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.

FGC installed a two-panel frameless glass door at our property yesterday. Wow!! the installation is exactly as discussed, and was carried out by two of FGC's team members who were so professional and courteous. They were excellent, and we have no hesitation in recommending FGC and their team to anyone considering such an installation.We are delighted with the installation, and very pleased we chose FGC.Well done FGC!!

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.

What our customers say

An underestimated product

After visiting a NT stately home which had a glass porch entry I asked fgc to see if they could do one for us. I had the vestiges of a porch with brick sides but no front. The installation made the entrance a feature which is declared up market and interesting. It is a halfway

A great job

Hi,
I would like to say that your work crew were really nice people and did a great job !!

Fantastic aftercare service!

I had an installation of 4 doors in December 2018. During the cold snap in January this year the outside glass handle cracked. I contacted Sara in customer support and the handle was replaced free of charge by Liam and Alf who did the job quickly and professionally. They also checked that all the doors

After Sales Customer Service Exceptional

Thank you for your excellent after sales customer service it is exceptional.
The track coating was repaired to a very high standard by Dan the “Magic Man”, he is very professional and his work is very good, to the point that it is difficult to spot where the repair has been made.

MR VH, Essex

The service I received from FGC was professional and prompt from the initial on site survey through to installation and completion. Added to this the finished product has exceeded my expectations. It has enhanced my home with style and individuality, and enabled me to make use of the space in a way that is ‘unique’.

Mr P – Aylesbury

We have been very happy with the service you offer and indeed the product. We found the office responded promptly and the delivery was swift and when promised. The fitting staff were professional, polite and unintrusive. We would be very happy to let people look at our installation. 20150724

Our Frameless Glass walls

Putting a frameless glass walls between our South facing lounge and dining room conservatories was one of the best things we have ever done in our house. When shut, they keep out the cold in winter and, most importantly, the heat on very hot summer days. When open during sunny winter days, the heat warms

First class

We moved last year and wanted to maximise the view right through from the rear to the front of the building, overlooking the river. After much searching we found FGC, who installed internal glass doors between the rooms. FGC were very efficient and although we are in the North they sorted out a subsequent small
