Anyone who has ever purchased windows knows that their selection is often a long-term decision. Unlike car tires, windows are not replaced frequently. That is why buying them must be a fully conscious and well-thought-out choice. This was exactly the case for our Project Manager, Sławek, who chose Kombisystem windows for his home. Today, we want to introduce you to this product, as well as share the story behind his decision. Let’s dive in!

The eternal dilemma – choose cheaper or more expensive?

 

Any window industry consultant will quickly point out that good windows are not just about aesthetics and matching the building. Comfort of use, durability, and energy efficiency are equally important factors that determine their long-term functionality.

Nowadays, almost everyone building or renovating a home—or planning to replace windows in an apartment—faces a difficult choice. Should they opt for a cheaper solution and risk potential problems in the future? Or is it worth digging a little deeper into their pockets and investing in a high-quality product? This decision carries significant weight because solid windows can last for many years without issues, ensuring energy savings and enhanced comfort.

Sławomir Lejk is a Project Manager at Bertrand with over twenty years of experience. And knows this dilemma all too well. That’s because he encounters customers facing the same challenge every day. Budgets are rarely unlimited, and investors carefully analyze every expenditure, making lower-priced products quite tempting.

Kombisystem windows perfect for your home?

 

Sławek, emphasizing that this is his personal opinion, suggests that price should not be the only factor in choosing windows. “In this case, it’s essentially a double purchase—because in a few years, you’ll be buying windows again, likely at a higher cost,” he explains.

When he was choosing windows for his home three years ago, the decision was obvious to him—he went with Kombisystem. And not just because he has been working in the industry for years and possesses expert knowledge of available market products. His choice was also influenced by the fact that he sees how these windows are manufactured daily, what materials are used, and what technical parameters they achieve. “I respect and appreciate the competition, but when evaluating their products, I could only see the visual aspect. In the case of BB windows, I know their exact production process. I know how these windows are made, what type of steel we use as standard, what kind of hardware is installed, and how many anti-burglary latches they have. That made my choice obvious,” explains Sławomir Lejk.

Durability and quality are exactly what set Kombisystem apart. By choosing it, you invest in a solution that offers excellent thermal and acoustic insulation while being more resistant to weather conditions than wooden windows.

Kombisystem windows – a conscious choice

 

The windows in our experienced sales consultant’s home belong to an older version of Kombisystem, with a rebate. Despite the years, they continue to perform exceptionally well. “This system is the most optimal solution for me. It offers high thermal insulation, and its acoustic properties are comparable to aluminum systems. An additional advantage is its extreme durability, as Kombisystem is resistant to weather conditions—something that would be a concern with more expensive wooden windows,” he highlights.

The features of this system make it a popular choice for both residential homes and commercial buildings. Its excellent insulation properties help retain warmth in winter and prevent excessive heat buildup in summer. As a result, heating costs can be significantly reduced, which is particularly important given today’s energy prices.

Aesthetic and price – a compromise without sacrifices

 

For many people, price is one of the main factors influencing their window choice. Sławek does not deny that it played a role in his decision as well. However, that wasn’t the only reason: “PVC windows are significantly cheaper than aluminum or wood-aluminum windows. But today’s veneers, like the Realwood finish I chose, look just as good as wooden windows,” he rightly points out.

Indeed, modern veneers not only perfectly mimic natural wood but are also highly resistant to external factors. They do not fade under UV exposure, do not require periodic varnishing, and are easy to maintain—just an occasional wipe with a damp cloth. “If I were to replace my windows again, I would still choose between our systems: Kombisystem or Kontur. They have comparable performance, but Kontur has an additional central rigid gasket, which improves security, acoustics, and thermal insulation. On the other hand, I prefer the shape of Kombisystem because my house is more traditional than modern,” adds Sławomir. “It would be a tough choice, but ultimately, I might go for the same system again—a product I know inside out and that has met my expectations.”

Key features of kombisystem

 

The combination of modern technology and durable materials makes Kombisystem windows an excellent choice.

  • High thermal insulation. Thanks to a six-chamber profile construction and an 83mm installation depth, these windows achieve a heat transfer coefficient of Uw as low as 0.73 W/m²K. This makes them ideal for energy-efficient and passive buildings.
  • Excellent acoustics. Kombisystem’s soundproofing properties are comparable to aluminum systems, significantly reducing external noise.
  • Durability and weather resistance. These windows require no additional maintenance and withstand rain, snow, strong sunlight, and temperature fluctuations.
  • High security. Each window is equipped with at least four anti-burglary latches, with larger models featuring even more.
  • Wide selection of colors and veneers. This includes Realwood veneers that perfectly imitate natural wood and Acrylcolor® technology, which ensures long-lasting color durability.
  • Suitable for patio systems. Kombisystem is an excellent choice for lift-and-slide (HST) doors, which, thanks to wider glass packages, provide maximum interior illumination.

 

If we had to summarize Kombisystem windows in one sentence, we would say they are an investment in comfort, security, and energy efficiency. By choosing this system, you receive a product that meets the highest technical standards while also being aesthetically pleasing and adaptable.

Just like in the case of our colleague this choice isn’t just for a season—it’s for years. It will help you avoid unnecessary double expenses and allow you to enjoy reliable windows without concerns.
