PRB celebrates its 50th anniversary: ​​half a century of history, know-how and innovation

Half a century of love for a job well done

Founded in 1975 by Jacques Laurent, PRB has become one of France's leading manufacturers of building products over the past 50 years. From a small family business to a national leader, PRB has always cultivated its values: proximity, respect, and friendliness. These pillars have guided its development and commitment to its customers, partners, and employees.

Today, PRB brings together nearly 700 employees, spread between its head office and historic site in Les Achards, as well as its external sites.

A significant historical turning point

In 2022, PRB joined the international Holcim group, a world leader in innovative and sustainable construction solutions. This new step will strengthen its resources, accelerate its ecological transition, and open up new growth prospects.

An anniversary looking to the future

On the occasion of its 50th anniversary, PRB is celebrating both its collective history and its ambition for the future: improving the energy efficiency of buildings, reducing their carbon footprint, and making homes more comfortable. The company celebrated its 50th anniversary alongside its employees and partners on Friday, September 26, 2025, at its Les Achards site, during a friendly and festive evening.

A new chapter in continuity

To mark this symbolic milestone, PRB is evolving its logo. True to its original spirit, this new design affirms the strength of a legacy while ushering in a new era, in line with the challenges and commitments of tomorrow.

At the same time, the website is getting a makeover and PRB is delighted to announce its redesign!
