Sash Window Security Features
For expert assistance, explore our expert sash window replacement guide.
Sash windows are beautiful and historically significant, but their traditional design can raise security concerns. The good news is that modern security upgrades can dramatically improve the safety of your sash windows without affecting their appearance. From discreet key-operated locks to integrated sash stops, this guide covers the best security features for period sash windows in Edinburgh.
Sash Stops and Restrictors
A sash stop allows you to lock the window in a partially open position — typically 100mm or less. This provides ventilation while preventing the sash from being opened far enough for someone to enter. Sash stops are also an excellent safety feature for homes with young children. They are discreet, fitted to the top of the bottom sash, and do not alter the window’s external appearance.
Key-Operated Sash Locks
Traditional sash window fasteners offer minimal security — they can be easily opened from outside using a thin blade. Key-operated sash locks replace the central meeting-rail fastener with a lockable mechanism that secures the two sashes together. These locks are available in period-appropriate finishes to match your existing ironmongery.
Frame Reinforcement and Anti-Lift Devices
Even a locked sash window can be lifted out of its frame if the side channels are accessible. Anti-lift devices, also called security pegs or sash blockers, prevent the sash from being lifted out. These are small metal pins that block the sash’s vertical movement beyond a certain point, and they are completely invisible when the window is closed.
Secondary Security Glazing
Magnetic secondary glazing provides both thermal and security benefits. The additional pane of glass makes it significantly harder to break through from outside, and the magnetic seal ensures the secondary panel is firmly secured. For ground-floor Edinburgh tenements, this can be an excellent visual deterrent.
