quest’estate. Ogni finestra ha due finestre singole che possono essere aperte singolarmente, con qualche centimetro di spazio tra loro (antica zweifachverglasung). Spazio appena sufficiente per questi pannelli. Per favore, dimmi che questo non surriscalderà le finestre o qualsiasi altra cosa pericolosa.
Modifica: se a qualcuno si sono rotte le finestre a causa di qualcosa come me, per favore dimmelo. In realtà sto pensando di rimuovere questa configurazione adesso. Così tante persone mi dicono che il vetro esterno si romperà. Anche se ho un vicino al piano di sopra che ha fatto lo stesso con carta stagnola su cartone per alcune settimane, e posso vedere un appartamento nella mia strada che ha anche materiale riflettente all’interno. Non ne sono davvero sicuro. Finora la maggior parte delle persone che dicono che si spezzerà non ha detto che sia realmente accaduto.
Edit2: troppe persone mi avvertono e non voglio correre rischi. Per le finestre che ricevono il sole diretto, ho semplicemente girato la parte riflettente verso l’interno. Fondamentalmente ora è come una cortina oscurante di polistirolo molto scura e isolante. Non so quanto aiuterà, vedremo. La finestra nelle immagini è ombreggiata da un balcone sovrastante, quindi sto pensando di lasciare il lato riflettente verso l’esterno.

Interesting idea. Please keep us updates about how well it works (or doesnt(
Just get an air conditioner man. Please.
Please tell me you stuck that to the outside of the windows, not between them.
(It could go ok with the panels between the two window panes, but it might very well also just plain crack the glass in some places. If you own the place, it’s your risk to take, if you don’t, I’d very much advise to stick them to the outside of the window if I were you. Yes, it’s less convenient, but it’s also safer.)
I would recommend sticking them fully on the exterior rather than between the panes of glass. Otherwise the sunlight will come through the first pane, reflect, and go back out through the same pane, doubling (roughly) the heat the glass is subjected to and increasing the chances of it shattering from stress.
Yeah, it will work better than curtains, since they reflect more heat to the outside.
Do you know the movie Hell (2011)?
I mean, this should work fine. It’s basically the same principle as people who use reflective covers for their windshields.
My across-the-street neighbors are using pieces of cardboard that are wrapped in emergency blankets (so that they’re reflective). Hasn’t seemed to hurt their windows.
It will help a bit, but isn’t a miracle worker.
Is it between the glasses or completely on the outside? If it’s between, it can easily destroy the glass
Is theres a link or where can i get this?
If you have exterior walls that trap heat, this won’t help. Your apartment will still be a backing oven. Just darker.
Problem is, doesn’t really matter that they are in between two windows, the reflective side still faces towards the glass, so it might overheat and damage it. 🙁
>At the end of June, it was over 30 degrees inside for more than two weeks, even at night.
Helene Fischer’s Schlager banger “Atemlos” gets a completely new meaning…
I’ve not seen those tiles before, but anything that reflects the light back out should be good.
My windows are foiled with the cheapo aluminium foil from Rossman.
Just tape to the inside of the windows, shiny side facing out. It makes the room SOOO much cooler.
Oh my God, not another one of those.
Here’s some more information for you:
**Point 1**: Whether indoors or outdoors, micro-cracks can form in the glass if it’s just a standard window.
**Point 2**: No insurance company in the world will cover the damage if the landlord notices it.
**Point 3**: If you’re unlucky and the landlord is out to get you, they can cite this as grounds for terminating your tenancy.
**Point 4**: The second-worst thing that can happen to you is that a neighbour might be bothered by the reflection and report you for causing a nuisance.
**Point 5**: This is what happens if you’re really unlucky. If you live near a road and the sun happens to reflect off your window, blinding a driver and causing them to crash, you’re absolutely done for. Endangering road safety, possibly causing bodily harm and damage to property.
In other words, you’ll never be happy again.
The window pane in my bedroom cracked because of this
i use this on the outside :

Works well ( 4th year now).
Dont put the stuff on the inside of the windows, you want the thermal energy stay outside !
Reflecting IR is what its for
Look, if you’d have told me that’s the north facing side then I’d have said okay, take the flip, it’s up to you.
But since those are south facing windows which will take the full blown sun over a couple of hours every day you created a ticking time bomb.
It’s not about *if* it will fail or cause issues, but *when*.
As others already mentioned, no insurance will cover this, in the worst case you’ll need to pay for a full set of new windows. Personally I wouldn’t risk it and ask a professional. We aren’t in your appartment, we can’t judge the quality of the windows and whatnot, but from what we’re able to see it’s a dumb idea.
Put it on the outside of the outer window with the reflective side facing inside.
The problem with Germany, in a nutshell. A lot of advice from people living their entire life in a coutry that did not have such severe heatwaves in the past.
OP: take your point to a sub from South-Eastern Europe where such heatwaves are common in the summer, and where people are using exactly your solution without windows cracking, or glaring drivers, or any other “end of the world” scenario.
(Source: I had such an improvisation in place in Southeastern Europe for 6 years, years ago when AC was expensive and not common for apartments. And my window panes survived. And the window panes of all my friends that used this method also survived, and none of them worried so much for a simple f***ing solution to a common problem, as the window panes will take way more heat than people here think; it is the sudden change of temperature (heat shock) that breaks them, not the temperature itself)
