Roof window

Good visible, the frame of the window is the worst cold bridge. So is at a window the u-value for the glass and the complete window listed.

The roof has a good insulation. Good visible how the temperature increases from the window to the ceiling.

A cold air current makes it in winter uncomfortable to sleep direct below a roof window.
