Given that Bifolding doors are popular with homeowners because of the views afforded by bigger glass panel, it does beg the question why a homeowner would ask for bifolding doors with Georgian Bars. After all, even in the closed position, bifold doors still give great views of the outside space.
Bifolding doors with Georgian bars
Are aluminium bifolds available with applied glazing bars? You may struggle to source them.
Some properties lend themselves very well to windows and doors with Georgian effect inserts or Astragal bars applied to the glass directly, inside and out.
Traditional properties frequently feature windows, French doors and even bifolding doors with decorative bars, leaded glass or feature glazing.
There is no reason why Georgian bars (those plastic bars between the panes of glass) can’t be applied to any product, however with Astragal bars, (applied directly to the glass), an aluminium bifolding door can make things a little more complicated.
If you are being asked for an aluminium bifolding door with any applied glazing bar and finding it hard to source there are some reasons why.
In aluminium, bifold doors with glazing bars are hard to source.

One of the issues with bifolding doors is finding compatible glazing bars from the range of after-market products available. These profiles are designed for windows and doors but often difficult to source for bifolding doors.
In aluminium, glazing bars have to be notched or machined where horizontal bars meet vertical. The bigger problem is at the edge of the doors where the bar meets the profile on one side and the glazing bead on the other. Not all generic glazing bars work with all bifolding door systems. One solution is for the bifolding door company to extrude its own glazing bar. However, given the relatively small demand for aluminium bifold doors with glazing bars, this is quite a large investment to make in extrusion dies and tooling.
One solution for aluminium glazing bars in bifolding doors is a flat aluminium trim applied to the inside and outside. Companies specialising in stock extrusions sell a variety of flat bar pieces. These can be powder coated and applied to the glass with suitable glazing tape or another method if desired.
For bifolding doors with glazing bars, timber is the best solution.
For bifolding doors requiring astragal bars, timber doors may be the better solution. The way timber doors are made makes glazing bars easier.
With timber, you can take a large piece of wood and machine it to achieve the glazing bar required. Aluminium profiles need dies to be made and the extrusion presses to create the profile. Once extruded it cannot be altered.
Another option is to use the Georgian bars inside the double glazed unit, but this may not be to everyone’s taste in a door.
