Patio Sliding Doors vs. Bi-Folding Doors – Which is Right for Your Home?

Choosing between patio sliding doors and bi-folding doors is a significant decision that can impact the aesthetics, functionality, and overall experience of your living space. Both options offer unique advantages, and understanding these differences will help you determine the most suitable solution for your home. At Burgess Windows and Doors, we provide expert consultations, advice, and tailored quotations to ensure you select the best option for your specific project and lifestyle needs.

Understanding the Two Options

Bi-Folding Doors

Bi-folding doors consist of multiple panels that fold back in a concertina style, allowing for a completely open aperture. This design creates a seamless transition between indoor and outdoor spaces, making it an excellent choice for homeowners looking to maximise their connection to the outside environment.

Sliding Doors

Sliding doors operate on a track system, with large glass panels that slide horizontally over one another. Unlike bi-folds, they do not require stacking space, making them an efficient option where maintaining internal and external space is a priority. Sliding doors also tend to feature larger glass panes, providing uninterrupted views even when closed.

Key Considerations When Choosing Between Sliding and Bi-Folding Doors

1. Uninterrupted Views

• Sliding Doors: Offer larger expanses of glass with minimal framework, ensuring uninterrupted panoramic views, even when closed.
• Bi-Folding Doors: When fully open, they create a complete opening to the outdoors, but when closed, the multiple frames between panels can slightly obstruct the view.

2. Space Requirements and Functionality

• Bi-Folding Doors: Require stacking space when opened, which should be considered in relation to internal or external layout constraints.
• Sliding Doors: Since the panels slide over each other, they do not require extra stacking space, making them a more space-efficient option.

3. Thermal Performance

Both options can achieve excellent energy efficiency, particularly when specified with high-performance glazing.

• Solarlux’s Highline bi-fold doors, for example, achieve U-values as low as 0.8 W/m²K, ensuring superior insulation.
• Premium sliding doors, such as Origin OS-20 and Solarlux Cero, offer similarly high levels of energy efficiency while maximising natural light.

4. Accessibility and Everyday Use

• Bi-Folding Doors: Often come with a traffic door, allowing for easy passage without needing to fully open the entire system—ideal for everyday convenience.
• Sliding Doors: While they provide expansive openings, they do not typically include a quick-access door, meaning at least one panel must always be moved for entry and exit.

5. Frame Depth and Floor Integration

Sliding doors typically have deeper frame profiles due to their track and sliding mechanisms. This increased profile depth must be accounted for in the floor build-up and finishing requirements, particularly if a flush threshold is desired. Bi-folding doors generally have slimmer thresholds, making integration with flooring levels more straightforward.

6. Security Features

Both Origin and Solarlux doors are designed with robust security features. For example:

• Solarlux Cero sliding doors are tested to the RC2 and RC3 security classifications, ensuring high levels of resistance to forced entry.
• Origin bi-fold doors include multi-point locking systems and tamper-resistant cylinders for enhanced security.

Which Option is Best for Your Home?

Choosing between patio sliders and bi-folding doors depends on your property layout, aesthetic goals, and practical requirements.

• If your priority is maximising views and space efficiency, sliding doors may be the ideal choice.
• If you prefer a fully open transition between indoors and outdoors, bi-folding doors could be more suitable.
