Trackless and Disappearing Glass Doors

Instead of the traditional design of glass sliding doors, the modern art of making glass doors offers a real miracle of technology - trackless and disappearing glass doors.

In fact, the traditional sliding door is a movable rectangular frame sheet of window glass, which is mounted parallel to the similar and usually fixed frame of the adjacent glass partition. This movable panel slides along a fixed track in a plane parallel to the adjacent fixed panel.

In the new design of trackless and disappearing glass doors, all glass panels are suspended from above, leaving the floor surface smooth and uninterrupted. When the doors are open, they "disappear" in the side pockets. With the final closure, they slightly lower, creating a weather-resistant seal. Such doors are recommended to be used mainly in a temperate climate.

To comply with codes for energy saving and noise reduction, sliding glass doors usually have double glazing and are often processed to reflect UV radiation.

Oar glass doors have better thermal insulation than trackless disappearing glass doors. However, glass in any form is not the best heat insulator, so most glass doors are recommended for use in temperate climates. For different climatic zones, appropriate types of glass, fasteners, and seals are selected.

To reduce the negative thermal impact on the living space, glass doors should have insulated frames and have double or triple glazing with low emission coating and gas filling (usually argon). Metal-framed glass doors should also have thermal breaks. Doors must be properly sized and protected from the sun. To do this, use curtains, blinds, and other means.
