Avery Dennison®
Clima Sterling DR™
solar window films

A dual-reflective (DR) window film features different reflectivity levels on its interior and exterior surfaces — typically a higher exterior reflectivity to reject solar heat and a lower interior reflectivity to preserve outward views and maintain natural night-time clarity.

This two-sided optical balance means:

• Exterior face: Reflects incident solar radiation, significantly reducing heat gain and HVAC load
• Interior face: Minimises mirror-like appearance from inside, maintaining clear sightlines after dark

The Avery Dennison® Clima series applies this dual-reflective architecture across its commercial and luxury residential range, allowing architects and facility managers to achieve intelligent solar control without compromising the building's aesthetic integrity. The result is consistent indoor thermal comfort, glare reduction, and more than 99% UV blockage — all within a film that integrates seamlessly with modern glazing systems.

Clima Sterling DR™ delivers stable energy savings by continuously rejecting solar heat before it penetrates the glazing — reducing the thermal load on HVAC systems and lowering operational costs year-round.

Its advanced solar control technology:

• Minimises interior heat buildup without compromising natural daylight
• Reduces HVAC strain, resulting in lower and more predictable energy bills
• Performs consistently across varying sun angles and seasonal conditions

Yes, in certain conditions. High-reflective window films can increase the thermal differential across a glass pane, which — on incompatible or already-stressed glazing — may contribute to thermal stress fractures. Prior to installation, a glass compatibility assessment is strongly recommended to evaluate the specific glazing system, frame type, and solar exposure.

No — silver finish films in the Avery Dennison® Clima series are engineered to maintain high night-time clarity and allow natural daylight to illuminate interiors. The reflective exterior appearance does not translate to a dark or oppressive interior environment. Occupants benefit from filtered, comfortable light, with harsh glare and blinding sunlight screened out — not daylight itself.
