I would like to hear your opinion on the choice of roller blinds, as I am still undecided.
We have to choose aluminum or plastic roller shutter profiles for the upper floor.
I'm thinking of choosing the cheaper option. Just because I think if someone breaks into the house, they probably won't put up a ladder to get in upstairs. I would choose aluminum, which has easy access.
Am I wrong about that?
Aluminum can be much noisier when it rains than plastic, and aluminum is much more expensive.
As for burglary protection: Standard aluminum roller shutters are not burglary resistant! Don't count on protection in any case!
The burglar doesn't care if there is a latch and what it is made of.
It takes exactly 2 seconds to get the bolt out of the guides. We have aluminum everywhere, imho, it just looks better when it's uniform.
I would make it even top/bottom. How much are you saving on each window? Depending on the color/surface, aluminum looks better.
As mentioned, aluminum roller shutters also delay burglary for a maximum of 10 seconds.
One more thing: aluminum shutters with a slightly shiny finish reflect sunlight better and are supposed to heat up less.
For increased burglary protection, you have to resort to extruded aluminum with a synthetic resin filler. There is also a snap-on anti-lift device and more stable outer rails. Unfortunately, it costs a lot of money. I'd save myself the hassle of the first floor. Burglars are looking for victims, not sports.
