Bizarrely I didn’t really think about it at the time and just assumed emergency exits might not be as well insulated as the rest of the fuselage. I was just pleased with the leg-room (6’4” on a Monarch charter…ughhh). I didn’t think it was necessary to inform the crew at the time.
If there was a fault in a seal, wouldn’t that lead to loss of (warm) cabin air around the seal to the outside, warming up the area local to the leak?
Thanks,
Tom.
