Metalunic® is the external Venetian blind that best combines solar shading, security and attractive design. The slats are adjusted internally in the guide profile, so you have full control over their orientation. Metalunic® advantage: the all-metal external Venetian blind is the best in its class. Its fully hidden mechanism offers unobstructed views of the world outside. With Sinus Slats, let in an additional 50% natural light and reduce glare by 25%, thanks to the shape of these slats which reflect sunrays towards the ceiling. Unique curved slat shape lends the facade an aesthetic design. S-shaped for an even stronger design. No more need to compromise with BiColor by choosing a different colour on the inside and outside!
