Depending on whether you have casement windows, sliding windows or double-hung windows, you will need to look at different types of window locks. Different hardware stores and security companies will promote and carry various window locks depending on their experience with different brands and sponsorship issues, but it is ultimately up to you to decide which windows locks will best protect your home and your family. Your basic choices are a sliding window lock, a keyed sash lock, window latches, sliding window latches and keyed patio door locks.

Casement windows don’t generally require any extra window locks, since they are firmly secure when shut tightly and locked from the inside. Sliding windows – those that slide from side to side to open and shut – are often the easiest to break into, however. Sliding window locks are spring loaded bolts that fit into the frame and keep the panel from sliding open and may only be released with a key. Double-hung Sash Window locks are for the kind of windows that slide up to open and down to close. The lock for these windows is a small tab that is placed in the window frame, stopping the window from moving when it’s extended and again, may only be released with a special type of key. The big advantage with this type of lock is that you can fit the lock in such a way as to allow the sash window to be opened a little to allow fresh air to circulate but will not allow the window to open any further.

Window latches are very common, and simply require you to twist the latch into place under a cover so that the two window panels are attached and immobile.

Patio doors and windows are often difficult to lock up securely simply because of the combination of door handles and windows that open within the door. Patio Door Bolts can be used for these situations. Keyed patio door bolts will attach the door to the sliding door frame, prohibiting entry and may also be fitted in such a way as to permit the door or window to be opened slightly ajar allowing some ventilation.

Basically, the type of window locks you will need to install for added security depends directly on the type of windows that you have and there are a large selection of different types available from Crime Prevention Products. If you want extra protection for your home, family and belongings, it’s best to become familiar with your house fixtures and how they work so that you can lock them up appropriately.
