Sliding Window / July 22, 2018 / Christabel Gosselin
Many new sliding windows have key locking latches already installed. Some allow the window to be locked slightly open for ventilation. If your home has these window locks they are usually secure enough to keep your insurance company happy. If your home has only a simple nonlocking latch you should secure them with a keylocking sliding window lock or a window grill. Installing window locks yourself will cost AUD$15$20 per window. Having these locks supplied and installed by a locksmith will cost $40$50 per window.
Sliding window locks are often called vent locks as they allow the window to be locked slightly open for ventilation. The recommended gap is 100mm but never have more than 150mm. The theory is that if a head can get through a window a person can squeeze through. The venting position is not as secure as when the window is shut and locked. Therefore you should only leave your windows locked open you are at home.
Always be sure to avoid abrasive cleaners such as cleansers and products containing bleach as they can affect the vinyl surface or the caulking around the window. Also avoid using a power washer or hard spraying hose as this too can damage the caulk. Besides occasional exterior cleaning the tracks and runners on your vinyl sliders should be checked every few weeks to make sure they are clear of debris. Vinyl sliding windows glide horizontally and open the full length of the window.
