In your photo, there clearly is condensation on that clear "cover"...that's not something desirable in winter conditions, to the best of my knowledge. Ventilation is very important even in the cold weather.
That's pretty common in Britain too - ventilation via the bottom - but in the US/Canada opinion is divided: northern areas in particular preferring upper ventilation in view of long drawn-out winters with feet of snow which can block ventilation lower down.Almost everyone [in Germany] uses bottoms with screen, only closed while varroa treatment.
Few things:I´m just wondering why is it Germany common to cover the hive with foil and why not in the rest of the world?
New beekeepers start to replace the foil with f.e. beeswrap.
The main argument seems to be, protecting the cover from wax and propolis.
Almost everyone uses bottoms with screen, only closed while varroa treatment.
I started this year without anything cause our Langstroth club is teaching that to beginners.
What do you think about that?

Everyone here has foil on the frames. As I wrote, we have all the screened bottom board and it looks like this:- you do not specify details of your equipment (frame size/under-frame space/bottom type - ventilated mesh vs. closed vs. etc/entrance styles/etc, etc).
Wintering in the Ukraine (UZDA 5) is pretty common under sealed plastic where the bottoms are ventilated mesh OR there is sufficient under frame air space with combination of very well insulated tops.
I say it is rather routine for certain equipment setups.
Sorry, I missed you did state the "Almost everyone uses bottoms with screen............" - which I did not interpret as your case too.Everyone here has foil on the frames. As I wrote, we have all the screened bottom board and it looks like this:
How do you call that?Is this not just a translation difficulty ? The above photo doesn't seem to be a whole lot different to this?
I have not yet seen a YouTube video where somebody outside of Germany used that. .
