About us

Jozef Mintál joined forces with František Mesík from Selce and started producing in a small workshop. Gradually, the first larger orders emerged, including the complete interior of Slovenská sporiteľňa on the square in Banská Bystrica.

A strong moment of this period was the production and installation of oak stairs in the Leaning Tower in Banská Bystrica. The technically demanding realization, which is still in use today, became proof of craftsmanship, precision, and the courage to take on challenges.

After a failed business partnership in Zvolen, Jozef Mintál decided to practically start from scratch. He was left with a small workshop, basic machinery, and a new team.

It was during this period that he first encountered the production of euro windows more intensely, which later proved to be a key moment for the future direction of the company.

When working on a contract for the District Court in Zvolen, the company's management faced a fundamental decision. External frame milling was so expensive that Jozef Mintál realized that for the same money, he could buy his own machine.

He therefore decided to invest in the first dedicated bottom milling machine for window production, and they completed the contract in-house. This step marked the definitive entry into window production, and the company began to establish itself as a window manufacturer.

It was no longer possible to manage the growth in production under the original conditions. In April 2000, the company moved to larger premises in Sliač, where it had approximately 500 m² divided into two production halls at its disposal.

For the first time, there was a real opportunity to separate individual production phases and elevate the organization of work to a higher level. This was an important step from a small workshop to systematic production and further professional growth of the company.

After years of working in rented premises, a strategic decision was made to build their own production complex. Construction began in April 2005, and by September, the company had moved into its new premises in Sielnica.

Production was designed systematically for the first time, with a separate paint shop, assembly, ventilation, and logistics. 2005 marked the transition to a stable manufacturer with its own facilities and a clear vision for further long-term development.

In 2008, we significantly advanced production by investing in the first five-axis CNC machines from one of Europe's largest machine manufacturers, SCM Group.

Automation brought us higher precision, stable quality, and faster production. This created a technological foundation that put us ahead of most of our competitors.

In 2013, MINTAL launched its timber-aluminium window production program, which gradually became the main pillar of its production. This step significantly strengthened the company's profile as a premium Slovak manufacturer, with an emphasis on quality, technology, and precise workmanship.

The launch of the program was made possible by the financial stability achieved after challenging investment years and the repayment of loans, which opened up space for long-term development and investment in production for the company.

The year 2016 brought another important step in the development of MINTAL. The construction of a new production and assembly hall expanded the production facilities and created conditions for the further growth of the company.

Increased capacity allowed for more efficient production processes, better organization of assembly, and readiness for the growing demand for MINTAL timber-aluminum windows.

Following the expansion of its production facilities, the company once again invested significantly in technological innovations. It introduced a robotic line for window surface treatment, which brought higher precision, efficiency, and repeatability in painting, while also reducing material waste.

Thus, 2022 marked another technological advancement for MINTAL and reaffirmed its emphasis on modern manufacturing technologies.

In 2024, we opened a modern MINTAL showroom in Sielnica, which opened the doors of production to customers. Visitors can not only see but also truly experience wood-aluminum windows. The space combines design, technology, and transparency and showcases current trends, premium materials, and processing details.

The visit also includes the opportunity to walk through the production process and observe it from wood processing to the final product. The idea is simple: trust is built when the customer sees how things are made.

The growing interest in MINTAL wood-aluminum windows from various parts of Slovakia naturally brought about the need to be closer to clients from the western region as well. That is why we opened a consultation center in Berg, near Bratislava.

It is a place where you can view our solutions, compare materials and processing details, and consult with our team when choosing the ideal solution for your project.

At the beginning of 2026, MINTAL introduced the new ZEN, which the team had been intensively working on throughout 2025. The development was preceded by months of design, technical development, and testing, which responded to the need for more light, space, and cleaner architecture.

Inspired by Zen philosophy and Japandi aesthetics, an ultra-slim timber-aluminium window frame was created without compromising on quality and stability. MINTAL ZEN represents a milestone where technical precision meets modern living.

Today, MINTAL is a stable company that has grown from craftsmanship, hard work, and perseverance. What started as a small workshop gradually became a production facility, but one thing has not changed.

An emphasis on quality and an honest approach. In the future, we want to remain steadfast in quality and continue to grow naturally, just as we have done from the beginning.
