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 comfort. However, accurate measurements are crucial for a perfect fit. Getting it wrong can lead to gaps, drafts, and ultimately, a less effective storm window system. This comprehensive guide will walk you through the precise steps for measuring your windows for new storm windows, ensuring a snug and efficient installation.

What Tools Do I Need to Measure for Storm Windows?

Before you begin, gather the following tools:

  • Measuring Tape: A steel tape measure is ideal for accuracy. Avoid flexible cloth tapes, as they can stretch and lead to inaccurate measurements.
  • Pencil: For marking your measurements on a notepad.
  • Notepad: To record your measurements for each window.
  • Level: To ensure your measurements are taken on a perfectly level surface. Even slight inconsistencies can affect the final fit.
  • Camera (Optional): Taking photos of your windows and their surroundings can be helpful, especially for complex window configurations.

How to Measure the Width of Your Window for Storm Windows?

Measuring the width is the first crucial step. Follow these instructions carefully:

  1. Choose Your Measurement Point: Measure at the narrowest point of the window frame. This is usually the area where the window sash meets the frame. Avoid any areas with molding or trim that might add extra width.
  2. Level the Tape: Ensure your tape measure is perfectly level across the width of the window opening. A slight angle can drastically alter your measurement.
  3. Multiple Measurements: Take multiple measurements at various points along the width. This will help identify any inconsistencies or irregularities in the window frame. Record the smallest measurement.

How to Measure the Height of Your Window for Storm Windows?

The height measurement is equally critical:

  1. Measure From Top to Bottom: Measure from the topmost point of the window frame to the bottommost point. Again, avoid any extra molding or trim.
  2. Level the Tape: Ensure the tape measure is perfectly level from top to bottom.
  3. Multiple Measurements: Take multiple measurements to account for any variances in the frame. Record the smallest measurement.

How to Measure for Different Window Types?

Different window types require slightly different approaches:

How to Measure for Double-Hung Windows?

Double-hung windows require accurate measurements of both the window sash and the frame. Measure both the width and height of the sash and the frame separately. You may need to purchase storm windows specifically designed for double-hung windows to ensure a proper fit.

How to Measure for Casement Windows?

Casement windows open outwards on hinges. Measure the width and height of the window frame itself, just as with other window types. Remember to check if your windows are inward or outward opening and ensure your storm windows are compatible.

How to Measure for Sliding Windows?

Sliding windows operate similarly to double-hung windows, but the sashes slide horizontally. Take measurements of both the stationary and sliding sashes, as well as the entire frame.

What if I Have an Oddly Shaped Window?

For uniquely shaped or unusually sized windows (e.g., arched, round, or angled windows), it's essential to create a detailed template. This might involve tracing the window's outline onto a large piece of cardboard or paper. Then, carefully measure the template for the most accurate results. Consider contacting a professional for assistance with complex window shapes.

What are the Common Mistakes to Avoid When Measuring for Storm Windows?

  • Inaccurate Measuring: Careless or rushed measurements are the biggest culprit. Take your time and double-check each measurement.
  • Ignoring Irregularities: Don't ignore slight inconsistencies in the window frame. The smallest difference can lead to a poor fit.
  • Not Considering Trim: Ensure you’re measuring the frame itself, not including any added molding or trim.
  • Forgetting to Account for the Frame: Make sure your measurements account for the frame and not just the glass itself.

Should I Measure Myself, or Should I Hire a Professional?

While measuring your own windows is feasible for standard shapes and sizes, hiring a professional installer is advisable for complex configurations or if you're unsure about your measuring abilities. Professionals possess the expertise and tools to ensure accurate measurements and a perfect fit.

By following these detailed steps and avoiding common mistakes, you can confidently measure your windows for storm windows and ensure a successful installation that maximizes energy efficiency and comfort. Remember, accuracy is key!
