Inward opening casement windows are a popular choice in both residential and commercial settings due to their elegant appearance and ease of cleaning. However, when it comes to home security, they can present unique challenges. Ensuring these windows are properly secured is essential to protect your property. In this guide, we will explore how to secure inward opening casement windows using the right fittings, including recommendations for the best products and expert installation tips.

Understanding the Security Risks of Inward Opening Casement Windows


Unlike outward opening windows that are harder to manipulate from the outside, inward opening casement windows can be more accessible to intruders, especially if they are left unlocked or fitted with substandard hardware. Common vulnerabilities include:

  • Weak or old locking systems that are easy to force open.
  • Poor-quality window handles that can be easily broken or removed.
  • A lack of secondary security features like restrictors or alarms.

Understanding these weaknesses helps in choosing the right security upgrades.

 

Best Security Fittings for Inward Opening Casement Windows
Upgrading your fittings is the most effective way to secure inward opening casement windows. Here are the most important components to consider:

 

Locking Mechanisms
High-quality locks are essential. For inward opening windows, consider:

  • Multipoint locking systems: These locks engage at multiple points along the window frame, offering superior resistance against force.
  • Espagnolette bolts: Common in European-style windows, these provide strong locking when operated by a handle.
  • Window shoot bolts: Often installed at the top and bottom of the sash, they prevent the window from being pried open.
  • Key-operated locks: Ideal for added security, especially on ground-floor or accessible windows.

Ensure all locking components are made from corrosion-resistant materials such as stainless steel or brass.

 

Reinforced Window Handles
Handles are not just for operating the window; they also serve as an integral part of the locking system. Consider:

  • Locking window handles: These handles feature built-in key locks that prevent the handle from being turned.
  • Heavy-duty construction: Opt for solid metal handles with concealed fixings to deter tampering.
  • Child-safe locks: If you have young children, look for handles with built-in child safety catches.

 

Additional Security Features
Enhance protection further with these additional measures:

  • Window restrictors: Limit how far the window can open, useful for ventilation without compromising security.
  • Security film: Applied to the glass to hold it together if smashed.
  • Reinforced hinges: Use security hinges with non-removable pins to prevent the window from being lifted off.
  • Contact sensors or alarms: Integrate with a home security system to detect when a window is opened unexpectedly.

Installation Tips for Maximum Security
Even the best hardware will underperform if not installed correctly. Here are some expert tips:

  • Follow manufacturer guidelines: Each fitting may have unique installation instructions.
  • Secure into solid material: Fix locks and handles into the window's main frame or reinforced sections.
  • Use appropriate fixings: Screws should be long enough to anchor fittings securely, especially in timber or uPVC frames.
  • Professional installation: If you're unsure, hire a qualified installer. A poorly fitted lock can be as bad as no lock at all.
  • Regular maintenance: Clean and lubricate moving parts, and check for loose fittings periodically.
