Comparing sight lines on bifolding doors

Bifolding door sightlines are one of many considerations when choosing a new, quality folding sliding door for your home.  To help you understand this feature found in all types of doors, we explain more about it as well as what to consider. We also compare our best selling frameless doors with some of the best-known brands.

Only our frameless sliding and fold doors come with virtually no sight line and no visible mullion.

Everything you need to know about bifolding door sightlines.

First of all, the definition of a sight line is the amount of non-glass material, blocking the line of sight through any door in the closed position.  Many good brands of bifolding doors now offer reduced sightlines thanks to the better design.

Secondly, every door, whether aluminium, PVCu, timber or even our frameless doors, require a frame. One frame houses the glass units; the other frame is the perimeter frame fixed to your house.  The outer frame is always visible – as every door needs this for rigidity, security and weather performance.

Third, is the visible frame you see around the glass.  In a conventional bifolding door, every panel is independent. As a result, when looking at a closed set of doors, you see visible mullions.  The more panels in your bifold, the more mullions you see. This is the sightline.

Therefore, while bifolding doors are outstanding as a patio door, opening up your home, in winter, they remain closed. Consequently consider that the thinner the mullion, the more glass you get and the better views through the glass.

Comparing bifolding door sightlines on aluminium bifolds.

At FGC, not only do we have a lot of bifolding door experience, but we also know other products too.  Our patented frameless system is a premium quality door.  With no visible mullions as well as no aluminium, only our door offers you the slimmest bifolding door sight lines. Therefore,  if you’re comparing our doors to other top brands as you do your research, we make it easy for you to compare bifolding door sightlines.

Of course, there are other brands of bifolding doors, but we are showing you the premium brands allowing you to compare on a like-for-like quality basis.

Four Reasons why frameless doors are the better bifolding doors.

If the sight lines on your bifolding doors matter, there are more great reasons to choose an FGC frameless slide and fold doors.  Our unique mullion design provides benefits and a better bifolding door in other areas too.

No unsightly door hinges.

Any aluminium, upvc or timber concertina style bifolding door needs hinges to connect the door panels. As a result, you get not only visible mullions but also visible hinges.  Inside the doors, you also get two handles. One is a pull handle the other is a locking handle.

Our frameless system uses our roller system with durable guides meaning the doors do not require any intermediate hinges.

Better views through the glass.

Look at the double glazed units in your home, and you will see a white,  silver or black ‘spacer bar’.  A spacer bar holds the two panes of glass together as well as providing energy efficiency to the overall window or door.  Thermal performance in glass and windows help lower your energy bills.

Our doors also use thermally enhanced spacer bars. However, at the door mullion, we use glass instead of plastic or metal.  As a result, we offer better clarity through our already minimal sight lines.

Thinner aluminium than other bifolding doors.

As well as offering you no visible mullions and the best aesthetics, our doors also have thinner aluminium in the critical areas.  Our door rails and our outer frame is smaller than most bifolding doors on the market.

Furthermore, our doors are also narrower depth profiles too.  So not only do you get thinner doors when closed, but you also get neater stacking doors when open. Our fully folded panels take up less space than other brands.

A lower bifolding door threshold.

The thinner bifolding door sightlines and thinner frame also allow us to design a lower threshold.  Even better is our threshold is lower than other brands’ threshold and comes with a weather rating.  Check out most other bifolding door thresholds marketed as ‘low’, and you’ll often see a disclaimer saying there is no weather rating or that threshold suggested for internal use.

Our unique patented product offers all the benefits of a bifolding door such as transforming your living space and enhancing your home.  They are energy efficient, secure and weather resistant.  Our doors also give you better views thanks to slimmer frames and bigger glass panels.  They also have the best sight lines.

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.

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.
