Bifold Door Measuring Guide
The width and height of your the bifold door you need to order, is the structural opening size minus a fitting tolerances.
We recommend you allow a 10 - 15mm fitting tolerance between manufacturing sizes and the smallest width and height dimension (please see images).
Use a large spirit level and measure the cross corners of the aperture to ensure the opening is square and true.
Take three width and three height measurements and minus 10 - 15mm from the smallest measurement measured on each dimension to determine the actual required manufacturing size of your door.
E.g, Strutural opening 3015 x 2115mm, recommended size to order 3000 x 2100mm.
Please note that when ordering your bifold doors the overall dimensions includes all components e.g. cills and add ons.
Safe & Secure
