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.
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.

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.
