How To Secure Windows With Plywood

When it comes to securing windows, one often overlooked solution is using plywood. Plywood is not just for construction projects; it can be a cost-effective and simple way to add an extra layer of protection to your windows. With its strength and durability, plywood can help deter intruders and reinforce your home's security. So why not consider securing your windows with plywood?

Plywood has a long history of being used for various purposes, and securing windows is no exception. It provides a barrier that can help withstand impact, making it harder for potential intruders to break in. Moreover, according to the FBI, about 30% of burglars enter a home through an unlocked or open window. By securing your windows with plywood, you not only make it more difficult for intruders to gain access but also decrease the chances of becoming a target in the first place. Plywood is an affordable and accessible solution that can enhance the security of your windows.

Why Secure Windows with Plywood?

When it comes to home security, windows are often the most vulnerable entry points. In the event of extreme weather conditions or the unfortunate occurrence of a break-in, securing windows becomes crucial. Plywood is an affordable and effective solution that can provide temporary reinforcement to your windows and protect your home. By understanding how to properly secure windows with plywood, you can enhance the safety and security of your property.

Choosing the Right Plywood

Before you jump into securing your windows with plywood, it's important to choose the right type of plywood for the job. Look for exterior-grade plywood, such as CDX or BC grade, as they are more resistant to moisture and weather damage. The thickness of the plywood should depend on the size of your windows. A minimum of 5/8 inch plywood is recommended for standard-sized windows, while larger or more vulnerable windows may require thicker plywood.

Additionally, consider the aesthetics of your home. If you plan to paint the plywood, opt for a smooth finish. However, if you prefer the natural look, a rougher plywood surface may be more suitable. Remember, the primary purpose of the plywood is security, so choose a type that meets your needs while ensuring it is durable and strong enough to withstand the elements.

It's also essential to take accurate measurements of your windows before purchasing the plywood. Measure the height and width of each window, allowing for a small gap around the edges to accommodate the installation process.

Preparing the Windows

Prior to installing the plywood, you should thoroughly clean and prep your windows. Remove any dirt, debris, or loose paint from the window frames to ensure a secure and proper fit for the plywood. This step is crucial as it allows for better adhesion and reduces the risk of damage to the windows or the plywood itself.

If there are screens or storm windows in place, remove them before installing the plywood. Screens and storm windows can interfere with the installation process and compromise the effectiveness of the reinforcement. Once the windows are prepped and ready, you can proceed with the installation.

It's worth mentioning that securing windows with plywood is a temporary solution, typically used during extreme weather events or when you're away from home for an extended period. For long-term window security, consider investing in impact-resistant windows or installing window security film.

Installing the Plywood

Now that you have the right plywood and prepared your windows, it's time to start the installation process. Follow these steps to securely install the plywood:

  • Measure and mark the dimensions of each window on the plywood.
  • Using a circular saw or table saw, cut the plywood to the measured dimensions.
  • Once the plywood pieces are cut, sand down any rough edges to ensure a proper fit.
  • Place the plywood over the window, ensuring it covers the entire opening.
  • Use screws or nails to secure the plywood to the window frame. Place them approximately every 12 inches around the edges and spaced evenly across the center.

It's important to note that the installation process may vary depending on the type and design of your windows. If you're unsure or need assistance, consult with a professional or refer to the manufacturer's guidelines for your specific window type.

Sealing the Gaps

After installing the plywood, it's crucial to seal any gaps or openings to enhance security and prevent drafts. You can use caulk or weatherstripping around the perimeter of the plywood to create a better seal. This step helps to keep out moisture, pests, and unwanted air infiltration.

Additionally, consider applying a waterproof sealant to the plywood itself. This extra layer of protection can further enhance its durability and resistance to the elements. Regularly inspect the plywood for any signs of damage or decay, and make necessary repairs or replacements as needed.

Maintenance and Removal

To ensure the effectiveness of your window security, it's essential to regularly maintain and inspect the plywood. Check for any visible damage, rot, or signs of wear, and promptly address these issues. Replace any damaged plywood to maintain the integrity of your window reinforcement.

When the temporary need for window security has passed, carefully remove the plywood. Start by unscrewing or removing the nails that secure it to the window frame. Use caution when handling the plywood to avoid injury or damage to the windows. Store the plywood in a safe and dry location for future use.

Enhancing Home Security

In addition to securing windows with plywood, there are other measures you can take to enhance overall home security:

1. Install Window Security Film

Window security film is a transparent, adhesive film that reinforces the glass of your windows, making them more resistant to shattering. It acts as a protective barrier against forced entry, extreme weather events, and even UV rays. Window security film can be a valuable addition to your home security system, providing an extra layer of protection.

The film is typically installed on the inside of the window and can be purchased in different levels of thickness and strength. It is virtually invisible and does not significantly impact the appearance of your windows.

Installation of window security film requires precision to ensure a bubble-free and smooth finish. If you're not confident in your ability to install it yourself, consider hiring a professional.

2. Reinforce Window Frames and Locks

While plywood and window security film are effective temporary measures, reinforcing your window frames and locks is a more permanent solution. Ensure that all window frames are secure and in good condition. Consider upgrading to reinforced or impact-resistant window frames, which are designed to withstand high-force impacts.

Additionally, check the condition and functionality of your window locks. Reinforce them, if necessary, with additional security devices such as window bars, sash locks, or key-operated locks. These measures can greatly enhance the security of your windows and deter potential intruders.

3. Install a Home Security System

A comprehensive home security system can provide you with peace of mind and an added layer of protection for your windows and overall property. Install security cameras around your home, including near windows, to monitor any suspicious activity.

You can also connect your windows to a sensor system that detects any attempts at forced entry. These sensors can trigger alarms and notify you or a security service provider of any potential breaches.

4. Maintain Visibility

Keep bushes, trees, and any other hindrances trimmed and away from your windows. Maintaining visibility around your property reduces potential hiding spots for intruders. Adequate lighting, both indoors and outdoors, can also deter criminals.

If your windows are located in an area with high foot traffic or potential visibility from neighbors, it can serve as an effective deterrent. Criminals are more likely to target homes with easy access and minimal risk of being caught.

By securing your windows with plywood and implementing additional security measures, you can significantly reduce the risk of break-ins and better protect your home. Remember to regularly assess your home's security needs and make necessary adjustments to ensure the safety and peace of mind for you and your family.
