How frameless bifold doors open and close?

Frameless glass bifolding doors look and work in a different way to a regular aluminium bifolding door. Customers often ask us how frameless bifold doors open, and whether they are different to conventional bifold doors.

To help you understand the key visual and operational differences between a frameless bifolding door and a standard aluminium folding door, we explain how each of these products looks and operates.

Frameless bifolding doors offer virtually no visible hardware.

One of the first things you will notice about a frameless bifold is the lack of visible hardware. Compare a regular door to a frameless door, and you will notice that apart from the main door handles, a frameless bifold does not show any of the key components that enable these sophisticated doors to slide and fold.

Componentry differs on a conventional aluminium bifold door as well. Often you will often see the running gear, wheels and other components visible at the bottom of the doors. Look at the top, and you will also see the guides in the top frame. Finally, you will see two or three visible hinges per leaf connecting each door panel. You will also see the folding leaves fitted with a pull handle and a locking lever as well.

Opening and closing frameless bifolding doors.

Our single and double glazed frameless bifolding doors operate with a turn and fold or swing and fold operation. From the fully closed position the procedure to fully open and fold the doors is simple.

  1. Unlock and swing open the master door using the pull handle fitted.
  2. The master door will hinge open in the 90-degree position.
  3. Each of the remaining doors then slides along to their stop position. At this point, it can be swung open to the same position as the master door.
  4. Repeat this process for each of the remaining door panels until all are stacked open.
  5. Reverse the procedure to close the doors.

Opening and closing aluminium bifolding doors.

With a full framed aluminium bifold, there are more unlocking operations involved depending on how many leaves the doors have and how the master leaves, if provided, are configured.

To unlock hinged folding doors, the main access or locking leaf needs to be opened and then swung open. Following this, all the remaining intermediate leaves must also be unlocked with the handles provided.

Depending upon whether the doors open inwards or outwards, the doors are opened ajar. You then go to the end panel and slide the doors to their folding position, or you can use the internal handles to open each section at a time.

If the doors open in both directions, the same procedure applies on each side.

Frameless bi-folding doors offer more flexibility than other bifolds.

There are several advantages in how a frameless bifolding door opens with each leaf being independent.

  1. Partial ventilation is possible with having each leaf provide air gaps.
  2. No doors are left ajar if you do not want to open the doors fully.
  3. Frameless doors let you have more control over how many leaves you slide and fold.
  4. When fully stacked open, frameless bifolding doors take up 50% less space than regular bifolding doors.

What our customers say

See for yourself this brilliant design

“Visiting the FGC factory before a site viewing was the best decision we made. Very few of the reviewers make any mention of the apparent simplicity that disguises the cleverness and ingenuity in this way of dealing with a large size glazed opening. At the factory the finer details behind the design were explained, and

As to how we were from initial contact (were we polite)? Yes a bit abrupt especially the on site visit. Arranging installation (were we on time and on schedule) Excellent. Were we clean and tidy? Good but the windows were left uncleaned so difficult to check for scratches. VG at organising a company to deal

Mr A – Leavesden

With regards to feedback, the pre-sales advice and support from Adrian was excellent and we found it really valuable to visit the factory and see the demonstration doors. Furthermore, the installers were very professional, on time, polite, tidy, hard working and went out of their way to ensure we were comfortable operating the doors before

Delighted

Delighted with final result and extremely pleased that I decided on these ‘frameless glass doors’ over conventional bifolds. The company had no end of patience with any pre-order questions that I raised and the factory visit and visit to view an existing installation were very informative and reassuring. The team that fitted were professional, attentive

Small maintenance issue

We had a small issue with the opening door, we contacted FGC and they arranged for a team to come. They sorted the issue very quickly then cleaned the runners and door seals, fully tested the operation of the doors and carried an additional mod on the door handle. All done and dusted with an

Superb service combined with outstanding designed product

In my view, the hallmark of something well designed is simplicity combined with good looks… FGC offer this in spades. Having looked at literally hundreds of bi-folding doors, we were struck by how straightforward the FGC product is – and, as far as it is possible to eliminate the frame except around the exterior of
