how to measure for storm windows

Installing storm windows is a fantastic way to improve your home's energy efficiency, reduce noise pollution, and enhance its overall comfort. But before you even think about ordering, accurate measurements are crucial. A poorly measured storm window will lead to frustration, wasted money, and a less-than-perfect fit. This guide will walk you through the process, ensuring you get the perfect storm window every time.

What Tools Do I Need to Measure for Storm Windows?

Before you start, gather the following tools:

  • Measuring Tape: A steel tape measure is ideal for accuracy.
  • Pencil: For marking measurements directly onto the window frame.
  • Notebook: To record your measurements.
  • Level: Ensure accurate measurements, especially for windows that aren't perfectly square.
  • Calculator: Helpful for calculating the total dimensions.

How to Measure the Existing Window Frame: A Step-by-Step Guide

Measuring for storm windows involves taking several key measurements to ensure a snug fit. Here's a breakdown of the process:

  1. Clean the Window Frame: Remove any dirt, debris, or paint that might interfere with accurate measurements.

  2. Measure the Width: Measure the width of the window frame at three points: the top, middle, and bottom. Record the narrowest measurement. This is crucial, as the storm window needs to fit inside the existing frame.

  3. Measure the Height: Similarly, measure the height at three points: left, center, and right. Again, record the narrowest measurement.

  4. Measure the Depth (Frame Thickness): This is often overlooked but essential. Measure the depth of the window frame where the storm window will sit. This determines the thickness of the necessary frame or mounting hardware for your storm window.

  5. Check for Squareness: Use a level to ensure that your window frame is square. If it's not perfectly square, note any discrepancies in your measurements. This can inform the installer of any adjustments they might need to make.

  6. Record All Measurements: Write down all your measurements clearly, labeling each one (width, height, depth). Include the unit of measurement (inches or centimeters).

  7. Account for Installation Allowance (if necessary): Some storm window installation methods might require additional allowance for the mounting hardware. Check the manufacturer's instructions or consult with a professional installer for specific guidance.

What are the Different Types of Storm Windows?

Understanding the types of storm windows available will help you determine the most appropriate measurement approach. Common types include:

  • Full-Frame Storm Windows: These completely cover the existing window frame. The measurements should be taken precisely as described above, ensuring they fit inside the frame.
  • Insert Storm Windows: These fit inside the existing window frame, often using a glazing method. Accurate measurements are crucial for a precise fit.
  • Interior/Exterior Storm Windows: These can be fitted either on the inside or outside of your window frame, requiring specific measurements depending on the installation location. Always consult manufacturer's instructions.

How Do I Measure for Replacement Windows vs. Storm Windows?

This is a common question. Replacement windows entirely replace your existing window, while storm windows fit over or inside your existing window. Therefore, the measurements are completely different:

  • Replacement windows: Require measuring the exterior dimensions of the window frame itself (where the window is placed into the wall), including the rough opening.
  • Storm windows: Measure the interior dimensions of the existing window frame, as the storm window needs to fit inside the existing window frame.

What If My Windows Are Not Standard Sizes?

Many older homes have uniquely sized windows. Don't worry! Most manufacturers can create custom-sized storm windows. However, accurate measurements are even more critical in these situations.

Conclusion: Accuracy is Key

Getting the right measurements for your storm windows is the foundation for a successful installation. Take your time, double-check your work, and don't hesitate to consult a professional window installer if you have any doubts. A properly measured and installed storm window will provide years of enhanced comfort and energy savings.
