Stop condensation between windows in a cold garage?

[Farmarskruv38234]

Hello! I have an old cold garage with old window sashes (inner window sashes and outer window sashes, not linked sashes). There is a lot of condensation on the inside of the glass on the outer window sash. How can I stop this?
Grateful for any answers!

The inner frame is not tight enough, and the glass also lets out a bit of heat. The glass of the outer frame is too cold, causing condensation. The outer frame is probably too tight, so there is no circulation between the panes, leading to condensation. Less sealing strip in the outer frame and more in the inner frame should likely solve the problem.
