Bifold doors are a popular choice for those wanting to create a wow-factor indoor outdoor space in their home. These doors are a great way to flood a room with natural light and provide great views of the surrounding landscape, but there is a lot to be considered to ensure you are satisfied with your installation.

One of the main considerations is your choice of threshold.

What is a Threshold?

A threshold is the track which guides the movement of your bifold doors. There are two types of threshold – weathered and non-weathered.

A weathered threshold features a small solid lip on one side of the track, while a non-weathered threshold will sit flush with the floor.

Which Threshold Should I Choose?

Non-weathered thresholds are great options for internal bifolds or exterior doors that are sheltered from the elements, as they sit completely flush with the floor.

From a decor point of view, this helps to ensure that interior spaces seem cohesive, but from a more functional point of view, it eliminates any trip hazard and ensures the home is fully accessible to those with mobility concerns.

It is a good idea to opt for a weathered threshold for exterior bifold doors as the raised lip will ensure that the doors are both wind and watertight, preventing any water ingress or leaks.

Tips for Creating a Great Indoor Outdoor Space

If a non-weathered threshold isn’t the right option for your external bifold doors, then you can still create a wow-factor indoor outdoor space with the following tips:

  • Bringing in light from different directions with the addition of a skylight or bifold doors will create the illusion of being outdoors while also being protected from the often unpredictable British weather
  • Choose the same floor finish inside and out. This will make the space appear seamless. The key is to choose a material that is suitable for both indoor and outdoor applications
  • Use plants from the garden inside your home, or choose garden furniture that complements your indoor furniture – this works to trick the mind that both areas are part of the same space.
