Sun control/reflective film for glass door!

[Anonymous]

Please help! We havea glass door in front of our black main entrance door. Our house faces the sun, so by mid morning both the black door and the glass door are BURNING HOT to the touch. It's very uncomfortable for me, and I'm starting to get anxious about DD touching it and hurting herself..she touched it once and cried for a few minutes but thankfully didn't actually get burned.

My FIL mentioned we could get something like a reflective film/sun control film to put on the glass door which would prevent it and the black door from getting so hot.

Anyone know where I could find this?
