PLEASE NOTE: Above drawings are just examples, actual sill details will be dependant upon door/profile type and jamb size. Flat or No Sill options are only suitable for doors with sufficient overhead protection (minimum 1–1.5m roof cover) and no exposure to rain or water
ingress. For doors exposed to direct weather, a Sloping Sill is strongly recommended to reduce the risk of water intrusion.

Regardless of sill type, we also recommend Rubber seals on all external doors for optimal weatherproofing.
