insulation
Las ventanas son una barrera contra el aire, agua, polvo y contaminación.
Windows are a barrier against air, water, dust, and pollution. The most vulnerable point in a house is found in the facade openings, which are occupied by the windows.
The type of material used for the facade determines the degree of heat gain from the outside, thus impacting the electricity we use to heat and cool our home. Thanks to their technical design, KÖMMERLING PVC windows significantly reduce heat gain compared to other windows, making your home a comfortable, durable, and economical environment.

Frequently Asked Questions
Why do PVC windows offer better thermal and acoustic insulation?
PVC windows are manufactured with multi-chamber profiles specially designed to reduce the transmission of temperature and sound between the exterior and interior.
This internal structure, combined with proper perimeter sealing and the possibility of incorporating double or triple hermetic glazing, allows:
For these reasons, PVC has become one of the most widely used materials in modern and efficient window systems.
Porque los perfiles para ventanas requieren un PVC formulado con estabilizantes, modificadores de impacto y protectores UV, lo que garantiza rigidez, aislamiento térmico, resistencia al envejecimiento y estabilidad dimensional incluso en condiciones climáticas exigentes.
Finally, it is a long-lasting material whose ingredients – petroleum and rock salt – are preserved as such, allowing them to be recovered and reused to manufacture new PVC products. At Kömmerling, for over 30 years, production offcuts from profiles have been recovered and reintroduced into the production cycle.
Plastic has become the dominant material in older buildings. Isn't that a contradiction?Today, advances in chemical and industrial engineering make it possible to fully recycle dismantled PVC window profiles. The new profiles, produced with a blend of recycled PVC, are indistinguishable from those made without this blend. Their quality, both aesthetically and technically, meets or even exceeds current industry standards.
Plastic has become the dominant material in older buildings. Isn't that a contradiction?
No. Today, thanks to advances in chemical and industrial engineering, it is possible tocomplete recycling of PVC window profilesonce disassembled. The new profiles are manufactured with a mixture of recycled PVC.They show no differences in appearance or technical performance.compared to profiles produced with virgin material. Their aesthetic quality and structural performance meet, and even exceed, current industry standards. Furthermore, the long lifespan of PVC and its high level of thermal insulation contribute to reducing energy consumption in buildings, thus decreasing the environmental impact over time.
A highly variable system technology makes virtually any window shape possible in all its details, maintaining or improving the aesthetics of the house, thanks to the thermoplasticity of the PVC profiles.All types of bows and special designs can be manufactured with great precision.
Furthermore, this level of adaptability is combined with high thermal insulation performance, which contributes toto reduce energy losses and decrease electricity consumption in air conditioninggenerating sustained savings over time for the end user.
No. In fact, using PVC windows in older buildings significantly improves their energy efficiency. By replacing deteriorated frames, heat loss, energy consumption, and emissions associated with heating and cooling are reduced. This makes PVC an environmentally friendly material for renovations.
Furthermore, modern profiles are manufactured with stable, recyclable, and age-resistant formulations, which eliminates the need for frequent maintenance and reduces waste generation. Their long lifespan, recyclability, and energy savings make them a solution that aligns with current sustainability criteria.
PVC windows quickly became popular due to their durability and ease of maintenance. For the first time, there was an ideal material that was completely resistant to corrosion and decay. Since 1967, Kömmerling has been a pioneer in systems technology and currently operates successfully throughout Europe and the world.
There is no doubt that Germany is the world's leading consumer of PVC windows. Progress began there. Soon, windows were tested in extreme climates in other countries, along with special resistance tests. Today, the concept of PVC windows has spread worldwide.
A simple tour of their manufacturing, research, and quality control processes demonstrates this: at Kömmerling, there are more testing procedures than production procedures. Testing is carried out at every stage – from the supply of raw materials to windows installed in extreme climates.
Regular testing by independent testing institutes confirms the high standards of quality for all Kömmerling products.
No. Even windows that look similar on the outside can be completely different on the inside. The quality of the material, strength and durability, construction, and workmanship all differ, as do the profile structure, sealing system, and the variety of systems. Proper installation and correct attachment to the building are also determining factors.
Absolutely. Even decisively. Internally, they essentially determine whether we feel comfortable, whether the house or apartment "works." Externally, windows can structure facades, smooth them, or make them sculptural, defining the character of a house through large windows or partitioned walls. Why has the topic of windows become so important? Aspects such as comfort, cost, and the appearance and prestige of a house are directly related to the windows. With PVC windows, the physical performance of the building takes on significant importance. Outside noise, energy savings, the desire for security, and the wish to increase the property's value are all factors that have made windows a fundamental element of construction.
