WindowMaster International A/S & Fieger Lamellenfenster GmbH achieves new EN 12101-2 system certification supporting safer, healthier buildings
A new system certification in accordance with EN 12101-2 now provides clear answers: WindowMaster and FIEGER have jointly developed a tested and certified louvre window drive system that performs impressively both in the event of a fire and in daily ventilation operations. For architects, specialist planners and operators, system certification means one thing above all else - reliable evidence that simplifies approval processes and minimises compatibility risks.
The tested unit consists of:
- the WML 870 louvre drive from WindowMaster
- the FLW 32 louvre window from FIEGER
Together, both components meet all the requirements of EN 12101-2, providing planners with a quality-assured solution that complies with both safety standards and today's expectations for natural ventilation.
“Fire safety is non-negotiable and should be a top priority for everyone from planners to facility managers – regardless of the building. In FIEGER, we have found a partner who shares our commitment to maximum building safety.
We are therefore delighted about this collaboration and the successful certification.”
Erik Boyter, CEO, WindowMaster
The cooperation between WindowMaster and FIEGER thus supports the development of healthy, energy-efficient and modern buildings that benefit both people and the environment.
