External Cills for VisTA Aluminium Sliding Patio Doors

Our aluminium cills for patio doors are available in four sizes 85mm, 150mm, 190mm and 225mm. The standard size for a normal brickwork aperture is 150mm, which provides a 50mm ( 2" ) overhang, when the back of the door frame is fitted in line with the back edge of the outside brickwork. The 85mm cill, sometimes referred to as a stub cill, is used when the door frame is fitted forward in the brickwork reveal and likewise the 190mm and 225mm cills are used when the door is fitted further back in the reveal. The 190mm and 225mm cills have to be selected on triple track sliding patio door systems, due to the width of the bottom frame. Please go to threshold details for further information.
