Window Locks & Latches

Window locks and latches are hardware components designed to secure windows and prevent unauthorized access. They come in various types, including sash locks, cam locks, sliding locks, and keyed locks, and can be installed on different types of windows, such as casement, sliding, double-hung, and awning.

Window locks and latches remain relevant today as they are essential for enhancing security, especially in urban areas or homes with ground-level windows. They also promote energy efficiency by ensuring proper sealing and insulation, reducing heat loss or gain. Modern window locks and latches incorporate advanced materials, technology, and design, offering improved durability, ease of use, and aesthetic appeal.

Window locks and latches date back to ancient civilizations, where simple wooden or metal bars were used to secure windows against intruders. During the Middle Ages and Renaissance, elaborate iron grilles and lattice patterns emerged, serving both decorative and protective functions. With the advent of modern windows in the 19th century, various locking mechanisms and latches were developed, ranging from simple hooks and eyes to complex multi-point locking systems. Today, window locks and latches remain an essential component of window hardware, providing security, energy efficiency, and aesthetics for homes and buildings.

What causes a window latch not to close properly?

A window latch may not close properly due to various factors, including misalignment, wear and tear, or damage to the latch or frame. Dirt or debris buildup, warped or damaged window frames, or loose screws may also affect latch operation. Proper maintenance, such as regular cleaning and lubrication, or professional repairs, can often restore a faulty latch to optimal function.

Are window latches secure?

Window latches can be secure depending on the type and quality of the latch. Basic latch designs, such as simple hooks or snap locks, may be easily bypassed by determined intruders. Multi-point locking systems, keyed locks, or smart locks offer greater security and deterrents against forced entry. Proper installation, maintenance, and use of latches can further enhance their effectiveness and ensure optimal performance.

What does latch protection mean?

Latch protection refers to measures taken to prevent latch bypass or tampering, enhancing window security. Common methods include installing metal plates, reinforcing the latch or frame with extra screws, or using specialized security hardware, such as latch guards or tamper-resistant screws. Latch protection can improve the effectiveness of a window latch and deter unauthorized access, increasing safety and peace of mind.
