Types and advantages of composite panels

Composite board is a new type of thermal insulation material, which is increasingly used in our daily life. Composite panels are usually divided into the following categories.

Polyurethane (PUR)

Polyurethane is a rigid foam made by mixing the main components “polyol and isocyanate” with catalyst materials under high pressure and special production conditions.

Polyurethane has a closed cell structure, which ensures excellent thermal insulation, high dimensional stability, and does not absorb water. It does not produce bacteria. Due to its high compressive strength, its mechanical properties are very high.

Polyisocyanurate (PIR)

When the main components of polyurethane foam undergo chemical reactions in different mixing amounts, a new macromolecular structure is formed, called polyisocyanurate. Polyisocyanurate rigid foam is a type of polyurethane, which has higher fire resistance due to its different structure. Compared with polyurethane, there is very little smoke formation in the event of a fire.

Mineral wool

Mineral wool is a general term for fibers obtained by melting inorganic rocks and other inorganic oxides at high temperatures. With its fibrous and open-cell structure, mineral wool is an ideal choice for your construction in terms of sound insulation and fire resistance. When conducting thermal insulation, it has a lower insulation value than PUR and PIR.

The mineral wool in the sandwich board is cut into thin slices in our fully automatic production equipment, and its fibers are used in a position perpendicular to the surface of the board. Therefore, the pressure resistance of the panel increases, and its mechanical value increases.

You may prefer to use mineral wool insulation materials, especially for buildings that require high sound insulation or for buildings with fire hazards, or for any building that stores flammable/explosive materials.

Expanded polystyrene (EPS)

Expanded polystyrene is a thermoplastic material and a derivative of petroleum. First, the polystyrene raw material with a fine particle structure is heated and expanded with water vapor. Pentane gas is an organic component used to expand particles. After the inflation process, the polystyrene particles adhere firmly to each other and assume the shape of the mold they are in. Finally, after shaping it into a block, expanded polystyrene can be used by cutting it into thin slices.

At the end of this process, pentane gas replaced air. This static dry air is trapped in fine particles with small holes, so that the EPS board can provide excellent thermal insulation for the building.

EPS is the most economical and lightest product among all types of insulation materials.

Advantages of sandwich panels

Quick and easy installation

Contrary to the traditional system, the continuous production of sandwich panels is fully compatible, and assembly parts can be prepared according to the required size, insulation type and color according to the structure of your facility, and the engineering and quality control process can be carried out in the factory in advance.

The installation of the splint is very easy because there are few seams on the wide surface. Through advanced transportation opportunities and mechanical lifting equipment, the time for handling and cladding is greatly reduced. Therefore, your project is delivered in a short time, which saves time.

Perfect insulation

Insulation means reducing the energy used for warming in winter and cooling in summer; and measures are taken to prevent heat transmission, with the goal of living in a comfortable environment. Sandwich panel is a building material, very suitable for thermal insulation.

Sandwich panels provide high thermal insulation through PUR, PIR, EPS and mineral wool insulation materials. The insulation layer with sandwich panels prevents mildew and humidity caused by heat movement and condensation, and ensures that the building is strong and durable.

The thickness of the insulation material in the sandwich panel varies according to the load-bearing capacity, regional conditions, the purpose of the building and the insulation value.

Investment economy

In many types of buildings, you can save building and installation time by choosing an appropriate sandwich panel. Thanks to its easy-to-install feature, you can carry out expansion and renovation projects without interrupting daily activities in the building. In addition, the panel can be disassembled and reused, which is economical and practical.

The lightness of the sandwich panel gives you advantages in terms of transportation and major construction costs. Moreover, due to its durable structure, its maintenance cost is very low.

In short, sandwich panels have a long service life, are a fast and beautiful solution, and are economical.

The aesthetic appearance of the building

The appearance of your building is like a mirror of your dreams. Therefore, we add new ideas to the sandwich panel every day to make your building beautiful. By designing the sandwich panels in different colors and structures so that they can be placed horizontally, vertically or obliquely, you can make the exterior walls of the building more vivid and get a beautiful appearance. Since their functions can also be used internally, you can use sandwich panels to create different designs.

High fire resistance

If you choose a sandwich panel that is suitable for your building in terms of fire protection, you will be able to slow down the spread of fire in the building and its surrounding environment and ensure the safety of life and property of the building.

When selecting a sandwich panel for fire protection, factors such as fire resistance, fire resistance time, size and height of the building, etc. should be considered, and sandwich panels with mineral wool or FM certified PIR cores should be preferred.

Air tightness and water tightness

Due to its perfect joint details, Teknopanel sandwich panels prevent air and water leakage. They ensure the continuity of insulation, but no heat is lost anywhere in the building. Therefore, you

can control heating and cooling in the building and ensure energy efficiency.

The sandwich panel has a waterproof structure to ensure effective water insulation under natural conditions (such as snow and rain) and prevent moisture and mold. Because they hinder the corrosion of load-bearing structures, they provide a healthy and comfortable environment for your building. Your building will become stronger and more durable.

Noiseless building

In order to minimize the harmful effects of noise on the human body, eliminate unnecessary sounds and reduce the sound spread from noisy areas, sound insulation measures must be taken.

With its mineral wool thermal insulation core and perforated metal sheet surface, it can achieve sound insulation. The sound insulation sandwich panels used for roofs and walls can create healthy and comfortable noise-free spaces and prevent workplace accidents, thereby increasing productivity.
