Sliding patio doors in aluminium

The latest generation of aluminium sliding patio doors offers sophisticated and technically excellent products that are justifiably gaining renewed awareness with homeowners. Stronger, slimmer, more functional and better designed than ever, sliding doors are best for spectacular views, creating glass walls and a room with a feeling of more light and space.

Why choose a sliding patio door

Whilst a door with a folding operation remains popular, sliding patio doors come with features you won’t find in a bifold. The largest glass panels, the fewest visible mullions, wider and taller doors. The sliding doors now available provide multiple solutions whether as a replacement for a dated door or as part of a new build home or extension.

Find out which types of sliding doors are best suited for a variety of scenarios. Everything is considered from materials to configuration and use.

Sliding patio door buying guide

Not sure which aluminium sliding patio door is best for your project? Everything you need to know about these and other patio doors.

Buying aluminium for large patio doors remains the most popular material because no other material goes further in terms of sizes, styling options or capability and with numerous benefits over PVCu. Aluminium sliding patio doors meet many requirements. As well as being ideal for smaller spaces, they expand out to sliders for larger sizes, those required in high-level or coastal locations. They’ll also create near-frameless or minimal doors, fixed, glass or open corner designs.

For styling and design, sliding patio doors also meet many customer requirements. From a simple patio door upgrade, to finding sliding doors with the right look and feel for a new build extension. Then there are the models designed with the lightest and smoothest slide action and for the ambitious, grand sliding doors at extreme sizes creating dramatic glass sliding walls.

Advantages of a sliding patio door

Above all, when the largest glass sizes, the best views, maximum light transmission and minimal visible aluminium are required, only sliding doors meet these requirements.

The technical excellence of sliding doors, security, energy efficiency, smooth operation or multi-functional makes these perfect patio doors. They also bring all the colour advantages of powder-coated aluminium with hundreds of colours to choose from.

Sightlines are now even more important when buying patio doors, and nothing is as thin or near-frameless as a slider. Check out who makes the slimmest sliding doors. 

It’s also possible to create that desirable transition from inside to outside with a low track and threshold also available on patio sliding doors.

Types of aluminium sliding patio doors

Many of the leading aluminium systems companies in the UK now offer a sophisticated range of sliding doors with a broad spectrum of designs, aesthetics, performance and functions.

Sliding doors will usually feature flat profiles giving a clean appearance on the horizontal and vertical profiles. Ultra high-end sliding patio doors can accommodate glass panels of 9 square metres or more.

Standard sliding patio doors are available from two to six panels. They can be fitted as stand-alone doors or as part of a screen spanning one or more floors. You can even design a modern sliding door to disappear into a wall pocket as well as having a full open corner design.

Many specialist door providers even create aluminium sliding doors with virtually no limitations on the number of sliding panels available. However, when choosing new patio doors, it’s important to understand sliding door sizes, and the role these play in the design of a new extension especially.

In considering a sliding door for the home, there are four types to choose from.

Inline aluminium sliding doors

Inline sliding patio doors feature the familiar arrangement where doors slide within their frame. Inline doors come with the option of fixed or sliding panels depending on their size and configuration.

Lift and Slide aluminium doors

Lift and slide aluminium patio doors work with more sophisticated gearing and components. The door handle rotates to lift the entire door panel away from the frame and then sliding as normal. The benefit of lift and slide doors is ventilation and more flexibility as a door set.

Tilt and Slide aluminium doors

Similar to Lift and slide doors, the tilt and slide arrangement offers a tilt facility when the doors are closed for convenient ventilation.

Slimline sliding doors

Slimline aluminium sliding doors are the latest generation of door designed to provide a minimalist or near frameless appearance. Other descriptions for these types of thin patio doors are panoramic sliding doors, ultra-thin sliding doors, floor-to-ceiling sliding doors, frameless sliding doors or minimalist sliding doors.

This new breed of patio door is substantially thinner than other types of doors, yet capable of heights of up to 5 metres or more with some highly specialised products. Slimline sliding doors are even available with an automatic opening and closing action.

Deciding which sliding door type is best

Aluminium remains the best choice of sliding patio doors needing thin sightlines. Aluminium also creates pleasing steel-styled, heritage or Art-Deco sliders as well as offering an excellent solution for interior sliding doors.

Hybrid materials also provide the same functionality and high quality with an added touch of luxury and even better energy efficiency. These types of doors use low-maintenance and contemporary aluminium outside with high quality woods inside. For properties where only real wood will do, the modern range of sliding doors in full timber and other fine woods is another excellent solution in the right installations.

PVCu patio doors today are better engineered and more reliable than even but still come with more bulky sightlines and smaller size capability, yet are very affordable.

After a lot of research to find doors that would meet our unusual size requirements and feeling increasingly uncertain about the best way to spend our small budget, I stumbled on the ATS website, and I'm so glad I did!

I've been so confused about how to achieve the look I'm after, and going round in circles with various window/door companies, trying to get away from the huge chunks of plastic currently around my windows. I didn't expect an email to a company found through a Google search to really help - but I was desperate, so I tried. I'm SO glad I did. Finally I have clear explanations from ATS of where I've been going wrong, exactly what I'm looking for, and a list of local companies that might be able to provide it! The response has excelled my expectations and I feel as if I'm finally inching closer to a home with which I'll be happy and comfortable: thank you.

We are looking to replace some old UPVC patios doors with aluminium ones. The ATS website is a great source of advice in an area where clear information is sorely lacking. Having used the website, I then followed this up with a number of specific questions relating to our search, and Nick came back very quickly with clear, detailed and very useful advice.I have been very impressed with both the website and with Nick's advice. My only regret is that I didn't come across ATS before replacing various windows in 2021 - I'm sure it would have saved me a lot of grief and money! Thanks again Nick.
