Bi-folds and French doors are regularly found at the back of people’s homes, leading out onto their garden. But despite often serving the same purpose, their features differ significantly. Both are excellent choices, however we’ve had a closer look at them, to help you determine which is right for you.


Available in uPVC and aluminium, our bi-folding doors feature, but are not limited to, these characteristics:

  • aluminium bi-foldsBi-folds allow for maximum light intake into your home. Emerald can fit them up to 7m wide and 3m high, turning former walls into large passages of light.
  • When opened, the panels on bi-folding doors stack to one side, creating a vast opening. This ensures for a seamless connection between your home and the garden.
  • Choose from 2 to 7 panels and 38 different opening configurations, allowing for incredible versatility.
  • Emerald can apply any RAL colour to a set of bi-folds, including dual colour options.
  • Bi-folding doors feature a level threshold, meaning there is no lip to step over when moving from the inside to the outside of your home.

French doors

Constructed from high quality uPVC, French doors from Emerald possess the following features:

  • French doors with georgian barsuPVC is a naturally insulating material, which means they will retain heat in your home very effectively. This means they’ll shave money off your energy bills.
  • French doors usually consist of two doors that are hung so they can be opened inwards and outwards. When opened, your home will be ventilated significantly.
  • With an elaborate range of RAL colours and woodgrain finishes to choose from, they can be adapted to suit your property and tastes.
  • With a design rooted in tradition, they’re perfect for achieving a luxurious finish that nods to the past. This also means they tend to be better suited to older style homes.
  • French doors can complement other traditional features present on a home, such as flush sash windows. Flush sash windows are present in the Residence collection, which we also supply.
  • Plenty of light is able to make its way into your home, thanks to the presence of large portions of glazing and slim frames.

Which is best for you?

If your main concern is creating a beautiful open space, bi-folds are the right option for you. They allow for maximum light influx and ventilation. The classic and elegant design on French doors means they’re perfect for traditionally styled homes, however bi-folding doors are becoming increasingly popular on such properties.

Whilst either set will make a superb addition to your home, it’s important to choose a set that is more suited to your desired purpose.
