One way to increase security in your home is by using window locks, latches, bars, or hasps on closed windows. It’s important to know which type of window latch will work best for each window style in your home and what features each lock offers. There are a variety of different locks that can be installed on a window or sliding glass door, with some being more effective than others at keeping intruders out. We also have a great selection of window styles and variations to satisfy your bathroom window privacy ideas.

Window locks are available in dozens of styles and configurations including:

  • Sliding locks
  • Hinge wedge
  • Sash lock
  • Keyed locks
  • Sliding window lock
  • Bolt lock
  • Hinged wedge locks AKA hinged wedge lock
  • Swivel action locks
  • Folding latches
  • Window pin lock
  • Lock pins AKA pin locks w/locking pin
  • Key locks
  • Push locks
  • Handle lock
  • Simple locks

Smart Locks vs Traditional Window locks

Window locks can be divided into two categories: intelligent locks and a traditional window latches. A Smart lock is operated by a keypad or remote control otherwise known as intelligent window opening control devices, and they usually have a sensor that can detect when someone is trying to break in. A traditional window hasp is opened and closed with a key, and they don’t typically have any special features other than keeping the window locked. Which type of window latch you should install depends on your needs and budget. For example, smartphone-operated smart locks are more expensive than a key-operated traditional window hasp, but they can be opened by authorized users who also have smartphones.

Traditional Window Lock

If the door to your home has a locking mechanism that’s easy to operate, a traditional window hasp is a good way to secure your windows. Since a traditional window lock is opened and closed with a key, it requires a bit more work to open them. They’re also more difficult to break into than the most common type of window lock available on the market. For example, a regular window lock can’t be pried open with a crowbar because they’re attached to the frame of the window.

Examples of traditional types of window locks are below:

  • Folding lock
  • Keyed locks
  • Window pin lock
  • Chain lock
  • Hinged wedge lock
  • Ventilating lock
  • Swivel action lock
  • Swivel action lock
  • Push-lock
  • Sliding window locks

Smart Lock

Smart locks are operated by a keypad or remote control. The keypad is usually installed next to the door and allows authorized users to unlock it using numbers or codes that can be changed frequently. For example, if you have an automated security system with sensors on your windows, you might find it easier to use a smart lock so you don’t have to worry about carrying a key with you when you leave the house. An intelligent lock can also be beneficial because they usually have a sensor that can detect when someone is trying to break in. If an intruder tries to force open the door or window while the smart lock is engaged, it will sound an alarm or send a notification to your smartphone.

Which type of window lock you choose depends on your needs and budget. If you’re looking for a more secure option, installing a traditional window lock is a good choice. If you want to be able to open the window without having to carry a key with you, or if you want the convenience of a sensor that detects break-ins, a smart lock is a good option.

Lock Grades

If you’re looking to purchase a window hatch, it’s important that you know what type of hasps are allowed on the windows in your home. There are three grades for locking bars:

  • Grade 1 – Bars must be able to hold a minimum of 100 pounds horizontally or vertically.
  • Grade 2 – Bars must be able to hold a minimum of 60 pounds horizontally or vertically.
  • Grade 3 – Bars must be able to hold a minimum of 30 pounds horizontally or vertically.

Grade 1 lock mechanisms are best for windows in areas like the kitchen and bathroom, where children may be more likely to climb onto a window seat or play around open windows. They’re also an important safety feature for people who live on the ground floor of a multi-story building.

Which Lock Is Best, Factory Locks Or Aftermarket Locks?

Aftermarket hasps is a lock that is not installed at the factory. They’re available in a variety of shapes, sizes, and colors, and they can be installed on most types of windows. Aftermarket latches are typically less expensive than factory latch, but they’re not always as secure. Factory latches are usually made of metal and have a less visible design. For example, factory locks for casement windows are designed to fit inside the window so they’re not as noticeable from the exterior of the home. Though both types of locks can be installed on most types of windows, there are some exceptions.

Which type of lock you choose depends on your needs and budget. Factory locks tend to be more expensive, but they’re also made of higher-quality materials that are well-suited for long-term use. Aftermarket locks are an affordable solution for smaller windows, like sidelights or picture windows.

Keep in mind with aftermarket locks that many times they are less secure than factory locks. This is because factory locks are designed to perfectly fit and secure that exact window. Aftermarket locks could fail for many reasons, including improper installation, poor fitment, or low quality materials.

Some Windows Are Only Compatible With Certain Locks

Certain locks are designed to fit specific types of windows. For example, if you have casement windows, you’ll need to purchase a lock that fits this type of window. These locks attach to the side of the window and can usually be installed with minimal effort.

For other windows, like double-hung or sliding windows, you’ll need a lock that can fit inside the window. This type of lock is less visible from the exterior of the house, and installation usually only requires a screwdriver to screw it in place. Some lock types aren’t compatible and cannot be properly installed. For proper window lock and window installation, always consult with a professional if you want something installed properly. Most companies offer warranties and service guarantees, not just peace of mind due to increased safety and comfort.

Are You Protected Against Storm Damage?

Storm damage is one of the most common reasons homeowners have to replace locks on their windows. If your window hasp isn’t up to the task of protecting your home from a severe storm, you may find yourself replacing it and your expensive double-hung windows sooner than you expected.

A window hasp on your window frame will help protect your home from storm damage, but they’re not always 100% effective. If you live in an area that’s prone to severe storms, it’s a good idea to have a backup plan in place. This could include installing storm shutters or having a friend or family member keep an eye on your home while you’re away.

Why Are Window Locks Important?

Locks are an important part of securing windows in your home. Without them, anyone can open your windows from the outside. While locks are not the only security measure you should take, they are essentially the first line of defense toward an intruder. Many burglars will try to enter a home through an unlocked window, so installing proper window locks can help to deter them from doing so.  In addition, a window hasp can also help to prevent accidents and injuries caused by windows opening unexpectedly.

Installing a window lock is important for many reasons and you should consider your options if you own any of the following kinds of windows:

  • Double-hung windows
  • Sliding windows
  • Awning windows
  • Casement windows
  • Hung windows
  • Replacement windows
  • Horizontal sliding windows
  • Single-hung windows
  • Sliding doors (technically a giant window)
  • Top hung windows
  • Basement windows

What’s the easiest window to break into?

Double-hung windows are the easiest to break into. If you own a double-hung window consider using a bevel window sash lock, candle lock, or half-moon lock on your window frame. You can save a lot of money by installing the right window safety device. All it takes is some research, expertise, a few lag screws to secure your casement window.

How do I decide which window lock is best?

There are a variety of window locks to choose from, so it’s important to select the one that is best suited for your needs. The most common types of window locks are:

Multi-point locking systems: These locks use multiple points of contact to secure the window. They are typically installed on windows that are located high up or that are difficult to reach.

Slam shutters: These shutters automatically close and lock when the window is closed, providing an extra layer of security.

Window pins: These locks use pins to secure the window in place. They are easy to install and can be used on a variety of window types.

Window alarms: These loud alarms sound when the window is opened, alerting you to an intruder and notifying you of the location of the window if it is broken.
