We offer two different sill sizes for our sash windows, 150mm or 210mm. Both options come with an internal up-stand. The 150mm should be used if a none-projecting sill is required, for example if your window will sit on top of an existing stone sill. If your window requires a projecting sill you will need the 210mm option.
