Retrofitting double glazing both end of our hall in old villa. Low E glass from memory (no argon)

They have replaced 3 of the four glass panes around the front door with double glazing glass while the 4th window is still single as it is inside the door which is being replaced.

Outside its a chilly 0.8C but there is no discernible difference in temperature when I touch the glass of the double glazing units vrs the original 50+ year units.

(frames all wood).

I'm a bit confused about this as I thought the DG glass panes would be less cold to touch ?

Is it just because it so cold outside and glass is such a good conducter that it sucking enough heat that it feels cold either way?


A.

Have one of those IR thermometer guns on back order anyway so might measure the actual temperature of the glass panes to put numbers to the impression...
