What's the best way to protect basement windows from burglary?
Revision 1
I have a total of 3 wide but not tall basement windows without shutters. Through them, a would-be burglar, if slim, could break into my patio house by breaking through the glass.
I have insulation on the outside of the house, which also means that the windows are "offset" about 20 cm inward. I don't want to just bolt the bars to the wall of the house from the outside, it's too much like a prison. My plan is to cut a regular stainless steel handrail (maybe 8 cm in diameter) and place it in the center in front of the window, horizontally or two vertically.
Is this a good idea? What is the best way to attach it? Should I use a hammer and chisel to cut into the insulation and plaster/stone, put the rod "in" and then caulk everything with plaster so the rod can't be pulled out? Unless, of course, the slender burglar has a long chain and a four-wheel drive SUV, in which case that doesn't help either.
I hope you can figure out what my problem is and would really appreciate your advice!
