Takeaways
Reynaers Aluminium is a good fit if you want sleek, modern systems with strong technical backing. Their sliding and facade systems are especially suited for high-end villas and hotels. But if you prefer simpler systems without digital tools, Reynaers might feel like more than you need.
3. DAKO
DAKO was founded in 1994 in Nowy Sącz, Poland. In just a few decades, it has grown into one of Europe’s larger producers of windows, doors, roller shutters, and garage doors. The company employs over 1,200 people and exports to more than 50 countries.
I found DAKO interesting because of how many material choices they provide. While some suppliers limit themselves to aluminum or PVC, DAKO gives you PVC, aluminum, wood, and wood-aluminum combinations. That flexibility makes it easier to match project needs, whether it is a small villa, a hotel, or a larger commercial building. For engineering teams, it reduces the need to split sourcing across multiple suppliers.

4. Groupe LIEBOT
Groupe LIEBOT was officially formed in the 1980s in France, though some of its brands such as K-Line have roots that go back further. Today, the group brings together multiple well-known window and door brands, each aimed at a specific market segment. With more than 3,000 employees across France, Germany, Poland, and Spain, they are one of the largest privately owned window groups in Europe.
Their multi-brand model gives them an edge. Instead of one-size-fits-all, each brand has its specialty, from affordable residential solutions to advanced facade systems for larger projects. I’ve seen how this approach helps engineering teams that want flexibility. It means you can work with one supplier for very different kinds of projects without constantly switching partners.
Products

- Email: contact@groupe-liebot.fr
Takeaways
Groupe LIEBOT is best for businesses that need a supplier able to cover both small residential projects and complex commercial builds under one umbrella. But if you are looking for a highly specialized manufacturer with a narrow product focus, their multi-brand setup may feel too broad.
5. Alumil S.A.
Alumil S.A. was founded in 1988 in Kilkis, Greece, and has since grown into one of the largest aluminum extrusion companies in Europe. With more than 30 subsidiaries and 12 factories worldwide, they serve customers in over 60 countries. Their reach is global, but their expertise remains rooted in advanced aluminum systems for modern architecture.
One thing I find interesting is how Alumil’s projects often combine technical precision with design aesthetics. Aluminum extrusion, which is the process of shaping aluminum by forcing it through a die, gives them the ability to produce complex, durable profiles for windows, doors, and facades. For engineering teams, this means reliable systems that can also be adapted to creative architectural visions.
Products
- Thermal Break Windows: Aluminum windows built with insulation layers that improve energy efficiency in both hot and cold climates.

Takeaways
Alumil S.A. is best for businesses that value strong aluminum systems supported by global logistics. But if your project needs a mix of materials like wood or PVC, Alumil may not be the right partner. Their strength is aluminum, and they stay focused on it.
6. Gealan
Gealan was founded in 1921 in Oberkotzau, Germany, and has specialized in PVC profile systems since the late 1960s. Today, they are part of the VEKA Group, one of the largest PVC profile producers in Europe, with more than 1,300 employees across several countries.
I first came across Gealan through a fabricator I worked with on a residential project. They kept mentioning how easy it was to work with Gealan’s profiles because of their consistency and range of finishes. That stuck with me because in construction, smooth cooperation between supplier and installer can save weeks of frustration. Add to that Gealan’s closed-loop recycling system for PVC, and it’s clear they focus on both performance and sustainability.
Products

Takeaways
Gealan is best for businesses that value sustainable PVC solutions with strong insulation features. But if your project requires premium aluminum or wood systems for high-end hotels or landmark facades, Gealan may not be the right fit.
7. Aluprof S.A.
Aluprof S.A. was established in 1993 and is headquartered in Bielsko-Biała, Poland. It is part of the Grupa Kęty capital group, one of the most important players in the European aluminum market. With more than 2,300 employees and a network of authorized fabricators, Aluprof exports its systems to over 40 countries.
What I like about Aluprof is the way they balance advanced engineering with a very broad product portfolio. Instead of focusing on a single category, they cover windows, doors, facades, roller shutters, and even garage doors. That makes them a useful partner for engineering teams managing mixed-use projects, where sourcing from one supplier can save both time and logistics headaches.
