Weld types in PVC windows

The appearance of a window is very important today. We care more and more about modern interior design. We are also more often giving up curtains and drapes, so that the window remains a very visible design element. Do you know how much the window's appearance is influenced by the sealing technology? Find out what types of seams are used in PVC windows.

If you are choosing windows for your home, the primary parameter you look at is their airtightness and energy efficiency. And rightly so, as they determine the maintenance costs of the house and its functionality. However, the appearance of the windows also matters and whether they fit in with the chosen design style.

In the case of the most popular PVC products, it is primarily the colouring that influences how a window looks. Also of great importance is the way in which the structural elements, i.e. the PVC window profiles, are joined. Welds are precisely the places where profiles connect with each other. They are located in the corner parts of the window and have undergone a decisive metamorphosis in recent years. The direction? Minimalism and modern, streamlined design.

The traditional wide weld is becoming less and less in vogue

The window industry is changing very dynamically. This is due to new consumer and design trends, but above all to the technological progress that is constantly being made in the field of machinery for processing PVC profiles.

Reputable manufacturers who invest in the development of their technology are aware that what was standard until recently is gradually becoming less so, particularly in the premium segment.

This is the case, for example, with the standard wide window weld. In traditional window production, the profiles are joined with so-called flashing, i.e. excess melted material which accumulates at the jointing points. When the flashing is removed, a flat and wide gap (a type of groove) is formed. Nowadays, modern technologies in window production allow other methods of joining profiles. Windows take on a minimalist appearance, typical of aluminium construction, or conversely, the natural character of wooden windows. This is all thanks to modern profile welding technologies, such as thread welding, V-Perfect welding or Holz Fenster Look (HFL) technology.

What is a thin weld?

A thin contour weld allows window profiles to be joined almost invisibly. It is commonly referred to as a thread weld.

In premium products, aesthetically pleasing thin seals are already standard. They are also expected by customers who pay special attention to the appearance of the product. They are most interested in modern and minimalist solutions, especially as fashionable interior designs usually include large glazing and windows are a visible element of the décor and the chosen style.

Thin V-Perfect seal - almost invisible to the eye

Another technological innovation in the production of PVC windows is the V-Perfect weld. This is a seamless connection of profiles at an angle of 45 degrees. As a result, the joining area is thin, flat and almost invisible. The frame and sash are smoothly finished, aesthetically pleasing and minimalist.

With this technology, the welding resembles the way modern profiles are joined together in aluminium windows.

What is HFL technology all about?

With Holz Fenster Look (HFL) technology, the window profiles are joined together at an angle of 90 degrees rather than 45 degrees. This method of joining makes PVC windows look very similar to wooden windows.

PVC window production technology came to us from Western Europe, where it is very popular. It requires a good knowledge of technology and the use of appropriate machines and tools, which makes it more demanding than the traditional method of joining window profiles. However, the end result is worth it, as HFL windows are characterised by an identical appearance to premium products made of wood.

The fashion for wood is definitely back. Not only for interiors, but also for architectural projects. Wooden facades, houses and other structures (even large ones such as offices or hotels) are no longer the future, but the present and a trend that is of growing interest to architects and investors.

Wooden window constructions is part of the same trend. However, wood has many disadvantages and limitations. The most serious is the need for regular maintenance. HFL windows, which look like wood but do not require any treatment, are definitely conquering the European and Polish market today.
