Look into safety-coating your most vulnerable windows. Safety coat is an adhesive plastic sheeting that makes breaking out windows difficult.

Reason: It’s not going to be fun for them, standing in a rosebush only to discover that the window isn’t easy to break either. Instead of a quick pop, they now need to stand there and repeatedly pound before they can even reach the lock. Wait until they discovers that the window has window stops as well.

If you can afford it, there are many quality windows that are not only good to keep inclement weather out, but provide serious burglar protection, as well.
