Casement windows are an attractive and functional addition to any home, but as they age, their weatherstripping can wear down, leading to drafts, moisture infiltration, and higher energy bills. In this comprehensive guide, we'll explore the process of weatherstripping casement windows to keep your home comfortable and energy-efficient.
Before diving into the weatherstripping process, it's essential to understand what casement windows are and how they function. Casement windows are hinged on one side and open outward, usually with a crank or lever. They provide excellent ventilation and unobstructed views, making them a popular choice for many homeowners.
Weatherstripping is a crucial component of casement windows, as it helps to seal the gaps between the window sash and frame. Properly installed weatherstripping can:
Keep drafts out, maintaining a comfortable indoor temperature
Prevent moisture infiltration, reducing the risk of mold and mildew growth
Lower energy bills by improving the window's insulation properties
Reduce outside noise
There are several types of weatherstripping materials available, each with its own benefits and drawbacks. For casement windows, the most common options include:
V-strip (also known as tension seal): This durable, flexible plastic or metal strip is ideal for sealing gaps along the sides and top of the window sash.
Foam tape: This self-adhesive, compressible tape is easy to install and works well for irregular or uneven surfaces.
Door sweeps: These are typically used for doors, but can also be effective for sealing the bottom edge of casement windows.
When selecting weatherstripping materials, consider factors such as durability, ease of installation, and cost. It's also important to choose a material that can withstand the elements and maintain its effectiveness over time.
Now that you have a better understanding of casement windows and the importance of weatherstripping, let's dive into the step-by-step process.
Before you begin, it's essential to inspect the current weatherstripping on your casement windows. Look for signs of wear, damage, or gaps that may be allowing drafts or moisture to enter your home. If the existing weatherstripping is in good condition, you may only need to make minor adjustments or repairs. However, if it's significantly worn or damaged, it's best to replace it entirely.
Once you've determined that your casement windows require new weatherstripping, gather the necessary materials and tools. You'll need:
Weatherstripping material (V-strip, foam tape, or door sweep)
Measuring tape
Scissors or utility knife
Cleaning supplies (such as a cloth and mild detergent)
(Optional) Caulking gun and caulk, if sealing any gaps or cracks in the window frame
Before installing the new weatherstripping, it's crucial to clean the window frame and sash thoroughly. Dirt, dust, and debris can interfere with the effectiveness of the weatherstripping, so use a cloth and mild detergent to wipe down all surfaces. Allow the area to dry completely before proceeding.
Using your measuring tape, measure the length of the window sash where the weatherstripping will be installed. Be sure to measure each side separately, as they may not be identical in length. Once you have your measurements, use scissors or a utility knife to cut the weatherstripping material to the appropriate length.
The installation process will vary slightly depending on the type of weatherstripping material you've chosen. For V-strip, peel off the backing to reveal the adhesive side and carefully press it into place along the window sash, ensuring that the V-shaped portion is facing outward. For foam tape, simply peel off the backing and press the tape firmly onto the sash, making sure there are no wrinkles or gaps. If using a door sweep, attach it to the bottom edge of the window sash according to the manufacturer's instructions.
Once the weatherstripping is installed, close the casement window and check for any gaps or drafts. You may need to adjust the weatherstripping or add additional material to ensure a proper seal.
If you notice any gaps or cracks in the window frame itself, you may need to apply caulk to seal them. Use a caulking gun to apply a bead of caulk along the gap, smoothing it out with a damp finger or a caulk-smoothing tool. Allow the caulk to dry according to the manufacturer's instructions.
To ensure the ongoing effectiveness of your casement window weatherstripping, it's essential to inspect and maintain it regularly. Check for signs of wear or damage, and replace or repair the weatherstripping as needed. By keeping your casement windows well-sealed, you'll enjoy a more comfortable, energy-efficient home for years to come.
Casement windows are the most common style of window. They feature hinged panels that swing open and closed. Casement windows are available in single panels or multiple panels. The direction a door swings, either to the right or the left, is called the handing. In addition to handing, window are identified as either inswing or outswing depending on whether they open into the house or towards the outside.

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.
The client's idea was to maintain a certain vintage feel, and our aim was to meet the energy efficiency needs and standards of modern houses as much as possible while maintaining a retro design. 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.
Our well-crafted bespoke systems enhance the functionality and panoramic view of this modern house.
Huge, fixed glass walls up to seven meters long and two meters high bring great lighting and open views, making it really refreshing to the mind. Five meters high long narrow windows give the whole building a contemporary aesthetic.
