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.

image4

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.

Excellent service and product from FGC.I have a glass-box conservatory, built with structural glass about 20 years ago. The 2 sliding doors needed replacing, along with 2 side panels, and I contacted dozens of companies selling conservatory doors and none of them were prepared to install their doors because of the perceived risks of working with structural glass.Then I found FGC who, with no fuss at all, carried out a survey, provided a very reasonable quote for the doors/panels and then installed the doors/panels on the agreed date.Communication with the FGC office was always quick and easy. The surveyor and installation team were efficient and courteous. The product works beautifully.We can now use our conservatory again. Thanks FGC.

FGC installed a two-panel frameless glass door at our property yesterday.

We purchased a beautiful Origin sliding door and side window from FGC. FGC installed the sliding door and window on time, however the sliding door did not fit correctly. Issues can happen. FGC made the process of re-surveying and re-installation very simple. FGC is a very pleasant and professional company to deal with. We are very happy with their service and would strongly recommend them.

Excellent planning and product advice. All the staff were polite courteous and friendly.On the day of the installation, the team arrived bang on time -we live in Wales so a long drive from Kent! They had the job done by lunchtime (fitting a sliding patio door) and I have to say that on first impression of the unit, it looks and feels like solid quality.

We had a 5m stretch of these wonderful doors installed several years ago and have been very happy with the uninterrupted view of the garden that they allow from the living room. They are admired by every tradesman who sees them. A minor problem we experienced with water ingress last year was promptly and effectively resolved, and the doors were serviced for free at the same time.

Initial contact
FGC were very informative over the phone and were quick to arrange an appointment for us to see the doors at their showroom. They also gave a number of contacts for us to visit to view existing installations. Installation
FGC installers arrived on time and completed the installation quickly and tidily.

Hugely impressed by your level of service.

I just wanted to say that I remain hugely impressed by your level of service. The two chaps who came out to service our doors were once again marvellous.  They are very polite and clearly very skilled. It’s very easy these days to complain and sometimes it’s nice to pass on credit where it is

Luff – Caernarfon

As to how we were from initial contact (were we polite)? Staff were polite and prompt in answering telephone questions. There were technical problems with our installation and staff were open and discussed options and were polite. The fitters were surprised at the distance they had to travel to reach us each time, although we

Always Polite

Re delivery, there was an initial hope that you might be earlier than the 6-8 week lead time, but once that wasn’t going to happen, you gave us a date, and were then able to bring it forward a couple of days to fit around our holiday schedule, which was great.  Guys turned up at

Great post installation service

In addition to the quality of the product – which is stunning, and head an shoulders above anything else on the market – the ongoing support and maintenance is impressive. I had a small issue with the doors recently and their maintenance team came back within 48 hours to resolve everything whilst giving the doors
