EUREKA formwork, available in one- or two-element versions, is designed for the fully concealed installation of low-voltage and 230V luminaires on plasterboard ceilings. This system stands out for its exceptional flexibility, greatly simplifying the installation process. The most innovative feature of the EUREKA System is the possibility of fixing the formwork in advance, allowing the luminaire to be positioned at a later stage. This approach dissociates the two phases, offering optimal management of timing and site operations. This reduces the risk of errors and optimises logistics, making installation easier and safer. Thanks to this versatility, EUREKA is the ideal solution for environments requiring customised design and lighting. The system ensures perfect integration into the plasterboard, preserving the aesthetics of the space without compromising the overall harmony.
