Open-corner frameless sliding doors

A glass-to-glass corner.
A clear connection to your garden.

Open corner sliding doors from the Fineline collection

A DISTINCTIVE FINELINE DESIGN

No visible corner frame.
More room for the view.

FineLine sliding doors meet glass-to-glass at the corner. Closed, they give you a clear view without a visible corner frame. Slide both sides back and the corner opens to the garden, bringing the outside in.

British-made and designed around your home, the doors combine a slim 17mm interlock on the Infiniti FineLine system with smooth sliding operation. They suit a standalone opening, a contemporary glass box extension or a wider glazing scheme for your property.

We work with you and your architect to coordinate structural support, glass specification, tracks and thresholds. A free site survey and design consultation helps turn your ideas into a detailed quotation. We supply and install in London and across the UK, including Jersey and the Channel Islands.

DESIGNED FOR EVERYDAY LIVING

Fine lines.
Smooth movement.

17mm: The interlock between the glass panels is just 17mm wide, keeping sightlines slim and views open.
6–8 weeks: Typical delivery. We confirm the programme for your project when you order.

More light. Comfort throughout the seasons.

FineLine sliding doors offer a choice of high-performance double and triple glazing, including solar-control glass that helps reduce heat gain in sunny weather. Combined with thermal insulation to limit heat loss in colder months, the right glass specification helps create a comfortable living space throughout the year.

We tailor the glass to your home’s orientation, shading and how you use the room—balancing daylight, clear views and temperature control.

Low-iron glass offers a clearer appearance with less green tint. We can also discuss laminated glass options for your security requirements.

A considered connection to the garden

Smooth sliding operation makes large glazed openings practical for everyday use. Where the site allows, a level threshold can connect inside and outside floor finishes. We coordinate the track, drainage and surrounding construction before installation.

THE FINELINE DIFFERENCE

Designed around the view.

More glass. Less visible frame.

FineLine sliding doors use the strength of the glass to minimise visible framing, creating expansive views and bringing more daylight into your home. The surrounding frame can be largely concealed within the walls, with the track recessed into the floor for a clean, integrated finish.

Large doors that glide smoothly.

Precision stainless-steel rollers help large glass panels move smoothly and easily. A choice of handles, threshold details and track covers allows the system to be tailored to your home, combining a minimal appearance with practical everyday use. Thresholds and drainage are coordinated with the surrounding construction.

Open the corner. Connect to the garden.

Combine sliding and fixed panels to create an opening that suits your space. FineLine’s glass-to-glass corner design opens without a fixed corner post, creating a clear connection between your home and garden. Where the building layout allows, panels can slide into a wall pocket, disappearing from view when fully open.

THE DETAIL MATTERS

Planning your
sliding doors.

What are open corner sliding doors?

FineLine doors meet glass-to-glass with no visible corner frame when closed. Sliding both sides back creates a clear corner opening and access to the patio. The layout and structural support need to be considered with your architect during the design stage.

What is the difference between frameless and slimline sliding doors?

These terms describe the minimal appearance of the glazing, but they do not always mean the same construction. Compare the visible sightline where panels meet, the perimeter frame and the threshold detail. Ask which parts of the frame remain visible in your proposed installation.

How much do frameless sliding doors cost?

A bespoke quotation depends on opening dimensions, the number of panels, glass specification, corner configuration, finishes and installation access. Send your drawings, approximate measurements and project postcode so we can discuss a quotation for your project.

Can sliding patio doors have a level threshold?

Discuss finished floor levels, track depth, drainage and weather exposure early. The appropriate threshold detail depends on the system and the site; confirm it before floors and patio levels are set.

What glazing should I choose for a south-facing room?

Orientation, shading and room use affect the choice of glass. Discuss solar control, thermal performance and daylight together. Performance values need to relate to the complete specified door system, not just the glass.

Do you supply and install in London and Bristol?

Yes. Fineline supplies and fits frameless sliding doors across the UK, including London, Jersey and the Channel Islands. Call our London number, 020 3824 0845, or our Bristol number, 0117 235 3936, and share your project postcode.

How long does delivery take?

Typical delivery is 6–8 weeks. We confirm the programme for your particular door configuration, glass specification and installation when you order.

Can you work with my architect?

Bring your architect's drawings to the initial discussion. We can review opening sizes, corner layouts and junctions with the surrounding building as part of the survey and design process.
