Sliding Window / July 10, 2018 / Guillaume Roussel
Casement windows are attached vertically with hinges to one side on a wall. They usually open with a crank mechanism. A single window or a pair of windows can be fitted into a frame. They open all the way outward and are wide open from top to bottom and sidetoside. A sliding window is a window that slides along a track inside the window frame. The frame may consist of many tracks depending on the number of windows on the tracks. They open horizontally and give a hundred percent view of the outside.
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.
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.
