VLT explains the brightness tradeoff
Visible light transmission, or VLT, tells you how much visible light passes through. Higher VLT keeps a room brighter; lower VLT creates a darker view and may reduce disturbing brightness more strongly.
Glare can affect screens, dining areas and bright rooms. Choose film by the amount of visible light you want after installation, then check its solar-control specifications and appearance.

Balance daylight, comfort and appearance.

Bright living rooms can start with Royal Green 60 or Premium Aquamarine 75. Bedrooms wanting less morning brightness can compare Black Diamond 25 and Premium Black Sapphire 5. Office screens require attention to window orientation and desk positions. Overhead glazing may warrant a separate look at Charcoal Grey 10.
A film that suits one pane may be too dark on another. We discuss room use, existing light and glazing before the final scope is measured and quoted.
