Who makes Comfortrack, I could not find them. Ive seen some very high R
shades avalaible R 4.5. Call your shade Co and Pella or Anderson. If
your window tint was dark it held in more heat than you realise. I would
think glass if it expands slowly will be ok, that yours expanded to fast
when the sun came up. I dought it is the shades but to hot to touch is
reason for concern.

Comfortex makes comfortrack. I'm not sure the exact R value.

It happened toward the end of the afternoon, likely as it got cooler
outside.
