Glass sliding doors vs french doors: Which are better?

Patio doors connect indoor and outdoor living spaces and so become an important, yet often undervalued, part of designing a home. When it comes to choosing between 

1. Form

How the door design suits your home’s style and aesthetic.

2. Function

Whether the door opens a space, closes it off, lets in enough light and is secure.

3. Feeling

Your personal preference in terms of finishes, designs and features.

Before diving into the pros and cons of each style, let’s look at the differences between glass sliding doors and French doors.

Glass sliding doors

French doors


Use less space

Neater design style

Removes the barrier between indoor and outdoor living

Unobstructed views and more natural light

Sliding screens can be used for pest protection

Customisable to suit the size of the entry

Can position furniture in front of the fixed panel


Opening width is limited to how far the panel can slide

Slower access

The seal isn’t as airtight and less energy efficient

Debris can collect in the track, requiring cleaning

 A wider opening requires more frames and hence, less glass

French doors: Pros and cons


Classic design style suits traditional architecture

Faster to open

Attractive design creates a feature or focal point

Create a tighter seal for energy efficiency and security

 Able to create a large opening when both sides are open


Create unusable space when opened

Width of the doors has limitations

Depending on design the outside view might be reduced

So, which is better?

Let’s go back to the considerations of form, function and feeling. While sliding glass doors take up less space, offer more natural light, and effectively double living space by bringing outside in, French doors have a certain je ne sais quoi making them a popular feature in traditional design.


Energy efficiency is key in modern homes. French doors have the edge by using a double rubber seal and creating an airtight seal that 


While both are secure because of the Grade A safety glass used and frames reinforced with galvanised steel, French doors are more secure due to the double rubber seal and the 5-point locking system designed for the door. French doors have 5-points where the bolts engage and lock compared to 3 on sliding doors. Both can be fitted with security screens for an added safety measure.
