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.

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.

Which sliding door is right for you?

Any current patio door product should work when you’re planning on replacing your existing sliding doors with a newer model. Newer sliding doors let you have larger panels so consider a two panel door for reduced aluminium sightlines and larger glass panels.

Our recommendation is the latest push-pull sliding doors, also called inline or the latest lift and slide models giving lighter operation and the option to lock the doors partially open. Sightlines on these start at 29mm. The ultra-slim models can also work well with mullion sightlines starting at 19mm

Take a look at the latest generation of thin-profile sliding doors, lift and slide or structurally bonded design, giving you the option for either fixing directly to the structure or recessed for a near-frameless appearance. There are even options for a fixed or open corner design.

With many new extensions, a more minimal look is popular, but new extensions look just as good using sliding doors with bolder flat profiles creating a distinctive picture frame effect, with or without slim mullions. Some two panel sliding doors comfortably go over six metres wide giving you a wall of glass.

It’s important to remember that many “slim” sliding doors are only slim at the middle mullion. Their frame dimensions at the sides and top are frequently the same if not thicker than regular sliding doors, unless you are hiding the doors in the structure on a new extension for a more minimal look, although this brings it’s own problems potentially.

Many showrooms also display their slim sliding doors with the hidden frame making doors look a lot slimmer than you’ll get. So don’t be taken just by the middle mullion. Check and compare the frame dimensions of the entire door set not just the middle. Or contact us for advice.

Inline and lift and slide doors are the best solution if you’re planning on using your patio doors for regular entry and exit or they are the only back door you have in the home. You’ll find these door types lighter and easier to use too compared with the very thin profile options.

These tend to be more functional than slimline or structurally bonded doors because they offer external locking and entry with better, more functional handles that are easier to grab and use day-to-day.

The mid-range brands offer an excellent solution for stylish, reliable and functional sliding doors for those on a budget.

Origin, Smart Systems Visoglide, Aluk sliding doors are some of the best doors at lower prices than the top-end brands but still come with excellent security, weather performance and colour options.

When your sliding doors are intended to create a wow-factor this assumes your doors are larger than most openings and you want to make the most of larger glass panels, the bare minimum of visible aluminium and minimal frame on show.

The best products are minimal sliding doors, the structurally bonded systems or those doors designed with the largest glass sizes and fewest sliding panels. Framed or frameless slide and turn doors are also an excellent solution. Doors with 20mm to 35mm mullions are also recommended.
