Sliding Window / July 30, 2018 / Guillaume Roussel
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.
To install sliding window locks you need the following tools: Sliding windows can be lifted to varying degrees within their track. If you are using the venting position it is a good idea to fit something in the track to stop the window from being lifted. Small blocks of wood or plastic or just a screw can be used. If fitted correctly this can make the window a lot more secure especially when locking the window in the open position.
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.
