Fitting Requirements
Headroom requirements
Cordula Roller and Cordula Excel require a minimum of 300mm headroom for doors up to 2500mm in opening height and 350mm headroom for door up to 3500mm opening height.
Cordula Manual requires a minimum headroom of 300mm.
Cordula Compact requires just 205mm headroom for doors with an opening height up to 2150mm.
External doors
In applications where the door is installed externally the remote control system must be installed either inside the garage or in a waterproof box (not included).
Cordula Excel restrictions
Cordula Excel is not available as supply only as it must be installed by a trained installer. Cordula Excel can not be installed externally. The door must be installed so that the entire coil is above the opening.
The low level external override option is not available for Cordula Excel. In cases where the garage door is the only means of entry to the garage a battery backup will be required.
All Cordula Excel doors are supplied with 90mm guide rails as standard.
Extreme weather conditions
High winds and high temperatures can cause increased deflection of the door. It is the installer's responsibility to ensure that the door is packed off the wall sufficiently to allow for door movement during these extreme weather conditions.
INTERNAL Face Fixing:
Cordula Roller Garage Doors are installed INSIDE the opening to the garage where headroom inside the garage isn't seriously restricted. Internal reveal fixing may also be used to great effect in arched openings.
EXTERNAL Face Fixing (NOT Cordula Excel or Cordula Manual):
Cordula Roller Garage Doors are installed IN FRONT of the opening OUTSIDE the garage. This is ideal where internal headroom is particularly restricted. Note, some marking may show over time at the upper corners of the door.
REVEAL Fixing (NOT Cordula Excel* or Cordula Manual):
Here the Cordula Roller is installed in the GARAGE OPENING itself. This option gives maximised internal space in the garage, whilst not obscuring the exterior of the garage. Requires good reveal headroom.
When the reveal fix option is chosen it may also be necessary to strengthen the lower edge of a 90o facia when fitted partially or fully into a garage door opening, in order to prevent it from marking the door's curtain during operation.
