Building cheaply - this is how it can be done too!

About the windows: 110 wide by 137.5 high with a sill height of 100 is indicated all around in our plans. Shell construction height 275. What additionally saves. Ikea standard pleated blinds at 20,- euros fit like a glove. What exactly are [Unterputzarmaturen]? Picture? Karsten

But with 137.5, I think it only fits without a shutter.

You don’t give any here either. The roller shutter is an invention of neurotic Catholic altar servers from the Paderborn area and spread from there to the south, also conquered the Stasi-damaged East, the weekly cleaning damaged Southwest, and has not advanced to the north. Someone once tried a substitute for roller shutters and venetian blinds here. Bankrupt. Karsten

or the invention of people with children who appreciate a dark nursery in the summer

Here in the south, there is actually no new building without [Rollladen/Raffstores]

No, not here either. I also see it more as additional security.

What is the roller shutter supposed to provide in terms of security?
