Sandwich panels in Uzbekistan

Sandwich panels are a modern building material, which is a multilayer structure consisting, as a rule, of two metal sheets and a layer of insulation between them. The combination of metal strength and thermal insulation properties of the filler makes sandwich panels indispensable in many areas of construction.

Thanks to the simplified installation process of sandwich panels, construction becomes fast and economically profitable, which further enhances their attractiveness in the construction materials market.

Sandwich panels: types, classification and properties

Sandwich panels are a three-layer structure (sometimes two-layer), consisting of:

• The core – thermal insulation material
• Metal sheets (on both sides) – which serve as a covering. Sometimes metal is replaced by other materials. It is between them that the core is located.

Application exterior decoration (residential, industrial, commercial areas).
The direction of the facade and cladding.
The purpose for which the panels are used is insulation.

The types of products differ in the following parameters:

• Purpose;
• Filling;
• The coating used;
• Technical data;

This allows you to choose the most practical for modern decoration of any building.

Classification

By appointment

• Sandwich wall panels are used for cladding facades and the construction of internal partitions in garages, sheds and hangars, suitable for vertical and horizontal installation.
• Roofing sandwich panels are used for pitched roofs on frames made of wood or metal, they are not used on flat surfaces.
• Acoustic panels with perforations and special materials in the joints reduce noise by up to 95% and are designed for sound insulation near busy roads and highways.

Distinctive features of each species:

• Wave height;
• Insulation thickness;
• The keyhole connection included in the design;

The service life is the same. It is 35-45 years old.

By thermal insulation material

The filler is:

1. Mineral wool (mineral wool), including basalt wool: A refractory thermal insulator with a fibrous structure made of silicate and basalt melts. It requires hydro protection due to hygroscopicity up to 2%. It is used with stainless steel protection to prevent corrosion and provide sound insulation. Basalt wool, as a subclass of mineral wool, is especially appreciated for its high thermal and sound insulation, as well as fire resistance. Both varieties are environmentally friendly and are not susceptible to shrinkage.
2. Polyurethane foam (PU foam): Easily workable material with closed pores, providing waterproofing. It is flammable, but resistant to physical damage and thermal deformation. It does not require special supports during installation, adheres well.
3. Polyisocyanurate foam: An improved version of PU foam with high fire resistance. The composition includes polyol and isocyanurate bonded by polymerization, which forms a carbon matrix. It does not decrease in volume, is resistant to aggressive environments, but is sensitive to UV radiation.
4. Fiberglass (glass wool): Elastic mineral thermal insulator with good durability due to the length and thickness of the fibers. Resistant to weather conditions, does not require significant efforts during installation. It is hygroscopic, requires protection from wind and can cause skin irritation.
5. Styrofoam: High thermal insulation properties, resistance to biological and chemical influences. Metal layers protect from sunlight. Highly flammable, requires caution when used near fire sources. It isolates sounds well, retains properties in contact with water.
6. Combined heat insulator: It combines expanded polystyrene and mineral wool, providing strength and high thermal insulation properties. Fire resistance due to cotton wool. It is bonded with polyurethane glue, the choice depends on the purpose and operating conditions of the building.

By type of polymer coating

The products are treated with a coating. It protects against the negative effects of the environment.

• Polyester (PE): The thickness of 25 microns provides protection in any climate, without deformations up to 120 degrees. Available in matte and glossy versions.
• Polydifluoride (PDVF): It can withstand temperatures from -60 to +120 degrees, is resistant to chemicals and corrosion.
• Pural: Based on polyurethane, it creates a unique pattern, is resistant to alkalis and rust, and is suitable for internal and external use.
• Plastisol: It is made of PVC, the thickness varies, it is resistant to cracks and deformation.
