Hello everyone,
We have three very large windows in our living and dining area facing south.
As a result, it gets extremely warm as soon as the sun shines on them. During the summer, we almost always keep all the roller shutters down, making the room completely dark.
We have now received a suggestion to apply reflective film on the outside. Does this really provide the desired effect? Has anyone had any experience with this?
Thanks and best regards

Retrofitting external blinds isn’t possible because there’s a roller shutter box.

Air conditioning is the simplest and possibly most effective solution. I think so too.
Since we recently installed photovoltaic panels, we generate our own electricity on sunny days anyway.
Great, large south-facing windows to let in full sun and then cool down with air conditioning... what an energy madness.
For a public building, this would cause a media outcry about poor planning and waste of taxpayer money.
Why did you even plan for roller shutters instead of venetian blinds or shutters right from the start?
Sure, retrofitting is possible, but it’s complicated and expensive.

If you have an air conditioner, you should at least install internal blinds as well. It’s not as effective as external shading, but it’s better than nothing. Otherwise, the air conditioner wouldn’t be able to cope with direct sunlight and would have to be significantly oversized.
When shading, make sure to keep a distance from the window pane and pay attention to positioning to prevent heat buildup and cracking.
