Security sash stops, these locks are fitted in pairs to the stiles of the upper sash and prevent the two sashes from sliding past each other. There are two main forms of sash stop where either the protruding bolts are removed with a key (and can be lost) or the bolt is extracted and retracted with a key (and therefore can’t be lost). The locks can be fitted onto the upper sash about 100mm above the top of the lower sash to allow the windows to be opened a little way for some air without the worry of someone climbing in or two pairs can be fitted with the second pair fitted lower down to prevent any movement. It is also possible to buy a three position sash stop that allows two open positions and one fully locked position. To prevent damage by the bolts to the top of the lower sash the locks are supplied with metal plates. However, some older sashes incorporate decorative tops (or horns) to the stiles and these plates cannot be used. Remember to fully close and lock the windows when you go out. Why use toughened glass? Toughened glass is made from standard annealed glass which has undergone a process of heat treatment known as thermal tempering. The glass is passed through a furnace on a roller table and heated to around 650°C. This takes it past its transition temperature and the glass begins to soften. Its surface is then rapidly cooled, while internally the glass remains hot. This process creates what is known as centre tension in the glass, and alters its physical properties, resulting in a sheet of glass which can withstand much higher pressures than annealed glass making the glass extremely difficult to smash.
