ST Black 20% Reflective Architectural Window Film: Enhance Comfort, Efficiency, and Style

Large glass windows bring natural light and modern aesthetics to homes and commercial buildings, but they can also introduce excessive heat, glare, and harmful UV rays. ST Black 20% Reflective Architectural Window Film offers an effective solution by improving indoor comfort, protecting interiors, and enhancing the appearance of your glazing—all without replacing your existing glass.

Reduce Heat, Improve Comfort

Whether it’s a home, office, retail store, or commercial building, solar heat can make indoor spaces uncomfortable and increase reliance on air conditioning. ST Black 20% Reflective Window Film is engineered to reject 52% of total solar energy, helping to maintain a cooler indoor environment while reducing energy consumption.

By limiting heat entering through the glass, occupants can enjoy a more comfortable space throughout the year.

Minimise Glare Without Losing Natural Light

Bright sunlight can make it difficult to work on computer screens, watch television, or simply relax indoors. With a 21% Visible Light Transmission (VLT), ST Black provides an excellent balance between glare reduction and natural daylight, creating brighter, more comfortable living and working environments.

Protect Your Interiors

Sunlight doesn’t just create heat—it also causes furniture, flooring, artwork, curtains, and office furnishings to fade over time. ST Black blocks 99% of harmful UV rays, helping preserve the colour and lifespan of your interior finishes while protecting occupants from prolonged UV exposure.
