How to protect your home window?
Here some lists of recommendation how to protect your home windows;

Replace old, rotten, or damaged windows- older windows that have been weathered over time may prove to be an easy point of entry for a thief. We have seen an instance of an old, weathered, and rotten window simply being ripped out of its opening and tossed aside.
Burglar Bars or Security Film- maybe we do not favor the bars as they degrade the appearance of the home. We have not personally tested the security film but it does look like a durable product and would seem to be especially useful on larger windows.
Window security pins- window security pins lock the window’s sashes together and prevent it from opening. The pin is removed with a special key so the window can be used.
Locks- if you have locks on your windows, make sure they’re operational. Many older homes damaged locks; which are unusable. These are easily replaced and also come in a keyed variety.
