What are the safest window locks?

Window locks are an important part of home security, especially if you have young children. Choosing the right window locks can help prevent falls and keep intruders out. But with so many options on the market, how do you know which ones are the safest?

In this article, we’ll go over the different types of window locks, factors to consider when choosing locks, and provide recommendations for the safest window lock options for various needs. We’ll also answer common questions about installing and using window locks effectively.

Types of Window Locks

There are a few main types of window locks to choose from:

Sash Locks

Sash locks, also called sash locks or sash window locks, are fitted on the upper and lower sashes of the window to lock them together. They are the most common type of window lock. Depending on the style, they use a latch, threaded rod, or spring-loaded bullets to secure the windows.

Ventilation Locks

Ventilation locks allow you to lock the window while leaving a small gap for ventilation. They can be used together with sash locks for security with airflow.

Restrictor Locks

Restrictor locks only allow the window to open a certain amount, usually a few inches. They are useful for preventing children from opening the window too far and falling out.

Entry Control Locks

Entry control locks allow you to lock and unlock the window from the inside while preventing access from the outside. This makes them ideal for ground floor windows.

Security Bars

Security bars are metal bars that can be installed on the outside of windows to prevent forced entry. They provide high security but also negatively impact aesthetics.

Factors to Consider When Choosing Window Locks

Here are some important factors to keep in mind when selecting window locks:

Window Type

The type of window you have affects the styles of locks available. Be sure to get a lock designed for your specific window type.

Location of the Window

Ground floor and easily accessible windows require a higher level of security. Second story or difficult to reach windows may only need basic sash locks.

Preventing Access by Children

If you have young children, restrictor locks and locks with protective covers can help prevent kids from opening the windows.

Allowing Ventilation

If you want fresh air from the window, look for ventilation locks that provide both security and airflow.

Aesthetics

Some window locks are more visually obtrusive than others. Make sure you are comfortable with the appearance of the lock.

Budget

Window lock prices range from $5 to over $50 depending on the material, design, quality and security level. Determine how much you want to invest.
