Argentum® OS – High-Performance Exterior Silver Films for Extreme Conditions

Argentum® OS sputtered window films are engineered for demanding exterior applications, delivering powerful solar protection, high durability, and long-lasting performance. Built with a specialized toplayer, these films are designed to withstand extreme UV exposure and harsh weather conditions.

Thanks to their advanced sputtered metal construction, Argentum OS films offer exceptional heat rejection and glare reduction, effectively improving indoor comfort while reducing reliance on air conditioning systems. Their high UV-blocking capabilities help protect interiors, furnishings, and occupants from harmful ultraviolet rays, extending the life of materials and enhancing occupant wellbeing.

Available in two optimized versions—Argentum OS 20 and Argentum OS 40—with Visible Light Transmission (VLT) of 20% and 40%, these films give you the flexibility to choose the level of daylight control that best suits your building's needs. Whether you require strong glare reduction or a more balanced light level, Argentum OS delivers high-performance solar control with a sleek, reflective  appearance.

Combining technical excellence with proven durability, Argentum OS is the ideal choice for commercial and residential projects seeking reliable, exterior-grade window film solutions that perform under pressure—without compromising on aesthetics.
