The types of patio Door
Patio doors come in a few main popular styles, each with its own charm and benefits. Let’s have a quick look:
Sliding Patio Doors:
These are a modern classic, with large glass panels that slide along a track. They’re great for letting in lots of natural light and giving you lovely unobstructed views. Plus, they don’t take up extra room to swing open, so they’re ideal for smaller spaces. Brands like Andersen and Grandsesa offer excellent sliding options.

Hinged or French Patio Doors:
These doors swing open like a regular door and bring a touch of timeless charm and sophistication. They can create a grand entrance to your outdoor space and often have wider frame profiles. They can be more secure too, thanks to their sturdy materials and locking mechanisms. Marvin and Pella are well-regarded for their hinged patio doors.

Bifold Patio Doors:
These are becoming increasingly popular as they create a really wide opening, giving you a fantastic seamless transition between your indoor and outdoor areas. The panels fold back on themselves, offering a real wow factor.
Multi-Slide Patio Doors:
Similar to sliding glass doors, but with multiple panels that can slide open and stack, giving you expansive views and wider access to your outdoor space.
Choosing the Right Material for Your Patio Doors
The material your patio door is made from will affect its look, how much it costs, how energy-efficient it is, and how much maintenance it needs. Here are the main contenders:
Vinyl:
Often a budget-friendly option, vinyl doors are durable, energy-efficient, and need very little maintenance. They also come in a good range of colours. However, they can expand and contract with temperature changes, which might affect how smoothly they operate over time.
Fibreglass:
These doors are known for being strong and very energy-efficient as they don’t transfer heat or cold easily. They’re also resistant to warping, rotting, and mould. While they might be a bit pricier than vinyl, their durability and low maintenance can make them a great long-term investment.
Aluminium:
With their sleek, slim frames, aluminium doors offer a modern look. They’re sturdy and lightweight, and they’re a good choice for coastal areas as they’re corrosion-resistant. However, aluminium conducts energy well, so it might not be as energy-efficient as vinyl or fibreglass unless it’s thermally improved.
Wood:
Wooden patio doors offer a timeless and elegant look and are naturally insulating. However, they typically require more maintenance than other materials to keep them looking their best and prevent issues like rot and warping.
What do I need to consider when buying patio doors?
Before you take the plunge, it’s a good idea to have a think about what you really need and want from your patio door. Consider these questions:
- How much space do you have? Do you need a door that doesn’t swing outwards, like a sliding door? Or do you have room for a grand swinging entrance?
- What’s your budget? Prices can vary quite a bit depending on the style, material, brand, and any custom features. Vinyl tends to be more affordable, while materials like wood and bifold designs can be more of an investment.
- How important is energy efficiency? If you’re keen to keep your home warm in winter and cool in summer without racking up huge energy bills, look for doors made from insulating materials like fibreglass or vinyl, and consider double or triple-pane glass.
- How much do you value indoor-outdoor living? If you want truly wide-open spaces, options like bi-fold doors or multi-sliding doors may be just what you need.
- What about security? If security is a big concern, French doors are often considered the most secure due to their sturdy construction and locking mechanisms.
- What is your local weather like? If you live in an area with high winds, such as a coastal area, French doors are actually very suitable. Grandsea offers impact patio doors with wind resistance rating certification. For cold weather, well-insulated wood, aluminum-clad wood or fiberglass multi-layer glass sliding doors or French doors are your best choice.
how to identify a door or window manufacturer?
If you’re not sure who manufactured your existing patio door, have a good look for a label or tag. It’s often placed at the top or bottom of the door. You might also find a logo stamped on the hardware, like the handles or locks, or on the frame, especially with sliding doors.
What kind of designs work the best for patio doors?
For good reason, sliding doors, French doors, and bifold doors are often the most popular choices. Sliding doors are great for their space-saving design and the amount of natural light they let in. French doors offer a more traditional and elegant style. And bifold doors are the go-to if you want that fantastic wide opening to blend your indoor and outdoor spaces.
Repair or Replace your patio door?
Sometimes a patio door might just need a bit of TLC, but other times it’s better to go for a full replacement. If your door is old, damaged, draughty, or difficult to open, it might be more cost-effective in the long run to replace it with a new, more energy-efficient model. Replacing a standard-sized door can sometimes be easier and even less expensive than trying to repair an old or custom one.
What is the cost of patio doors?
The cost of a patio door can vary quite a bit. A basic sliding glass door might start from around $400, but more elaborate hinged doors or those with premium materials can go up to $3,000 or even more. Factors that affect the patio door price include the brand, the material, the size, the type of glass (like double or triple-pane), and the colour. Generally, vinyl tends to be less expensive than aluminium, aluminium cheaper than fibreglass, and fibreglass less than wood. Bifold doors are often the priciest due to their more complex design. Don’t forget to factor in the cost of installation too, which can add a few hundred dollors to the bill.
