Storm windows are a valuable addition to any home, offering an extra layer of protection against the elements and improving insulation. Over time, however, the glass in these windows can become damaged or broken, necessitating a replacement. Whether you’re dealing with a crack, a completely shattered pane, or just old, inefficient glass, knowing how to replace a storm window glass is a useful skill for any homeowner. In this guide, we will provide a step-by-step walkthrough of the replacement process, ensuring you can maintain the integrity and functionality of your storm windows.

What are Storm Windows?

Storm windows are secondary windows that are installed either outside or inside the main windows of a house. They serve as an additional barrier against the elements, reducing heat loss and protecting the primary windows from wind, rain, and snow. By creating an insulating layer of air between the storm window and the primary window, they help to enhance energy efficiency and comfort within the home. Storm windows can be particularly beneficial in regions that experience extreme weather conditions, as they provide extra protection against the elements.

Types of Glass for Storm Windows

Choosing the right type of glass for your storm windows is crucial for maximizing their benefits. There are several types of glass to consider, each with its own advantages and disadvantages.

Single Pane vs. Double Pane

Single Pane: This is a single layer of glass, which is typically less expensive but offers minimal insulation. Single-pane glass is suitable for areas with mild climates but may not be sufficient for regions with extreme weather.
Double Pane: Double-pane glass consists of two layers of glass with an air or gas-filled space in between. This design significantly improves insulation and energy efficiency by reducing heat transfer. Double-pane windows are ideal for homes in areas with harsh winters or hot summers.

Tempered Glass

Tempered glass is treated with heat to increase its strength compared to regular glass. One of its key features is that it breaks into small, blunt pieces rather than sharp shards, reducing the risk of injury. This makes tempered glass a safer option, especially for homes with children or pets.

Laminated Glass

Two layers of glass are combined with a plastic layer to create laminated glass.This construction ensures that the glass holds together when shattered, providing enhanced security and sound insulation. Laminated glass is often used in areas where safety and noise reduction are priorities.

Tools and Materials Needed to Replace a Storm Window Glass

Before you begin the process of replacing your storm window glass, it’s important to gather all the necessary tools and materials. Having everything ready will make the job smoother and more efficient.

Essential Tools

To replace a storm window glass, you will need the following tools:

Screwdriver: A flathead or Phillips screwdriver, depending on the type of screws used in your window frame, will be essential for removing and reinstalling the window.
Utility Knife: A sharp utility knife will help you cut through old glazing compounds and putty.
Putty Knife: This tool is useful for scraping off old putty and smoothing new glazing compounds.
Glass Cutter: If you need to cut the new glass yourself, a glass cutter will be necessary.
Gloves and Safety Glasses: Always wear protective gear to safeguard against cuts from glass shards.
Measuring Tape: Accurate measurements are crucial for cutting the new glass to the correct size.

Necessary Materials

You’ll also need these materials:

Replacement Glass: Ensure that the new glass is cut to the correct size before beginning the installation.
Glazing Compound or Putty: This material is used to seal the glass in place and provide a weather-tight finish.
Glazing Points: These small metal clips hold the glass securely in the frame while the glazing compound sets.
Sandpaper: Use sandpaper to smooth any rough edges on the window frame before installing the new glass.

Step-by-Step Guide to Replacing Storm Window Glass

Replacing a storm window glass might seem daunting, but by following these detailed steps, you can accomplish the task efficiently and safely.

Step 1: Remove the Storm Window

The first step in how to replace a storm window glass is to remove the storm window from its frame. This process involves a few careful steps:

Locate the Screws: Identify the screws or fasteners that are holding the storm window in place. These are usually located along the sides of the window frame.
Unscrew Carefully: Use the appropriate screwdriver to remove the screws. Be sure to keep the screws in a safe place, as you will need them for reinstallation.
Lift Out the Window: Once the screws are removed, gently lift the window out of the frame. If the window is large or heavy, consider asking someone to help you avoid accidents or damage.

Step 2: Remove the Broken Glass

With the storm window removed, the next step is to get rid of the broken glass. This step requires careful handling to prevent injury.

Wear Protection: Before you start, put on gloves and safety glasses to protect yourself from sharp glass shards.
Remove Old Glazing: Use a utility knife and putty knife to carefully scrape off the old glazing compound or putty that is holding the broken glass in place.
Extract the Glass: Carefully remove the broken glass pieces from the frame. If the glass is shattered, you may need to remove it piece by piece. Dispose of the broken glass safely in a sturdy container.

Step 3: Accurately Measure and Cut Your New Glass

Accurate measurement is key in how to replace a storm window glass. Follow these steps to ensure the new glass fits perfectly.

Measure the Opening: Use a measuring tape to measure the height and width of the window opening. Measure twice to ensure accuracy.
Cut the Glass: If you are cutting the glass yourself, use a glass cutter to score the glass along the measured lines. Apply steady pressure and snap the glass along the score line. If you prefer, you can have a professional cut the glass to the size you prefer.

Step 4: Install the New Glass

With the new glass cut to size, it’s time to install it into the frame.

Apply Glazing Compound: Spread a thin layer of glazing compound around the inside edges of the window frame using a putty knife.
Set the Glass: Carefully place the new glass into the frame, pressing it gently into the glazing compound to ensure a snug fit.
Secure with Glazing Points: Insert glazing points every few inches along the edges of the glass. These small metal clips hold the glass securely in place while the glazing compound sets.
Apply More Compound: Apply another layer of glazing compound over the edges of the glass, smoothing it out with the putty knife. Ensure that the compound seals all gaps to prevent air and moisture from entering.

Step 5: Reinstall the Storm Window

Finally, reinstall the storm window back into its frame.

Position the Window: Carefully place the window back into the frame.
Secure with Screws: Reinsert the screws that you removed earlier to secure the window in place.
Check for Stability: Ensure the window is stable, and the glass is securely fitted. Perform a final check to make sure there are no gaps or loose areas.

Maintenance Tips for Storm Window Glass

Replacing storm window glass is just one part of maintaining your windows. Proper maintenance can significantly extend the life of your storm windows. Use these guidelines to keep them well-maintained:

Clean Regularly: Regularly clean the glass and frames to prevent dirt and grime buildup. Use a mild detergent and water for cleaning, and avoid harsh chemicals that can damage the glass or frame.
Inspect for Damage: Periodically inspect the glass and frames for any signs of damage, such as cracks, chips, or warping. Identifying problems early can help avoid more severe damage.
Lubricate Moving Parts: Lubricate the hinges, locks, and other moving parts of the storm windows to ensure smooth operation. To achieve the best results, use a silicone-based lubricant.
