1. Multi-Point Security Locking Systems

Multi-point locking systems can be a very effective way to secure your windows and doors. These mechanisms allow a single lever handle to engage multiple locking points simultaneously. Where the correct manufacturing practices are adopted to ensure adequate tear out strength of the screw fixings securing the multi point locking to the frame  these can provide a robust barrier against forced entry. For replacement double glazed windows, features such as dual-cam mushroom-headed multi-point locking and espagnolette locking with shoot bolts are popular choices.

  • Espagnolette Locking: espagnolette locking involves a metal strip rebated into the edges of the opening parts of the window carrying projecting bolts that slide into keeper blocks when the handle is turned.
  • Dual-Cam Mushroom-Headed Locks: This system uses multiple pairs of bolts shaped like mushrooms that engage into the keepers on the window frame. The mushroom shape prevents the bolts from being lifted out of the keeper slots  offering resistance to forced entry.

2. Key Locking Handles for Windows

Key locking handles are a beneficial security feature for new double glazed windows. These handles allow homeowners to lock their windows securely with a key, preventing the handle to be manipulated to gain unauthorized access. The ability to lock windows adds a layer of protection, especially for ground floor windows or those in easily accessible areas. Key locking handles are beneficial for maintaining security on windows with night vent locking where the windows can be secured with a circa 10-12mm air gap for ventilation.

3. Anti-Jemmy Hinges

Anti-jemmy hinges can be fitted in modern double glazing security. These hinges are designed to resist forced entry attempts by making it difficult for intruders to pry the window open. Their robust construction and strategic placement help to ensure that your windows remain firmly secured.

4. High-Security Locking System Features for Doors

Double glazed doors require high security locking systems to ensure maximum security. For uPVC and Composite GRP double glazed doors, several key features enhance their resistance to tampering and forced entry.

  • Lever Handle Operated Espagnolette Multi-Point Locking: This system uses a lever handle to engage multiple locking points that can include combinations of vertical shoot-bolts, drop bolts, dead bolts and hook bolts and a latch bolt. The inclusion of hook-bolts adds a layer of security making it difficult for the door to be forced open.
  • Hook bolts are an integral part of high-security multi-point locking systems for doors. These heavy duty bolts extend into the door frame when the door is locked, hooking into place to prevent the door from being lifted or pried open. Their hook shape provides enhanced resistance to forced entry, making them an excellent choice for securing double glazed doors.
  • Epicentric Compression Adjustable Drop Bolts: These bolts offer enhanced weather resistance and contribute additional security by applying consistent pressure across the height of the door ensuring that the door remains tightly closed.
