Insulating hive Sleeves

I could feel the warmth of the freshly exposed glass and also watch the underside steam up after about a minute with the insulation removed.

I've seen that too.

I have a 5 frame nuc with a tiny colony in it (made up from apidea left-overs), it's surrounded by a 2" insulation sleeve and is still going strong. The roof is glued onto the insulation so the whole thing lifts off the nuc.
