Survey Guide and Instructions

As a rule of thumb good surveying practice involves checking your measurements two or three times. Never rely on a single measure. The old adage measure twice make once still applies today.

By checking your measurements two or three times you will help ensure that costly mistakes are not made. The diagrams below are intended to help you in your measuring of your Bi-fold aperture. Remember we view everything from the outside.

Step 1
Measure the diagonals to ensure the opening is square by measuring the diagonals as shown. These should equal to confirm the squareness of the opening.

Step 2
Measure the width in 3 places as shown. (Top, centre and bottom) take the smallest measurement and deduct 10mm to give your manufacturing size.

Step3
Measure the height of the opening in 3 places as shown. (Left, middle and right) Once again deduct 10mm from the smallest measurement to give the manufacturing size. Please see our technical detail of the cill and threshold arrangement, if you need to adjust the height to give a certain threshold floor level. If you are building an extension then the cill and threshold height can be determined to suit.

Step 4
Decide on your design and style and the position of your traffic door if so required. If you have a design that has two traffic doors please indicate which one is to open first.

Step 5
Confirm if your doors requires trickle ventilation for building regulations or general ventilation for the area where the Bi-fold is to be fitted. Please note that trickle vents are only available in White, Brown or Black and KL/RAL colour.
