uPVC Sliding Doors vs Bifold Doors: Which is Right for You?

By digiadmin | 24 July 2025 |

When it comes to enhancing your indoor-outdoor living space, the choice often comes down to uPVC sliding doors or bifold doors. Both offer sleek aesthetics, smooth operation, and fantastic garden views—but which one is the better fit for your home? In this guide, we compare the key features, benefits, and differences to help UK homeowners make an informed decision.

What Are uPVC Sliding Doors?

uPVC sliding doors consist of two or more large glass panels that slide horizontally along a track. They are ideal for maximising views and saving space, particularly in smaller areas or rooms with furniture close to the doors.

Benefits of uPVC Sliding Doors:

Uninterrupted Views: Large panes offer panoramic garden views.
Space-Saving: Doors slide rather than open outward or inward.
Smooth Operation: Effortless gliding mechanisms for ease of use.
Energy Efficiency: Double glazing and weather seals keep heat in and draughts out.
Low Maintenance: uPVC frames resist weathering, warping, and fading.

What Are Bifold Doors?

Bifold doors are made up of multiple panels that fold and stack to one or both sides of the opening. While bifold doors can be made from uPVC, they are also commonly found in aluminium.

Benefits of Bifold Doors:

Wide Opening: Offers nearly 90% of the door space as a clear opening.
Flexible Design: Panels can fold inward or outward depending on preference.
Modern Appeal: A stylish feature for contemporary homes.
Ideal for Entertaining: Creates a seamless indoor-outdoor transition.

Head-to-Head Comparison

uPVC Sliding Doors

View: Offers unbroken, large glass panes for panoramic views.
Opening Width: Typically opens to approximately 50% of the overall width.
Space Efficiency: Excellent choice for compact areas—panels slide rather than fold.
Ease of Use: Simple sliding mechanism, easy to operate.
Maintenance: Very low maintenance with fewer moving parts.
Cost: Generally more affordable than bifold doors.

Bifold Doors

View: Multiple frames may interrupt the view slightly.
Opening Width: Can open almost the entire width (up to 90%).
Space Efficiency: Requires space for stacked panels when open.
Ease of Use: Slightly more complex operation with multiple hinges and tracks.
Maintenance: Moderate, due to more components and folding mechanisms.
Cost: Typically higher, especially with custom configurations or aluminium frames.

Which Door Is Best for You?

Choose uPVC Sliding Doors if you want uninterrupted views, have limited internal space, or prefer a sleek, minimalist look.

FAQs

Q1: Are uPVC sliding doors more energy-efficient than bifolds?
A1: Both sliding and bifold uPVC doors are designed with energy efficiency in mind, typically using double or triple glazing and insulated frames. However, sliding doors often have fewer panels and sealing points, which can slightly enhance their thermal performance by reducing potential draughts and heat loss, especially in exposed areas.

Q2: Which is easier to maintain—sliding or bifold doors?
A2: uPVC sliding doors are generally easier to maintain than bifold doors. Their design involves fewer moving parts and a simpler sliding track, reducing the chance of mechanical issues. Regular cleaning of the tracks and occasional lubrication are typically all that’s needed to keep them functioning smoothly.

Q3: Can both types of doors be used in smaller homes?
A3: Yes, both options work well in smaller spaces, but uPVC sliding doors are particularly suited for compact homes. Because they don’t require inward or outward clearance to open, they maximise usable floor space and provide an uninterrupted view when closed—ideal for creating a more open, airy feel in tighter rooms.
