The best product, Metalunic is the external venetian blinds that best combines solar protection, safety and aesthetics. The slats are adjusted directly in the guides, giving you total control over their orientation. Metalunic has a sleek design, with no visible cords, and an intelligent motor for smooth, silent closing. It also has an automatic stop in the event of an obstacle and an anti-lift device that locks the slats. And it's easy to clean. There's also the Metalunic Sinus version, which lets in 50% more natural light thanks to the sinusoidal shape of the slats, adding an extra touch of aesthetics and design to the façade.
