I went a different route and put 3M security film on all my bottom floor windows and door windows. The 3M film is tough stuff (youtube it) and makes it very hard to break through the glass.
I did have to beef up the door frame /lock a bit but that's it. I have no doubt some trying to break out a window will get my neighbor's attention or the dogs around the house and neighbors dogs. The youtube
video's of the 3M film are cool as folks wail away on the glass and cannot get through. Some of the video's are actual security camera's catching crook's not getting through the glass. I highly recommend it!
