THE ORIGINAL ROLLER DOOR Measuring Guide
PLEASE ENSURE YOU FULLY READ THIS 'MEASURING GUIDE' BEFORE PLACING AN ORDER! This is a made-to-measure door, once manufactured, cancellations or returns are not accepted.
This single skin roller door can only be fitted BEHIND the structural opening. It can’t be fitted in-between the framework/brickwork. It requires additional space either side of the guides for the steel fixing lugs and protruding barrel.
These steel single skin roller doors are ordered by the actual overall guide width (excluding fixing lugs). The ordering height is the guide height, ideally the height from the floor to the underside of the RSJ/lintel (the curtain roll sits above the guides). Ensure there is sufficient side and headroom for the chosen model and size.
By virtue of their construction roller doors require space above the lintel to conceal the rolled up section of the door. If recommended headroom is not available the door may still be installed, however some loss of opening height will occur and the roll of the door will be visible (this could be disguised with a fascia).
The headroom clearance required (i.e. from the lowest point of the ceiling to the top of the opening) is as follows:
OPENING HEIGHT up to 2135mm HEADROOM REQUIRED 420mm
OPENING HEIGHT up to 2440mm HEADROOM REQUIRED 450mm
OPENING HEIGHT up to 2740mm HEADROOM REQUIRED 480mm
OPENING HEIGHT up to 3055mm HEADROOM REQUIRED 520mm
If the headroom is minimal then a MINI ROLL would be a better option.
Side room clearance required is 75mm each side for single size domestic doors, 150mm each side for double size doors, with an extra 25mm required on the motor side if automation was selected.
Measuring the Height for ordering:
- The Ordering Height refers to the height of the steel side guides NOT including the curtain roll above this height.
Measuring the Width for ordering:
- The Ordering Width for a single skin door refers to the full width of the curtain required plus the width of the guides. 50mm (2x 25mm guides) for doors up to 3450mm and 100mm (2x 50mm guides) for doors over 3450mm.
E.g. If the structural opening is 2200mm wide and 2150mm high, the Ordering Size should be at least 2250mm width (50mm extra for the guides) and 2150mm height. If you have more space available behind the side of the door it is always best to order a door up to 100mm wider than required. It will mean the guides will be totally hidden when viewing from the outside looking in. Having a wider door set behind the reveal can increase the weather protection, security and overall aesthetics of the door.
Every roller door will have a small section of the curtain hanging down slightly when fully open, usually about 50mm, so if you do require the full drive through height when the door is open and you have sufficient headroom, then add on another 50mm or more to the ordering height to take the door curtain higher internally.
Fitting BEHIND the reveal brickwork:
Measure the structural opening of the garage door, take the width measurement in 3 places, across the top, middle and bottom, take the widest dimension. Then add the width of the guides (50mm for doors up to 3450mm wide and 100mm for doors over 3450mm wide). This should be your ordering width.
Then measure the height from the floor to the underside of the lintel. If you have enough headroom above the lintel (between the lintel and the ceiling 420-520mm depending on height), this would be classed as the ‘guide height’ (ordering height).
If you don’t have the required headroom between the lintel and ceiling, you can still order the door but the drive through height would be reduced. In this instance measure the height from the floor to the ceiling in a few places taking the shortest measurement. Then minus 420-520mm depending on the height. This would be your guide height (ordering height).
