uPVC patio sliding doors: installation, benefits and design tips

uPVC patio sliding doors are one of the simplest ways to connect your home to the garden. Large glass panels slide back with smooth operation rather than swinging open, so you gain more floor space, opening up your living space, while the wide panes of glass bring in far more natural light than a standard door. They also need very little maintenance, which makes them a natural fit for busy kitchens, extensions and garden rooms.

At Malbern Windows, our own experienced team surveys and installs every sliding patio door, so you’re never dealing with a subcontractor. It’s an approach that’s served homeowners across the North West for more than 40 years.

What makes sliding patio doors so popular?

From the moment they’re fitted, uPVC sliding doors show their advantages in many ways:

• Natural light – large panes of glass and slim frames let daylight flood into the room, without the swing clearance a hinged door needs
• Thermal efficiency – double or triple glazing with tight seals cuts heat loss, so rooms stay warmer for less and draughts around the frame are a thing of the past
• Security features – multi-point locking and toughened safety glass come as standard on every door we fit
• Low maintenance – minimal upkeep is needed, just a wipe with a damp cloth, with no repainting or sanding required

Sliding doors compared with French doors

We also fit uPVC French doors, which have real benefits of their own depending on your home and lifestyle, here’s how the two styles compare:

So which is right for your home? It often comes down to the style of your home: sliding doors are the ideal choice where floor space is tight or small spaces need opening up, while French doors suit traditional homes with more period character, where the classic look matters more than an open floor plan.

Sizes, glazing and colours

Once you’ve settled on a style, there are still a few practical decisions to make before your door is measured up:

• Size – made to measure, so your door fits the exact opening rather than the nearest standard size
• Glazing – double glazing suits most UK homes, with the gap between the panes filled with argon gas to help trap heat and cut down on outside noise; triple glazing is worth considering on noisy roads or exposed locations, where tight seals matter more
• Threshold – a low or level threshold makes for easy access onto the patio or garden, worth thinking about if you have young children, a pushchair or reduced mobility to consider
• Colour – a wide range of colour options, including white, black, rosewood, golden oak and anthracite grey, plus a colour-matching service if you want an exact shade to fit in with the rest of your home

Every home is different, so our team is happy to talk you through the options for your sliding patio door before you order, since price depends on size, panel count, glazing spec, frame colour and threshold.

What happens during installation?

In most cases a standard sliding patio door installation is completed in a single day, with our team handling everything from the initial survey through to the final clean-up and minimal disruption to your home.

Fitting the door correctly matters just as much as choosing the right one. A poorly aligned bottom track can affect the sliding mechanism and how smoothly the door runs for years to come, which is why every sliding patio door is surveyed and installed by our own experienced team rather than a subcontractor. We’re a family-run business, so your home gets the same care and attention we’d give our own.

Discuss your patio door project

Every door we fit comes with multi-point locking, toughened safety glass and a 10-year insurance-backed guarantee, so you can order with peace of mind. If your current doors are draughty, ageing or hard to lock, a made-to-measure uPVC sliding door is an ideal solution for more natural light without losing floor space.
