uPVC sliding doors are now almost as common as uPVC window frames, and it's easy to see why. A uPVC sliding door needs little upkeep, insulates well and can be made to fit almost any opening. Here's what to know before you buy one, including what to check when choosing an installer.
What is a sliding patio door?
A sliding patio door links your living space to the garden. It's mostly glass, so it brings in a lot of light, and because the panel slides rather than swings, it takes up no floor space. Sliding doors come in aluminium, timber and uPVC; uPVC is usually the most affordable of the three and the easiest to look after.
A uPVC sliding door is low-maintenance
uPVC doesn't need painting or sanding. Wiping the frames down a few times a year and keeping the bottom track free of grit is usually enough. Spray the runners and locks with a silicone lubricant once a year so the door keeps sliding smoothly. A well-made, well-fitted door lasts many years, which is the same reason so many people choose uPVC window frames.
Made to measure
uPVC sliding doors are made to measure, so you choose the size, the colour or wood-effect finish, and which panel slides. Think about how you'll use the door: which side you walk through most, where furniture will stand, and whether you want a low threshold for easy access or a pram.
Better insulation and energy use
A good uPVC sliding door with modern double or triple glazing keeps heat in far better than an old single-glazed door. That means fewer draughts, lower heating costs and a better energy rating. Ask about the door's insulation value and the glazing specification when you compare quotes. uPVC can also be recycled at the end of its life.

uPVC sliding doors & quality certification
Every brochure looks good. To judge quality, check whether the supplier is certified under a recognised scheme for window and door installation. These schemes check the product and the fitting, and often include an insurance-backed guarantee that protects you if the company stops trading. Also ask about multi-point locks and security-tested hardware, and read recent reviews.
