Back in the 30s of XX century Soviet academician I. Kitaygorodsky created a new material based on the special properties of silicate glasses - at temperatures of about 1000 ° C in the presence of a blowing agent, they soften and foam.The cooled molten glass is very durable and resistant to mechanical stress.

Scientists developing this material is to be used mainly by its buoyancy, but it turned out that the foam glass has excellent thermal insulation and soundproofing properties.The use of this material as a heat insulator began in the 40s in Canada, and is widespread in Europe and America.In the USSR, foam glass is not as widely used as its production is not developed, the material had a high cost.

In recent years, the production of foamed glass started to develop rapidly, because this material has unique properties and performance characteristics superior to other insulating materials.First of all, foam glass - a material absolutely harmless, does not emit harmful substances, even when exposed t

o high temperatures.Resistance to temperature is very high, foam glass does not burn, and can withstand heat up to 600 ° C.Foam glass is not subject to degradation over the lifetime, it does not crumble, it is not saturated with moisture and does not corrode.

Foam glass - completely inorganic material, so using it in building a country cottage, there is no fear that it will destroy rats, insects or microorganisms.With its high strength, this material responds well to machining, it can be given any shape.Installation of foam glass also is not a problem, it can be attached by any modern mortars.Because the foam glass - lightweight material, the weight of the building and, consequently, the pressure on the foundation is reduced, and the construction becomes more economical.

High compressive strength inherent foam glass also helps reduce the cost of and accelerate the construction, since it allows to refuse the installation of reinforced screed floors, reduce unloading zone in the regeneration of facades and others.

Foam glass is produced in the form of blocks, pellets andrubble, the scope of these types of foam glass is slightly different.The blocks can be used as thermal insulation in the construction of walls, roofs, basements, as well as piping arrangement.Blocks of foam glass are excellent protection for granaries and can act as ognepregraditelnyh designs.The pellets are used as insulation Sediment and filler for lightweight concrete.Rubble can be used as well as pellets of foam glass and regeneration of roads.

as raw material for the production of foamed glass is used such rocks as trachyte, syenite, nepheline, obsidian, volcanic tuff, as well as the waste of conventional glass, ie, glass, resulting in the production of sheet, container, electrical windows,crystal products.


Technology development and application of innovative solutions possible to develop a process for the manufacture of foamed glass cullet without expensive, and therefore excluded from the process of its milling operations.The new technology involves the use of inexpensive raw materials - such siliceous rocks as diatomite, flask, tripoli, zeolite.A feature of these species is that unlike river sand, they contain silica in an amorphous rather than crystalline form.

materials produced by new technologies, are called "penosteklokeramika" they retain all the performance characteristics inherent in the foam glass, but can be used not only as insulation, but also as a structural-insulating materials.Penosteklokeramika does not require additional protection from moisture, such as cellular concrete, can reduce the number of structural layers, simplify wall construction.

thickness of the wall erected from penosteklokeramicheskih blocks, 6 - 12 cm less than the thickness of the wall of the traditionally used materials.Manufacturing technology penosteklokeramiki allows the use of pigments, so you can get the building blocks of different colors that do not require plastering and painting.

Obviously the use of blocks of penosteklokeramiki significantly reduces construction.The wall of this material cost almost twice cheaper than a wall of foam, followed by lining.The savings achieved and by reducing the cost of insulation and finishing materials, and at the expense of cheaper foundation, because the weight of the walls of penosteklokeramiki about 10 times less than the weight of a brick wall.
