The Lamilux MS78 high performance is a modular skylight system that offers exceptional design flexibility. The modules are available in standardized widths and heights and can be fixed or motorized. Install is aided by the precision-built self-aligning structure that receives and connects each module. The elegant and narrow width of the structural components (3'' / 78mm) maximize daylight incidence and ventilation potential. Durable, high quality sealing and its thermal bridge-free design assure that you will have clear views of the sky, daylight in the spaces below, and energy savings with the MS78 for many years.

With USA-based technical sales support, we can integrate the MS78 in your next project. We offer owners, architects, and engineers detailed production drawings and on-site support from our Authorized Installation Representatives to ensure seamless transition into the roof assembly.
