ULTRASHIELD's home state. Oregon runs 35% on every window with a strict 13% reflectivity cap — so mirrored films are out. Portland's gray winters hide it, but Oregon UV still fades interiors; ceramic film handles both problems quietly.

VLT — Visible Light Transmission — is the percentage of outside light that makes it through your glass. The number printed in the law is a floor: film may be that bright or brighter. Because factory glass already blocks a little light, an officer's meter reads the combined darkness of glass plus film. A film sold as "35%" on top of factory glass can meter a few points darker — which is why professional installers measure the final result, not the box label.
Quality matters as much as darkness. Dyed films fade purple and bubble; ceramic films like ULTRASHIELD SHADOW reject heat and up to 99% of UV at any legal darkness, with no signal interference — so you get the comfort without gambling on the number.
