If you are thinking about increasing the security of your home, chances are that you are primarily thinking of installing security locks, possibly with extra security, on your doors. Obviously this is important, but do not forget that windows also pose a risk of burglary. You can still have the best locks on your doors, if your windows can be opened in no time without much effort, that effort will be largely undone. If you know that a burglar is always looking for the weak spots of a house, you also know that he will soon discover that your windows are only limited in security and therefore not too great a challenge. So it's time to also thoroughly check the security of the windows.
