Types & Manufacturers Frameless Glass Internal Sliding Doors

Jump to: Styles, Construction Materials, Manufacturers

Frameless internal glass sliding doors are among the hottest design elements in Europe today. Building with glass gives architects and designers the ability to be flexible with internal spaces without sacrificing beauty and modern design elements. Internal glass doors can be combined with glass partitioning systems to create entire rooms that are private and distinct yet with a look and feel that is welcoming and wide-open.

In the following paragraphs, you will find information about different types of frameless internal glass sliding doors, the materials these are made from, and some of the most well known manufacturers offering these in the UK. We hope you find this information useful for your own residential or commercial design projects.

Different Door Styles

There are three primary door styles for use in internal applications where sliding doors are preferred. Sliding doors might be used for office space applications, main entrances, conference rooms, and such. The three styles are:

Pocket Doors

The typical pocket door design can be adapted to make use of frameless glass doors. This design provides a rail on which the doors hang, and pockets into which they slide. This option is often used when a sliding glass door is desirable for space with otherwise solid walls.

In-Line Doors

The in-line door is similar to the pocket door with one major exception: it hangs on an external rail that keeps the door outside of the wall. In other words, the open door is not recessed into a pocket where it is hidden from view.

Telescoping Doors

Telescoping frameless internal glass sliding doors are very popular in commercial and industrial environments right now. A telescoping design allows for up to four glass panels mounted on a succession of tracks to move out of the way in succession. A fully retracted door can provide an opening as wide as 16 feet. Equally important is the aesthetic appeal that can easily make the difference when trying to impress business clients.

Construction Materials

Frameless glass doors must be made to exact specifications in order to provide stability and durability. These must also be installed according to manufacturer instructions, down to the very last detail. Materials used for these highly desirable doors are as follows:

Tempered Glass

All frameless glass doors must be made with tempered glass in order to be strong enough to hold up without framing. Tempered glass is highly resistant to shattering as well. In the case of breakage, a thin laminate prevents the door from breaking into millions of little pieces.

Electric' Glass

For applications requiring privacy without the use of external blinds, and electrified glass product can be used. When no electric current is applied, the glass is completely opaque; it becomes clear when electrical current is run through it.

Frosted & Etched Glass

Some designers looking for a special presentation may take advantage of frosted or etched glass. Both types of glass can be tempered and laminated for safety and durability.


In the world of glass, the word 'glazing' can apply to a single sheet or pain of glass, or to a process applied to the glass by a skilled glazier. Where these processes are concerned, there are a number of options including fire rated glazing, acoustic glazing, solar thermal glazing, and insulated glazing. Each of these processes is applied to glass to meet a specific customer need.


Aluminium is one of the more popular choices for both sliding door tracks and hardware. Aluminium is lightweight, durable, inexpensive, and easy to recycle. It can also be finished in a number of different options to add beauty to any installation.

Stainless Steel

Applications that are especially heavyweight may require stainless steel tracks or rails rather than aluminium. Some people choose stainless steel not because of weight concerns, but because they prefer the industrial look it provides. Stainless steel is extremely strong as well.


Although brass is too soft to be used for rails and tracks, it is used for wheel mechanisms and fixtures. A polished brass door handle, for example, adds an element of timeless beauty for glass applications in a more refined setting.

The most reputable manufacturers of frameless internal glass sliding doors offer the full range of styles and materials listed above. As you might expect, there is no shortage of quality manufacturers given the popularity of these products on today's market. Many of the best manufacturers are located in Europe and the United States; below is a list of some of the biggest names in the business.

Manufacturers & Brands of Frameless Internal Sliding Doors

Eclisse was 'born' in 1989 in a factory located in northern Italy. The business was originally founded on new technology designed to eliminate the problems associated with sliding glass doors.
