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 is available as a sliding, pivoting, hinged or pocket sliding internal 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 available as an internal 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.
