FOR IMMEDIATE RELEASEBrussels, Belgium – June 23, 2025 – The European Window Film Association (EWFA) today issued a statement highlighting window film as a high-impact, low-cost solution to improve energy efficiency across Europe’s aging building stock. With EU countries replacing just 2% of windows annually, millions of outdated single and early double-glazed units remain in service, driving excessive heating and cooling energy use.

High-performance, multi-layered architectural window films can be applied directly to existing glass, delivering measurable benefits:

Atlanta, USA – October 30, 2025 – CoolVu, a leader in architectural solar solutions, today announced its breakthrough Nano-Optic Series window film, engineered to merge nanoscale optical technology with molecular composite coating for unmatched thermal control and clarity.

Designed for both new construction and retrofits, the film addresses strict energy codes (e.g., California Title 24, ASHRAE) by delivering:

Helsinki, Finland – June 1, 2025 – A new study published in Glass Structures & Engineering confirms that advanced photochromic window film can reduce annual building energy consumption by up to 35% compared to standard double glazing. Developed by GPD, the dynamic film adjusts tint with sunlight, optimizing heat and light year-round.
