Consider Shatter-Free Film
Coming home to a smashed window is something nobody wants to experience since this not only means replacing the glass but also means someone has been in your house and ransacked it.
You can prevent this from happening by investing in some shatter-free film. Paste this on the inside of all your windows. It won’t be visible but will keep your windows much safer since if the glass won’t shatter, a burglar can’t get in.
