Width (1200mm - 5950mm)
Width

Measuring doors & windows is simple but please follow our easy instructions:

  • For bifold & sliding doors to work as smoothly as designed, it is imperative that the outer frame is fitted level and square. To ensure this, you must measure the brickwork aperture as shown below.

  • Three measurements of width and height should be taken and the squareness of the aperture determined by, for example, taking diagonal measurements (see image below). The smallest measurement of width and of height minus a fitting tolerance (usually 10mm) is used to determine manufacturing sizes.

Please also take into account the height of the door’s threshold, that you step over. This is critical for the following reasons:

  • On open-out folding doors with a standard threshold, it allows the possibility of aligning your internal floor with the top of the threshold, to reduce the step over height.

  • On open-out folding doors with an aluminium low threshold, it ensures a level transition from outside to inside, or between internal rooms.

  • On open-in doors it ensures that the opening door sashes do not foul your internal floor.

The industry standard is 150mm. A stub cill may be required if you have a small reveal or are sitting your door forward in the reveal and want to minimize the projection of the cill. You may choose an 180mm cill if the door is sitting back in the reveal and you need to bridge the brickwork at the base of the door.
