Our aluminium bi-folding doors can open up entire walls offering stunning and near uninterupted views of your outside space. With any combination from two to seven panels, and a maximum width of 7m, we are certain there is a bifold door configuration to suit your home. The advanced insulation properties of thermally broken aluminium mean that our bifold doors are energy efficient, helping to keep your energy bills down whilst being kinder to our planet.

The minimum recommended width for bifold doors is 1400mm (4.7 ft), however, this is the minimum width for a set of bi-folding doors with 2 door panels. To meet the recommended minimum, an individual door panel needs to be no less than 700mm (2.2 ft). Emerald recommends that you don’t opt for anything much smaller than this, or the doors might bind upon closing. Additionally, this might also prevent you from having a usable traffic door. A traffic door is a conventional door that operates independently so you can transition between areas without moving the whole set of bifold doors.

What is the maximum width for bifold doors?

The maximum overall width for a set of bifold doors is 7m. It’s worth noting that the frames should take up approximately 5 to 10cm, so it’s important that you take this into account when calculating the expected width of the doors. Our aluminium frames offer slim, sleek, sightlines whilst being inherently strong and extremely energy efficient. You also have a huge variety of choice when it comes to colours and finishes. Black aluminium bifold doors offer a contemporary, minimalist look, whilst white offers something a little brighter and more traditional.

What is the minimum height for bifold doors?

Bifolds can be manufactured to a minimum height of 1600mm (5.5 ft). Much smaller than this, however, and they’re considered a folding window. Conventional doors are around 2100mm in height so bear in mind that 1600mm is half a metre shorter than this. Otherwise, any taller inhabitants or guests might struggle to get through them!

What is the maximum height for bifold doors?

A set of bi-folding doors is available at a maximum height of 3m. Although, Emerald does not recommend manufacturing a bifold door to both the maximum width and maximum height. This may negatively affect both aesthetics and functionality.

What configurations are available with bi-folding doors?

grey aluminium bifold doors opening Up to 38 different configurations are available to choose from so we’re confident there is a bifold door solution to suit your home. The number of panels you can have will depend on the size of the aperture.  If you’re looking to quickly move between areas of your home, a set of bifolds with 2 panels is not the most convenient. This is because there’s no way of incorporating a traffic door. So, unless you have another door that is convenient to use, opting for 3 panels or more is wise.

In terms of opening, you can choose whether the doors open inwards or outwards. All doors can either fold entirely to the left, or to the right, or they can be split in the middle to fold both left and right.

There are also four different threshold options available to choose from, including ultra-low, to suit a variety of access requirements. Bi-folding doors also have a wide choice of handles, which are available in a number of finishes, so you can customise your doors down to the very last detail.
