Cill Information
The purpose of the cill, which is located beneath the frame, is to remove rainwater. Unless it’s concrete, a Cill that already exists should typically be replaced. We provide three sizes, and ours are 30 mm high:
85mm: This is utilized when the frame is positioned forward in the reveal and has a 15mm projection.
150mm: This is the most popular size, which has an 80mm projection.
180mm: When the frame is positioned farther back in the reveal, 180mm is utilized with a 110mm projection.
Important: If necessary, enter “overall” sizes that include add-ons and/or cill.
