Have you ever felt a draft sneaking in around your windows during a harsh winter storm, or noticed condensation building up on the inside of your window panes? These are clear signs that your windows aren't doing their job of insulating your home effectively. Storm windows offer an extra layer of protection against the elements, helping to keep your home warmer in the winter and cooler in the summer, while also reducing energy costs and protecting your existing windows from damage. But before you rush out to buy new storm windows, accurate measurements are crucial for a perfect fit and optimal performance.
Improperly sized storm windows can be ineffective, letting in drafts and negating their energy-saving benefits. They may even be impossible to install or could cause damage to your window frames. Taking precise measurements ensures that your storm windows fit snugly, providing a tight seal against the elements and maximizing their energy efficiency. This guide will walk you through the process step-by-step, empowering you to measure your windows like a pro and select the right size storm windows for your home.
What tools do I need, and how do I account for different window types?
How do I measure accurately if my window frames are warped or uneven?
To accurately measure for warp or unevenness in your window frames, use a combination of a level, a straight edge (like a long metal ruler or a known straight piece of lumber), and a measuring tape. The level will identify vertical and horizontal deviations, while the straight edge will highlight any bows or twists across the frame's surface. The measuring tape allows you to quantify the extent of any unevenness you find.
To begin, hold the level against different points along the window frame – the top, bottom, and both sides. Observe the bubble. If it's centered, that section is level. If not, note the direction and degree of the deviation. Next, place the straight edge against the frame in various spots and look for gaps between the straight edge and the frame. Gaps indicate warping. Use a measuring tape to measure the largest gaps you find. Pay close attention to corners, as they are common areas for warping. Repeat these steps on both the interior and exterior of the window frame, as warping may not be uniform on both sides. When ordering storm windows, these measurements are crucial. Communicate the maximum deviations to your storm window supplier. They can often compensate for minor imperfections during manufacturing or advise on installation techniques that can accommodate the warp. In extreme cases, you might need to consider repairing or replacing the window frame before installing storm windows for a proper, weather-tight seal. Consider taking photos and detailed notes of your measurements for reference.What's the best way to account for clearance when measuring for storm windows?
The best way to account for clearance when measuring for storm windows is to subtract a small amount, typically 1/8 to 1/4 inch, from both the width and height of your rough opening measurement. This "wiggle room" ensures the storm window will fit comfortably within the opening without binding or requiring excessive force to install, and it allows for minor imperfections in the window frame or opening.
To elaborate, accurate measurements are critical for a successful storm window installation. Taking precise measurements of the window opening where the storm window will be installed is the first step. This "rough opening" is the interior dimension of the window frame. Measure the width at the top, middle, and bottom of the opening, and the height on the left, right, and in the center. Use the smallest width measurement and smallest height measurement as your starting point. Subtracting the clearance amount (1/8" to 1/4") from these smallest measurements provides the "ordering size" for your storm window. The clearance allows for slight variations in the opening's dimensions and ensures that the storm window can be easily inserted and removed. Too little clearance, and the window will be difficult or impossible to install. Too much clearance, and you'll have excessive gaps around the storm window, compromising its energy efficiency and potentially allowing drafts and water infiltration. Some manufacturers may have specific clearance recommendations, so always check their guidelines before placing your order. Remember to double-check all measurements before ordering to avoid costly mistakes.Should I measure from the inside or outside of the window frame?
Measure from the outside of the window frame when ordering storm windows. This provides the overall dimensions the storm window needs to cover the entire opening and ensure a proper seal against the elements.
Measuring the outside of the frame accounts for the full width and height of the window opening, including any trim or molding that the storm window will overlap. This is crucial for preventing drafts and water infiltration. Inside measurements are useful for other window treatments, but not storm windows.
To be absolutely certain of a good fit, take multiple measurements of both the width and height at different points along the frame's exterior. Use the smallest width measurement and smallest height measurement as your final dimensions. This accounts for any slight imperfections or irregularities in the frame and ensures the storm window won't be too large.
Do I need to deduct anything from my measurements for installation hardware?
