Granular foam glass    PDF Tisk Email
Foam glass is the only thermal insulation material that is resistant to both chemical and physical influences.The material consists of coal and glass glass. After special heat treatment, the mass acquires a characteristic porous structure consisting of closed cells.Foam glass has retained the basic properties of glass, but at the same time it is an absolutely incompressible material with low thermal conductivity.Foam glass can neither get wet nor moldy, it does not serve as a habitat for rodents.But more importantly, the material is fireproof and does not lose its properties over time.When exposed to high temperatures, there are no harmful emissions, no changes in the shape of the insulation, and no spreading of smoldering fires. The spread of fire in rooms insulated with this material is impossible.It is practically an eternal insulation material. If expanded polystyrene, mineral wool, expanded clay and other types of thermal insulation materials lose their qualities over time under the influence of variable humidity, vibration, freezing cycles, and ultraviolet radiation, then foam glass is not susceptible to such effects.Foam glass is not only an excellent heat insulator, but also a waterproofing agent. With proper mastic treatment of the seams, the insulation reliably protects the insulated surface from moisture penetration.The insulation is quite light, when mounted on internal walls, it is enough to use bitumen or mastic. When processing the outer perimeter, dowels should be used in combination with adhesives to install thermal insulation. At the same time, one dowel is enough for each insulation block. The most effective insulation is in two layers, and the second layer is laid so as to overlap the seams of the first (in a checkerboard pattern). There is no need to strengthen the second layer with dowels.Porous foam glass blocks are quite easy to process and, if desired, you can give the surface a non-standard shape (sphere, cylinder).It is important to note that the coefficient of thermal expansion of foam glass is almost the same as that of steel and concrete. Therefore, as a result of temperature fluctuations, cracks do not appear at the points of contact of materials and the integrity of the structure is not violated.The rough surface of the blocks contributes to excellent adhesion with plaster compositions, using reinforcing mesh.Foam glass is implemented in blocks, but granular foam glass is often used.Granules are used as a loose insulation or as a filler for warm plasters, light concretes and mortars.A solution with the addition of granular foam glass minimizes the formation of cold bridges when laying foam concrete blocks, since the thermal conductivity of such a solution is much lower.The pellets are produced in four sizes: 1) up to 5mm; 2) from 5 to 10mm; 3) from 10 to 20mm; 4) from 20 to 40mm.In addition, granular foam glass is classified according to density (150, 250 and 350 kg/m3). The higher the density of the granules, the higher the thermal conductivity, which varies from 0.06 to 0.1W/m°With.It is packed, like other bulk insulation, in bags or soft containers.
