Choosing the right external doors for your home can feel confusing, especially when you’re weighing up French doors versus patio doors. Both types of doors flood your living room with natural light and create a seamless connection to outdoor spaces, but they work in quite different ways.
Understanding the difference between French doors and patio doors will help you make the best choice for your home, whether you live in a period property or a modern new build. Let’s break down what sets these popular door types apart.
What are French doors?
French doors are traditional double doors that open outwards or inwards on hinges. Each door sash features expansive glass panels from top to bottom, creating an elegant, classic design that’s stood the test of time.
These doors typically consist of two equal-sized panels that swing open from a central point. You’ll often find them in traditional homes, though they work beautifully in contemporary homes too. The larger glass panels allow plenty of light to pour through while maintaining that timeless look.
At Boston Trade Frames, we offer French doors in both uPVC and aluminium frames, with options for double glazing or triple glazing depending on your thermal efficiency needs.
What are patio doors?
Patio doors is actually an umbrella term covering several types of doors designed to connect indoor and outdoor areas. The most common type of patio door is the sliding patio door, which operates on a track system rather than hinges.
Sliding doors offer smooth operation and take up minimal floor space since they don’t swing in or out. They’re a popular choice for modern homes where maximising space matters.
Other types of patio doors include bifold doors (or fold doors), which concertina back to create a wide opening. These are perfect when you want unobstructed views and a genuine indoor-outdoor feel.
What’s the main difference between French doors and patio doors?
The key difference lies in the opening mechanisms. French doors swing open on hinges, while sliding patio doors glide horizontally along tracks. This affects how much space you’ll need and how the doors interact with your room layout and outdoor areas.
Design and aesthetics
French doors bring a classic, elegant feel with their symmetrical design and multiple panes of glass. They suit period homes wonderfully but can also add character to contemporary spaces. The slimmer frames on modern aluminium French doors create slim sightlines while maintaining that traditional door aesthetic.
Sliding patio doors offer a minimalist look with larger glass panels and fewer interruptions. They’re brilliant for modern homes where clean lines matter. The slim sightlines of aluminium patio doors particularly suit contemporary design.
Functionality and space requirements
French doors need clearance space to swing open – something to consider if you’ve limited floor space inside or tight outdoor spaces. However, they provide excellent ventilation when both panels are open.
Sliding patio doors win on space-saving. They need no swing radius, making them the better option for compact areas. The wide opening of bifold doors creates an even more dramatic connection between rooms and gardens, though they’re typically the more expensive option.
Natural light and views
Both door types flood rooms with natural light, but there are subtle differences. French doors have a fixed frame down the middle, creating a striking contrast between the two panels.
Sliding doors often feature large panes of glass with minimal frames, offering more uninterrupted views. This makes them brilliant for showcasing garden vistas or if you simply want maximum light.
Energy efficiency and security features
Modern versions of both French and patio doors perform excellently on thermal efficiency. Quality double glazing or triple glazing keeps heat in, while weather resistance protects against the British climate.
Security features have improved dramatically across all external doors. Multi-point locking systems come standard on both types, giving you peace of mind. Aluminium frames particularly offer robust security while being low maintenance.
