A screen+camera would actually enable insanely good insulation, compared to glass. A 4cm/1.6" PUR sheet weights next to nothing and has a thermal transmittance

A screen+camera would actually enable insanely good insulation, compared to glass. A 4cm/1.6" PUR sheet weights next to nothing and has a thermal transmittance (aka u-value) of 0.4 W/(m²K). That's about twice as good as modern, triple glazed windows.

You could just apply a large poster on the front of the door. No need for a screen that generates heat.

  But how does that sell ad space on my consumer attention spot market? And then they can't see the product they're about to buy! /s
