How can I insulate skylights?
My house has been extended and the extension has double glazed windows for roof, think of it as a very sturdy conservatory. I understand why the previous owners did it - to get more space and light, but in terms of heating they have created a disaster.
I could see the issue immediately, but didn't think it would be that bad as the glazing looked to be very modern.
Reinstating the previous garden door inside would not be ideal, so I am now looking for ways to sacrifice light for better insulation.
There is plenty of headroom, so if it was possible to bond insulation to the inside and box it in, that might be a solution.
Is something like that feasible or are there better methods? Thank you.
EDIT - added picture for clarification:
The problematic part is the window panes above the door and normal windows, they form a kind of elongated pyramid shape with a rectangular base area.
