How Secure Are Your Windows? A Glazier's Guide to Window Security

Window security is often overlooked until a break-in makes it urgently relevant. The good news is that upgrading the security of your windows rarely means replacing them entirely — targeted improvements to glass and locking hardware can dramatically reduce your vulnerability.

What This Guide Covers

• BS 7950 is the UK standard for enhanced window security — look for this on replacement frames
• Laminated glass is significantly harder to break through than standard float or toughened glass
• Multi-point locking systems on uPVC and aluminium frames are standard — check yours work correctly
• Sash windows are particularly vulnerable — security restrictors and sash locks are cheap and effective
• Ground-floor windows and those accessed from flat roofs are highest priority for upgrades
