The Jouy-en-Josas municipal offices contacted Wonderglass, a Solar Gard Premium Partner, to support the Jacques Toutain School in complying with the PPMS (Plan Particulier de Mise en Sûreté).

The school needed to preserve student privacy, particularly in classrooms visible from the street. To address this, Sentinel Plus Silver 20, a one-way mirror window film, was installed on all sensitive façades. This solution reflects light like a mirror, preventing visibility from the outside while maintaining clear visibility from the inside, and providing an additional level of protection in case of danger.

Thanks to this quick renovation, the school will also benefit from rejecting up to 86% of solar energy, helping to keep classrooms cooler and improving comfort for both students and teachers.
