Here are the images of my window (currently it's 18F/-8C outside, 74F/23C inside):
Now, this condensation / ice forming gets even worse - on some days whole bottom of the window from the first picture is completely covered with ice / condensation.
My assumption is that heat loss happens here because edges of windows are not properly insulated. Is that assumption a sound one? This doesn't happen on any other windows in the room - condensation / ice always forms on these two windows.
If I am correctly identifying the problem, few questions:
- What should I use to improve insulation and prevent heat loss here? Generic caulk?
- If I am to use caulk, should I apply it inside or outside? Both?
