Storm windows provide an extra layer of protection for your home against harsh weather conditions. They help improve energy efficiency, reduce noise, and extend the life of your primary windows. Properly measuring your windows for storm windows is crucial for ensuring a perfect fit for replacement hardware and optimal performance. Here’s a step-by-step guide on how to measure storm windows accurately.

Tools You Will Need:

• Measuring tape (preferably a steel one for accuracy)
• Notepad and pen or a digital device for recording measurements
• Ladder (if measuring upper-story windows)
• Assistant (optional but helpful)

Step-by-Step Guide

1. Measure the Window Width

Start by measuring the width of the window. Measure at three different points: the top, middle, and bottom. This helps account for any irregularities in the window frame.

- Top Width: Measure from the inside edge of the window frame on the left to the inside edge on the right.

- Middle Width: Measure the same way, but in the middle of the window.

- Bottom Width: Measure from left to right at the bottom of the window frame.

Record all three measurements and note the smallest one. This will be the width you use for ordering your storm windows if you’re getting brand new replacement windows.

2. Measure the Window Height

Next, measure the height of the window in three different places: the left side, the middle, and the right side.

- Left Height: Measure from the left inside edge of the top of the window frame to the left inside edge of the bottom frame.

- Middle Height: Measure from top to bottom in the middle of the window.

- Right Height: Measure from the top to the bottom on the right side of the window frame.

Again, record all three measurements and use the smallest one for ordering purposes.

3. Check the Depth of the Window Frame

The depth of the window frame is crucial to ensure that the storm window fits properly without obstructing the primary window. Measure the depth of the window frame from the inside edge to the outside edge. This measurement can also be vital when ordering window balances or sash stops.

4. Double-Check Your Measurements

Before finalizing your measurements, double-check each one. Accurate measurements are essential for a proper fit, and mistakes can lead to additional costs and delays.

5. Consider the Type of Storm Window

Different types of storm windows may have specific measurement requirements. For instance, interior storm windows might need slightly different measurements compared to exterior ones. Consult the manufacturer’s guidelines for any specific instructions related to the type of storm window you are purchasing.

Tips for Accurate Measurements

• Always measure from the inside of the window frame.
• Use a steel measuring tape for precision.
• If you have multiple windows of the same size, measure each one individually to account for any variations.
• Have someone assist you if the windows are large or located in hard-to-reach places.

Why Accurate Measurements Matter

Properly measured storm windows ensure a tight seal, which is essential for maximizing energy efficiency and protection. Poorly fitting storm windows can lead to drafts, increased energy costs, and reduced effectiveness in protecting your home from the elements. For extra efficiency and protection, these measurements can also help when ordering weatherstripping to further seal your storm windows.

Conclusion

Measuring storm windows may seem daunting, but with the right tools and a systematic approach, it can be done accurately and efficiently. By following this guide, you can ensure that your storm windows fit perfectly, providing optimal performance and protection for your home.
