Measuring
Insulated roller door’s can be fitted within OR behind your brickwork/timber frame. All roller doors are made to measure to suit your exact brick opening. They are ordered by the OGW (Over Guide Width or Curtain Size) by their GH (Guide Height). Therefore, you need to order the door at the correct OGW x GH.
Fitting behind brickwork
OGW This needs to be your brickwork aperture size + 200mm. For example, if your brickwork opening is 2100mm the OGW needs to be 2100mm + 200mm = 2300mm. So 2300mm is your OGW and ordering size.
GH This needs to be your floor to lintel height. You do need to add on + 300mm for this. Please be aware that the roll is additional in height to this as it will sit behind the back of the lintel.
For example, if your floor to lintel height opening is 2200mm the GH needs to be 2200mm + 300mm = 2500mm. So 2500mm is your GH and ordering size.
Fitting between the opening
OGW This needs to be your brickwork aperture size (we will make the door to suit this size with the relevant guide sizes). For example, if your brickwork opening is 2100mm the OGW needs to be 2100mm. Please be aware that the guide sizes above will reduce your opening size so if your opening is 2100mm your drive through width will be -200mm so reduced to 1900mm.
GH This needs to be your floor to lintel height less the roll size stated above as this will all need to all be fitted within the opening. So, for example, if you want a C77 and your height floor to lintel underside is 2100mm then you would order your GH at 2100mm – 300mm The C77 needs 300mm for the roll) = 1800mm.

Please be aware that as roller doors are bespoke, made to measure products they cannot be returned or cancelled once the manufacturing process is underway.
