At least that’s what AvtoVAZ itself says
AvtoVAZ drew attention to one feature of Lada cars, which is not obvious to everyone: it turns out that even the most affordable Lada Granta is equipped with athermal glass.
«Volzhsky Automobile Plant went to meet customers halfway. Now even on the most affordable "Grant" By default, thermal glasses are installed », — Volzhsky Automobile Plant said in its Telegram channel.
When creating athermal glasses (they can be distinguished by their green or blue tint), special impurities are used. Such glasses block infrared radiation, reducing heating of the car interior in summer, and in winter, on the contrary, they release heat from the interior more slowly.
