The two sill options available on our Legacy uPVC sliding sash windows are 150mm or 210mm. Both options come with internal up-stand. The 150mm should be used if a none-projecting sill is required, which in other words mean if your window will sill on top of an existing stone sill. If your window requires a projecting sill you will need the 210mm option.
