Why I Swear By Window Stoppers for Sliding Windows

As a homeowner, I have always been concerned about the safety and security of my family and our belongings. One aspect that often gets overlooked is the security of our windows, especially the sliding ones. That’s when I discovered the importance of window stoppers for sliding windows.

Firstly, window stoppers provide an added layer of security against potential break-ins. Sliding windows are particularly vulnerable as they can easily be lifted off their tracks from the outside. With a window stopper in place, it becomes almost impossible for an intruder to open the window from the outside.

Secondly, window stoppers prevent accidents and injuries, especially in households with young children or pets. Sliding windows can be dangerous if left open and unattended as they can easily slam shut or get pushed open by strong winds. A window stopper acts as a barrier and prevents any unfortunate accidents from occurring.

Moreover, window stoppers also help with temperature control in our homes. In summer months, we often want to leave our windows slightly open to let fresh air in. However, without a stopper, the window can easily slide open completely and let hot air in, defeating the purpose of ventilation. With

My Buying Guide on ‘Window Stopper For Sliding Windows’

As a homeowner, I understand the importance of having secure and functional sliding windows. However, I also know that sometimes these windows can be difficult to keep in place. That’s where a window stopper for sliding windows comes in handy. Through my own personal experience and research, I have compiled this buying guide to help you find the perfect window stopper for your sliding windows.

What is a window stopper for sliding windows?

A window stopper is a device that is used to keep your sliding windows in place. It is typically placed on the bottom track of the window and prevents the window from moving or being lifted out of its frame. This not only provides added security but also helps to prevent drafts and keeps your windows closed during windy weather.

Things to consider before buying a window stopper:

1. Window type: Before purchasing a window stopper, it is important to consider the type of sliding window you have. Different types of windows may require different types of stoppers, so make sure to measure and understand your window type before making a purchase.

2. Material: Window stoppers are available in various materials such as metal, plastic, and rubber. Each material has its own advantages and disadvantages, so it’s important to choose one that will best suit your needs.

3. Size: The size of the window stopper should be compatible with your sliding windows. Make sure to measure the width and height of your windows before purchasing to ensure a proper fit.

4. Security level: Some window stoppers are designed specifically for added security while others are more suitable for preventing drafts. Consider how much security you need and choose a suitable option accordingly.

5. Ease of installation: Look for a window stopper that is easy to install without the need for any special tools or equipment. This will save you time and effort during installation.

Types of Window Stoppers:

1. Wedge Stopper: These are small triangular-shaped pieces made from either rubber or plastic that can be easily wedged into the bottom track of your sliding window to prevent it from opening or closing.

2. Track Stopper: These are long bars with adjustable lengths that can be placed in the bottom track of your sliding window to keep it from moving back and forth.

3. Hinged Wedge Stopper: This type of stopper has two hinged pieces that can be adjusted to fit different sized windows and provide added security by locking onto both sides of the frame.

4. Security Pin Locks: These locks are inserted into holes drilled into both sides of the top track of your sliding window, preventing it from being lifted out.

Tips for using a window stopper:

1. Make sure to clean the bottom track of your sliding window before installing the stopper as dirt or debris may affect its performance.
