Abstract
Abstract An outer window (1) for an inner room contributes to increased heating costs. These costs can be reduced by fitting an extra window (5) on the outside of the outer window (3) against which it is sealed, except for a gap (6) at the bottom for inflow of air between the two windows. The air flows through a passage (4) through the window upper arch part to the inner room (10).
