Sandwich panel is a modern material that has successfully replaced materials such as brick, cement, and sand. Sandwich panels or prefabricated panels come in various types, each of which has unique features and specific uses. Understanding types of sandwich panels and their uses plays an important role in choosing this product. In this article, we will discuss the use of various types of sandwich panels.
Types of sandwich panels and their applications
A sandwich panel consists of a central insulating layer and an outer covering section. The materials of the intermediate insulation and the sandwich panel covering sheets are different, which is what makes each combination in the manufacture of a sandwich panel have a specific feature and application.
Typically, Polyurethane insulation foams, rock wool, glass wool, and polystyrene are used as the central core, and aluzinc, galvanized, aluminum, and kraft paper coatings are used in the manufacture of sandwich panels.
In terms of application, sandwich panels are divided into two categories: wall sandwich panels and ceiling sandwich panels. Below you will learn about each of them, their features and uses.
Roof sandwich panel
Roof sandwich panels As their name suggests, they are used in the roof of structures. These sandwich panels usually use polyurethane foam as insulation. Polyurethane has a very low heat transfer coefficient, which prevents heat and cold from easily penetrating the building and prevents energy loss. This foam is also a good insulator for sound.
Another characteristic of sandwich roof panels is their long pitch. Trapezoidal and overlapping pitches are used to prevent water from entering the roof panels due to rain and snow. Aluzinc and galvanized sheet coverings are usually used in sandwich roof panels.
Sandwich wall panel
This type of prefabricated panels is used in the wall covering of various structures. Wall sandwich panels have fewer ups and downs compared to ceiling panels and are produced in two types: male and female. In this way, during installation, these parts are well connected to each other and completely eliminate the seams. Sandwich wall panels are considered good insulators against moisture and humidity.
Their thickness is also less compared to ceiling sandwich panels. The standard thickness of these sandwich panels is from 4 cm to 20 cm. In the manufacture of wall sandwich panels, polyurethane, polystyrene and XPS foam insulation types are usually used.
Application of sandwich panel types
Sandwich panels are used in various industries due to their features such as being lightweight, inexpensive compared to traditional materials, quick and easy installation, etc. Sandwich panels are generally widely used in chemical industries, industrial and manufacturing centers.
The use of sandwich panels is very common in the construction of housing, recording studios, containers, cold storage, gazebos, factory roofs, sheds, warehouses, etc.
Application of sandwich panels in construction
Benefits such as moisture, sound, and heat insulation, easy and inexpensive installation, lightweight structures, diversity in production, etc. have made sandwich panels an excellent choice in the construction industry. In construction, various types of ceiling and wall sandwich panels are used. Various types of sandwich panels such as aluzinc, aluminum, galvanized, etc. are used in this industry.
Application of fireproof sandwich panels
In fireproof sandwich panels, rock wool and glass wool are used as the insulating core. Also, their coating is often made of galvanized or aluzinc. These types of sandwich panels are known as fireproof sandwich panels due to their features such as very low heat transfer coefficient and high resistance to direct flame. These sandwich panels are generally used in structures where the risk of fire is high, including the construction of industrial factories and laboratories. Fireproof sandwich panels do not easily catch fire when exposed to direct flame and do not melt or deform after a fire. Their damage in a fire is very minimal, and since they have very high strength, they can also be used as second-hand sandwich panels.
Economy Sandwich Panel Application
Economy sandwich panels are sandwich panels with polystyrene insulation. These sandwich panels use polystyrene insulation, or Unolite, in the center. This type of sandwich panel is considered the cheapest product on the market and is very popular due to its economic and cost-effectiveness. Although this type of sandwich panel can be used in a variety of structures, it should be noted that its heat transfer coefficient is very high and it is not considered a good insulator for heat. In addition, it is vulnerable to direct flame and easily catches fire and melts.
Construction of clean room
A clean room is a special type of structure in which the presence of contaminants, microbes, and viruses is strictly controlled.
In fact, a clean room is completely sterilized. These rooms are used in the medical, laboratory, aircraft manufacturing, petrochemical industries, etc. Sandwich panels are considered the best product for building a clean room. For more information, see the article Clean Room Sandwich Panel.
summary
Sandwich panels are a modern material in the construction industry that is very popular due to its unique features. Features such as being lightweight, inexpensive, insulating, and able to be manufactured according to customer needs and applications, etc., are among the features of sandwich panels. Sandwich panels come in different types in terms of the materials used in their construction and applications, which are mentioned in this article.