Absolutely not. With its system technology for entrance doors, Kömmerling offers unique profile technology that provides high stability and burglary protection according to DIN standards. Moreover, these profiles not only meet the rigorous quality and testing requirements for entrance doors, but they also belong to the top group of profiles in terms of thermal insulation.
Both the facade architecture and the layout and use of the spaces are determining factors. Thanks to the diversity of KÖMMERLING profiles, it is possible to achieve virtually any type of partition.
However, it is recommended to avoid excessively wide window sashes, as their inward opening can affect circulation and the use of space, and alsoThey are not advisable from the point of view of safety standards and structural stability.
In windows divided into several sections—for example, with a top sash—or in door-window units, the opening mechanisms can be combined as needed. Kömmerling systems include sliding and folding doors. These elements, typically large in size, bring nature into your home.
Yes; and sliding windows too, with the same, particularly narrow, profiles. Large windows or patio doors, well-oriented and with good views, make these windows very attractive. At the same time, the room looks more spacious. In winter, the sunlight can contribute to lower heating costs.
Yes. KÖMMERLING offers highly regarded complete solutions for both new and existing homes. In renovation projects, this system facilitates the efficient and aesthetically pleasing installation of blinds.
In addition, closed blinds significantly improve thermal insulation, giving the home a more comfortable and welcoming atmosphere.
To achieve maximum performance, it is essential to precisely define the project's needs. In addition to the building's specifications, it is important to detail aspects such as the required level of airtightness, height, and desired thermal and acoustic insulation.
With this information, architects and manufacturers can flawlessly design the right windows, selecting the KÖMMERLING solution that best suits each case.
With these modern windows, equipped with suitable insulating glazing, you can save up to 75% on heating energy compared to older windows with single glazing. Similarly, during hot weather, you'll achieve equivalent energy savings in cooling systems.
The high level of insulation of PVC windows is mainly due to the multi-chamber structure of their profiles, the low thermal conductivity of the material and the quality of the sealing system.
Furthermore, the type of glass installed (double or triple glazing) plays a fundamental role in the final performance of the window, allowing for optimization of both interior comfort and energy efficiency of the home.
Due to the difference between outside noise and the level of silence inside. With special soundproof glass. Kömmerling window systems allow you to achievefrom 32 dB for a window with 4/12/4 glass to 47 dB for 11/16/9 laminated glass with a filled cavity.The factors that fundamentally influence acoustic insulation, in addition to airtightness, are: the construction of the profiles, the thickness of the glass, the distance between panes and the general construction.
Yes; according to tests and analyses, they are usually disproven.Old windows were tested for durability. Seventeen-year-old windows, which had not undergone any restoration work, proved to be in perfect working order and free of any signs of material aging.
Yes. This is one of the advantages of system technology. Depending on the level of outside noise and the use of each room, it's possible to choose different sound insulation configurations while maintaining the same exterior window design.
For example, a bedroom requires a higher level of soundproofing than an office or a social area, allowing each space to be adapted to its specific needs without affecting the overall aesthetics of the project.
According to DIN 7748, PVC cores are classified as having "normal impact resistance" and "high impact resistance." Impact resistance determines the quality of the window and its performance in hot and cold conditions (corner strength, for example, depends directly on it). Kömmerling's proprietary formulation, Kömalit Z, exceeds the requirements for the highest category.
Regarding the strength of the windows, it should be noted that Kömmerling PVC profiles are reinforced with large internal metal profiles.
The permissible static load meets the most stringent requirements for tall buildings. Even in the worst storms, the windows remain airtight and watertight, complying with the strictest German and international building standards.
Another advantage is the extreme strength of the corners. The PVC used in Kömmerling profiles, which is highly impact-resistant, is also heat-welded without glue. The resulting seamless joint appears to be made from a single piece, offering the best solution both mechanically and aesthetically.
Installing windows manufactured with KÖMMERLING systems not only increases the construction quality and value of the home, but also directly improves thequality of life of those who live there. calidad de vida de quienes la habitan.
A well-executed renovation allows for:
Besides, It improves its image and enables practical and substantial modifications in the use of space.
It usually takes only a few hours, or a few days for larger projects. New windows are supplied fully glazed. The old window is removed, the new one is installed and secured, the gaskets are fitted, and the appropriate sealing is applied.
This is where the expression "ease of maintenance" truly comes to life. The flawless, satin-matte surface is less susceptible to dry, wet, or aggressive dirt than a cracked finish. A mild detergent is usually sufficient for regular cleaning. In addition, it is recommended to perform a periodic examinationbasic inspection and lubrication of the hardware, in order to ensure correct, smooth and long-lasting operation of the opening and closing system.
