Sealing the Deal: Addressing Casement Window Gaps at the Top

A casement window can be a beautiful and functional addition to any home. With its classic design and easy operation, it's no wonder that many homeowners opt for this type of window. However, one common issue that can arise with casement windows is a gap at the top, which can lead to drafts, increased energy bills, and even unwanted pests. In this comprehensive guide, we will explore the causes of casement window gaps, discuss various solutions, and provide tips for proper maintenance to ensure your windows stay in top shape.

Identifying the Cause of the Gap

Before diving into the possible solutions, it's essential to determine the cause of the gap at the top of your casement window. Some common reasons include:

1. Window warping: Over time, the wooden frame of a casement window can warp due to moisture or temperature fluctuations. This warping can cause gaps to form at the top of the window.

2. Faulty installation: If the window was not properly installed, it might not sit squarely within the frame, leading to gaps at the top.

3. Worn or damaged hardware: The hardware that enables the casement window to open and close can wear out or become damaged over time. This can cause the window to not close tightly, resulting in gaps.

Solutions for Closing the Gap

Once you've identified the cause of the gap, it's time to explore the various solutions available to address the issue. Here are some options to consider:

1. Weatherstripping: One of the most straightforward and cost-effective solutions for sealing gaps in casement windows is to apply weatherstripping. This can be done using adhesive-backed foam tape or V-strip weatherstripping, which can be easily found at your local hardware store. Simply measure the gap, cut the weatherstripping to the appropriate length, and apply it to the top of the window frame.

2. Adjusting the hardware: If the gap is caused by worn or damaged hardware, you may be able to fix the issue by adjusting or replacing the hardware. This can include tightening screws, replacing worn hinges, or adjusting the window's locking mechanism.

3. Realigning the window: If the window is not sitting squarely within the frame, you may need to realign it. This can involve removing the window from the frame, sanding down any high spots, and re-installing the window to ensure a snug fit.

4. Replacing the window: In some cases, the best solution may be to replace the entire window. This can be an expensive option, but it may be necessary if the window is severely warped or damaged. When choosing a replacement window, opt for one with energy-efficient features such as double-paned glass and a tight seal to help prevent future gaps from forming.

Maintaining Your Casement Windows

Proper maintenance is key to preventing casement window gaps and ensuring the longevity of your windows. Here are some tips for keeping your casement windows in tip-top shape:

1. Regularly clean the window tracks: Dirt and debris can build up in the tracks of your casement window, making it difficult for the window to close tightly. Be sure to clean the tracks regularly to ensure smooth operation.

2. Lubricate the hardware: Over time, the hardware on your casement window can become stiff and difficult to operate. Regularly lubricating the hinges and locking mechanism with a silicone-based lubricant can help keep the window functioning smoothly.

3. Inspect the window for damage: Regularly inspect your casement window for signs of damage or wear, such as cracks in the glass, warping of the frame, or loose hardware. Addressing these issues promptly can help prevent gaps from forming and extend the life of your window.

4. Seal any gaps promptly: If you do notice a gap forming at the top of your casement window, be sure to address the issue as soon as possible to prevent further damage and increased energy costs.

By following these tips and addressing any gaps promptly, you can enjoy the beauty and functionality of your casement windows for years to come. Don't let a small gap at the top of your window turn into a significant problem – take action today to ensure your windows are in the best possible condition.

INSPIRATION & SOLUTION

This newly built private house is in Sydney, Australia. The area occupied by the fenestration system in our scheduled design drawings was up to more than 110 square meters. A wide range of design details made the perfect mix of modern aesthetics and traditional sophistication, the simulated vertical hung windows with tilt & turn opening systems in this home are absolutely breathtaking. SDLS (Simulated Divided Lites with Spacer Bar) brings some historical vintage feeling to the whole building without losing any energy saving performance. Long narrow fixed windows creating larger-than-life expenses, coupled with German high-end systems made this project stand out from the rest.

Simulated Hung Window with Tilt & Turn Openings

Doorwin’s 61S simulated hung windows with tilt & turn openings is a respectful modernization of a classic architectural masterwork.

Why choose the tilt and turn opening method?

Because it generally has better air seals than sliding, single hung, or double hung window frames. Tilt and turn windows form a complete seal when fully closed, this means they are less prone to water leakage, and cold draughts and you’ll keep more of your heating indoors where it belongs. They can be opened in the upper tilt way to ventilate at a minimum opening status and are easy to clean outside of the glass; when there’s a good day, they can be opened as normal inward casement windows.
