IR glass option avail?

[djp714]

In our GL450, we had the option to special order IR Glass which provides Infrared reflecting glass for the front sides and windshield. It's clear, double laminate glass. The glass does an amazing job of keeping the black interior cooler during the summer.

Does anyone know if the new F15s can be ordered with a similar option? I noticed reference to 420 Sun Protection Glazing which I'm assuming is the standard privacy glass for the rear windows and does not have infrared reflecting properties.

Thanks in advance.
