Aluminium sliding patio doors have become one of the most popular things we fit at Sheerwater Glass, and it’s easy to understand why. Slim frames and expansive glass panels flood your home with natural light, connect your living space to the garden and bring a clean, contemporary look that genuinely transforms a room.
The local experts at Sheerwater Glass have been supplying and installing doors and windows across Surrey since 1972, and we currently offer three aluminium sliding door ranges: the Cortizo, the Cortizo Cor Vision and the Sheerline. Each one has been chosen because it represents the best of what aluminium can do, whether you’re after ultra-slim corner glass, a classic smooth-sliding panel or a reliable British-made option at a more accessible price point.
Slim, versatile, and made to impress – Cor Vision aluminium sliding doors maximise glass, light, and style with a high-end finish tailored to your home.

The thing people notice first about our aluminium sliding doors is what’s not there. The frames are beautifully slender, which means more glass, more light, and a view of your garden that very little interrupts. Large glass areas aren’t just about looks either — they add real visual appeal and genuine value to your home.
The thing they notice second is how they feel to use. Panels that glide smoothly on stainless steel rollers, lift-and-slide options for larger configurations, and a door that opens with one hand and closes with a quiet, satisfying click. This is what finely crafted aluminium does that nothing else quite matches.
And if outside noise is something you live with, whether that’s road traffic, neighbours or a nearby flight path, certain configurations can reduce it by up to 39dB. You’d be surprised what a difference that makes on a warm evening with the doors closed.
Aluminium is incredibly strong for its weight, which is why the frames can be so slim. It doesn’t absorb moisture, won’t warp with the seasons, and handles whatever the Surrey weather throws at it without complaint. These doors are genuinely built to last.
Our aluminium sliding doors use thermal breaks inside the frame to stop heat escaping through the metal. Paired with double or triple glazing, they keep your home comfortable all year round and take the edge off your energy bills too.
Available in white gloss, anthracite grey matt or black matt as standard, or any RAL colour you like. Smooth or textured finish, single or dual colour, and we can match your existing frames too. There’s a good chance we can get it looking exactly how you pictured it.
To ensure your home doesn’t suddenly become an attractive prospect to potential intruders, we ensure all aluminium sliding doors have six key security features.
With Sheerwater Glass you will feel safe and secure in your home:
Aluminium sliding doors are one of the smartest ways to update your home. The large glass panels bring in more light, open up your living space and give you a clear, uninterrupted view of the garden. And because they slide rather than swing, they work just as well in tighter spaces. We offer two operating styles depending on your needs:
Both options are available across our three aluminium sliding door ranges, and our team will help you work out which suits your opening best.
You’ll speak to a real person, not a call centre. We’ll talk you through options, no pressure.

“It is no wonder that Sheerwater Glass are one of the oldest and most trusted companies in the Woking area.”
Our doors are fitted with polyamide thermal breaks and high-performance gaskets that keep draughts out and heat in. Add double or triple glazing and they can achieve U-values as low as 1.5 W/m²k, which is genuinely impressive for a door this size.
Yet by quite a lot. You can choose from a wide range of finishes in single or dual colour, select from various handles and accessories, and configure between 2 and 6 panels in either inline sliding or lift and slide. We can even recess the threshold into the floor level for easier access if that’s useful.
Panels are available up to 2600mm in height and we can install doors to fit very large apertures, so if you have a wide opening don’t let that put you off. The slim 42mm sightlines mean you get maximum glass and light regardless of size, and anti-lift blocks keep every panel securely on its track.
