Glass Clarity & Light Transmission
The measure of visible light that passes through glass, expressed as a percentage. Higher light transmission values indicate clearer, more transparent glass.
Technical Details
Standard clear float glass transmits approximately 83-85% of visible light (for 1/4" thickness). Low-iron glass achieves 91%+ transmittance. Light transmission decreases with glass thickness, tinting, and coatings. For architectural glass railings, clarity is a key aesthetic consideration, particularly at panel edges where the green tint of standard glass is most visible.
Frequently Asked Questions
What affects glass transparency in railings?
Glass thickness (thicker = slightly less clear), iron content (standard vs. low-iron), surface coatings, and edge treatment all affect perceived clarity. For maximum transparency, low-iron glass with polished edges is recommended.
