Insulation - is one of the most important components in the construction of industrial, residential and business-fabricated buildings. It protects the interior walls of the penetration of cold and moisture, as well as soundproof walls. Exterior walls protected from exposure to rain and adverse weather events (high and low temperatures, wind).
In the construction industry used many kinds of heaters with different characteristics. This may be the special plates, прошивные mats on the basis of mineral fillers, glass fiber and wool, materials based on foamed polystyrene.
Basalt insulation
Heater on the basis of basalt rocks - a material having a fibrous structure, the fibers are intertwined in a chaotic manner, creating a dense and sufficiently hard layer. This environmentally friendly material that has fire resistance, water absorption, durability. Available in the form of fibers, прошивных mats and slabs of varying degrees of stiffness. Used in construction and roofing as the primary insulation layer. The material has a valuable asset - promotes proliferation and attenuation of fire, so often used as a protective fire-fighting and fencing.
Wind slab – This material is intended for external insulation of facades and exterior walls. At the same time, the material provides heat and sound insulation of sandwich panels.
Plates are easy to mount (Scandinavian plates are fastened directly to the wall, a crate is not required).
Wind slabs are lightweight materials - plate size 2700h1200h12 weighs no more than 9 kg, wide temperature range of application of material from - 250 to + 850 degrees allows the use of plates in different climatic zones.
Heater on the basis of polystyrene
Polystyrene foam - a lightweight, resistant to climatic influences material not affected by spoilage and rotting. Do not enter into chemical reactions with the most famous and common compounds, except for organic solvents, alcohol and gasoline, destroying the structural basis of the material. Protecting structures from sandwich panels item assembly are a cellular structure, not allowing the fire to spread within the panels. Therefore, the wall panels is justified by the use of polystyrene foam.
Not influenced by temperature difference (the material should not be stored in direct sunlight), high Humidity.
With the honeycomb structure increases the insulating properties of the material. Easily transportable, has a light weight, non-toxic. It has the lowest thermal conductivity of all known insulating material.
