Before making your final selection make sure you check whether the glass will provide the same level of privacy in daytime and night time when internal lights are on.
Reflective glass is a processed glass which reflects more amount of light and provides mirror-like finish. Reflective glass also blocks solar heat coming from outside and thus helps in reducing the cost of air-conditioning.
Tinted glass is made by adding metal oxides during manufacturing, reducing glare from outside and decreasing the amount of solar heat that reaches through the glass. Tinted glass will provide more privacy than clear glass, as its harder to see in.
The options of patterned and obscure glass are varied, with varying levels of opaqueness and therefore privacy available.
