Windows do not open, also called fixed windows or fixed windows, it is, contrary to appearances, a very popular solution, used in modern commercial construction but also in single-family construction. Their minimalism, good insulation characteristics and aesthetics attract investors who value functionality and energy efficiency. In this article we will explain what fix windows are, what advantages and disadvantages they have, and where it is worth applying them. Keep reading!
Window fix, also called unopened window, is a type of glazing that — unlike standard windows — do not have a flip or open function. It is devoid of hinges and fittings mounted on the frame. This is a fixed glass embedded in the frame, the main task of which is to illuminate the interior.
Thanks to the simple design, fix windows are more airtight and effective in terms of heat and sound insulation. They are widely used in modern architectural projects, especially where large glazing, panoramic views or the maximum supply of natural light are key.
There are two main types of non-opening windows on the market, which mainly differ in construction and aesthetics. These are:
It is a solution that with its appearance is deceptively reminiscent of a traditional window. As in the case of opening joinery, the glazing is placed in the sash, however, it is deprived of fittings, hinges and handles. Thanks to this, it is perfect for rooms where there are both opening and fix windows at the same time. In this way, a uniform appearance is maintained, which creates a coherent arrangement.
In the case of windows fix in the frame, the glass is mounted directly in the door frame, without an additional wing. This design allows for even larger glazing while maintaining slimmer profiles and a larger glass area. Frame-mounted fixed-type windows are more popular, they are successfully used as shop windows, as well as large glazing in homes. It is also believed that glass windows in the frame are more airtight than glass ones in the sash. However, it is worth remembering that the level of thermal insulation depends on the profile used, the shaft package, the manufacturing technique and whether the installation was carried out correctly.
When choosing fix windows, it is worth paying attention not only to their aesthetics, but first of all to specific technical parameterswhich determine their functionality and energy efficiency. One of the most important indicators is heat transfer coefficient (Uw), which in the case of unopened windows can reach very low values — even below 0.8 W/m²K — thanks to the tight construction without fittings. It is equally important sound insulation, which, with the use of appropriate glass packages, can be as high as 40-45 dB, effectively protecting the interior from outside noise.
It is also worth knowing maximum window dimensions — modern fix windows make it possible to make glazing up to 3 meters wide without divisions, which gives an impressive visual effect. In addition, the lack of opening mechanisms affects not only the lower purchase price, but also better tightness, which translates into real savings in the operation of the building. It is these characteristics that make fix windows more and more often chosen by investors betting on modern and energy-saving solutions.
Although the fix windows impress with their aesthetics and excellent insulation, their non-opening design puts before the investor one key challenge — room ventilation. Not being able to tilt the sash means having to plan Alternative sources of air already at the project stage. They work perfectly here window diffusers mounted in other glazing, recuperation systems whether intelligent mechanical ventilationwhich provide constant air exchange without energy loss. It is worth remembering that proper circulation affects not only the comfort of use, but also the durability of the building itself - it prevents moisture condensation, mold and deterioration of air quality. If you want a modern interior with large glazing, but do not want to give up everyday comfort — combine windows fix with a well-planned ventilation system.
Windows fix are used in both residential and commercial construction. Most often they are found in:
