Sash windows are traditional details of many an era property within the UK, admired for their elegant proportions and period charm. But are sash windows safe? The fact is that old sash windows were not exactly designed with contemporary security issues at heart. Yet, with proper modernisations in place, sash windows can be extremely safe, without forfeiting their heritage charm.
Since the year 2002, burglaries in the UK have dropped by about 70%, which is an encouraging improvement in security, but also highlights evolving police focus on certain crimes. These days, more focus is placed on other kinds of offences, like cybercrime, meaning any security measure you can take yourself still makes a big difference.
Throughout this guide, we will be discussing how to secure sash windows effectively, explaining what makes a secure sash window, and helping you decide when replacement or repair is the best solution.
Are Sash Windows Secure?
The question “Are sash windows safe?” is one that tends to come up on old houses, and it’s an understandable concern. Many traditional and ageing sash windows have plain latches, single glazing, and decayed frames, so they’re more vulnerable to burglars. But it’s worth making a distinction between original sash windows and those that have been upgraded or modernised.
Up-to-date sash windows, especially those installed by professional companies like Wandsworth Sash Windows, boast robust security measures that meet modern safety standards without sacrificing traditional appearances. By integrating the right upgrades, sash windows are as secure as new frames.
How to Secure Sash Windows Effectively
1. Sash Window Locks and Stops
One of the simplest ways to make sash windows secure is through the addition or replacement of lockable sash fasteners. These are unobtrusive metal components that lock the top and bottom sashes shut when closed. They deter attempts to open the sashes from the outside, especially when combined with double screws or sash stops, which restrict the extent to which the window may be opened.
Sash stops are particularly useful for providing ventilation without compromising security, ideal for warm evenings when you want air movement but also reassurance. Some of these security features can be fitted into existing frames without their aesthetic appeal being compromised.
2. Upgrade to Toughened or Laminated Double Glazing
Single-glazed windows are not only less energy efficient, they’re also more prone to breaking. Switching to laminated or toughened double glazing makes a significant difference in insulation and security. Upgraded glass on sash windows has the following benefits, among others:
- Toughened glass is five times stronger than regular glazing.
- Laminated glass has a tough plastic interlayer that stops the glass from shattering into pieces if it is broken, so forced entry is much harder.
Not only does this strengthen your home’s defences, but it also provides noise suppression and improved energy efficiency. And if you live in a conservation area, Wandsworth Sash Windows offers slimline double glazing solutions that meet heritage specifications while increasing security.
3. Reinforce or Replace the Frame
Even with strong locks and solid glazing, your windows will remain vulnerable if the timber frame is rotten or damaged. If your sash windows are rotten, they have gaps, or they are simply worn out, it’s maybe time to reinforce or replace them entirely.
Wandsworth Sash Windows’ bespoke or professionally restored timber sash windows can be fitted with built-in reinforcements, offering increased protection against impact and attempted forced entry. These additions are subtly incorporated to maintain the original aesthetic of your home.
4. Fit Window Sensors and Alarms for Extra Security
For an added layer of security, especially when you’re away from home, consider installing window sensors or alarms. These discreet devices detect movement or opening and can trigger alerts to your phone or smart home system.
They can be painted to match the frame or hidden within the sash, ensuring your window’s classic appearance is preserved while boosting security.
5. Be Strategic With Ventilation Locks
Vent locks are an excellent balance between security and ventilation. These clever devices allow your sash window to open slightly (typically a few inches), where air can pass through but someone cannot open it any wider from the outside.
They’re especially useful on ground-floor windows or children’s bedrooms where ventilation and security must go together.
Are Upgraded Sash Windows Resistant to Forced Entry?
Yes, if implemented correctly, sash windows are actually very secure. Wandsworth Sash Windows utilises the most modern locking mechanisms and glazing techniques that greatly increase resistance to forced entry.
When Is Full Replacement Ideal?
All sash windows are not always upgrade-worthy. If you notice any of the following issues, it may be time to consider a full replacement set of sash windows:
- Rotten or soft wood
- Rattling single glazing
- Large gaps admitting draughts
- Sticking or loose sashes
- No locks or catches in place
