This single casement window combines a top-hung vent with a side-hung opening casement below, making it a flexible option for everyday ventilation and comfort. The window is built as one complete unit and divided by a real horizontal transom, allowing each section to open independently while keeping the overall frame clean and balanced.

The top-hung vent opens outward from the bottom, which is ideal for controlled airflow. It allows fresh air to enter without opening the window fully, helping to reduce draughts and maintain privacy. Below it, the side-hung casement opens outward, giving wider ventilation when needed and making the window easy to use for daily living.

This setup works especially well in kitchens, bedrooms, and living spaces where you want both gentle background ventilation and the option for stronger airflow. It’s also a popular choice in homes that already use uPVC casement windows, as it blends in naturally with other window styles while offering more flexibility.

Because the window is split into two opening sections, airflow can be adjusted depending on the weather or time of day. The real transom adds strength to the structure and keeps both sashes operating smoothly. Despite having two opening parts, the window remains straightforward to maintain and practical to clean from the inside.

As part of a wider range of uPVC windows, this configuration offers a good balance between ventilation, usability, and appearance. It suits both modern and traditional homes and provides a reliable solution for homeowners who want more control over how their windows perform without adding unnecessary complexity.
