Stable Doors: Cill
A door cill sits at the bottom of the exterior door frame to aid the drainage of water away from the door and house. The depth of cill needed will depend on how far back your door is set into the wall.
| A stub cill sits within the door cavity and is typically used when a cill is required to breach a gap between the new door and an existing structural cill. The stub cill can be placed to allow water to flow down on to the other surface that will drain the water away from the building. |
| The 150mm cill is the most popular option for doors set approx 25 mm back from the brick face. |
| A 180mm cill is typically used for doors that are set further back from the brick face, approx 50mm. |
If the door has a cill as part of the structure of the house, eg. a stone or brick cill, you may not require a cill as there may already be sufficient means of drainage in place.
If a low threshold is required on the door - no cill can be supplied. Please select no cill option.
