At Jansen Cleanrooms & Labs, we’ve spent more than 30 years designing and building controlled environments for pharma, biotech, microelectronics, and healthcare. Here’s what we’ve learned about the challenges that define each, and how to design for success from the start.

The Einstein Telescope is next-generation underground gravitational-wave observatory that will allow scientists to look deeper into the universe than ever before. And Jansen Cleanrooms & Labs is already playing an active role.

In cleanroom environments, HVAC is both the workhorse and the energy burden. To balance compliance, performance, and cost, a smart HVAC design, combined with modern control systems, is essential. Here’s how to do it well, and how Group Jansen applies these principles.

Cleanroom construction projects face a familiar challenge: complex systems, tight tolerances, and zero room for error. When HVAC ducts clash with structural elements or electrical systems interfere with cleanroom panels, the results are expensive delays and compliance headaches.

When evaluating cleanroom investments, most organizations focus heavily on upfront capital costs. However, this approach overlooks a critical reality: operational expenses can far exceed initial investment over a facility’s lifecycle. Understanding Total Cost of Ownership (TCO) has become essential for making informed decisions that balance performance, compliance, and long-term financial sustainability.

In Leiden, the heart of biotech in the Netherlands, Batavia Biosciences’ brand-new complex now shines brightly. Jansen Cleanrooms & Labs handled the realization of the cleanrooms and laboratories. An impressive project where expertise and teamwork took center stage.

Jansen Cleanrooms & Labs has just announced its first international partnership, joining forces with Turkey-based Altınbölme to bring advanced cleanroom solutions to the Middle East. This milestone collaboration marks a significant step in Jansen’s global expansion, combining Belgian engineering excellence with Turkish market expertise and ambition.

Cleanroom construction is no ordinary building task. In today’s landscape of evolving GMP regulations, stricter ISO 14644 standards, and growing demand for high-performance facilities, success depends on far more than traditional methods.

Whether you are designing a cleanroom for pharmaceutical production, semiconductor manufacturing or biotechnology – ISO 14644-1 provides the foundation. This international standard defines the classification of air cleanliness based on the number of particles in the air. But how do you translate this standard into a workable and compliant practice? At Jansen Cleanrooms & Labs, we help clients not only comply with the standard, but also implement it smartly.

Belgian television broadcaster TV Limburg is launching a series to put the importance of defense for the local economy in the spotlight. We are featured!

Sustainability has become a major priority in cleanroom design. The challenge lies in creating high-performance controlled environments that comply with strict standards such as ISO 14644 and GMP, while aligning with clients’ sustainability goals. At Jansen Cleanrooms & Labs, we place sustainability at the heart of every project, without ever compromising on safety, quality, or regulatory compliance.

1 January 2026. That’s the deadline for your cleanroom to comply with the new PIC/S guidelines, at least if you are involved in pharmaceutical production.
The objective? Harmonising and improving regulatory frameworks and inspection procedures across the pharmaceutical sector.

The primary goal of a cleanroom is clear: ensuring contamination control. But if you need a cleanroom, why not design it to boost productivity too? A smart layout not only improves workflow but also enhances ergonomics and contamination control. Here’s how we make that happen.

Sharp is a global leader in packaging solutions. Originally focused on food, small technical components, and pharmaceutical packaging, the company has since evolved into a specialist in pharmaceutical packaging. Today, Sharp’s engineering team is dedicated to packaging complex and innovative medicines, requiring continuous investment in infrastructure and state-of-the-art production equipment.

From now on, the West Flanders-based firm Sumi will be part of Group Jansen.

In times of crisis when we are overwhelmed by negative news, construction company Group Jansen has a positive announcement to make: they’re acquiring Dutch laboratory furnisher Vinitex. “This marks a new step in our ambitions for international growth,” says CEO Nadia Jansen. “By intensively diversifying, innovating and exploring niches, together we continue to build a sustainable future for our group, our 735 employees and our clients.”

50 years of Group Jansen?
We celebrated until the early hours. This aftermovie is already a fine reminder of this unique party.
