The Sputter ST40 Safety Film is designed to provide both solar control and added safety for residential and commercial spaces. With a 40% visible light transmission (VLT), it allows comfortable daylight while reducing glare, making it suitable for offices, living rooms, and storefronts.
Engineered with sputtering technology, ST40 offers 76% total solar energy rejection, effectively lowering indoor heat and improving energy efficiency. It blocks 99% of harmful UV rays, protecting interiors and skin from sun exposure. For maximum thermal comfort, the film achieves 96% infrared rejection at 950nm and 99% at 1400nm, minimizing heat penetration.
Built with 6Mil thickness and a 3H scratch-resistant coating, ST40 also functions as a safety film, providing extra reinforcement to windows against accidental impacts or breakage. This makes it a dual-purpose solution for comfort, energy savings, and security.
