Ask three experts and you get six opinions.
We want to install electric roller shutters. The building price includes shutters with plastic slats. Now we’ve heard that beyond a certain width, only aluminum is recommended because plastic slats can deform. But exactly what width is that? How much does heat affect this? Of course, the largest window areas face south.
The answers from the window installers confuse us more than they help. One says from 4 m² (43 sq ft) it has to be aluminum, another says up to 3 m (10 ft) wide and 4.5 m² (48 sq ft) plastic is still okay, and the next only uses aluminum because of the heat in the south. The manufacturer doesn’t provide any information at all – which I find really disappointing! It’s a total mess.
Aluminum is quite expensive and we don’t want to spend unnecessary money. But of course, it would be awful if the shutters deform in the sun. Our largest windows are 2100 mm (83 inches) high and 1650 mm (65 inches) wide. What would you choose?

We are also getting plastic roller shutters. Unfortunately, I hadn’t considered this beforehand, and when it came to selecting options, I didn’t want to pay the additional cost. Later, the site manager told us: "In summer, never close the roller shutters completely because of the buildup of heat between the shutter and the window."
That puzzled me a bit...The gentleman is right about that.
You can lower the shutters so that the ventilation slots remain open.

ns was later told by the site manager: "In summer, never fully lower the roller shutters because of the heat buildup between the shutter and the window."
That confused me at the time... That confuses me too.. what exactly happens because of the heat buildup?

That’s confusing me as well.. what happens because of the trapped heat? It will cause the window to break! So be careful inside the house.

Deformation causes the roller shutter slats to jam in the guide rails and the roller shutter box.
This also accelerates wear and tear!!!!

We had gray plastic roller shutters for 18 years, measuring 2.8 x 2.2 m (9.2 x 7.2 ft) facing southeast. No repairs, no patina or significant fading, no deformation. Whether aluminum would have been better – no idea. The plastic definitely worked. Respect!! You obviously have good quality! After 7 years, I’ve seen quite different results, especially regarding patina and fading.
