If you’re thinking about upgrading your home, French doors might be exactly what you need. They’re not just pretty to look at, they help change the way you use your space, bringing in more light, improving airflow, and making the most of Perth’s incredible climate.
Perth Window & Door Replacement Company has been helping local homeowners choose and install the right doors for nearly 40 years. We’ve seen first-hand how the right French doors can completely transform a home, whether you’re renovating an older Perth home or building something brand new.
Let’s walk through everything you need to know about French Doors for your Perth home.
What are French doors?
French doors are two-hinged doors, either as a single leaf or a pair, featuring large glass panes that open inwards or outwards to create a wide, unobstructed opening. Unlike sliding doors, both panels swing open, giving you full access to your outdoor area.
Modern versions have come a long way. Our French doors are made with aluminium frames with double glazing and low-e glass for energy efficiency. The frames are slimmer now too, so you get more glass and less bulk.
They’re popular because they suit almost any home style, whilst letting in loads of natural light.
Where in your home do French doors work best?
The beauty of French doors is their versatility. Here are the spots where they really shine.
Living room to alfresco or patio
This is the classic setup. Perth gets around 265 days of sunshine a year, so why not make the most of it? French doors from your living area to the patio create that seamless indoor-outdoor connection everyone’s after. You can throw the doors open for a barbecue or keep them closed with the view still intact.
Master bedroom to balcony or courtyard
If you’ve got a balcony or small courtyard off your bedroom, French doors let you capture cross-ventilation on those warm Perth nights. They also make the room feel bigger and brighter during the day.
Internal French doors between rooms
Not all French doors lead outside. You can use them between your lounge and study, or dining room and kitchen. They borrow light from one room to another, whilst still giving you some noise separation when you need it.
Single vs double French doors: choosing the right configuration
You’ve got two main options here: single or double.
Single French doors are space-savers. They’re typically 820 to 920 mm wide, perfect for narrow laundries, side entries, or smaller bedrooms. One door swings open, giving you a decent-sized opening without taking up too much room.
Double French doors are the more popular choice. They range from 1200 to 1800 mm wide and offer a clear opening of 1.5 to 2.4 metres when both doors are folded back. That’s a big, open space that makes moving furniture easy and creates a real sense of flow.
Aluminium French doors: the modern, low-maintenance option
If you’re leaning towards external aluminium French doors, you’re making a smart choice for Perth’s climate.
Aluminium frames are slim (around 45 mm compared to timber’s 65 mm), which means you get more glass and better views. They’re also low-maintenance. The powder coating withstands WA’s coastal salt spray without flaking or corroding, meeting the AS3715 standard for durability.
If you’re in a bushfire-prone area, aluminium French doors paired with toughened glass can meet BAL-29 compliance. And with thermally-broken aluminium frames, you’ll easily hit the NCC’s 7-Star energy requirements that came into effect in WA back in May 2025.
They’re tough, they look great, and they don’t need repainting every few years.
Benefits of French doors beyond good looks
Sure, French doors look fantastic. But there’s more to them than aesthetics.
More natural light
French doors can deliver up to 25% more glazed area than a standard hinged door of the same width. That’s a noticeable difference in how bright your home feels.
Indoor-outdoor flow
This is huge in Perth. The ability to open your living space straight onto the patio or garden aligns perfectly with how we live here. It’s also one of the top renovation trends in Australia right now.
Energy savings
High-performance double-glazed French doors can reduce heat gain by 49% compared to single glazing in Perth’s climate zone 5, based on NCC 2025 energy modelling. That means a cooler home and lower energy bills.
Aesthetic versatility
They work with any style, from heritage homes to minimalist new builds. You can customise the colour, the glazing, and even add colonial bars if that’s your thing.

How to install French doors (DIY vs professional)
Installing French doors isn’t a simple weekend project. Here’s a quick overview of what’s involved.
You’ll need to measure the rough opening (allowing 10 mm clearance on all sides), remove the old frame, and check for rot or termite damage. Then comes flashing and sill pan installation per AS2047 water-ingress rules, inserting the pre-hung door set, squaring it with packers, and screwing through the jambs into the framing.
After that, you’ll seal gaps with foam or backer rod, fit architraves, adjust the hinges, install the multi-point lock, and finish with weather seals.
Can you DIY it? Maybe, if you’ve got solid carpentry skills and the right tools. But most homeowners are better off hiring a professional. Our team at Perth Window & Door Replacement Company holds WA Building Commission licences and has decades of experience installing doors in Perth. We’ll make sure the job’s done right the first time, with proper sealing and alignment.

How to install French doors: can I DIY or should I hire a professional?
Installing French doors involves measuring, removing old frames, flashing, squaring the new frame, sealing, and installing hardware. Whilst experienced DIYers might manage it, professional installation ensures proper sealing, alignment, and compliance with AS2047 standards. Hiring a licensed installer also gives you warranty protection and peace of mind.
How to secure French doors against break-ins?
Secure French doors with multi-point mortice locks, 20mm-throw bolts on the passive leaf, toughened or laminated glass (minimum 5 mm), and security screens like Invisi-Gard. Use 3-inch stainless screws through hinge plates and consider smart locks with keypad or Bluetooth access. Properly specified French doors can be as secure as any entry point.
