Description
Fireproof Insulation Rock Wool Polyurethane PU Wall Panel and PPGI Roof Sandwich Panels
Roof sandwich panel is a combination of two layers of thin steel plates sandwiched by polystyrene, polyurethane, rock wool and other thermal insulation materials. Sandwich panels are usually used in building exterior walls, roofs, cold storage, workshops, etc., and have excellent properties such as heat insulation, fire prevention, sound insulation, earthquake resistance, and waterproofing.
The outer steel plate of the sandwich panel is made of cold-rolled, hot-rolled, galvanized sheet and other materials, and the insulation material filled in the middle includes polystyrene, polyurethane, rock wool, etc., and its thickness is generally between 50mm-200mm. Due to the advantages of light weight, high strength, heat insulation and fire prevention, sandwich panels are widely used in the construction industry at home and abroad. It is widely used in building materials, especially in places with high demand for heat insulation and fire protection, people's demand for sandwich panels is increasing.

How big is a sandwich panel?
The commonly used dimensions of sandwich panels vary according to different applications and requirements. Here are some commonly used sizes for reference:
1. External wall sandwich panel: common specifications are length 2-6m, width 0.95m, thickness 50-100mm;
2. Roof sandwich panels: common specifications are length 2-12m, width 0.95m, thickness 50-100mm;
3. Cold storage sandwich panels: common specifications are length 2-15m, width 950m, thickness 50-200mm;
4. Workshop sandwich panel: common specifications are length 2-12m, width 950m, thickness 50-200mm;
5. Sandwich panels for box houses: common specifications are length 2-6m, width 950m, thickness 50-100mm;
It should be noted that the size of the sandwich panel can also be customized according to the specific requirements of customers. When ordering sandwich panels, customers need to provide specific size requirements, as well as required materials, colors and other information.
How should I choose the panels?
Rock wool sandwich panels, foam sandwich panels and Pu (polyurethane) sandwich panels are common sandwich panel types that differ mainly in terms of materials and properties.
1. Rock wool sandwich panel: The filling material of the sandwich panel is rock wool, which is often used in building heat insulation, fire prevention, sound isolation and other fields. The advantage is that it has good heat insulation, fire prevention, and sound absorption effects, and is suitable for most indoor or outdoor environments, and the price is relatively economical.
2. EPS sandwich panel: The filling material of the sandwich panel is EPS, which is often used in construction, cold storage, container, vehicle and other fields. The advantages are light weight, good heat insulation, and relatively low price.
3. Pu sandwich panel: The filling material of the sandwich panel is polyurethane, which is often used in construction, cold storage, container, vehicle and other fields. The advantages are good heat insulation performance, good heat preservation effect, high fire rating, excellent mechanical strength and corrosion resistance.
Therefore, which sandwich panel to choose mainly depends on its specific use occasions and require. EPS sandwich panels are suitable for cold storage, containers and other occasions that require heat insulation and heat preservation; and Pu sandwich panels are suitable for buildings and vehicles. And other occasions that require heat insulation, heat preservation and fire prevention.
How to select roof sandwich panels?
Select Roof sandwich panels (roof sandwich panels) need to consider the following factors:
1. Thermal insulation performance: The roof sandwich panel is mainly used for thermal insulation, so the thermal insulation performance of the sandwich panel should be considered. The insulation performance of sandwich panels is usually related to the type, density and thickness of filling materials. Based on actual needs, the corresponding sandwich panels can be selected for insulation.
2. Quality: The quality of the sandwich panel has a great influence on the insulation effect, waterproof performance and service life of the roof, so it is necessary to choose a good quality sandwich panel. Generally speaking, the quality of the sandwich panel has a lot to do with the brand, and the quality of the sandwich panel of a well-known brand is relatively good.
3. Thickness: The thickness of the sandwich panel is usually determined according to specific needs. When choosing a roof sandwich panel, it is necessary to consider the local climate conditions, use requirements, and building characteristics to determine the appropriate thickness of the sandwich panel.
4. Waterproof performance: The waterproof performance of the roof sandwich panel also needs to be considered. Some sandwich panels may not have good waterproof performance, and additional water-retaining processes are required to protect the roof, while some sandwich panels are inherently waterproof.
5. Ease of installation: When choosing a roof sandwich panel, it is also necessary to consider whether it is easy to install. Some sandwich panels may be difficult to install, which will increase the complexity and cost of construction, so it is necessary to choose relatively simple and easy-to-operate sandwich panels.
To sum up, the selection of Roof sandwich panels mainly needs to be based on the actual situation and specific needs of the building.
Sandwich Panel Advantages
Roof sandwich panels are an innovative and cost-effective solution for modern construction. Sandwich panels consist of three layers - an insulated core of high-density foam or mineral wool, a top layer known as the "skin" and a bottom layer.
The skins can be made of various materials like metal, wood, plastics, and composites. The bottom layer is typically the same material as the top layer.
One of the key advantages of roof sandwich panels is their thermal insulation properties. The insulating core is designed to provide excellent resistance to heat loss, which enables them to keep the indoors comfortable during extreme weather conditions.
Moreover, roof sandwich panels are lightweight, easy to install, and cost-effective. Due to their modular design, they can be rapidly installed, reducing construction time and overall costs.
Another aspect of roof sandwich panels is the durability and longevity they offer. The insulated core provides protection against moisture penetration, which reduces the risk of corrosion, mold, and rot.
Roof sandwich panels also offer superior acoustic insulation and noise reduction. This makes them an ideal choice for buildings that are close to busy roads or railways or in noisy industrial areas.
In addition, roof sandwich panels are environmentally friendly. The insulating core is made from recycled materials, and the panels themselves can be recycled once they reach the end of their life cycle.
In conclusion, roof sandwich panels are a smart choice for any construction project. They offer thermal insulation, durability, acoustic insulation, are environmentally friendly, and cost-effective. With their modular design, they can be installed quickly and easily. The future looks bright for this innovative roofing solution.
