Sliding Window / July 14, 2018 / Tearlach DuLin
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.
You will then need to install the panels into the rails. This can be hard because they are designed to not fall out. There may be Velcro strips you can install on the inside of the head rail to secure the windows. This should also let you slip in the panels. The valance returns attach to joiners but you may have to trip excess fabric. Woven wooden valances come with an aluminium L joint in the corner that inserts into the panel. The last step is to install the cords which move the panels along the track.
