The efficiency and structural advantages of sandwich panels make them a highly versatile building material that is used extensively in contemporary construction. With their three layers—a core material sandwiched between two outer skins—they are incredibly strong and lightweight, with excellent thermal insulation. Because of their composition, which insulates against noise, heat, and cold, they are perfect for facades on both homes and businesses.
Depending on the desired qualities, sandwich panels can have a variety of core materials. Mineral wool, polyurethane (PU), and expanded polystyrene (EPS) are common core materials. While PU panels provide better thermal insulation, EPS panels are more affordable and lightweight. Because of their superior acoustic insulation and fire resistance, mineral wool panels are appropriate for settings that need to reduce noise and improve safety.
Sandwich panels’ prefabricated design, which enables quick installation and drastically cuts down on construction time, is one of its main benefits. Their modular design and uniform sizes make assembly easier, which lowers costs and improves operational effectiveness. The thickness, color, and finish of these panels can be altered to meet a variety of architectural needs and aesthetic tastes.
Sandwich panels not only have structural and thermal advantages, but they also support green building techniques. Their energy-efficient qualities contribute to lower heating and cooling expenses, which in turn reduces the overall energy consumption and carbon footprint of a building. In addition, their resilience and minimal upkeep needs foster enduring sustainability, rendering them a favored option for environmentally conscious building endeavors.

New building materials
Sandwich Panel, also known as sandwich-multi-layer sandwich in English, is a three-layered building material made up of an insulating layer sandwiched between two layers of hard material (such as metal, PVC, etc.). Presses layers together with heat or cold.
The American architect Frank Lloyd Wright created and employed this building material for the first time in 1930. Up until the 1970s in the previous century, product design was improved and changed.
In 1974, a variety of panels made their appearance in Russia. They currently hold the top spot when it comes to installing a quickly growing structure.
Application area
Three-layer completed building materials are in demand by builders due to their attributes:
- The simplicity of the material.
- The ability to solve complex architectural plans.
- Installation speed with a combination of strength and lightness.
In essence, they discover their calling in the construction of frame-by-hand homes. Products are used in the construction of single- and multi-story private structures. They are fixed to a metal frame that is already in place.
These lightweight, long-lasting materials can be used to construct a utility room, garage, cottage, or country house on a garden plot.
Products used in the construction of public buildings, such as stores, restaurants, offices, gyms, and warehouses. The ease with which these structures can be updated, expanded to a higher floor, and disassembled is the reason.
Large industrial structures can be installed more quickly and easily thanks to the dimensions of these construction industry products, which allow panels up to eight meters in length to be ordered.
Types and properties of panels
The products’ functional purposes vary in the following ways:
Wall products are employed in the construction of residential buildings, commercial buildings, industrial buildings, warehouses, and other structures as external enclosing structures. The components that make up the enclosing structures can be positioned horizontally, vertically, or inclined.
Installing interior fences, arranging interstory floors, and installing flooring are additional ways to use building materials. They are frequently employed in the reconstruction of buildings.
Roofing products are different from walls with a thicker layer of galvanized steel cladding because they are used for roofing.
Wall sandwich panel standard sizes:
- Length from 3 to 8 m.
- Width 120 cm.
- Thickness from 10 to 30 cm.
The following measurements may be used for the roof:
- Length maximum 16 m.
- Working width 1 meter.
- The thickness of the sandwich panel from 4 to 16 cm.
Traditional three-layer products (glued) are produced in a factory setting. However, there is an additional method of producing these construction materials: the elemental assembly sandwich panel. Three different types of components are assembled on-site at the construction site: an outer layer (corrugated board), insulation, and a self-supporting profile. Although these building materials are less expensive, they require more time to construct.
Wall panels can be smooth, simply profiled, or decoratively profiled (under wood), depending on the type of coating. One or both sides of roofing components can be profiled.
Sandwich panels are covered with galric steel, aluzink, drywall, plastizol, polyester, and ceramic materials.
Thermal insulation can be made of mineral wool, fiberglass, polystyrene foam, polyurethane foam, or a combination of materials. While selecting a material during the structural design phase, one must consider the benefits and drawbacks of each type of thermal insulation. However, every kind of thermal insulation used in the production process is robust and environmentally friendly.
| Sandwich Panel Feature | Size Specification |
| Insulation Core Material | Typically foam, mineral wool, or polyurethane; chosen based on thermal efficiency and fire resistance. |
| Facing Material | Often steel or aluminum sheets; provides durability, weather resistance, and aesthetic options. |
| Panel Thickness | Varies from 40mm to 200mm, influencing insulation value and structural strength. |
| Panel Length | Customizable up to 16m, facilitating faster installation and fewer joints. |
| Panel Width | Standardly 1m, offering ease of handling and compatibility with construction norms. |
Sandwich panels are an adaptable building material with a reputation for strength and efficiency. They provide outstanding durability, soundproofing, and thermal insulation because they have an insulating core sandwiched between two outer layers. They are perfect for a variety of applications in building facades because of their construction design.
Sandwich panels can be made to any size or shape, which is one of their main advantages. Offering a variety of thicknesses, usually ranging from 40mm to 200mm or more, they can be customized to fulfill the unique load-bearing and insulation needs of various structures. Its adaptability enables structural integrity to be maintained while optimizing energy efficiency for architects and builders.
Mineral wool, polyurethane (PUR), and expanded polystyrene (EPS) are common components found in sandwich panels, and each has specific benefits. PUR panels offer the best thermal insulation, while EPS panels are more affordable and lightweight. Because of their well-known acoustic qualities and fire resistance, mineral wool panels are a good fit for settings that value noise abatement and safety.
Sandwich panels offer advantages for contemporary construction projects that go beyond their practicality and visual appeal. Because they are available in a range of hues, textures, and finishes, architects can accomplish a variety of design goals without sacrificing functionality. Sandwich panels help create energy-efficient and aesthetically pleasing facades for buildings, whether they are used in commercial, industrial, or residential settings.
This is a succinct main thesis statement for your paper on "Sandwich panel features: structure and size": Optimizing building facades requires an understanding of sandwich panel dimensions and structure. These panels combine strength and insulation because their outer layers are bonded to a core material. Architects and builders can choose the best panels for energy efficiency, longevity, and aesthetic appeal in contemporary construction projects by investigating their various sizes and configurations.
