Generated explanation

The illustration shows a cross section through the bottom portion of an aluminum casement window, with the outside on the left and the inside on the right. A factory-sealed double glazing unit with a spacer is supported within the window sash. Thermal breaks separate exterior and interior portions of the aluminum sash and frame to interrupt conductive heat transfer. Air seals are shown at the sash-to-frame interfaces, while drainage holes and a dashed drainage path direct water toward the exterior above the sill.
