4 uPVC Window Welds Developers Should Know

4 minutes read

When it comes to uPVC windows, the appearance and quality of the window welds play a crucial role. In this article, we explore four different types of uPVC window welds that developers should be aware of.

What Is a uPVC Window Weld?

Welds are the points where the uPVC window profiles are joined together to form window frames. These welds not only impact the overall aesthetics but also contribute to their strength and durability of the uPVC window.  Each weld has unique characteristics and can enhance the visual appeal of the windows.

Let’s dive in and discover the options available for achieving the desired look and functionality.

1. Wide Weld (Traditional)

The wide weld is the traditional method of joining uPVC window profiles. In this technique, excess melted material, known as flashing, accumulates at the jointing points.

After the flashing is removed, a wide groove is formed, which is characteristic of this type of weld. While wide welds have been widely used in the past, they are gradually becoming less popular, especially in the premium segment of the market. The focus has shifted towards achieving a more minimalist and modern kind of design.

2. HFL uPVC Window Corner Weld

HFL (Holz Fenster Look) corner weld technology revolutionized the uPVC window industry by offering windows that closely resemble wooden frames.

With HFL corner welds, the external edges are joined at a 90-degree angle. This unique method creates a seamless and visually appealing corner joint, mimicking the look of traditional wooden windows. HFL corner welds have gained popularity among customers who appreciate the natural character of wood but desire the low maintenance and energy efficiency of uPVC windows.

3. Thin Weld

Thin welding is a modern technique that allows for almost invisible welds and is also known as a ‘thin contour weld’.

Thin welds offer a sleek and minimalist appearance and are particularly favored by customers who value modern design. With thin welding, the joining area between the profiles is thin and flat, resulting in a visually pleasing finish. This technique is often compared to the way profiles are joined in aluminum windows, further enhancing the contemporary aesthetics of uPVC windows.

4. V-Perfect Weld

The V-Perfect weld is another innovative method for achieving seamless and visually appealing uPVC window welds by joining the profiles at a 45-degree angle, creating a flat and precise weld.

The V-Perfect weld is designed to be almost invisible to the naked eye, providing a clean and sophisticated finish. This type of weld is often compared to the perfect joints found in aluminum profiles. The V-Perfect weld is gaining popularity due to its ability to create a high-quality and modern look, meeting the expectations of discerning customers.
