Bifold Doors & Windows
Bi-folds are made up of folding door panels referred to as a leaf. They are generally made of multiple configurations or leaves either folding in one direction or both directions like a concertina.
NOTE: You can get one leaf as an active door so that it can be used to go in and out without having to open the entire door system.
Features and benefits of BI-FOLDS (BF)
- You can use the active door to go in and out without opening the entire door,
- You can open the entire space (generally opening outwards for correct sealing),
- You can create large open spaces; generally opening up the room by 90%,
- You can create the illusion of a larger home,
- You can rebate the sill track or use a U-channel guide track to minimize the chance of tripping (water issues need to be considered with this type of installation).
- A sashless double hung window can be placed inside the door sash to allow breeze in without opening the door

- The vast majority of bi-folds windows and doors are top-hung meaning all of the weight is hung from the top. This needs to be considered when contemplating a bifold as structural supports will be required in the head to withstand the weight,
- You will need horizontal structural steel overhead (in the head) to bear the weight of the bifold. Therefore, this is generally not a cost effective option for the home renovator,
- In order to open and close the bi-fold, you need to unlock each section before being able to open the next section and vice versa. This can often be a problem because if you do not lock or unlock the mechanism in its correct position; you will be applying pressure to the lock and run the risk of not getting perfect alignment of the locking pin, and therefore snap the handle,
- Aluminium Bi-folds by their very nature of design have more gaps than sliding doors or stacking doors. These gaps are required for the hinges to work correctly, the doors to hang from the track, et cetera,
- If you opt for a guide track or rebated still, then water penetration can become an issue.

Care of Your Bifolding Products
To help ensure a trouble free life for your new Bi-fold doors, please follow these simple steps:
- Keep fingers clear of all hinging areas while operating your Multi folding doors.
- Ensure any attached active door (if applicable), is folded 180o back against the next door panel before performing the folding operation of your Bi-fold door.
Open Out Bi-fold Doors
- When opening your folding doors, as you operate the Twin-bolt lever, ensure one hand is used to firmly pull the doors inward with the Stainless Steel “D” Hinge handle. This will ensure the top & bottom bolts are able to disengage from the head & sill correctly.
- When closing your folding doors, as you operate the locking Twin-bolt lever, ensure that one hand is used to firmly pull the doors inward with the Stainless Steel “D” Hinge handle. This will ensure that the top & bottom bolts correctly locate into the frame at the head and sill.
Open In Bi-fold Doors
- When opening your folding doors, as you operate the Twin-bolt lever, ensure one hand is used to firmly push the doors outward. This will ensure the top & bottom bolts are able to disengage from the head & sill correctly.
- When closing your folding doors, as you operate the Twin-bolt lever, ensure that one hand is used to firmly push the doors outward. This will ensure that the top & bottom bolts correctly locate into the frame at the head and sill.
- When closing your Bi-fold doors check to ensure the Twin-bolts are retracted – this can be easily identified as when the Twin-bolt levers are in the horizontal position.
Use caution when laying timber decks or internal floor boards adjacent to the Bifold sill. Always provide adequate expansion gaps beside the Bi-fold Sill to allow for the natural expansion of the timber floors. Pressure on the Bi-fold sill can restrict door travel and possibly result in damage to the framing.
Do not obstruct the exterior sill drainage holes with tiles, concrete or other floor finishing’s.
Regular vacuuming of the Bifold Sill track is highly recommended – especially in sandy areas. Build-up of debris in the sill track can restrict door operation and will cause undue wear to the bottom rollers.
