Bi-fold doors are very popular, particularly as patio doors, as they are a great way to connect the interior of your home with your outdoor space. In this article, we’ll look at the pros and cons of bi-fold doors so that you can make an informed decision if this is something you are considering for your home.

PROS of bi-fold doors

Expansive Openings: Bi-fold doors are sliding doors that create a wider opening than a standard door. They are great when entertaining in the summer months as they allow an unobstructed view of your exterior and free flow between spaces.

  • Maximised Light: Double-glazed bi-fold doors are thermally efficient and fill your space with lots of natural light.
  • Space Optimisation: Bi-fold doors are a great space-saving option. They slide to one side, blurring the lines between the inside and outside of your home, unlike traditional patio doors.
  • Aesthetic Appeal: A bi-fold door is a popular and modern choice for external doors leading to your garden area and is also great for internal living rooms.
  • Closet Delights: Bi-fold doors can also be used inside your home. These folding doors are a great option for tight storage spaces or wardrobes as they maximise accessibility.
  • Interior Elegance: A bi-fold door is a great way to separate rooms when needed, such as a kitchen and living room while maintaining an open plan feel.
  • Versatility: There are many different materials and styles available for bi-fold doors, so it’s easy to match your home decor and living needs.

CONS of bi-fold doors

  • Security Concerns: It could be argued that a bi-fold door is a security concern, due to the high number of glass panels compared to other doors and its sliding door system, that could be lifted from its tracks. While older doors may be vulnerable, newer bi-fold doors have multiple locking points and strong glass.
  • Cost Factor: Bi-fold doors can be more expensive than other doors and it’s worth consulting a few companies before settling on one to install them. It’s a personal choice, but many believe that the benefits outweigh the cost.
  • Weather Vulnerability: Bi-fold doors can be vulnerable to weather-related problems, such as water infiltration, reduced wind resistance, and material degradation over time. However, with regular maintenance, this should not be a problem.
  • Privacy Concerns: Although sliding doors can let in a lot of natural light, they can also require window treatments for privacy if used in areas such as bedrooms or bathrooms.
  • Sound Transmission: Noise can travel easily through doors, impacting room separation. However double glazing can reduce this.
  • Installation Complexity: A bi-fold door needs to be installed by a professional and isn’t something you should attempt yourself.


Installing bi-fold doors is a great idea for tight spaces in your home, such as wardrobes or cupboards. It is also excellent for bringing the outside in, which is great for entertaining especially when fully opened. They are energy efficient, low maintenance, and can potentially increase your property value.
