Frequently Asked Questions

What are Frameless Single Glazed Sliding Doors?

They are systems where glass panels slide along a track with minimal or no visible surrounding frame, and the glass is a single pane (not double glazed). The glass itself is often the main structural component.

Are the doors truly "frameless"?

No system is 100% frameless. They use top and bottom tracks and depending on the application very slim vertical profiles, giving a maximally glazed, frameless aesthetic.

What is "Single Glazed"?

It means the system uses only one pane of glass per pane, as opposed to double glazing, which uses two panes separated by a gas-filled cavity.

Where are these doors typically used?

They are ideal for internal room dividers, office partitions, and patio enclosures or sunrooms.

How is the glass secured without a frame?

The glass is structurally bonded to very minimal aluminum profiles at the top and bottom.

How thick is the glass?

The glass is toughened safety glass and is usually between 8mm and 12mm thick, depending on the panel size and application.

Are they safe?

Yes, they use safety glass (which, upon breakage, shatters into small, less harmful pieces.

What are the aesthetic benefits?

They offer an uninterrupted, expansive view, maximum light ingress, and a very modern, minimalist, ‘all-glass’ appearance.

How do they compare to framed doors on light?

They allow for maximum natural light because there are no bulky frames or large vertical mullions to obstruct the view.

Do they provide good thermal insulation?

They offer similar thermal performance to traditional sliding/hinged windows and doors.

Can they be used as external patio doors?

They work well for external patio doors creating great flow and easy access.

Do they offer good sound insulation (acoustic performance)?

Acoustic performance is limited with single glazing compared to double glazing. They offer some sound dampening but are not high-performance acoustic barriers.

How do the panels operate?

They run on a bottom track and wheel system.

Can the tracks be recessed into the floor?

Yes, a key design feature is often a fully recessed floor track to achieve a seamless, low-profile, barrier-free transition.

What locking options are available?

Locking mechanisms can vary, but often include simple patch locks, floor bolts, or integrated multi-point locks on the meeting stiles for security.

Can I have a handle on the glass?

Yes, handles are typically discreet stainless steel pull handles, glass-mounted patch handles, or small recessed finger pulls.

Can the glass be customized?

Yes, glass can be clear, frosted (for privacy), tinted, or customized with etched patterns.

How do you clean and maintain them?

Maintenance is generally straightforward: regular cleaning of the glass with standard glass cleaner and keeping the bottom track clear of debris for smooth operation.

Are they prone to condensation?

Yes, but no more than traditional framed sliding doors.

Can they be motorized?

No.

What is the maximum panel size?

Maximum size varies by manufacturer, but a single glazed panel can be quite large, often exceeding 3 meters in height, leveraging the glass’s strength.

Do I need a fixed panel?

No, systems allow all panels to slide and stack, creating a full opening.

How is privacy managed?

Privacy can be managed using frosted, etched, or switchable smart glass, or by adding curtains or blinds externally.

Do they seal tightly against wind and rain?

While internal versions don’t need weather sealing, external-rated frameless systems do include seals (brushes, gaskets) but typically have a lower weather rating than high-performance framed double-glazed doors.

Are they more expensive than framed doors?

Generally, yes. The complex engineering, high-quality hardware, and specialist installation required to create the ‘frameless’ effect often result in a higher cost.
