I have a questions regarding a 2012 A3 2.0t quattro with the open-sky sunroof.

Is there UV/IR protection? I don't know enough about UV/IR; does it penetrate glass? Does the tint of the roof add protection? If so, how much? Is there a specific rating associated with the O-S roof? Does the sunshade provide additional protection?

This is a really important issue for anyone sitting in direct sunlight that comes through a window. Normal glass blocks all of UVB but allows UVA to come through. Both of these rays are harmful. Remember:

UVB

UVB is considered the main sunburn ray
It causes skin cancer and sun damage
The SPF in a sunscreen tells you how well the product protects you from UVB

UVA

Is the UV ray in tanning beds
It penetrates the skin more deeply than UVB playing a big role in sun damage including wrinkles
It can cause skin cancer
The SPF on sunscreens tells you nothing about whether the product protects you from UVA. Look for sunscreens labeled ‘broad spectrum’, but even then full UVA protection is more complex. Bottom line, I recommend mineral sunscreens for the best, most reliable UVA protection (click here to read more) or Mexoryl SX if you really don’t like mineral sunscreens.