Generally, no, you don't need to deduct anything from your window opening measurements specifically for installation hardware like clips or screws. The manufacturer will typically account for the space required for their hardware when they fabricate the storm window to your provided dimensions.
Most storm window manufacturers build in the necessary clearances for installation hardware based on the type of mounting system used (e.g., clips, retainers, or tracks). Providing them with accurate measurements of the window opening allows them to create a storm window that fits snugly but can still be installed properly. Over-deducting can lead to a storm window that's too small and doesn't seal effectively, defeating its purpose. However, it is *crucial* to specify how and where you measured. If you measured from inside the window frame where there are pre-existing tracks, you need to clarify this with the manufacturer. Similarly, if you are replacing an existing storm window, provide the existing storm window's *glass* size to the manufacturer, and *do not* measure the frame size. The manufacturer will likely ask clarifying questions to ensure the final product fits your window opening correctly. Always follow their specific instructions and provide accurate information to avoid any fitting issues.How do I measure for storm windows on casement or awning windows?
Measuring for storm windows on casement or awning windows requires precise measurements of the window opening to ensure a proper fit. You'll need to measure the window's width and height at multiple points, both inside and outside the window frame, to account for any irregularities. Take the smallest width and height measurements to order your storm windows.
To begin, identify the area where the storm window will be installed. This is typically the outer frame of the existing window. Using a measuring tape, measure the width of the window opening at the top, middle, and bottom. Record each measurement. Then, measure the height of the opening on the left, in the center, and on the right side, again recording each measurement. It's crucial to measure from edge to edge of the window frame or the area where the storm window will sit; do not measure the glass itself.
For casement and awning windows, pay close attention to any hardware, such as cranks or hinges, that might protrude and interfere with the storm window installation. Note their location and depth to ensure the storm window will fit without obstruction. If the frame is not perfectly square, which is common, use the smallest width and smallest height measurements you recorded when ordering your storm windows. This ensures the storm window will fit within the opening. Consult with your storm window supplier for specific advice based on the type of storm window and your window frame.
What's the best way to measure windows on an upper story?
The safest and most accurate way to measure windows on an upper story for storm windows is from the inside. If inside measuring isn't possible due to obstructions, or if you require exterior measurements, use a ladder safely positioned on stable ground, or ideally, hire a professional window installer or handyman experienced with working at heights.
Measuring from the inside is generally preferred because it eliminates the risks associated with working at heights. Open the window and measure the visible window opening from the inside edges of the frame. Take multiple measurements for both width and height at different points (top, middle, bottom for width; left, center, right for height). Record the smallest width and smallest height as your final measurements. This accounts for any slight variations in the window opening due to age or settling. If you must measure from the outside, prioritize safety above all else. Ensure the ladder is stable, level, and positioned on solid ground. Use a ladder stabilizer or ask someone to spot you. If you are not comfortable working at heights, it is highly recommended to hire a professional. Professionals have the necessary equipment and experience to safely and accurately measure windows, even on upper stories. They can also advise on the best type of storm window for your specific window and installation requirements, ensuring a proper fit and optimal performance.What if my window opening isn't perfectly square?
Don't panic! It's very common for window openings to be slightly out of square, especially in older homes. The key is to measure accurately at multiple points and use the smallest measurements to ensure your storm window fits without binding or getting stuck.
When measuring an out-of-square opening, take width measurements at the top, middle, and bottom of the window frame's opening. Similarly, measure the height on both the left and right sides. Note all these measurements. Then, use the smallest width measurement and the smallest height measurement when ordering or cutting your storm window. This ensures that the storm window will fit within the tightest points of the opening. Remember, it's always better to have a storm window that's slightly smaller than the opening than one that's too large. A small gap can be sealed with weather stripping or caulk, while an oversized window simply won't fit properly and could damage your window frame or the storm window itself. Consider consulting with a professional installer if the out-of-squareness is significant (more than ½ inch difference in measurements), as they may have specialized techniques to ensure a proper fit and seal.And that's all there is to it!
