ADL Internal sliding glass doors Range

Internal Sliding Glass Doors

IQ Glass can offer a range of slim framed aluminium internal sliding glass doors. The Line range is one of four from IQ, and although it is only available as a sliding glass door there are many design options available.

The Line internal glass door is ideal for creating a separation between two interior spaces within the home, such as a living space and a home office.

The aluminium framing used for these doors is very slim, combined with glazing that allows the doors to almost disappear when open, maximising the space within the areas. The ADL door range as a whole creates a high-tech and innovative style door.

The aluminium framing used for these Line sliding glass doors allows them to be lightweight, meaning they can easily be opened or closed as well as being sturdy and long-lasting.

Design Options and Integrated Lines

The ADL Line range is available with a number of different glass finishes including clear, frosted, bronze and reflective. By integrating frosted glass into the design, you are able to create a new space that has additional privacy whilst allowing the natural light to pass between the two spaces.

The Line door is only available as a sliding glass door with integrated horizontal aluminium bars which are applied to the face of the glass, creating a line effect for a contemporary design. A crosshatched design can also be integrated to create a Mondrian style design, to match with your luxurious Mondrian external windows and doors.

Frame Design

The Line internal doors are made using an extruded aluminium frame. The standard design of the internal door frame is as pictured with multiple horizontal transoms that are more concentrated at the centre of the door. This framed design creates a unique appearance to the internal sliding doors as well as assuring an element of privacy through the glazed internal screens.

Alternative transom designs are possible on request.

The aluminium frames of the Line sliding door system are available in a range of colours and finishes to suit a wide range of project requirements. These colours include natural aluminium, white, light grey, iron grey, brown black and light bronze as standard. The frames can also be lacquered in any RAL colour on request.

The Line internal doors can also be finished with wood veneer to create a natural wooden frame finish for interiors. The specialist timber veneer can be either: Light European Oak, Caneletto Walnut or Smoked European Oak.

Door Configurations

The Line internal door is available as a sliding door (with the option of a pocket door), a hinged door and a pivot door. The internal sliding door is available with a 1,2,3 or 4 track system with a variety of sliding configurations. The sliding doors can be installed with an antiskid device for a soft open and close mechanism. Bi-parting sliding doors are also an option, these are an extremely popular choice.

Each sliding door installation can be up to 3.2m tall. The sliding panes themselves can be between 500mm wide and 1500mm wide. The beauty of the sliding doors is that they are top hung which means that no base frame or floor track is needed - resulting in a completely seamless transition between rooms. The head of the sliding door track can be fixed to the ceiling, to the wall or hidden within the ceiling finishes.

The ADL Hinged Line internal door is a beautiful addition to modern homes, the design detail of this system provides a contemporary finish that enhances internal doorways. The hinged door can be manufactured to a height of just over 3m tall to create a real statement to interiors. As with the other ADL Line configurations, the hinged door can be manufactured in a wide variety of frame and glass finishes to create the desired aesthetic.

Similar to the ADL Line Hinged door, the ADL Line Pivot door creates a unique addition to modern interiors. The pivot door can be manufactured to large sizes to create a statement feature. The pivot motion is created by a two-point pivot system located to one side of the door - the pivoting point will vary depending on the size and weight of the specific door.


At the Showroom

There is a four pane Line sliding door on display at the Sky House Design Centre in Amersham. The two-track internal sliding door bi-parts in the centre and is used as a part of a bedroom lifestyle show space.

The frame on show is light bronze and the glass is smoked for a slightly obscured vision through the glazed screen.

In addition, we have all the glass finishes and frame colours available to inspect via hand samples and other ADL internal doors that are installed throughout the IQ Glass showroom and wider Sky House Design Centre.
