Sandwich Panels

Sandwich panels – a modern construction material, without which it is impossible to imagine both civilian and industrial construction. It's lightweight design, easy to install and incomparable to any material in their heat and sound insulation properties (100 millimitrovaya panel with mineral wool insulation on its thermal insulation properties of 7 times the brick wall of the same thickness). The main purpose of the sandwich panels – Protecting designs in the construction of prefabricated buildings. Sandwich panels are of the following types: wall, roof, ceiling (used in decoration) partitions, including fire; facing (used in the reconstruction and insulation of old buildings) panels for cold rooms. The application of sandwich panels: industrial buildings, warehouses, service centers, shopping malls, sports facilities, medical complexes, including "Clean rooms", the building-"fridges"; agricultural buildings, reconstruction of buildings and structures.

The design of multi-layer sandwich panels, as follows from name. The most common type – frame consisting of two shaped steel sheets, filled with insulation. The use of profiled steel sheet attached to the panel rigidity. As a rule, ends represent a kind of "lock" that makes it easy to mount, and in some designs to avoid the so-called "cold bridges". The most common insulation sandwich panel mineral wool, polystyrene, polyurethane foam. Mineral wool – a natural material made of silica rock melts the synthetic resin binder, and polystyrene foam – plastics. Heaters fairly waterproof, but the mineral wool as the absorbent material, yet is able to absorb moisture, which greatly reduces its thermal and sound insulation properties. To reduce this gap by manufacture of sandwich panels used vapor sealing materials.

Sandwich panels with polystyrene insulation from completely moisture resistant. The thickness of sandwich panels ranged from 50 to 300 mm, depending on the application and region-building. Weight sandwich panels as thick as 100 mm of polystyrene insulation with 1.5 easier panels with mineral wool insulation. This figure makes polystyrene foam insulation panels with a more attractive when construction, as reduced transportation costs and the load on the foundation of the building. The difference of heat-insulating properties of different insulation is low, it varies between 15% and EPS retains heat better. The level of fire resistance is higher in the mineral wool: under high temperatures, it can break down, but does not support combustion. Perhaps, therefore, a sandwich panel with insulation that are most common in Russia.
