For heritage conservation, the Viking Sliding Sash window offers a traditional profile with the option of decorative glazing bars. The window sashes separate when opened, thus avoiding wear on the weather strip. On closing the window, the sashes are pressed against the weather strip, making a tight seal. Sashes slide up and down as well as tilting open.
