Galvanized Steel Insulated Sandwich Panels for Wall and Roof
An insulated sandwich panel is a construction material consisting of three layers: two outer layers of material (usually metal, wood, or plastic) and one inner layer of insulating material (usually foam or some other thermal insulation material). The outer layers of the panel provide structural support, while the inner insulating layer provides thermal insulation, allowing the panel to maintain a comfortable interior temperature in hot or cold weather.
Insulated sandwich panels are commonly used in the construction of walls, roofs, floors, and doors for both residential and commercial buildings. They are highly effective in reducing heat transfer and energy loss, and are known for their high strength, durability, and fire resistance. The panels are easy to install and require minimal maintenance, making them an attractive choice for both new construction projects and retrofits of existing buildings.

What are the Advantages of Sandwich Panels?
Some advantages of sandwich panels include:
Thermal insulation: The insulating property of the core material makes sandwich panels an ideal choice for structures where thermal insulation is a priority, such as cold storages, housing units, and constructions in regions with extreme temperatures.
Lightweight and easy to install: Sandwich panels are lightweight and easy to install, hence require less labor and machinery. This translates to a quicker project turnaround time and cost savings.
High strength and durability: Sandwich panels have high strength and durability, making them able to withstand high loads, stresses and forces.
Aesthetically pleasing: Sandwich panels are available in different colors, finishes, and textures, making it possible to customize the appearance of the structure to meet the desired standards and look, thereby increasing the aesthetic appeal of the building.
Fire resistance: Sandwich panels with a mineral wool core are known to have a higher fire resistance and can withstand flames for longer, due to the flame-retardant nature of the insulation material.
Easy to maintain: Sandwich panels require minimal maintenance, making it a cost-efficient approach in the long run.
Overall, the advantages of sandwich panels make them an attractive choice for construction projects in different sectors, including commercial, industrial, agricultural, and residential.
The size of sandwich panels can vary depending on the manufacturer and desired application. The thickness of the panels can range from 50mm to 150mm, and the width is typically 0.95 to 1.2 meters. The length can be customized to meet the specific needs of the project, with typical lengths ranging from 2 to 12 meters.
The standard thicknesses for sandwich panels are 50mm, 60mm, 75mm, 100mm, 150mm, although some manufacturers may offer other thickness options as well. The thickness of the core insulation material determines the R-value of the panel, which measures the thermal resistance of the panel and its ability to restrict heat flow.
Sandwich panels are commonly used for roofing in both residential and commercial buildings. This is because sandwich panels offer several advantages over other roofing materials:
Thermal insulation: Sandwich panels have an insulation core that provides excellent thermal insulation, making them ideal for cold and hot weather conditions. This can help to reduce heating and cooling costs, making them an energy-efficient roofing option.
Lightweight: Sandwich panels are lightweight compared to traditional roofing materials like concrete or tiles, which makes them easier and cheaper to transport and install.
Durability: Sandwich panels are highly durable and can withstand harsh weather conditions such as strong winds, hailstorms, and heavy rainfall. They are also resistant to corrosion and humidity, which makes them ideal for coastal areas or areas with high humidity.
Airtightness: Sandwich panels are designed to be airtight, which means they can provide an effective seal against air leaks and drafts. This improves indoor air quality and can reduce the occurrence of mold and other indoor pollutants.
Customizable: Sandwich panels are available in a wide range of colors, sizes, and thicknesses, which makes it easy to customize the roofing solution to meet specific aesthetic and thermal insulation needs.
Quick installation: Sandwich panels are easy to install and require little maintenance, making them a quick and cost-effective roofing option for both new construction and renovation projects.
Overall, sandwich panels are an excellent roofing option due to their many benefits, including thermal insulation, durability, light weight, airtightness, customization, and quick installation.
Sandwich Panel Insulation Type Selection Guide
The functions and needs of every building are different. Sandwich panel choice thus varies according to the thermal, acoustic, and hydro insulation and fire resistance needs of your building. Selecting the insulation core in accordance with the need of your building positively affects the performance you will obtain from the sandwich panel.
You can select the insulation material suitable for the features and needs of your building from the Sandwich Panel Selection Table we prepared for you.
