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.
