A leaf finishing material has appeared in the building materials market for quite recently, called the glass -deck sheet. Outwardly, such a sheet is difficult to distinguish from drywall, but internally they differ significantly. Due to the differences in operational characteristics, the price of SML is slightly higher than the cost of a similar sheet of drywall. And this is not surprising, because the drywall sheet is just a dense layer of gypsum wrapped in cardboard. In turn, the SML plate consists of several layers of natural materials that are reinforced with fiberglass fabric and wrapped in thick facing paper. Thus, it turns out that drywall is best used for internal finishing work, but the use of the SME covers areas that sheet materials have not “dreamed”. The stability of this material to the effects of water, fire and temperature changes allow it to be used not only for internal, but also for external work. Thanks to the unique properties of magnesite, which is the basis of the sheet, SML is used both in low -rise and industrial construction. They are actively used during the construction of frame houses instead of fiberboard or OSB plates, which significantly reduces the cost of the construction. The buildings in the construction of which were used by a glass -frost leaf, are environmentally friendly, strong in front of mechanical damage, immune to moisture and fire. Working with glass -frog leaves is as easy as with drywall. Sheets of SML, the installation of which is carried out without the use of specialized equipment, can be used not only for walls of walls, but also to create light and strong partitions between rooms, suspended ceilings, grounds for flooring and roofing, indifferent formwork. What else can be said about the glass -frog leaf? The characteristic that is not paid much to attention is the environmental friendliness of the materials used, which does not allow to accumulate in the house of additional dust and prevents chronic diseases. This requirement in developed countries is put forward to all buildings, where a long stay of people is supposed. Therefore, it is not rarely firefighters in restaurants, hotels, cafes and bars are sheathed with glass -frogs to increase fire safety.
