Glass is tempered one and it has black in colour... so far no much difference found in average with and without AC... in fact car is much fast exoist hot air once we open sunroof after parking car in sunlight...
Till now no product for shad but I use to be cut sunroof cushion for shade in extreme high temperature. Also it's not get affected by removing several times.
@Sahil Awana I am not talking about that safety there have been incidents in many parts of the country of throat getting deep cuts from kite thread also known as manza when kids try to peak out from sunroof. Also, if you need to apply sudden breaks I think that's dangerous too. Only if the sunroof is used for what purpose its made its safe.
