A window includes a weather seal system that employs two seals. The first seal is located towards an exterior surface of the window and forms an air-permeable water barrier between an active sash and a sill. The second seal is located towards an interior surface of the window and forms a substantially air-impermeable and water-impermeable barrier between the active sash and the sill.
