Handiness is the main advantage of sliding glass system in comparison to other similar systems. The tempered glass used in this mechanism is 8mm thick. This mechanism is manual and by the movement of the first glass, other glass tiles move one after another. One another advantage of the sliding glass system is the maximum degree of opening. By use of 5-grooved rails you can open the window to 80 percent of its space easily. The width of the window span is divided to 5 parts which 4 of them can be retracted on the first part.
In order to achieve maximum airtightness and preventing dust entering inside, two brush strip are used in edges of every tile. The dimension limit in this system is up to 10 meter at width and up to 2.5 meter at height. Sliding window system is presented in two ways: internal sliding system and external sliding glass system. The only apparant difference between these two systems is in lower rails installed on the earth. In internal type the height of rail is 1cm but in external one it is 25cm.
