Available sizes: 150mm Standard, 85mm Stub and 180mm Extended.

PRO TIP: The cill is an extrusion of uPVC that forms a base for the frame. The cill adds structural integrity and also drains water away.

*Our frames are 70mm in depth, so our standard 150mm cill will extend beyond the frame by 80mm. If you require a cill, it is included in the height provided. Our 85mm stub cill does not include end caps.
