Insulating material from fenopolyazocyanurata: Features

The design feature of the metal three -layer sandwich panels is that the structure of this building material is multi -layered, unlike others. The outer and outer layer of the sheathing is a steel sheet, which on both sides performs the function of the lining of the sandwich panel. All three layers are reliably glued together with a two -component polyurethane composition of polyol and isocyanate.

In the process of production, in automatic mode on the front and internal sheet of the panel cladding, various types of profiling is applied. Today, the buyer offers roofing and wall sandwich panels (mineral wool, fenopolyazocyanurate, polystyrene foam, polyurethane foam) with a V-shaped depression, wave-like surface (micro profiling), a smooth surface, alternating trapezoid and textured image in the form of a variety of ornaments and patterns. Sandwich panels color solutions are selected in accordance with the classification of RAL.

Depending on the type of coating, the technical characteristics differ. The most popular and common types of coating are: polyester, purl (based on polyurethane), and PVDF. To protect the polymer coating during transportation or during installation, the sandwich panels are covered with a protective film in production. Before installation, it must be removed from the locking joints. From the panels themselves, the film must be removed immediately after installation or no later than three months from the date of manufacture of products.

The insulation material is selected depending on the functional purpose and the use of sandwich panels. The heat -insulating core of mineral wool is distinguished by good chemical resistance, excellent – heat, – soundproofing characteristics and fire resistance. The sandwich panels from mineral wool belong to the class of non -combustible materials and meet the requirements of fire safety.

Isolation material made of fenopolyazocyanurate has one of the lowest thermal conductivity coefficients, it is chemically neutral to alkaline and acidic media, can also work in the ground and serve as an anticoro for metal. The distinctive feature of the fenopolyzocyanurate is that it is not subject to decomposition and decay, is not destroyed under the influence of temperature fluctuations, an aggressive industrial atmosphere, and.
