Are Commercial Window Films Really Worth the Investment for Businesses?

I’ve recently been exploring the growing trend of commercial window films and how they’re helping businesses improve comfort, privacy, and energy efficiency — all without replacing existing glass.From what I’ve seen, they offer great benefits like UV protection, glare reduction, and lower cooling costs during summer. But opinions differ on whether they’re truly worth the long-term investment, especially for large commercial spaces.So I’m curious —

• Have you (or your company) installed commercial window films?
• Did you actually notice a difference in energy bills or workspace comfort?
• Which brand or type worked best for you?

Would love to hear real experiences and honest feedback from others in this space.
