DIY Installation Guide
How to measure, specify, order and decide on the best installation position for your new insulated aluminium roller garage door.
When ordering any of our insulated roller garage doors for a DIY installation it is vital to accurately order your door based on where you are going to install it. Since these doors are all made to order, you can ensure your door is ordered exactly to fit your dimensions.
One benefit of this type of door is that they can be installed in between, behind and in front of the structural garage opening, unlike most other types of garage door.
This page has been devised to help you understand the dimensions you will require when ordering, depending on which installation position you intend to use.
The diagram below shows the important dimensions to verify, as well as some of the terminology regarding these insulated roller doors. This applies to all the SeceuroGlide, GDO ROLL 55 and 77, Samson and Gliderol roller doors.
For the Hormann Rollmatic 2 and T and Garador insulated roller doors the measuring is by their opening sizes, please refer to those doors individually.

Width Dimensions Explained
The Ordering Width when purchasing a double skinned, aluminium, insulated Roller Door is the Overall Guide Width measurement. This is the drive-through width measurement PLUS the width of the aluminium guides on each side - the guide widths vary depending on brand and size of the door being ordered.
For example: a 2500mm Drive-Through Width requires a further 150mm for two standard 75mm width guides, giving an Ordering Width size of 2650mm. If you were to order the door with the 90mm guides, then the ordering size would become 2680mm instead (2500 + 90mm x 2). Please check carefully the guide sizes when ordering and check any order confirmations.

Height Dimensions Explained
When placing an order, the ordering height taken is the Guide Height. This is the total height, minus the dimensions for the endplates which hold the roller curtain and the optional cover hood is fitted to.
The endplate size will vary from one manufacturer to another and also depends on the height of the door, getting larger as the height increases and the roll size increases..
The maximum guide height generally for a domestic insulated roller door is 3500mm, creating a maximum total height of 3850mm with a 350mm endplate.(remove the click here for table link)
This diagram shows the 3 different endplate sizes for the Seceuroglide roller door range with the Compact 55mm roller door having the smallest dimensions.
Three different endplate sizes including the Compact roller door (sold seperately in our online shop).
NOTE: It is important to note with Roller Garage Doors the presence of the Bottom Slat Hangdown, where a portion of the bottom slat hangs down into the opening. With most doors this hangdown is only 55mm, therefore creating a Drive-Through Height of the Guide Height minus 55mm. Please take this into consideration if you have a tall vehicle or high clearance requirements.
Installation Position Options
Face Fitting Internally (Recommended)
Internal face installation is the most common location for roller garage doors to be fitted, and is the most effective way to maximise your drive-through height and width. It is also the most concealed installation, although this factor does depend on personal taste and internal faces being available to fit to
The guide rails and supporting end plates are fitted directly to the internal brickwork face.
If there is only one internal face, with the opening flush to the wall on one side, this is not an issue as the endplates are flush to the guide rails and curtain roll, all contained within the overall dimensions.
Inbetween Fitting
Installing any insulated roller door in between the opening requires more accuracy when ordering your door. Alternatively, you can use packers around the guides and endplates to reach the size requirements or take up and unlevel brickwork deviations In this case, it is vital to use the narrowest dimension. Also, check that the opening is square enough. In some cases, it is required to install the door in between the opening, but behind the lintel, particularly in cases where the lintel is not level with the back of the reveals.
Please note that the guides will be seen from the outside when installing in this manner, so be aware of the colour finish options and whether you want to match or contrast the door colour.
Face Fitting Externally*
When installed a roller door externally it is essential to install a full hood cover . This is to protect the curtain, guides and endplates from weathering. Please note that control box receivers are not waterproof, therefore must be installed internally or in a waterproof casing.
An emergency manual override facility is required with a lockable steel plate fitted to the hood externally for security. However, an optional low level override is available, which is drilled through the brickwork to be operated from the inside. However, this is only possible when separate access to the garage is available.
Also, please note that when fitted externally, it is the internal side of the curtain that is facing outwards. As a result we do not recommend any woodgrain laminate options, as the slats are only finished on the outside, with the inside face painted. Many newer woodgrain painted finishes are finished the same both side, so please check when ordering.
