Hello everyone,

I have three wide but not very tall basement windows without shutters. A potential burglar, if slim enough, could break the glass and enter my townhouse through these windows. I want to prevent this in advance, hoping that such a burglar will move on to my less-liked neighbors and empty their place instead.

The house has external thermal insulation, which means the windows are recessed about 20 cm (8 inches) inward. I don’t want to simply screw a grille onto the exterior wall, as that looks too much like a prison. My plan is to saw a typical stainless steel handrail (maybe 8 cm (3 inches) diameter) and place it centrally in front of the window, horizontally or with two vertical bars.

Is this a good idea? What is the best way to install it? Should I use a hammer and chisel to remove the insulation and plaster/masonry, lay the bar inside, and then cover it with plaster so the bar can’t be removed? Unless, of course, the slim burglar also has a long chain and an all-wheel-drive SUV, then none of this would help.

I hope you understand my problem and would appreciate your advice!

...that all sounds very amateurish!

Anything installed as grilles or protective devices must be anchored into the masonry.

Either with anchor bolts or glued-in threaded rods.

Before the burglar has a good laugh, please consult the local metalworker.

So the goal would be achieved. No break-in – the burglar had the last laugh. But honestly, I would rather have something custom-made and possibly get advice.

Why not from the inside? This way, you don’t have to partially damage the insulation or facade.

I agree with the others so far. As you describe it, the burglar coughs forcefully and the parts fall down.

However, then you have the problem that you can no longer open the window. Unless you design the protection so that it can be opened or removed.

Hello MaxPower90

I planned the security of my house in cooperation with the police advisory service. There was a very knowledgeable person involved who took my wishes into account as much as possible. He was also an expert in the field. Just give it a try and ask. Usually, they also offer on-site visits.
Another advantage: all of this is free of charge.
