Advantages of Roof Sandwich Panel
Durability & Long Life
This is one of the biggest and most important advantages of roof sandwich panel. These panels are made up of high-quality materials designed to withstand harsh temperature conditions like strong winds, heavy rain, and extreme temperatures. Also, they are highly resistant to corrosion, which means they won't deteriorate over time.
Energy Efficiency
This is yet another benefit of the sandwich roofing panel. The panels are designed in such a way that they offer excellent insulation. This means they can keep the building warm during the winter months and cool in the summer months. Therefore, it helps you save money on your energy bill because you won't have to rely on the cooling and heating systems. Sandwich roofing panels are great at reducing heat loss, which can help create a comfortable environment for the occupants of the building.
Water Resistance
Sandwich panels are great water resistant. Therefore, they are an excellent choice for buildings located in areas that have high rainfall. These panels offer a water interlocking mechanism that helps prevent water from seeping through the roof. It also helps to prevent leaks and water damage. The insulation layer within the metal sheets will also help prevent water from seeping through the roof. The insulation layer will create a thick lock, allowing water to penetrate these panels and preventing it from entering the building.
Sound Insulation
Along with excellent thermal insulation, roof sandwich panel are ideal for reducing sound transmission. This is because the insulation layer helps absorb sound waves, stopping them from passing through the roof and building. This is why sandwich roof sandwich panel are great for buildings that are placed in noisy areas like airports or busy roads.
Types of Roof Sandwich Panel

Thickness of Roof Sandwich Panel
Roof sandwich panel consist of two outer layers and a core material sandwiched in between. The outer layers are typically made of steel or aluminum, while the core material is often composed of insulation materials such as polyurethane foam, polystyrene foam, or mineral wool. The thickness of the roof sandwich panel is determined by the specific requirements of the building and the intended use of the roof.
The thickness of roof sandwich panel can range from 30mm to 150mm, with common thicknesses falling within the range of 40mm to 100mm. The choice of thickness depends on factors such as the climate conditions of the area, the desired level of thermal insulation, and the structural requirements of the building.
For regions with moderate climates, a thickness of around 40mm to 60mm might be sufficient to provide adequate thermal insulation. However, in areas with extreme weather conditions, a thicker panel with insulation properties in the range of 80mm to 100mm might be more suitable to ensure effective temperature regulation and energy efficiency.
Type of PU Foam Is Used in the Roof Sandwich Panel
Flexible Polyurethane Foam
Flexible polyurethane foam is a type of foam that is commonly used in cushioning and comfort applications. It is known for its softness, flexibility, and ability to conform to different shapes. Flexible polyurethane foam is widely used in mattresses, upholstery, car seats, pillows, and other comfort products.
Rigid Polyurethane Foam
Rigid polyurethane foam is a type of foam that is used for insulation and structural applications. It has a closed-cell structure, which makes it a good thermal insulator. Rigid polyurethane foam is commonly used in building and construction as insulation material for walls, roofs, and refrigeration applications. It is also used in various industries for manufacturing lightweight structural components.
