Casement Fasteners:
- Hook & Plate Fasteners: Traditional and often used in period properties. These have a hook that catches onto a plate to hold the window closed.
- Espagnolette Fasteners: More modern, offering higher security. They operate a multi-point locking mechanism along the edge of the window.
- Wedge Fasteners: Simple and effective, these use a wedge that tightens against the frame to secure the window.
Sash Window Fasteners:
- Fitch Fasteners: A popular choice for sash windows, featuring a rotating arm that fits into a catch to lock the window.
- Cam And Hook Locks: These are used in sliding windows, where a cam mechanism locks the window into place when turned.
- Quadrant Fasteners: These have a decorative look, suitable for period sash windows, and use a quadrant arm to secure the window.
- Sash Stops: These are secondary security devices that prevent the window from opening beyond a certain point.
Materials
- Brass: Common in high-quality fittings for durability and strength.
- Black Iron: Often used in cottages and rustic settings, providing a robust and traditional look.
- Zinc Alloy: Often used in the manufacture of low-cost window fittings.
Security Features
- Locking Mechanisms: Many modern window fasteners include discrete locks that allow locking with a hex key, providing an extra layer of security.
- Multi-Point Locking: Found in espagnolette fasteners, these lock at multiple points along the window frame, enhancing security.
- Child Safety: Some fasteners integrate a ventilation locking point to allow the widow to lock without allowing a full open position.
Aesthetic Considerations
- Period-Appropriate Styles: For heritage and period properties, selecting fasteners that match the historical style of the window is important.
- Contemporary Designs: Modern homes may opt for sleek, minimalistic fasteners that blend seamlessly with the window design.
- Finish Matching: Ensuring the finish of the fastener matches other hardware (like handles and hinges) for a cohesive look.
Installation and Maintenance
- Professional Installation: Proper installation is important for both security and functionality.
- Regular Maintenance: Keeping the fasteners clean and lubricated ensures smooth operation and longevity. Regular checks for any signs of wear or damage are also important.
Choosing the Right Fastener
- Window Type: Ensure the fastener is designed for the specific type of window (casement, sash, sliding).
- Security Needs: Consider the level of security required. High-risk areas may need more robust locking mechanisms.
- Aesthetic Preferences: Choose a style and finish that complements the overall design of the property.
